By using one in the middle you're getting interference from those using the channels either side, so if you're using channel 3 then channels 1 and 6 are interfering with it (as well as 2, 4, 5 and 7). You can actually get more interference by selecting a middle channel than using the same one as someone else.
Correct. 1, 6 and 11 are known as the clean channels. But I thought N had more channels, and therefore more 'clean' ones...
