agree - look with netstumbler.
the concept of channels for wifi doesn't fit well. A "b"
card at full bandwidth occupies 3 channels. I "g" card
occupies 9. You can move the center freq by changing the
channel, but if there's interference on any of the 9
channels, you won't change the problem. It's unlikely that
interference is on only one channel anyhow. If it's
interference on only one channel, you could reduce your
bandwidth (iwconfig ?) to the minimum - one channel - (you
may be able to do this on the wap, but you certainly can do
it from the client card - iwconfig?) and then change through
all the channels one by one on the wap.
If it's interference, can you take your setup to the middle
of a field (you'll need an inverter for the wap) and see if
that fixes it.
Alternately go try your setup in someone's house that has
wifi working, exchanging cards, waps till you find the
I don't have any other suggestions though.
