Comment 46 for bug 710738

Hrm, I'm still having a bit of difficulty working out exactly why this patch fixes your particular issue. There are some strange and subtle interactions going on with the rfkill stuff, so while I believe it's possible this patch fixes your issue I still can't quite work out why.

So just to be sure that this patch is _really_ fixing your problem, I've got one more request. The bug was originally reported against a fairly old kernel, so I'd like for you to test the most recent natty kernel to verify that your wifi still doesn't work there. If it doesn't we can be sure that this patch really is what fixed your problem and not some other update in the interim.

The following commands should replace the kernel I built with the latest:

  sudo apt-get update
  sudo apt-get install --reinstall linux-image-2.6.38.8-generic

Thanks!
