I have a laptop that stopped recognizing wireless networks. I know that there are networks in range b/c I have another computer connected to the network right beside this machine. The owner informed me that no changes have been made to the settings to their knowledge before this problem arose. I checked drivers and they seem to be installed and working properly. To my knowledge the wireless adapter is not "turned off" in any way. Could this be a faulty adapter or is there another possible solution to this problem?

i think that is an inherent weakness of wireless. Itmay work 90-95% of the time, but the last 5-10% drives you nutty/ Why does everyone seem to have computer except me?!

Look in the Properties of the wireless adapter. Make sure to UNCHECK "Allow the computer to turn off this device to save power" Rich Gu

could also try to uninstall/reinstall your wireless drivers on your computer to see if that corrects any possible errors. As said above... wireless rocks 90% of the time... lol. TK.

Will try. Thanks for the help!

If your notebook has XP SP2 Imbedded, htere is a hotfix for it-it's a known issue. Microsoft, however won't give it to you unless you call their tech support phone line. jerks.
