Wireless connection not working

[florin]

This is an old bug and I was waiting to see if Oneiric inherits it. When downloading at high speed the wifi connection is randomly not working. It is shown to be working, but it's not. I have to manually reconnect to make it work. Sometimes it is not reconnecting to the wifi router and I have to reset the router.

I am using the ath9k driver for my Toshiba Satellite C650 laptop (Intel i3) with Atheros wifi.

I ran the ubuntu-bug when wifi was not working, hoping that it would catch some data needed to debug this very old problem (I always had it since I switched to Ubuntu (at least since Ubuntu 10.10)).

It's very easy to reproduce it, I only need to download something with 2 to 4+ MB/s on wifi and it's just a matter of time until the bug occurs.
