Now after upgrade to Ubuntu 11.10 when resume from suspend, wifi fails
to reconnect saying waiting for authentication. When I use older kernel,
2.4.38 instead of the new 3.0.0, it still works OK. If using ethernet,
after wake from suspend it always works OK.
More details on this bug are here
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/880648
and here
https://bugzilla.redhat.com/show_bug.cgi?id=7374
Tried new Ubuntu kernel 3.1-rc10 did not help. Did not try an alternate
kernel with Fedora 15.
The common failure messages seen with Ubuntu and Fedora is this:
<info> (wlan0): device state change: need-auth -> failed (reason
'no-secrets') [60 120 7]
Oct 24 01:20:00 hplt NetworkManager[1016]: <warn> Activation (wlan0)
failed for access point (dbnet)
After this occurs, no further attempt to authenticate wifi occur and a
red X appears over the wifi icon. I must then use ethernet (or reboot).

So we need to bisect between 2.4.38 and 3.0.0? :) I'm running ubuntu
11.10 on a home laptop so I'll give this a try as well when I can if I can
put up with unity for that long.

Hi,
Any results on this home laptop test yet? (Running kde-ubuntu here :) ).

I've bisected the problem and narrowed the bug to changeset 73b78a2272
(http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=73b78a22720087d2d384bdd49e9c25500ba73edd).
Here's a patch, that applies against 3.2-rc5, that fixed the error for me:

this is not right, you stop the bt coex for non-combo device.
maybe you system has issue with BT, we seen this happen on some cases.
try the following module parameter and see if help
$sudo modprobe iwlagn bt_coex_active=0
Thanks

bt_coex_active=0 fixed this issue, thanks Wey

Unfortunately the latest fedora 16 kernel, 3.1.6-1.fc16.x86_64, renders
this fix
ineffective and again cannot resume wifi after a sleep and must reboot.
Therefore must stay with older kernels for this to work and for wifi to
resume
after sleep:
3.1.5-6.fc16 is still OK with bt_coex_active=0
3.1.5-2.fc16 is also still OK with this fix.

The kernel 3.1.6-1.fc16.x86_64 now uses wireless driver called iwlwifi and
not iwlagn. I was not setting the parameter correctly. When I do this
modprobe iwlwifi bt_coex_active=0
the workaround is still OK and wireless reconnects after sleep.
