How does that work then. Being on different channels?
By using non-overlapping channels like 1,6 and 11 the client device picks the strongest signal and hops over when the one it's on gets too weak.
Keeping them separated gives the best performance.
Automatic channel selection often makes dumb decisions, like using channel 4 and bleeding over the useful channels.
