I just upgraded from 10.04 to 10.10 and then 11.04 and am experiencing this problem. Wireless was dropping out every couple minutes between rmmod/modprobe and these were showing up in dmesg:

lspci gives this as my wireless controller:
03:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300
Annoyed because I specifically did not upgrade to 10.10 to avoid this bug and thought it was fixed. Only it isn't.
