So here's my problem, which I saw a similar problem but that solution won't work in my case.
Okay my Gateway laptop is equipped with a Intel(R) PRO/Wireless 2200BG Network Connection wireless card & at one point I was able to get select wireless networks but now I get nothing. Yet another laptop, a Dell if that matters, will get the signal. I tried turning off the firewall on both Windows XP and my McAfee Internet Security programs. No dice, still nothing. Now I'm in a truckstop right now and it's an open network but I get no signal. Any help with this would be great.
