I have a broadband modem, connected to a wireless router, which is also connected to my desktop, and until a few days ago, my laptop could connect to the wireless network fine. for some reason it no longer works. my laptop has vista, and the desktop has xp, and there was some fiddling around to do to make it work in the first place, and it worked fine for a couple of months, and now the laptop can't even find the wireless network. i've reset everything, rebooted everything, and I just have no idea what the problem is. Even if i have the laptop within a foot of the wireless router, it can't find the network. My cousin's laptop on XP still finds the network fine. I have no idea what to do.
