wireless card won't detect wireless networks

Q: wireless card won't detect wireless networks

Hello there. a week ago i bought a msi laptop with windows 7 premuim OS. everything about it is very good except that the adapter card is driving me nuts.
The problem is that i wont detect networks at all. i went around to places where there were wireless and still nothing. so its nothing wrong with my home network. i spent countless hours looking it up and still couldn't get an answer. i tried connecting a linksys wireless-G USB network adapter to it. it always for some reason fail to install device. but when i go to device manager and uninstall the device and plug it back in, it works fine and i can find and connect to networks. problem is, i don't really want to have to carry the adapter around with me all the time when there is a built in inside the laptop. please help me.

the adapter card is a 802.11bgn 1T1R mini card wireless adapter.

I'm hoping you guys can help...

I upgraded my mobo, cpu, ram and video card today. I kept my HDD, optical drives, and my wireless adapter (Edimax EW-7128g)

In my zeal to install my new components I had forgotten to uninstall the drivers of the edimax, which I was going to keep, and my old ATI radeon, which I was replacing.

After installing the new components, every thing started up fine, except the edimax wireless adapter would refuse to connect, or even detect any wireless networks. I uninstalled and reinstalled the drivers countless times, swapped the wireless card around in the different pci slots, but still came up with the same problem.

I noticed that when I checked the network adapters in control panel, it would keep calling the Edimax "wireless adapter (2)" or "wireless adapter (3)" depending on which pci slot I put it in. I would try renaming it to simply "wireless adapter" but it would state that an adapter by that name already exists. I'm guessing this is some holdover from being connected to the old motherboard.

In short, new mobo recognizes the card, latest drivers for windows 7 are installed, but windows keeps telling me there's an error with the drivers, and every time I try and search for wireless connections, it won't even search...it will just say "no connections available." Was this whole issue precipitated by forgetting to uninstall the drivers and the card itself before upgrading my mobo?

A:Upgraded motherboard & cpu, now wireless card won't detect networks

have you re-installed the software and chipset drivers etc - or are you hoping the Harddrive with the software on works ?

Normally you would re-install the windows software onto the new hardware - as you may get a few issues

can you do this

{Device Manager}
Post back the results in device manager
Start > control Panel {Vista set to classic view}> system > {Vista, device manager on left hand side} {XP hardware Tab, device manager button} >
windows 7
start > control panel> System and Security> Device Manager

network adaptors, click on the + > post back the devices listed there
are there any ! ? or X
post a screen shot of the device manager - network adapters

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here

i suspect the best way is to remove the wireless adapter from device manager and re-install - lets see the above

Hi all,

First off, let me preface this by saying that I am very ignorant about computers...

My laptop can't detect any wireless networks. The ethernet works fine. I have Vista Home Premium and use an Asus Laptop.

I have no idea if this relates, but every time I start my computer, an error message comes up saying that windows host processes has stopped working.

THANKS in advance-


A:Cannot detect wireless networks

Hi Caroline,

I'm not sure if there's a Vista Guru here about to reply... in case not, I thought perhaps I might be able to assist as I've troubleshooted this kind of problem before.

First off, are there any other computers in your household that are successfully using the wireless network? If so, when they connect does the wireless network show up in a list? Some networks can be configured not to broadcast the ID. In that case, you wouldn't see anything in your list.

The windows host process could very well be tied to a different issue. But in the course of troubleshooting, it may become more clear if it is involved.

I have been having some troubles with my Toshiba laptop. I have a Atheros AR5007EG wireless network adapter. Initially it started with BSOD issues. So I tried to delete and reinstall the driver for Atheros card. Now I am able to start up and connect to Internet with Ethernet cable without any BSOD issues, but I am not able to see any Ethernet connections. When I check in the Device driver, it says the Atheros card is functioning correctly. I tried to delete and let Windows reinstall drivers a couple of times, but no luck.

I have attached screen shot of the Atheros driver in device manager and the output of ipconfig /all. I would appreciate if anybody can help. My model number is L305 - S5894.


A:Cannot detect wireless networks

Hello houston2014,

Welcome to TSG!


Here is the support page for your Toshiba L305-S5894. You should bookmark this page for future reference.

Based on your screenshot, both LAN adapter and wireless network adapter should be functioning.

Let's try downloading the latest drivers for the LAN card first. They are available here. [I would have given you a direct link, but I cannot determine your operating system from the screenshot you gave].


Assuming you are running Windows Vista or later, please include a screenshot of the Network and Sharing Center in your next reply as well.

This can be opened by clicking Start > in the search bar type Network and Sharing Center and hit Enter.

On Windows 8/8.1 the search function can be launched by moving your cursor to the top-right corner of the screen.

I installed Windows 8.1 few days ago, tried to stay away from it as long as I could but it caught me off guard while I left my laptop running while I was away and it installed by itself.
Can't really say my problem was caused by W8.1 alone though, the day I installed it there were a few thunderstorms around here and my internet was dead for most of the time, when I actually checked my PC after it restarted itself it asked me to connect to the internet and showed me my wireless network but I still couldn't connect because it was out, I skipped that step and allowed it to finish and then turn off the laptop.
Next day I come back to set up whatever was left but for whatever reason I couldn't find my network on the list, figured it was still out but then checked on my phone and it was working perfectly, decided to check my other laptop and it was also working, just ignored it because my IP gives me wi-fi anyway for when the main line is out. I managed to spot my main network again couple days ago, tried to connect to it but said something about it being unavailable and dissapeared from the list again, yesterday I managed to manually connect to it and it worked, only to dissapear after a few hours. I've spotted it again a couple times afterwards but still can't connect, manually connecting isn't helping either.
I searched around a bit and tried a couple things (like disconnecting from my microsoft account, forgetting the network and then trying to manual connecting), a... Read more

I own a Gateway C-140 Tablet PC. It originally came with a Integrated Intel® 3945 802.11a/b/g wireless Mini PCI-E card. I did not have great luck dual booting into Linux with it so I purchased a replacement, the Gigabyte GN-WI01GT. The GN-WI01GT has a AR5005 GS Atheros 5th generation chipset.

This new wireless card works great in Linux now however I can not get it to work in Vista Home Premium (i know i know, but its the best OS for a tablet). Seems like I swapped my problems

I have talked with a Gigabyte tech and a Gateway tech.

The gigabyte rep suspected that the device needed to be enabled via a button on the side of the computer. On my tablet the button is using the function key and F2. I tried this and my wireless card was still unable to detect any wireless networks. He checked the driver version ( which was the latest. The device is showing up in the device manager as enabled. Vista says the device is working properly. He also informed me I should not need any separate programs to connect to a wireless network like some manufactures do.

The gateway tech was of no use and basically asked me to check the FN + F2 to enable the device told me it was a 3rd party product and gave me a gateway pay by minute tech line.

Since the new card is functioning in Linux perfectly fine I find it hard to believe that it is something as simple as enabling the wireless using FN + F2 since you would think I would be require to do it in Linux as well before it worked.

A:New Wireless Card, Unable to view Wireless Networks

I came up with a semi solution and a semi diagnosis for this problem. I put BOTH cards in at once putting an antenna on each. I noticed that when I booted into windows that the wireless light showed it was still disabled and in fact it was disabled. I used the FN+F2 key to enable wireless and *POOF* both cards work in vista now.

So my guess is there was sort of hardware check that was disabling power to my wireless or something.

I have three laptops in the house, all running off a d-link di-614+ router, using 128-bit WEP. I'm generally computer savvy, and all was running well until I shut down my computer, which runs Windows XP Home. When I turned it back on in the morning, it was unable to connect to the wireless network. When I went to 'view available wireless networks', none showed in the list, and both the 'advanced' and the 'connect' connect buttons were greyed out, leaving me only with cancel. I have no way of getting in and manually inputting settings or anything to get it to connect back to the network. The strange thing is, the other two laptops in the house can connect to the router just fine using WAN, so I know it's not a problem with the router. I am utterly baffled with this. I am using the Compaq Multiport WLAN 802.11b network card. I also tried using another wireless card I had laying around, something by the name of Proxim Orinoco, but I experience the same trouble. I am utterly baffled. When I go into the configuration utility of my compaq wireless card, it kept searching for "Agere Systems" and there was no way to change that. So I went back into my router and changed the SSID to Agere Systems, and I was able to connect. The Wireless Connection displays that it is connected with good signal strength. However, the View Available Wireless Networks window still displayed no network name at all, all buttons were greyed out, and I wasuna... Read more

Hey everyone, just installed Windows 7 7100 a couple days ago (first time using 7), and although my ethernet connection works flawlessly, my wireless card cannot detect any networks (won't show any available, and can't connect manually either). It is installed, recognized, and the drivers are updated (by Windows). It is a D-Link DWA-552 N adapter. My router is an Apple Airport Extreme. I don't think it has anything to do with placement because I can connect to my wireless network with my laptop which is right beside my PC.

It might be the card, so I did a little searching around and it seems at least one other person got it working with 7 (although an earlier version) (Dlink DWA-552 under Windows 7 - 64-bit - Vista Forums).

Anyway I appreciated any input you guys have, thanks.

A:7100 - Can't detect any wireless networks

I have had good luck going to the DLink website and downloading the latest Vista drivers, then run the install process in Vista compatibility mode. I have found some W7 default drivers are a bit lacking.

a few days ago my laptop had no internet access even though it was connected to my home wireless network. I tried messing around with it and disabled the connection. suddenly, all the wireless networks in the list disappeared, even after enabling again.

Other than disabling the connection in network and sharing center I did not do anything else. the physical switch of the wireless adaptor is on.

under "manage wireless networks" I tried adding connections but it still does not show in the system tray.

I googled and found someone saying to start a service called WLAN autoconfig, but it is already started.

turning the modem and router on/off does not help either.

I know the router is not the problem because other devices at home can still access wireless. also usually I can see my neighbours' wireless but now the network list is completely empty.

I'm using an Asus laptop with windows 7, my wireless adaptor is called Atheros AR9285 wireless network adaptor. i've attached some screenshots.

I had problems connecting to my WiFi Network these past few days. From time to time, my laptop can't detect my home wireless network at all even though other devices can detect and connect it as easily. I usually had to restart my modem and laptop or simply wait for it to pick up the WiFi connection.

Today, when the WiFi connection was shown as limited on my laptop when all other devices had a normal connection, I tried disabling then enabling again the Wireless Network Connection(?) on the Network Connections window in the Control Panel. I disabled it. But, when I tried enabling it again, the icon didn't show any change; and when I refreshed, the wireless network connection icon disappeared altogether.

I tried setting-up a new connection in hopes of locating the Wireless Network but the option of manually connecting to a wireless connection itself was gone (or anything relating to it really).

With a bit of info from googling, I checked Network Adapters on the Device Manager panel and the Wireless Adapter wasn't there (even after opting to Show Hidden Devices).

So, should I assume that this is a hardware problem? Or is there some setting that I should configure?

I'm a complete layman when it comes to computers but I'd honestly like to save money by figuring this out myself so I'm hoping it's only some setting I neglected to check given my lack of knowledge. So, may I get your advice on it?

Thank you for your response!

Hi guys~ this is my first post, I just joined the club!

Thanks in advance for all the help you can provide.

I've been having pbs with my wireless recently. It worked fine at home until I went to visit some friends in England and couldn't detect their own network in their house (I had used it in the past so Windows should've detected it automatically).

I opened the DELL Wireless Utility, which I didn't even know existed, and it could detect their network as well as their neighbours! I tried to disable Windows and let DELL configure my wireless, tried to add, connect to network etc, but nada. I re-enabled the Windows utility and now that I'm back home it's doing the same... It won't detect any networks! (DELL utility still does by the way)

What I did:

- I restarted Wireless Zero configuration: No change.
- I disabled Windows Firewall (I thought it might help?): No change either.
- I tried to update the driver: apparently it's working fine.
- I did the simplest (most stupid?) thing... switched the Wireless button off and on and off and on again....: It's working but still no network.
- I tried to set up a new wireless network with the wizard but since my Wireless is work
- ESET Smart Security says I've no viruses.
- Malwarebytes says I've no malwares.

Everything looks OK...but I'm still not getting connected with wireless and have to use a cable plugged directly into the internet box.

For the past few weeks I have been having problems with my HP laptop.

For starters my laptop will not restart. I try to restart it and it shuts down, but won't reboot all of the way. It gets stuck on the black screen you get just before the HP sceens comes up. So I have to press the power button ( after which I do, I get a loud POP sound before the computer shuts off ) and then turn it on again myself.
Also, if my computer goes in to sleep mode due to inactivity, it will not wake up. I have to press the power button to turn it off, and then start it up again.

After this happens, my laptop cannot detect any networks. I have to unplug the charger, and then I have to take out the battery and put it back in before it detects networks.

I took it to best buy ( where I bought the computer and have a warranty at ) and they did a diagnostic test and determined that I had several viruses causing the problems. After paying 200 bucks they ''fixed'' my computer and I brought it home, only to have the same exact problems I was having before.

This computer isn't even a year old... What could be wrong?

First off, my name is Stephen and know a little about computers, but not a whole lot.

Now for the issue, I have a Dell Latitude D610. It is a company computer and just got it back from the IT dept. because I had to have the monitor portion of the laptop replaced. I believe he replaced the on board card as well because I have noticed that I cannot see any networks now. I do have a verizon wireless card that I use while I am out and about, but I would like to be able to connect to my network at home and at work for a faster connection while I am at those places. And I would take it back to the IT dept., but I have to submit a ticket and it can take sometimes a week for them to get me in.

There is no wireless switch and the device is enabled when I look at it through the device manager. Any idea how I can get this to detect networks without me having to go back through my IT dept.?

Thank you in advance

Hi there,

However, from my laptop, I cannot detect any wireless networks. I just came back from China, and the computer detected wireless networks there, but now doesn't recognize any at home. Usually there are 3-4 networks in the area.

My wireless switch is ON. I checked device manager, and 1394 Net Adapter #2 was disabled; I enabled it. Everything else (including Wireless 2200BG Network Connection) seems to be enabled and working fine.

A:Solved: Can't Detect Wireless Networks

Read other 13 answers

Hey guys,

I did a clean install of Windows 7 on my desktop last night upgrading from Vista. The install went smoothly and all was working until I tried to install my wireless adapter (TrendNET TEW-424UB) and discovered that although the driver installed, it could not detect any wireless networks. My first thought was that the adapter just wasn't compatible with 7 so I went out and bought a DLink DWA-125 only to discover I'm having the same problem. So I googled this problem and discovered that a great number of people are also having trouble with Windows 7. After browsing through the forums I've been unable to find a general fix for all of this, I found something about the WLAN config utility that 7 has, I disabled it and tried uninstalling/installing the adapter drivers with no luck. And then the same thing when re-enabled it again.

*Edit* I forgot to mention, the network works perfectly without a problem. As I type this there are two other computers connected via wireless to it and when the computer had Vista installed it worked without a problem.

So my question is, has this problem been solved yet or am I stuck without an internet connection?

Thanks for your time.

I am having a problem with my wireless network cards. I have a Netgear WNDA3100 v1 wireless card that was working for a little while. The problem was that when I turn on my computer, the card could not find any wireless networks. I would do the "troubleshoot problems" and it would fix it most of the time. (i have to do 1 or more of these: take out the card, reinstall drivers, reboot, change usb port to get it working) But now that won't work. I tried it on another computer and it works fine. I also got another wireless card, Belkin F7D2101 v1, that does the exact same thing.

Drivers are all recent as of today, windows 7 64bit ult and kaspersky internet security 2009 are up-to-date. no virus, malware, etc. according to kis and mbam.

Hello, My laptop won't pick up any wireless networks at all - I'm having what seems like a few different problems: 1.  Because the laptop won't pick up any wireless networks, I can't of course connect to the internet without using my ethernet cable. 2.  When I try to turn my adapter on using the F12 key, all it does is toggle airplane mode - which isn't going to help me connect to the internet. 3.  When I go to 'Network' under PC Settings, I can toggle airplane mode but the bluetooth is greyed out and can't be toggled and it doesn't even give me an option to turn back on my wifi adapter. 4.  When I went into the Network and Sharing Center to enable the adapter that way under 'Change Adapter Settings', I couldn't even see the adapter listed there.  All it showed was Ethernet and Hamachi because I use LogMeIn Hamachi on my computer. By this point, I was like "Oh, great - the adapter might somehow not even be there even though it was last night," (I was online wirelessly the night before) so I went into the device manager and then expanded Network Adapters I only saw the same two Ethernet and LogMeIn adapters. 5.  So next, I tried downloading the adapter - but the problem is, I have no idea what kind my laptop is supposed to have.  Going to the download drivers section in the support area of the hp website, I found many options and none of them seemed to work.  I also tried redownloading the Wireless Butt...

Hello dginther, Welcome to the HP Forums! I understand wireless is not working properly. If the issue just began occurring, I would perform a system restore. I want you to bring the computer back to the earliest restore point possible, in an attempt to dodge whatever caused the issue. Here is a document on how to perform a System Restore: System Restore Next, please try the steps in this HP document: Troubleshooting Your Wireless Network and Internet Connection (Windows 8) These steps should be enough to resolve the issue. If not, you can try a manual reinstall of the driver: 1. Go into Device Manager, then Network adapters.2. Right-click on the wireless driver, and select "Uninstall".3. Restart the computer. This will force the driver to reinstall itself. Please let me know the results of your troubleshooting. Thanks! Mario

I use my wireless network at home, perfectly fine. Sometimes I'll go hardwired if I'm doing a lot of uploading.

Recently went on a trip and stayed in 3 different hotels. Hotel 1, I was able to connect my laptop to their wireless, no problem. When I got to the second hotel, my laptop would not detect the wireless. So I pulled out my other laptop and volia... wireless. So its clearly an issue with my first laptop. I've since gotten back home and attempted to connect to my own wireless... and bam! nothing.

I do NOT have a wireless switch on my laptop anywhere, so its not a case of accidently disabling the wireless. For my HP to disable, I have to go to the wireless network connection and right click to disable or enable. Its currently enabled. The adaper says its working correctly.

When I run ipconfig my IP address (when wired) is

When I check my event logs I do see this message: Dhcp-Client Event ID: 1002

I recently installed a Belkin N300 on my backroom PC which has Vista Ult OS. The purpose was to connect to the WiFi router/modem of my main PC which has Windows7.

I installed it exactly as instructed by the manufacturer using the disc that came with the adapter. That is, run the disc first and install the adpater when prompted. It said it installed successfully, and Device manager said it was running properly, but in practice it could not detect any networks. Network discovery was turned on, and no yellow warning triangles.

After about an hour of fruitless attemtps to fix the problem, I did a bare bones installation of Vista and installed the adapter on it and it worked perfectly. And it continued to work even after all the various 3rd party software and Windows updates were installed. However, if I now uninstalled/reinstalled it, it would no longer detect networks, even though Device Manager said it was running properly.

I was curious to see if the problem was an incompatibility issue with Vista, so I installed the Belkin adapter on my main PC which already had Windows7 fully loaded. And then tried to connect with a wireless router/modem on the Vista PC. And I got exactly the same result ... everything green lights, but in practice it could not detect my WiFi modem on Vista, or any other networks in the vicinity.

So I repeated the process of installing the adapter on a bare bones installation of Win7, and as on Vista, it now worked perfectly. And continued to work wh... Read more

A:Wireless adapter failure to detect networks.

Hi, I know it is an old posting, but I've just spent many hours with similar problems of the nic says ok and drivers all ok, but no connection.
I found this information to share.

1) On web, some people report disabling or having to remove anti virus and/or firewalls. Zone Alarm and Kapersky are both mentioned as being disabled/removed to solve similar issues. I had ZA and disabling didn't solve my connection problem.

2) This did solve for me. Boot into safe mode, in device manager disabled the wireless. Then in device manager rescanned hardware, which reloaded the wireless. After reboot normally, the wireless worked! I experienced/confirmed this with both a Rosewill pci nic and a Edimax usb wireless adapter.

Hope this helps.

fantastic specs - everything is nice and responsive, except that i can't connect my wireless at uni. the tech guy had a look at it and he can't figure it out either.
we did everything, including shutting down (eventually deleting) the AV because of its firewall. we set up the network exactly as everyone else does (and it works for everyone else).

the computer keeps suggesting that we check the router (but the router works). i can get net through RJ45 no worries but... i want my wireless to work.

Could be many things. wee need more information to diax. it could be as simple as the modem is shut off. Yes there is a key combo to turn it on. Or it could be a driver (check in device manager). It could be a confiuration error.

Hi guys, got a bit of a problem with a Toshiba laptop. All of a sudden it can no longer detect any Wireless networks in range. I know my router is working, as I have a second laptop that is not having issues, and all my wired PCs are fine.

I've tried repairing the connection, and everything appears to be working correctly in Device Manager, but I just can't detect a single wireless network, when I should be able to see 5+ in my house.

Any advice you guys have would be great.

Are you SURE the wireless is enabled? My Toshiba laptop has a small switch on the side that will disable/enable the wireless. Some may have a function key sequence that does the same thing.

Welcome to SF,

Your O/S profile says Vista, what is the O/S of the computer in question?
Please try a System Restore, restore it to a point where you were able to connect.

Here's a Vista guide.
Here's Windows 7 guide.

If the System Restore didn't help at all, please download the Wi-Fi driver from your computer's manufacturer's site.

An update will be appreciated.

I am running Windows 7 64bit retail on an Intel DX58SO2 extreme mobo with i7960 CPU and Corsair SATA3 SSD hard drive, with 12GB KIngston DDR3 1300 RAM.

The mobo comes with a module that connects to an internal USB header which runs Bluetooth and a WiFi 802.11bgn wireless adapter.

I had used Bluetooth without problems for some time, but just recently decided to install the WiFi adapter for the first time. It said it had installed successfully, and showed up on Device Manager as working properly. However, it could not detect networks, and in particular, the WiFi external modem/router on my other PC.

After exhausting all possible solutions, I decided to load a bare bones installation of Windows 7 and it installed and ran perfectly in this environment. And it continued to run OK after all my various programs were loaded.

However, as a test, I uninstalled it from the fully loaded OS, and then successfully reinstalled it. But once again, it could not detect networks despite Device Manager saying it was working correctly.

So it seems the only way to get it to work is to load it on Windows before any other programs or updates are added; and never uninstall/reinstall.

I also had exactly the same experience on my other PC which runs Vista Ultimate OEM. I was using a Belkin N 300 adapter on this OS. It could only be loaded and run successfully on a bare bones installation, but once running, was OK even when all other programs were added.

Hey all!

my dog accidently jumped on my table and spilt tea all over my keyboard. Thank god it still works even though the keyboard doesnt really work properly which i am not too bothered about as i am going to get it fixed next week

Main problem is ever since the incident, my wireless adaptor does work but howwever it doesnt detect any wireless networks. I am using windows 7 and i can load up the wireless manager where i can select my wire less network.. but for some reason all i can isee it Dial-up and VPN and above saying "connections are available" even though no wireless networks are showing

normally i can see about 6 in my neighbour hood but all i can see is a dial up one that i setup a few months ago

my wireless adapter is Atheros AR9284 Wireless network adapter


A:Spilt Tea - Cant detect wireless networks n keyboard problems!

How do you know he accidentally did it?

Seriously, if it is a laptop computer and there is a chance the spill ran under the keyboard, I would disconnect the power and take the battery out until it is completely dry. This took almost two weeks for my sons laptop.

If it's a desktop, just use another keyboard until this one dries.

My organization utilizes quite a few Thinkpad Yoga S1s (20C0 and 20DK), all of them seem to have issues with the wireless adapters, they will intermittently stop detecting any wireless networks. We have noticed that this seems to happen most often when moving the laptop either between APs or to different wifi networks, and to get it to work again we either have to disable then re-enable the wireless AC adapter's driver or reboot, sometimes needing to do both. We have tried more recent drivers and it doesn't seem to have much effect, has anyone else seen this issue and do you have a resolution? Thanks

A:Thinkpad Yoga S1 wont detect wireless networks

You don't mention operating system?  It is hard to diagnose without seeing it, but try this:
Under device manager/network adapters, right-click the wireless card and select properties.  On the power management tab, uncheck the option that allows the computer to turn the device off to save power.

I apologize if this has been posted before, I tried searching but couldn't find it.

About 3 weeks ago, my Dell Inspiron 600m running Windows XP Pro (32 bit) suddenly became unable to detect wireless networks in the area. I have a standard integrated wireless card (Intel PRO/Wireless 2200BG) and all signs show that it is working properly, only it won't detect wireless networks that are clearly available.

Also, when I go into Wireless Network Connection Properties and hit "Configure" next to my wireless card, I get a pop-up notification stating "Adapter state not found in registry." I don't remember seeing this message in the past, but I can't really say when it started happening.

I have tried various networks in various locations, it doesn't detect anything. I have an updated driver (w29n51.sys & Netw2c32.dll) , I tried using system restore to roll back to before the problem began, no luck.

Any ideas would be greatly appreciated.

I have tried everything. Updated drivers, downgraded drivers, tried drivers from another manufacturer, uninstalled and let it auto install the "correct" drivers. I changed my power settings to max performance, messed with the signal configuration and most recently, completely reset windows.

Before reseting windows, it would detect wireless networks about half of the time but then would disconnect from them every 5 minutes or so, making it very difficult to use. Now, after reseting windows, it has not been able to detect any wireless networks at all.

This issue has occurred on ALL wifi networks, including my mother's in Virginia, my university and my apartment in San Diego. It also does not occur on any other device including my old computer (this one) and my phone. All other devices have unbroken and healthy signals on the same wifi.

Could it be a faulty network adapter? The computer is refurb.

Hello all. I came across this website and forum through searching for this problem. I've come across similar problems but they all either end with the person taking their computer to a shop or it goes unsolved.

Here is the issue:
My computer (Dell Vostro 1500 with Windows XP) will not detect the wireless network we have here at home. The wireless card is an Intel Pro Wireless 3945ABG. The laptop has a light that shows if WiFi is on or not. Whenever I turn on the laptop, the light is usually on but not detecting any wireless network (either ours or someone else's).

-This started happening about three weeks ago. There was no damage to the computer. I reformatted the laptop and reinstalled all the drivers but the problem persisted.
-Turns out one of our cats had thrown up on the router we had at the time so I figured that was the problem and waited until we got another one.
-The new one came yesterday and everything was working fine. A couple hours later the problem resurfaced.

I rolled back the driver thinking maybe that was the issue but apparently it wasn't. I tried uninstalling the wireless card and reinstalling. The only thing that accomplished was deleting the profile I had on there. I've tried the simple repair option but that hasn't worked.

I know the router is broadcasting a signal because everyone else in the house is getting the connection.
