Comment 103 for bug 548992

Same here on a Thinkpad T500, tried the various fixes suggested but no improvement. Also tried various kernels, wicd, new firmware etc., and Windows connects just fine.

One thing I noticed is that the timeouts appear as soon as another machine is connected to the AP - it's fine as long as it's only this one.

I suspected networkmanager at first, but the problem seems to sit somewhere deeper.
