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.

If your using a router to get wireless from a DSL connection and your laptop isn't detecting the signal it is most commonly the wireless card in the computer, hence their response. If you can access the router to check what channel it is transmitting on you may be able to change that to resolve the issue. On my cisco router it transmitted on channel 6 by default and my laptops wouldn't detect it, I changed it to transmit on channel 5 and the laptops work fine. I assume they checked if your router was compatible with your computer so I won't go into the type G wireless vs Type B or N wireless. The uninstall/install process they recommended is not hard and shouldn't hurt anything if you do that. On Vista Open Control Panel->System->Device Manager then go down the list of devices to Network Devices and select your wireless adapter and right click, from that drop menu select uninstall and close everything and reboot the computer. When the computer starts up again it will automatically detect the wireless card and reinstall the drivers from the windows system copy. Make sure the wireless device is actually manually turned on before doing any of these steps. Once the device is installed again you should be able to detect the wireless signal from the router they supplied. If not there is one more place to look in the router itself unless you are familiar with router settings I don't recommend you do these though. If you still don't detect the router signal call your supplier back and have them go through the router connections with you and when they say it's your computer you can tell them it works fine with others and you removed and installed the device as they advised and the fault is in their router.
There should have been drivers with it when you bought it. If not, here's a link:
If you install these drivers, your computer should detect the device.
You will, though, still need a modem to be able to connect to the internet.
I hope this helps, and if not, post back here,
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.

You have not mentioned having a wireless router or access point to serve as the hub on an infrastructure network. I you have a router please let me know -- the instructions for the solution changes.
The following is an article to create an ad hoc network between wireless cards without a wireless access point or a router. If you ignore the steps about connecting to the internet with a wired connection and the internet sharing instructions. This will allow your machines with wireless adapters to communicate with each other (assuming the operate on a common band). The article goes on to indicate one machine with a wired connection can act as the "router" for the other two when it is on to allow them share internet access with the wired machine (the wired machine also needs a wireless card for this to work).
