I think there might be an issue with the Intel 3945 driver in the kernel. I tried to downgrade wpa_supplicant to the version used in Karmic, that did not help. I also tried to uninstall Network Manager and configure manually, but still the same problem. That leaves the kernel as the most obvious thing having changed since Karmic. Hmm, it should be possible to try the old kernel ....
I see this problem after upgrading my Thinkpad T60 after upgrading from Karmic to Lucid. It often takes up to 10 min before I can get it to connect, then it disconnects after an hour. Signal strength seems to have some influence, the problem gets much worse if I move away from the router.
