I guess the problem is if you default it low, people will end up with slower internet for no reason. While most areas would be perfectly fine at 80mhz. Maybe routers could run their own speed test and self configure to the right bandwidth.

The Wifi Alliance may wish to provide guidance on this, at least for the residential space. Some ideas:

* have the router/AP do a speed test (at boot; regularly), and if the connect is ≤X Mbps then the wider channels won't help anything;

* do a sweep of the band (boot up; intervals), and if ≥Y% (50?) of it already in use, default to narrower channel.

Either/both of these would be done on a default "Auto-choose" setting, with allowable manual override.
