Yes, it is a very old and nasty bug, I could see it during the last Ubuntu versions.
I get it once in a while (minutes/hours, depending on how much traffic I make); it disconnects the Wifi (WPA2) connection and I cannot connect back to it. Usually a restart either of the router, or of the ubuntu system makes it work again (until it disconnects again) (haven't tried disabling&enabling the adapter since Natty). I use the latest official launched kernel on Oneiric (3.0.0-16-generic) and all updates up-to-date. sudo lspci -v -s 02:00.0 |egrep -v 'Serial Number' 02:00.0 Network controller: Atheros Communications Inc.
