[Bug 874678] Re: Wireless connection not working

 

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.

Title:
  Wireless connection not working

Status in “network-manager” package in Ubuntu:
  New

Bug description:
  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.
