David, 802.11b/g channels are only 5 Megahertz wide. The center frequency of channel 1 is 2.412 GHz and channel 2's center frequency is 5 MHz up at 2.417 GHz. However, the energy in each channel is spread across 22 Megahertz and that is what causes the overlap. The common rule of thumb is to use only channels 1,6, and 11 as those channels do not overlap at all.

And if they do, which one overlap with which others?
