** Description changed:
The iwl3945 driver in Intrepid doesn't appear to see !US wireless
channels, even on a UK laptop. My home network is on channel 13 and
completely open, but Intrepid couldn't find it until I forced it back to
channel 11. Hardy on the same hardware found and used the wireless on
channel 13 just fine.
