I have a MacBook Pro with an Apple Airport Express WiFi adapter. The machine keeps dropping off the wireless network, for no reason... and it doesn't reconnect. I'm using WPA2, open SSID, no WDS, no MAC filtering. I didn't have any problems like with with my 12" Powerbook G4. Yes there has been a new Airport Express firmware update in the past day or two, but the problems with the MacBook Pro existed before that and continue to exist. In fact they might even be worse now. Are others experiencing the same problem? As an experiment I am trying other wireless networks now to see if the problem is the Airport Express or the MacBook Pro.
