I have a dell wich has an internal wireless networking card. It's worked fine for the last year and a half, but now seems not to work. In the apartment complex I'm in there are four or five that I'm in range of, and the ethernet port is working just fine. The stupid thing just can't find any networks, but I know they're there (my roommate is using our wireless router as I type this). It was workign fine, and quite out on me the other night. I've ran virus-scan, but I have no idea what else to do to try and fix this. Any suggestions?
