I have a similar issue, with an intel utlimate-N chipset on a lenovo T410 in an enterprise WPA setup with multiple routers. I installed linux-backports-modules-cw-3.6-precise-generic to get the latest drivers. This seems to in general improve the connection dropping I was experiencing, but still is a bit quirky. For example, network manager sometimes gets confused, and no longer show a network name even though the network is connected. Also, the connection still occaisonally hangs, though I can't be certain this is a driver issue -- could be on the router end.
