With a little more troubleshooting I've discovered that it only happens when connecting to a 5ghz Wireless-N network. I assume then that my PAN is also transmitting at 5ghz when that happens so my other devices (all of them G cards) can't see the 5ghz network.
Just tested with work laptop that has 3945agn card and it sees it.
Question answered...problem solved.
