The WiFi "channels" on most B, G & N systems (2.4GHz band) overlap. This means that if you are on channel 1 & your neighbor is on channel 3, then
they are interfering with each other & both need to be moved to channel numbers further apart.
To truly separate the bands so they don't interfere, you must use channels 1, 3 & 11 (in the US). These channels do not overlap & interfere with each
There are monitor apps (like NetStumbler) which are free to download to ensure you are selecting the right channel to inter-operate with adjacent
Also, in Australia, Europe, New Zealand and Japan, the band allocated to 2.4GHz is bigger than in the US (in Japan there are four non-overlapping
Another rule of thumb, if you go higher in frequency, you can get a faster throughput BUT lower frequencies travel further! If you are less than 30
feet from your AP with no intervening obstacles, go for the highest frequency (highest channel) you can.
Also, be aware that wireless 'phone handsets also use the 2.4GHz band & many 'channel hop' to get the best signal & this heavily stuffs with WiFi.
Keep them away (physically distant) from Your WiFi if possible.
