Tested my new wifi autochannel algorithm on 2.4 GHz in a noisy office.  Most of the routers in the room were on channels 1, 6, or 11, but there were at least a couple of outliers on every single channel (this is New York after all).

Anyway, my algorithm picked channel 2.  Conventional wisdom is that this is exactly wrong, because it is a partial overlap with channel 1.  Sadly, I double checked the math, and it checks out.  It may have actually made the right decision for a very complex situation, assuming my algorithm makes sense at all.

I'm pretty sure this is how it will feel when the machines take over.

Meanwhile, I guess I should just do a speedtest on every single channel and do this objectively.
