The ipw2200 is the one that actually works and stays at 54 Mbps,
although it was also way down last night, but I think that was due to a
new wifi net appearing on the same channel. It was bitching about noise.

I'll give it a go - good idea. I suspect that the reception isn't too
good anyway, since even today during the day it didn't seem to like the
signal strength and the noise, when the other network wasn't up.
