Default Bug#578262: Intel 5300 wireless does not work on Acer TravelMate6293.

I would like to submit additional information on the reported problem
with the intel wireless card.

It seems the problem is similar to the Bug 558002:
"wifi Link 5100 not working on F12" found in Fedora and solved
recently by Stanislaw Gruszka.

See: https://bugzilla.redhat.com/show_bug.cgi?id=558002

The bug concerns Quality of Service (QoS) frames. It affects possibly
a functionality of newer intel wireless cards when connecting to APs
that do not support QoS properly.


From what I know two patches concerning this were submitted to the
kernel.org by Stanislaw Gruszka.

See: [1] patch-86913 and [2] patch-86914

[1] https://patchwork.kernel.org/patch/86913/
[2] https://patchwork.kernel.org/patch/86914/

If the patches are applied to the current Debian linux-2.6.32
kernel source (2.6.32-5) the wireless card works correctly
and the reported problem is solved.

The patches, adapted to fit current kernel-2.6 source, are attached.

I am really sorry for submitting the bug twice (also as Bug#578263).

I hope this information will help someone.

Those patches were rejected. I think the accepted versions are:
