Just finished installing 10.6.2 through software update. Upon reboot, the airport card is not picking up any signals anymore. I turned airport off and then back on again but no luck. It just doesn't see any networks at all, usually it picks up 4 or 5 in the area. Oddly enough, after installing 10.6.2, the wireless card doesn't work in Windows 7 w/ bootcamp anymore either. Both worked fine before the update, I just can't see any reason why Windows 7 would be affected by the OS X update. My other Windows computer connects fine to my network so it shouldn't be a router problem. Anyone else seen this issue after updating?
