I have an iBook G4 with an Airport Extreme card.

I am having serious issues whereby my signal drops when other wireless access points are in range when I'm at home (whoever uses the one that's causing the problem doesn't have it on all the time). Their access point uses channel 1 and mine uses channel 12, so there should be no interference, however

I was wondering if it was at all possible to tell the Airport card in my iBook to only look for networks on a certain channel.

Is that possible?
