[sanette <1171257@xxxxxxxxxxxxxxxxxx>]

I confirm that this bug (same as #779159)
happens sytematically on my laptop running ubuntu 12.04 LTS (with up-to-date upgrades)
and that it seems to be solved by reverting to older firmware iwlwifi-4965-ucode-228.57.2.23
as suggested by https://bugs.launchpad.net/ubuntu/+source/linux/+bug/779159/comments/11

  Same issue description as for bug #779159, wlan works but with many interruptions.
  Running command dmesg | grep "SW error" shows a large occurence of the following log trace :
  iwlwifi 0000:25:00.0: Microcode SW error detected.  Restarting 0x2000000.
