The basic rule is 3 channels of separation,
Its actually channel 1, 7 or 11 on the b/g/n 2.4MHz
and if your WAP is on the default channel, maybe a neighbour's is too, and on the same channel. This will cause problems with signal and traffic.
If they are on the same channel then they will share the bandwidth
If it's the case, and it might be, then just make sure you choose a channel that's 3 removed from the neighbours' channels, or at least, the strongest ones.
Use one of the above, if someone is on 7 and someone else on 9, then choose 1. This is set on the WAP itself, or ADSL router if its combined.
PS. Had a (very) quick google for netstumbler-like tools on Linux:
http://www.kuthulu.com/iwscanner/ http://apradar.sourceforge.net/ http://wifi-radar.berlios.de/ http://www.kismetwireless.net/
A lot of these types of tools have quite a lot you will not need, just look at the "overview" or "home" screen.
