I have a new 15" PB with the AirPort Extreme card. I also have a Netgear WGR614 Wireless router. When I set this unit up, my PB saw the router instantly and I was up and running. After a while, when I would wake from sleep or boot up, it would recognize the Netgear router but not let me connect to the internet or to my network. I would use the Airport Setup Assistant and the problem would remedy itself. Now, the PB can see the router, but can't connect, no matter how many times I run AirPort Setup Assistant.
How can I fix this problem? Is it router related? PB related?
