safari5.1.8 drops off line, but airport stays connected, but window says you are not connected to internet? then a couple minutes later it reconnects. I am on an AT&T wireless.
Likely a problem with your router and/or your AT&T internet connection.
my mac G4 does not have any problem with this. suspect it is safari, airport never drop off or turn off, just safari
I'm sure you're right.
