Lost Wifi after Win10 upgrade from Win 7

Q: Lost Wifi after Win10 upgrade from Win 7

I upgraded a few days ago on my ACER Aspire 605G from Windows 7 to Windows 10 and I lost wifi capability. After upgrading numerous drivers, The Qualcomm Atheros Wireless LA Driver gave a message that said, "The device may not be present or could have been ejected/unplugged from the system. Insert or reinsert now." Is that the root of the problem. How do I fix the wifi access? Thanks for your help.

Preferred Solution: Lost Wifi after Win10 upgrade from Win 7

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Power outage due to storm. Came back on without pictures and documents. It's an HP desktop. Would a file recovery program work? I've tried some of the instructions online, but they don't work.

I have G41 M/B + Core 2 Duo .2.40G E4600 & 2Gb GSkill RAM (F3-10600CL9S-2GBNT, DDR3-1333 PC3-10600)
Now I want to Add More 4GB + current 2gb.
Which RAM will compatible with my above configuration.

A:RAM Upgrade

If you are planning on using the current RAM also than you should stick with same RAM manufacture. You will have less issues that way. Without knowing exactly what your motherboard make and model is (G41 does not supply enough information about whom the manufacture is and what model), I am unsure how many RAM slots you have total and how many are in use). Try this link (Newegg - GSkill RAM) and you can choose which one fits your budget.

I recently decided I'm going to start using my old laptop again. I swapped the hard drive for an SSD and I'm quite pleased with the performance boost that got me. I am now looking for a ram upgrade from 2gb to 8gb.
I have a Dell inspiron n4010.
I went to crucial's website and did the system scan. The scan said that this would fit my needs.

Unfortunately, crucial doesn't ship to me. I'm forced to look elsewhere. I looked for something similar on another store's website. My question to all the experts out there is: will 2 of these work with my laptop and get me the 8gb of ram I need?
thanks for the help!

A:Quick ram upgrade question

Yes. The specs are exactly the same. Over the years I have used both Kingston and Crucial many times for memory upgrades and both are excellent.

You can also do a memory scan at Dell's own website. Just don't buy what they offer because they'll tell you to only buy genuine Dell memory blah, blah, blah. The Kingston will do you quite fine.

A:My Laptop won't connect to Wifi, but will connect with an Ethernet cord

How far from the router are you? I experience the same thing occasionally on my laptop.
I usually have to switch the wifi switch off on the laptop & on then I reboot & I'm back online. My laptop & tower are both about 50' away & on the lower floor where the router is. Good luck.

Okay so before I begin I'd like to say I am relatively new to computing and I'm not the most knowledgeable.

Let me explain my setup:
I have a HP Envy SleekBook Laptop which is connected to my BT Wifi through a NetGear HomePlug which should give me wired internet.

I cannot move the router which is that the other side of the house and I decided to test me internet speed on I got nearly exactly the same values when using the ethernet cable and when connecting to the internet.

I often have ping spikes and lag in CS:GO.

That is my main issue and my secondary discussion is if this is a good setup : (I have ordered this stuff)

Thanks <3

I recently used a program Autoruns,, and deleted some startup things I shouldn't have.. Since then I cant connect to internet, the troubleshooter for wireless adapter says the Windows wireless service is not running on this computer (WLAN Autoconfig service) and fails to start the service.
I notice on windows task manager there are only about 13 Processes running and there are usually about 20, and on Services there are about 40 running and about 100 or more stopped services. Thanks for the help

Also on startup now I have a pop up on bottom saying, Failed to connect to a windows service. Windows could not connect to the System Event Notification Service service. This problem prevents standard users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn't respond. And the startup and logon time is really long now

Sounds like you deleted the network drivers, I did this once and ill be honest unless someone here knows a trick, or you have a CD with drivers you are going to have to have a hell of a time unless you know the name of the hardware and download the right driver, thats my guess. best of luck

I have an older eMachines Desktop PC model EL1360G which has a 200 watt power supply.
I would like to upgrade it to at least a 400 watt power supply.
Does anyone have a suggestion as to where or what I should buy? I watched a few videos on youtube on how to do the replacement but how do I know all the plugs on the new unit are the same and will fit? Because if they don't, I'll be more confused than I already am.

A:Emachines power supply upgrade

Check and make sure all the connectors are the same as the ones you have

I'm not certain if the image above is what you have but I'm thinking it is.

Image above looks to have:

1x 20pin+4pin (ATX Power)

1x 4pin (P4)

2x SATA power
Does your power supply have these and only these?

Hey guys,

I have a Sony Vaio VPCEH15EN laptop & the OS is Windows 7 home basic. I have a wifi router which is of TPLINK.

The wifi won't connect to my laptop but it works fine on my would only start working when I use the ethernet cable. I never had this problem before. I have tried everything ..I also tried the winsockfix.bat but all my efforts have gone in vain..I just don't know if the wifi router is faulty or the modem of my ISP...Please help me solve this problem.

Best Regards,

A:Wifi on my laptop won't work but works when I use the ethernet cable

I have solved the problem by myself. To do this, first you have to disconnect your Ethernet cable from your laptop and follow the steps: Start>Control Panel>Network and Sharing Center>Manage Wireless Networks and remove all wireless connections by right click on it and select Remove network from the drop down menu. After doing this, close the windows and scan for the Wi-Fi networks. Click on the available network and select connect. After a while, you will be asked to give a password for your Wi-Fi connection. Type the password and click on connect button. And now will be connected to your Wi-Fi network via wireless.

May be it will help you.

Hey, im planning on upgrading either my cpu or my gpu, and I need to know what would give me a more
noticeable increase in performance in gaming.

The gpu I currently have is a gtx 760, and my cpu is an i5 - 4430 3ghz
the cpu I'd upgrade to is an i7 - 4790k 4ghz, and the gpu I'd get is a gtx 970.

So which one should I upgrade?

A:Need advice on what to upgrade

The i5 is considered the so-called sweetspot for gaming and since games are gpu intensive I would upgrade the gpu first.

A few questions for you:
1. How much RAM do you run?
2. Are you getting any lag in gaming? What is your current average FPS?
3. What do you hope to gain that would make your gaming experience noticeably increased?
, Make and wattage output of your power supply?

My phone and my laptop both see it and connect with full strength.

What do I do?

A:Netgear N300 can't see wifi

Try the factory reset. There's a a small reset button in the back, press it down (sometimes you have to use a pen if it's one of those pin hole things) for about 5 seconds and that takes it back to factory settings. At that point you can either run the install CD that came with the router, or set it up manually from your browser.

I am looking to upgrade the GPU on this PC but I am unsure if the PSU will be able to support it. I am not looking to install a high end GPU only a low end card such as ASUS 2 GB AMD Radeon R7 240-2GD3-L PCIe. I am aware that the PSU has a max of 220w but I am unsure of the current load.

Basic specs are:

Windows 7 64 Bit
Intel Core i3 2120
6GB Ram
Intel HD Integrated Graphics
2 HD (1 SATA 1GB)
1 Optical Drive
Realtek HD Audio

If necessary I am able to disconnect 1 HD and the optical drive as they are not necessary, also to disable the onboard graphics if possible if this will help.

Hi there,

The laptop I have is an asus P550C, windows 7.

This laptop came pre-installed with Mcafee Antivirus protection for a limited amount of time. Wifi was working perfectly fine although there were occasions where the connection would disconnect by itself. After the free-trial ended, I did not want to buy the packaged they were advertising so I went to my Control Panel and uninstalled Mcafee. This was when the problem started to occur. The internet access icon had a red x and when I went to diagnose the problem, it said that I needed to connect via an ethernet cable. Since then, I have connected it with an ethernet and internet works and I have also installed AVG's free antivirus software.

I have tried to
type: ipconfig /flushdns
type: nbtstat -R
type: netsh int reset all
type: netsh int ip reset
type: netsh winsock reset

But I still cannot connect via wifi. Please help

Hello Here is a quick summary for those who don t want the whole shebang I need suggestions for a good ATX motherboard and CPU that will handle simple games like Roblox and p movie streaming I have a nearly year old desktop computer nothing special at all It is the family desktop so it will not be used for anything other than super light gaming my nephew plays Roblox CPU/Mobo upgrade non for gaming on it surfing and watching movies I bought a BenQ p monitor for my own gaming PC and connected it to both that and this desktop to give the rest of the family a bit of an upgrade I noticed right away that the computer CPU/Mobo upgrade for non gaming already performed slower with this higher resolution It is also running a -bit processor and I have a copy of windows pro bit that I want to put on that machine so I need suggestions for a CPU and mobo that will run me less than buying a new computer from scratch The parts are all good and well maintained I just want to upgrade to bit so that we can take advantage of the free upgrade to windows and possibly even adding more memory in the future if my nephew starts playing higher quality games as he gets older EDIT my only requirement is that the motherboard must be full ATX since I do not want to replace the case Any suggestions are welcome Thank you nbsp

If you do indeed have a full ATX case, it will fit mATX as well as miniITX motherboards.

What exactly is your budget?

Newegg has kits anywhere from $100 to $800. -

These are nice kits for around $300
I know you said you didn't want to replace the case but for around 300 this is not a bad deal
You can find lower prices at Tigerdirect with smaller bundles. -
In my opinion don't get a kit with Celeron or Pentium, unless you are planing an upgrade in the future to i5 or i7. Bewarned though that Intel pricing doesn't fall as quickly as one would hope.

As for AMD suggestions, you'll need to speak with someone else. I'm not an AMD follower. I will admit that for the best savings AMD is the way to go. But then performance wise they struggle to compare to Intel, when you match prices. Which is the very reason I advised not to get Celeron or Pentium. The i3 or comparable AMD is the perfect performance level to be. Anyone needing more power will know they need more.

However, during the installation, it failed (again) due to either my antivirus or the aforementioned driver issues. Upon logging back in, my computer was unable to find any WiFi networks. Seeing as I live in the middle of a densely populated city, this isn't possible. Plugging in an ethernet cord still works, so no issues with that adapter or my home internet. I checked all the drivers for my WiFi adapter, and my Ethernet adapter, and both are up to date and display as working properly. Restarting several times didn't seem to fix this issue, and using system restore didn't seem to work either. I used the Troubleshooting tool, and that didn't give my any helpful advice or answers, so I got nothing.

What can I do to fix this issue?

For reference, I have a Broadcom 802.11ac Network Adapter, Driver Version, and a Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller, Driver Version

The Samsung rv510 laptop I have has a rubber plug blocking the HDMI port.
I assume it's because they use the "Case/Shell" for multiple models and this one does not come with it.
My questions:.... Are these built into the mobo or is there a Video card I could replace inside?
I'm assuming it's onboard in which case I will need to get a VGA+3.5mm audio to HDMI adapter in order to make this work?

It appears you have a portable device that likely doesn't have upgrade options. If your device maker doesn't list upgrade options on their website, you can likely scratch this idea.

Portables (Phones, Tablets, Netbooks, and Notebooks) are not designed with upgrading in mind. They are small and very limited with cooling capabilities. And most of the time everything is integrated in small form factors and can not be replaced.

Hi guys, while playing DOTA 2 (on lowest settings), I am experiencing the problem that my FPS is down to 30 almost all of the time. This started about a month ago and is really annoying to me, which is why I decided to updgrade my hardware in order to fix this problem. Now I am facing the problem though that I have no idea which parts of my hardware cause the low performance and thus need to be exchanged, some help would be very much appreciated.

I have the Medion Erazer X6817 with the following hardware:

CPU: Intel Core i7-2670QM @ 2.20 GHz
Graphics Card: NVIDIA GeForce GTX 560M

OS: Windows 7 Home Premium, 64 Bit
Some Additional Facts:

I use a LG 24MPHQ Monitor to display the game at 1920x1080 resolution
When playing RAM usage is constantly at about 3,2 GB, CPU Usage pending between 15 and 45
So what part of my notebook do I have to upgrade to improve my FPS?

If you can upgrade your RAM to 8 gigs that might help; it seems to be the sweet spot for gaming. Otherwise Dota 2 is not that demanding on hardware.

Hey guys,

I am planning on upgrading my computer eventually so that I can play Star Wars Battlefront 3 when it is released at ultra super eye candy settings with extra bling bling with 60 FPS when it is released.

I am currently running the following setup :

i5 4570. Never goes over 40c under load.
GTX 780ti HoF
8 GB RAM Corsair vengeance

So I can play most games today without any issues, but I had some issues with Farcry 4 on ultra settings (runs fine on High most times ) so now I am worried if I can run Battlefront 3 when it comes.

So my thoughts are if I should only upgrade my CPU and it might be enough?

OR if I should get another 780ti Hof to run SLI? This worries me though since I have had my current 780ti for about 1 year and it would suck if it would break in a year and I would be stuck with 1 card and the whole investment would be for nothing (Or very expensive atleast)



A:Upgrade CPU or go SLI?

First, before investing anymore $ what are the publisher's recommended specs for Battlefront 3?

Second, there is some spirited debate whether or not the performance increase using SLI or Crossfire is really worth the cash layout. Personally, IMO, the cost compared to actual performance increase isn't worth it.

Third, the i5 is the sweet-spot for gaming.

* So find out first what the recommended specs are and take it from there...

I am looking to replace my tired Linksys WRT54G router that is about 10 years old. I love the router, and its even better with DD-WRT on it, but I'm starting to have troubles with the wifi dropping all the connects for a couple seconds when running all my wireless devices. I have 3 smart phones, 2 tablets, 1 Chromecast, a smart TV, and Roku + a laptop or 3 in my house right now, and it seems like its getting to be a bit much for it.
I have had to completely re-flash the firmware twice this year to get the wifi working again, so I'm thinking its time for replacement.
I have been thinking about just getting the new WRT54GL for $50, but I'm also thinking it might be a good idea to upgrade the wifi technology past wireless G .
I'm wondering if my Tablet (Nexu 9), and our smartphones (Razr HD Max) along with the Chromecast will take advantage of the new wireless standards and higher speeds or not? If they will can someone recomend a decent wireless router that takes DD-WRT nicely in the sub-$100 range? Thanks!

A:Looking for new Wifi Router - Will Tablet/Smartphone take advantage of new wifi Standards?

I been programming in Android/Linux since 2010 and there is code that supports VHT is Very High Throughput. Right now the standards are HT is High Throughput .

As for DD-WRT firmware is like your overclocking your router pushing it beyond the OEM limits. I use to use DD-WRT but had quit many years ago since the routers that used that firmware would fail too much.

So best to buy a better business type enterprise router wired then you can use WiFi router as AP or just get WiFi AP(access point). To me WiFi Router is also Wired Router, but to use just a wired router and use WiFi AP through a switch is better. If one or the other goes you can easy replace them. Where as if the WiFi Router fails you would need to replace it.

If you really want to use DD-WRT then Look at Buffalo WiFi Routers some come pre-installed with DD-WRT on them. Frankly you really don't need DD-WRT today because newer routers or WiFi routers are much better built and offer much more power NPU = network processor units and 128, 256, 512, 1GB of RAM some have Dual Cores.

If you still have the same problem, connect via your phone and in Device Manager, try to update the driver.

I am confused and have no idea where to start... I apologise in advance for the wall of text.

Recently I have been experiencing odd issues with my WiFi router ( at least I think its the router) ZyXel Keenetic Giga II. The most annoying of which is the periodic inability to load random webpages. For example, I might be able to load google but not any of the search results while at the same time being able to browse reddit on my phone or tablet. The pattern changed constantly and it doesn't seem to affect any particular web pages. Like I said - random. This happens once or twice a week and seems to be increasing in frequency. I have tried rebooting the router. Rolling back to factory settings, changing DNS. With no result. It only resolves itself when it "feels" like it and usually lasts from 5 min to several hours. It is also worth mentioning that I hardly ever use my laptop and most of the browsing and streaming is done using various mobile devices.

Any help in defeating my router would be greatly appreciated.

I got a new laptop recently (this past Sunday) and ever since I turned it on I've had horrible issues with WiFi. It's tothe point where I'm ready to return it to the store and just go without a computer. Keep in mind I'm not very tech savvy, so I might not know what you're talking about.

It's very slow and won't stay connected to the internet. 4/5 times it doesn't load the web page I'm trying to load and after about 5 minutes after powering on it disconnects from my Wi-Fi and refuses to reconnect. The troubleshooter says it's a router issue but resetting the router doesn't do anything at all and no other device in the house is having any issues. I haven't downloaded ANYTHING to it yet. In addition, when it /does/ connect to my Wi-Fi, trying to open any web page brings me to a "you are not connected to the internet" notice.

I have no idea what to do. I need a computer for work but I'm so sick of having problems with them.

A:Brand new laptop; faulty wifi process?

Set up the laptop next to the router where the signal should be strongest. Are you sure that you are connecting to your own wi fi network and router? When you switch on the laptop it will search for in range networks and when you spot your own you are asked to give the password before you can use the internet for the first time. If that's not happening maybe its logging you on to a neighbouring unsecured network (no password set) where the signal is weak. If I click on the wireless icon bottom right in my taskbar it brings up a choice of available networks. My icon looks like a set of steps and so the icon shows how strong the signal is. Check that you are connecting to your own router and see how strong the signal is. You mention other devices that work OK but haven't given any details.

Hard Drive 750 GB 5400 rpm SATA

A:Recommendations for my laptop upgrade

Unfortunately most laptops do not have the option of replacing components. Your options for this HP Laptop is: upgrading your RAM to 8GB (or more depending on how much max RAM the laptop allows) & changing the Hard Drive from the 5400 rpm to either a 7200 rpm or better yet a SSD. Laptops are not component swappable like the Desktop computers are. Most laptops have parts soldered in on the motherboard. You might be able to eliminate some "Lag" with the RAM and Hard Drive changes, but if you are looking for a drastic improvement, I would suggest a laptop more suited for gaming.

2. Shut down the Modem and router.
3. Power on the modem only. Wait 2 minutes or so.
4. Power on the router. Wait 2 minutes or so.

set LAN address of router one as you please (eg: )

set an address reservation for router-2's MAC -> a fixed, constant IP address on that same subnet (eg
set the DHCP range small (eg 2-32)
router-1 will control all auto-ip assignments for both routers.

Personally, I add another tweak;

reserve ip addresses for all of my devices into the low-end of the dhcp range (say 2-10) and
let 'guests' take addresses above 10
This gives the opportunity to allow file/print sharing to known systems (2-10) and disallow for the guests.

Hello abbasi ,
You can use your iPhone to log in the router and change the wireless settings, however this isn't usually recommended. If something goes wrong when configuring the wireless settings and you are not able to connect to the router you'll need a device that can be connected via Ethernet cable to restore the access.
If this router is supplied by your ISP you can ask them if they have remote access to it to change the password.

I was looking to upgrade my Dell Insprion 2330 all-in-one PC to a solid state drive, to improve the performance. Firstly, is this possible? If so, is it practical?

Currently I have the factory 2TB hard disk installed and it seems a shame to loose all that storage space. From what I have seen it may be possible to replace the blu-ray drive with a SSD instead? Primarily I would be looking to run my operating system of the SSD and then use the existing drive for the bulk of my storage. That being said I am not sure if I would want to loose my blu-ray player either. I don't use it all that much, but it is still nice to have it there. I understand I may need to make some compromises to make the upgrade, so hopefully someone will be able to point me in the best direction and tell me whether it is really worth it. My PC doesn't run slow my any stretch, but from what I have seen it can make a big difference!

Thanks in advance,


A:SSD upgrade for Dell Inspiron 2330, is it possible?

Technically speaking, yes you could replace the hard drive with an SSD. I have never changed anything (hardware wise) with an All-In-One unit, but it must be possible. If you are looking to keep the extra storage space, you could take the 2TB hard drive and put it in an external hard drive case and connect it to one of your two USB 3.0 ports. That way you still have storage space to use while keeping your Blu-ray drive and having a SSD for your Operating System and Programs. It wont be as fast as leaving it inside connected with a SATA cable, but it will be better then connecting it USB 2.0 or not using it at all. If you do go through with this "venture", take photos and document what you did each step and then post them up here. May come in handy for someone else in the future.

Fortunately I think the Core2 8300 still has a little life left. Especially for those that are on a tight budget.

Also, 8 gigs is more than enough for gaming. Unless you are doing video rendering and graphics intensive applications you don't need 12 or 16 gigs of RAM

A:Limited wifi acces at home, but not at other places

Hello maarten747 ,

As far as I can see from the ipconfig output your laptop doesn't seem to obtain IP address.
You could try configuring one manually to test this theory. Something like: IP address, Subnet mask:, Gateway:, DNS1:, DNS2: . Just keep in mind that the details listed here are just a guess as I'm not fully aware of the specifics of your home network and a static IP configuration for the wifi adapter is not a good idea actually, so once done testing change it back to obtain IP address automatically.

Also in what wireless operation mode is your DrayTek configured?
Do you have any other wireless devices that are connecting to the same DrayTek ?
When you connect your laptop with ethernet cable, is the ethernet cable connected to the same DrayTek or a different device?

Hello, I've had this problem for a good while and cant seem to find many answers. What happens is that I will be online and everything is fine untill my wife or daughter decide to get on to one of their devices that use the same wifi (ipad, ipod, phone) and everyone will get disconnected. After 2 or 3 minutes everyone will be able to connect again, for a few minutes at least, then we will get disconnected again. Rinse repeat.

Our router is a Belkin wireless G-plus mimo, Model# f509230-4
Modem is Westell model 6100, e90-610015-06
My wireless router in the bedroom connected to the PC is a linksys wusb6300 (blinks orange light at the time of dissconnect)

Any ideas on how we can stop constantly disconnecting each other would be greatly appreciated.

*just saw I posted this in the wrong place..ugh

Moderator note: Moved.

A:Disconnecting from internet when others use the wifi

Two suggestions:

First, make sure you have the latest firmware for that router

Second, after updating the firmware, access the router config and set the MTU to 1492.

This will stop packet fragmentation and all devices will then be protected from a packet reassembly overflow condition, failing all existing connections.

Hey, I was trying to setup an adhoc connection, but I'm faced with a dilemma.
I have internet via an ethernet cable, so I want to spread this wifi using my laptop's wifi connection.
However, whenever I connect the ethernet cable to my laptop and it's connected to the internet, the wifi light on my keyboard automatically turns red and the wifi router no longer works, hence I cannot create the adhoc connection.
After I remove the ethernet cable, the wifi light turns back on, and I'm able to create an adhoc network, but I won't have any internet to spread since, well, the ethernet cable is not plugged in...

I have an HP running on Windows 7.
Both ethernet and wifi adapters are fine.

How do I prevent my ethernet connection from shutting down my wifi router??

Thanks everyone!

A:Wifi router turning off automatically

Hmm; IMO, Windows is attempting to keep you out of hot water.

Your PC WiFi is not intended to act like an open hotspot. I you what 'guest' connects via wifi, you should manage that in the router setup (several have the option for guest vs lan users).

You were to create this kind of network:

router = = PC - - wif - - guests
The routing table needs special entries and in effect, you would be creating a dual-home environment (the guests could just as easily be a secondary ISP).

I have a window's 8 laptop. It is about a year old. A few months ago it just suddenly stopped getting a strong wifi signal in my room. The wireless router is in the other room. I assumed that it was just our router, a belkin, and started using an ethernet cable rather then replace it. However, I am visiting my girlfriend and the router is in her room. I took my laptop to the other room and suddenly I only have one bar of connection and nothing will load, like it does at my house. Even sitting right next to the modem get 3 to 4 bar signal strength. I have no idea what to do. I have ran virus checks and malware checks. Nothing turned up. I tried checking to see if my wireless driver needed to be updated but it says that it's up to date and functioning properly, which clearly it isn't. My wireless driver is qualcomm atheros ar9485 802.11. Please help.

What the title says. I bought a TP-Link WDR4300 and installed it, and everything works perfectly on every device except for my laptop (Windows 8.1 Lenovo G480, running Windows Defender as AV). When connecting wirelessly, I get access to the router, but it shows "limited", and it doesn't even let me get into the setup page ( and when I ping it, every packet is lost. Ethernet, meanwhile, works perfectly. I'd appreciate any suggestions on how to fix it.

I'd like to attach the ipconfig outputs but my command prompt is in spanish and some of the characters are missing in the .txt file, too. I don't know how to get the file in english.

@jobeard I saw one thread you solved in which you said to mention you so you could help. I'd really appreciate it. Thanks beforehand for any and all suggestions.

A:WiFi doesn't work, Ethernet does

Hi, You will always have to use the ethernet (Cat 5) cable to get into your router's software, at, all routers are set up like that for security reasons.
It's done that way so that no one can change your settings, passwords etc using a wireless connection, you must use the Cat 5 cable to make setup & security changes.
Did you get any setup software with the TP Link router?
If you get good internet access using Windows 8.1 using the ethernet cable, it
might point to possible wireless driver issues.
It might be worth downloading the latest driver for your WDR4300 from the TP-link website;

I'm really new to the tech/ computer world, and know next to nothing about graphics cards. I was wondering if someone could help me figure out what graphics card I can upgrade my computer to (if I can upgrade at all) I was wanting to buy the new Sims 4 game, but after having played a very slow and choppy Sims 3 for years on this computer, I'm ready to actually play a game smoothly without it freezing all the time.

Here's what computer I have:
Compaq Presario PC SR5601P
Processor: AMD Athlon X2 4400
Dual-Core Processor
Memory: 1 GB
Hard drive: 250 GB
Graphics: NVIDIA GeForce 6150 SE Graphics
Windows Vista SP 1


A:Unsure of what graphics card my computer can upgrade to

Sims 4 System Requirements & your PC system results

For Sims 4 according to the link above, your CPU GPU and memory is lacking for even the minimum system specs. We can recommend a GPU, but that's not all you need if you plan on playing Sims 4. And if you get a stronger GPU, chances are you will also need a stronger PSU. If 300W's is all you have for power, you are limited to sub $100 graphic cards. Which would be fine for Sims 4, but then you also have a CPU and memory that needs upgrading.

About a week ago, our cable internet connection went out. Before I had a chance to reboot the modem & router, my 11 year old decided to completely reset the router to factory settings! Ugh! This caused several issues: my home network is now gone, only a unsecured factory network is available. When I try to plug my laptop into the router via ethernet cord (in order to login to router and setup secure network) my computer will not recognize the router and won't connect to internet. I tried troubleshooting with my cable provider and they say it's in my computer (IP address will not reset) and he recommended I replace my network card. However, today when I brought my laptop to work, it will instantly recognize the wifi at work. So is it really my network card that is causing issues? Please help, I'm desperate and not tech too tech savvy!

A:I can't connect to wifi but connect with an Ethernet cable works, even when it isn't plugged in

It gets confusing as to which device is being used so as a guideline
disable one or the other (wifi vs wired) and don't allow both to be active at the same time. Technically, which ever device gets an IP address from your router will become the gateway to your ISP - - ignoring the connectivity of the second device to access your router.

With a laptop, we just toggle the keyboard to enable/disable wifi and the wired is easy - - just pull the cable out.

create a desktop shortcut to \windows\system32\devmgmt.msc
to control the devices (needs admin access)
expand [+] network adapters and you'll see the list
mine are

Dell Wireless 1502 ....
Realtek PCIe FE Family Controller
Just right-click->disable and you can always right-click->enable

The png posted shows both are enabled and the wired has the gateway.
If the cable is disconnected, this is quite impossible.

SO, first control which device is to be used and then make the connection.

A:Suggest a new Wifi Router

I have the Netgear N600 and I love it! It is a great all round router. It goes for $75 on Amazon and the Gigabit version goes for $5 more. I would avoid Belkin routers since I have heard bad things about them. The Linksys N900 router also seems to be a possibility.

I would highly recommend the Netgear router (N600) because it is a good value for the performance. Keep in mind, when looking for a router, you should probably ignore the mbps ratings since your connection is probably not realistically close to that level. Look at warranties, reviews, and reliability. We have a ton of devices connected to the router at once (at least 10) and it works fine. It makes me lag a bit when gaming from time to time but that isn't usually the case.

A:CPU upgrade

Not trying to discourage you, but have you ever replaced a motherboard in a laptop before? I have and it certainly was a pain to get done correctly. Honestly, if you do not have much experience doing these types of things, your best bet is to buy a newer laptop. Laptops and Desktops are almost two different worlds when it comes to hardware. Changing hardware out on a desktop is easier because you have more room, whereas laptops are compact and compressed down and much more difficult to swap out parts (especially Motherboards and CPUs because they have to be compatible with the laptop casing so that you do not have spacing or heating issues). You also might run into the problem that the hardware might not connect properly to the new motherboard (ie. Laptop Monitor wires not able to connect). Again, I'm not trying to discourage you, but if you want the change to be as easy as possible, you should look for a replacement motherboard that will work as a direct swap out to the old one.

A:Wifi boosting

What wi-fi router are you using? On some, you can change the transmission power setting.

Another option, if you don't mind tinkering, is get a wi-fi router that's compatible w/ custom firmware like dd-wrt. Flash the router w/ the custom firmware and configure it as a repeater bridge. I did this at my parents' house years ago. Bought a refurbished Linksys WRT54G2, after flashing and reconfiguring the router, I was able to extend the range.

Tomato is another customer firmware. Haven't used it so can't comment on the pros and cons.

Replaced the mobo (Gigabyte GA-78LMT-USB3), CPU (AMD FX-4300 Vishera), and RAM (G-Skill RipJaws 4MBx2) in an older system running WinXP (planning to upgrade to Win7 ASAP). Everything booted up just fine, but the HP keyboard and the Logitech mouse, both of which which work fine on another computer, aren't being recognized at all by the computer. No error messages, just not working. Not even lighting up. We've tried every USB port on the system, and even used a USB-PS/2 adapter to try it that way, to no avail. I'm out of things to try. My only thoughts:

1. Could USB be disabled in BIOS by default? If so, how do I change that without a keyboard and mouse, when I can't even access the BIOS?

2, Could the USB system on the new motherboard be defective? How do I test that?

3. Is there any possibility at all that it's related to the Antec 500W PSU--perhaps not enough wattage for this system? (Hard drives are all pretty old.)

I have an internet connection that I have extended to my Brother in law's house, next door. At the moment, I basically have two LAN cables coming out of my modem/router, one going to my computer and another, extended cable, going to his computer.
However, he wants to use his spare modem/router, which has wifi capability, to allow his son to use his own computer downstair with only wifi.
Therefore, will there be any conflicts if I simply splice in a Lan cable or add a lan socket for the second modem/router (wifi location.) at the appropriate point along Lan cable 2? See diagram below.
If there is a possibility of conflict what would be an alternate wiring method?


A:Adding extra wifi (modem/router) to my already extended network

Good drawing and this will work just fine. In fact, that's what I use to get access at the far end of the house. Here's the trick;

router#1(lan slot) ---- (lan slot) router#2 with wifi​
Notice that #2 WAN slot is left empty! This places all systems on the same subnet of the router#1 {what you are doing is making router#2 act like a switch which has wifi support (y) }

* Give router# a unique LAN address (If #1 is, then make #2 This will allow each to be manage via a browser connection
* in router#2 disable DHCP. This forces #1 to be the manager of the entire network and it will handout all IP addresses
Personally, I use the MAC addresses of my devices to enable router#1 to use Address Reservation of IP address for all devices attached to #1 (ie I map the devices to the range 1.2-> 1.10)

Then set the DHCP range in #1 to 1.100-1.50
These will be used for all devices attached (wired or wifi) to #2

All systems can then use the firewall to allow or deny access for one or both halves of the network. EG: I permit access for 1-10 and 255 while denying 100-254​ALL system must allow the top-end address 255 as that is the broadcast address that is used to hand out the DHCP data.

Your symptom sounds like the DHCP reply is not reaching the device. Set it back to AUTO, connect
and then get the config again with ipconfig /all. If you see 169.x.x.x, that's a DHCP failure

I'm considering the upgrade above. The problem is all the reviews on both coolers were made with different cpus at different overclocking settings. I even tried to narrow the comparisons to a common denominator, like the intel stock cooler, which is sometimes present in most reviews, but even then, different cpus were used, making the info not that reliable. After some reading, I understood that the H60 is more silent and, obviously, occupies much less space, win-win situation. But regarding the performance, the info is rather cloudy.

Does anyone know anything on the subject?

Personally I have played with H60's and Hyper212's and they both offer very similar performance. I would not count that as a worth upgrade except if you want a more silent system because the Hyper212 is already such an excellent air cooler and the H60 is kinda a low end liquid cooler.

Based on my experience, the same clock on the same chip result in the H60 (The only time I tested something like this was on a Phenom II X6 1100T at 4.0ghz) being a tad bit more silent, but the overclocking headroom remains the same for the most part (Within margin of error).

If you really want to move to Liquid cooling or upgrade for better clocks and a more silent system. Either an H80 style cooler or H100i (Or a likes AIO Liquid cooler) would be the best solution to go from a Hyper212.

With that budget and 500 watts, you should not be too limited in your purchases. One thing you need to check is if your Power Supply has a set of 6 pin connectors or 8 pin connectors because sometimes on the pre-bought machines they do not have too many.

Here is what I would recommend if you have at least 2 6 Pins available:

R9 280 175
R9 270X 140

Those would both be excellent cards with the 280 being the best and the 270X being right below it in terms of performance. Both would be a huge step up from an HD 5450.

Forgive me for not knowing the proper terms, but am newer to the Wifi game - have only had it since February.

Our Gateway Laptop has always recognized our Wifi signal until a week ago. Now whenever it goes to sleep or is shut off it does not recognize that we have internet. Instead of the 5 bar icon showing; it has a red x. The only way I can get it to connect is to reboot. I have done a system refresh and also tried to update the driver (Realtek RTL8188CE) but it says I have the most up-to-date version.

This is extremely frustrating! Does anyone have any ideas?

A:Wifi Capability being turned off

"Troubleshoot problems" (right click the network icon) can fix the majority of issues without needing a reboot. It will turn off the adapter and re-initialize the drivers.

On portable devices the wireless adapter can be manually turned off for most devices. It is usually a Fn key that is used to turn wireless off.
Wireless can be disabled and enabled, within the list of network connections (Control Panel > Network and Internet > Network Connections).
I know it is frustrating and I don't have a proper solution for you. Especially when you say you have updated your drivers. But the above may help in keeping you from having to completely restart your machine.

One thought does come to mind though. That is checking to see if the wireless is set to turn off when the PC goes in sleep mode. Keeping wireless active could keep it from bugging out.

Control Panel > Hardware and Sound > Power Options > Change Plan Settings
Change advanced power settings
Wireless Adapter settings > Power Savings Mode > Setting:
There is a choice between (Performance, Low, Med, and Max)
My desktop never sleeps and wireless is set to performance. So I have no experience with the setting, I just know it is there.

Try these, I own these specific fans and they are pretty quiet even under load.

They look good, and they are pretty quiet even though I have 6 running on my radiator.

What th and I also start my apprenticeship in October which means I ll finally be earning a steady income I know I m definitely going to upgrade by the end of the year but I have a What to upgrade first? few questions first but first let me show you my current rig CPU AMD Phenom ii X T GHz MOBO Asus M A L microATX GPU AMD Radeon HD PSU Colors-IT W RAM Corsair Vengeance GB MHz Right so the issues I m facing here is whether I should do it all in one go and save up or do it gradually and if I do either I just want a second opinion on compatibility So I was planning on either upgrading to CPU Intel i - K GHz MOBO Gigabyte Z -HD GPU Nvidia GTX GeForce PSU Corsair CX W So I could either by the CPU MOBO and PSU together and transfer my old stuff for a few months or I could get the GPU and use that with my existing rig for a few months My questions are Would the GTX work with my current motherboard amp power supply What offers the biggest jump in gaming performance Thanks guys it s would be a great help The upgrade should cost me about in total I m not sure how much I ll get for my th and if I do whether I want to burn through it all right away so I d rather do it in or so chunks which conveniently it splits up into for CPU PSU amp MOBO and then for GPU nbsp

A:What to upgrade first?

The GPU offers biggest jump in gaming performance, but it recommends a 600W PSU. Considering you have an old Athlon 6-core CPU that chews power, and an old no-name PSU, I wouldn't risk it.
