This will take some explaining. I live in a remote area in Arizona on solar power. I have satellite internet service and recently got an Airport Extreme base station and card for my 15" G4 Powerbook. It works superbly, with one exception: Quite often when I put the Powerbook to sleep and wake it up with the Airport on, it won't connect. I can't get web service or email; the little side lights on the base station don't flash, and the Airport icon at the top of the screen is gone. To connect again I either have to reboot or run the Airport setup assistant. Does anyone have any ideas as to what might be wrong? Thanks for any input.
