Running Ubuntu Lucid fully upgraded, had this same problem; wireless would drop, I'd get the two "balls" only one green, system would search for a network forever...killing wireless would not help...sometimes stopping and starting the network-manager service would fix it, but not always. I've since had to move to a custom kernel for an unrelated standby / recovery issue...so I'm afraid I won't be able to contribute much here (given I'm running a non-standard build now) however, I just removed network-manager and installed wicd...so far, so good! I'll keep you posted. Hope to see this fixed in an upgrade down the road.
