I figured this was worth forking a new thread rather than dragging out an old one.

I've now got two 802.11n (2.4GHz) APs: one upstairs in the wiring closet and one downstairs in the home theater rack. I've got them current set to automatically select their frequencies, and they seem to be consistently selecting the same frequency as each other. At different times that I check, that frequency will move around, but nonetheless it doesn't seem like the optimal answer.

The immediate neighborhood isn't what you'd call a congested WiFi environment. I can pick up maybe three or four other APs, but they're all -80dB or lower.

I suppose I could just tell my APs to occupy two specific (and different) frequencies and not worry about my neighbors. Or, is the "auto" frequency support genuinely doing the right thing and I should leave well-enough alone?
