atheros ar9485 wireless network adapter. turns off

I can't restart the computer each time I lose connection and but restarting the router is clearly faster. Usually a restart either of the router, or of the ubuntu system makes it work again (until it disconnects again). 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. This bug makes a linux system totally unreliable for long automated run or for any kind of larger/faster downloads (I can never download torrents without hardware restarting my router at least once) using wifi connection. Yes, it is a very old and nasty bug, I could see it during the last Ubuntu versions.

AR9285 Wireless Network Adapter (PCI-Express) (rev 01) Sudo lspci -v -s 02:00.0 |egrep -v 'Serial Number'Ġ2:00.0 Network controller: Atheros Communications Inc. I use the latest official launched kernel on Oneiric (3.0.0-16-generic) and all updates up-to-date. 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 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 (asks for wlan key but it cannot connect no matter of the key). It might help you with tracking this if you know that it is a very old and nasty bug, I could see it during the last few Ubuntu versions.
