Not wishing to muddy the waters, but I've found that the iwlwifi driver
with a 3945 card is only reliable for scanning and associating for
my laptop (x86_64) with disable_hw_scan=1 set, this is with
2.4.24.4-64.fc8 kernel. Driver version is 1.2.26.

Previous to the recent heavy driver development, with 2.6.23.15-137.fc8
the opposite was the case. This was driver version 1.2.23.

Currently with sw scanning *every* scan returns my own 2 APs, whereas
using hw scanning I often receive "No scan results" and my 2 APs
sometimes appear in the scan output and disappear frequently. It's
equally unreliable when I can see my neighbours APs, the software scan
is reliable when signals are strong enough to register at all.

One of the Fedora common bugs advised the used of sw scanning, this is
still showing up on the common bugs list.
