If they issue is fixed with Karmic, great. Mark the bug Fix Released.

If the issue remains, next have the try the following.

"Can you please try installing the following package. It contains an
updated compat wireless stack which may help.

linux-backports-modules-wireless-karmic-generic

If the issue still remains even after this, I'd encourage you to also
try installing the latest compat-wireless stack from upstream -
http://wireless.kernel.org/en/users/Download . This will allow us to
escalate this issue to the upstream developers. Please let us know your
results. Thanks."
**********
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? Can you try
with the latest Karmic 9.10 release of Ubuntu? ISO CD images are
available from http://cdimage.ubuntu.com/releases/ .

If the issue remains, could you run the following command from a
Terminal (Applications->Accessories->Terminal) while running Karmic. It
will automatically gather and attach updated debug information to this
report.
