Wireless card suddenly cannot detect any signals

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)).

Please help!

    my laptop quit "hearing" the network. It detects all the wireless in the area and sends packets out but received none back, even from the home router it has seen for years. I have downloaded the driver and installed again, no affect. Wireless is an INTEL PRO/WIRELESS 2200BG network connection 9.0.4.37.

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.

HP 550 - Unable to detect just a particular wireless network


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.

Cannot detect any wireless connections


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.

Acer notebook wireless just connects when near to the modem...


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.
