Oneiric also once in a while (minutes/hours, depending on how much
traffic I make) disconnects the Wifi (WPA2) connection and 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).

I use the latest official launched kernel on Oneiric (3.0.0-16-generic) and all 
updates up-to-date. Should I open a new bug report?
These issues with ath9k last since forever  :(
