And here also. This is on a Thinkpad T60p with an Atheros AN5212. Incidentally, the AN5212 appears to be unsupported by the ath5k module, even though it claims it, meaning that I had to blacklist the Ath5k module so I could run with ath_pci to get any wireless working at all.

It looks like there is another workaround than removing/reloading the kernel-modul. The interface wifi0 is missing after resume. After configuring this interface by

ifconfig wifi0 up

networt-manager can reconnect (ya href="https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules/+bug/272300/comments/16">see comment #16 on bug #272300</a>.
