I have a 1 GHz 15" PowerBook running 10.2.6 and connected to Comcast Broadband Cable internet via a snow AirPort Base Station. I recently backed up my information and performed a clean install of OS X. I didn't have this problem before, but now when I open the screen and the computer wakes from sleep, the internet doesn't work. I have to select the icon in the menu bar, turn off AirPort, wait a few seconds, then turn it back on. My roommate, who has a 700 MHz 12" iBook also running 10.2.6 doesn't have this problem. Is there a setting I need to change to fix this? Thanks for any help you can provide.
