My Buffalo wireless card has worked wonderfully for nearly a full year. Now, suddenly, it detects no wireless sources at all. None at home, none at my office. Typically it detects not just my own wireless signal at each location, but several others. In fact, it normally detects several signals at virtually any location (I'm in an urban area). Now, absolutely nothing. I've uninstalled and reinstalled. Still nothing.
(Note: since the card last worked, I've had to send the computer (Thinkpad T61) for service - blown motherboard. The Buffalo card stayed home while the computer was away. I don't believe this to be a related concern: the motherboard actually blew and required service 2 consecutive times - on the computer's first return, the wireless card worked fine - until, of course, the computer blew up again (defective ac adapter, as it turned out)).

Re: Wireless card suddenly cannot detect any signals
I would suspect ya adapter.. the ONLY way to sort it is to try it in another PC see if it works.. USB devices seem to be very flimsy and we get heaps of 'em in the shop.. 9 times outa 10 it's the USB device gone weird.. substitution is the only way to isolate the problem.

Given all the circumstances, I can only guess that, for some inexplicable, apparant reason, your network card in your computer is the culprit. Try to get a friend who has the same model to swap cards with you, then you'll know for sure. The other problem could be something to do with the signal and some slight anomoly that is causing your card a problem in detecting it. A communications signal is complicated, and some wireless modems have better circuitry than others, depending on the model. But no matter how we speculate, this is just one of those Twilight Zone enigmas! Best of luck- tricky problem, for sure.
You will need to check the wireless settings of the router is there any computer connected to the router ? If yes then you can open the router set up page on that computer. Router set up page is the page where you can check all the wireless settings of the router.
Is the wireless card driver installed and working? Can the wireless card detect your Netgear Router and does it have a strong signal strength? The Wireless card needs to be configured with the Netgear Router's SSID and encryption settings before it will communicate with the Netgear Router. Let me know if you have further problems together with error messages.
Hi acording your describle, you need do
1) please check the bios first, to set wireless to enable
2) check windows right buttom bar is there a wireless icon show there and click to see any detect wireless signal, if nothing to detect
3) check or compare to other laptop wireless configuration, check any incorrect setting.
4) if all sense ok, you need check the wireless card and wireless antenna wire connection, open a samll cover at back of laptop, there is a MINI PCI slot with a wireless card, take out and clean the card pins then put back.
5) still trouble please change another wireless card (same model)
it should be fix.
hope help you to fix it, please take a rating le me know how much helped you, thanks. for any question in any time please !
Those types of devices if bent, while plugged in will stop working... Sounds like if you flex it as you plug in, it is briefly making connection. Is the device still under warranty? If so I would exchange it... One way to check whats happening on connection, right click "my computer" , go to properties, go to hardware then go device manager, then under network adapters, look for a red x. As the device is plugged watch for changes. If you see your buffalo device, and it has a red X, then I would try to re-install your drivers. If the device is not staying right after being plugged, I would suspect that may be physically broken.
can it detect the wireless signal?
did you load the drivers for wireless card in laptop?
check the device manager for any ! or ? in it those need attentio
if you can detect the wireless network then you need to set the wepkey if its enabled. if its not and you have a signal then just click on connect in the wireless network manager
if ur laptop detect full signal from ur router, click on the signal and let ur laptop connect to the signal..coz even ur laptop detect the signal,it doesnt auto connect,so u hve to connect it manually..
The connection between the laptop's internal wireless antenna and its wireless card may been disconnected. Best to take it in to a computer shop for fixing. If you want to fix it, open the PCI-E cover on the bottom of the laptop, then reconnect the antenna wire. If that doesn't work, get it serviced.
