In my neighbourhood, I see about 10 access-points being active. About 40% on channel 1, 20 % percent on channel 6 and 40 % on channel 11. So I take channel 4 and 13 for my two access-points. I thinks thats the best I can do.
In general, performance is very good, so I think most of my neighbours are not the kind of heavy users.
What I like to know is the "network load" of an idle access-point and/or laptop. I assume there are some regular "pings" to show that you are alive, but I was not able to find more detail about that.
Anyone knows?
