I did not test this patch, but I was having wifi trouble that wmiconfig
-i eth0 --power maxperf seems to have fixed.

I don't *think* these were association problems though -- at least I
didn't see that in the log.

What was happening for me is that I got a lease and could do dns lookups
but could not ping the gateway or any other host -- there would be one
ping attempt that did not return. If I left it run long enough, there
would eventually be a few successful ones, but we're talking like 5+
minutes for that to happen. Often times despite not being able to ping
out I could ping the FR from another machine on the local network.

This is with eth0 being the only interface other than lo up, and with a
route table identical to the working route table on my laptop on the
same network. 

Anyway, with maxperf, it's working fine now. This is on a Debian system
using andy-tracking.
