brunofin, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Title:
  Kernel 3.0 wireless Warning bug

Status in The Linux Mint Distribution:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm using Ubuntu 11.10 64-bits.
  My hardware is an Acer Aspire 5630 notebook. Wi-fi card has 802.11 B/G support (no N), and is connected to a router running a G+N network. All other devices can connect to it with no problem, and the same notebook also have no problems in windows with the network.

  The following problem keeps occurring repeatedly:

  The notebook can connect to the wireless network in G mode and browse
  the web without any problems, but at certain point (can be after 5
  minutes of use, or also 2 hours of use, really random) it disconnects
  and can't connect to it anymore. The window to enter network password
  pops-up and then I enter the password and still it can't connect (same
  window pops-up again). It keeps going like this also for a random time
  (5min.~2hours) until it suddenly can connect again. Restarting seems
  to solve the not able to connect problem but doesn't keep it from
  occurring again. Dmesg shows the following trace:
