Maybe Canonical should consider not releasing new version so frequently.

Thanks zob, I will look into this approach.
My solution was just to put 'sudo iwconfig wlan0 power off' into /etc/rc.local.
That's how I try to do most of my work-arounds.

for some iwconfig selections.

The problem is that the change that seems to have introduced this

OK, have done some more testing - things are more complicated than I
thought. Unfortunately, my hopes that the upstream kernels has fixed my

I've tested the following kernels:

@DavidM:
Can you also test the 2.6.33 mainline kernel? Lucid is based on 2.6.32,
so it would help to know which kernel the fix went in.
