Cloudflare has data of more sustained-use bandwidth that shows lower numbers: * https://radar.cloudflare.com/quality https://radar.cloudflare.com/quality 1x1 40Mhz = 287Mbps PHY ~ 143Mbps realistic ~ 100Mbps probable. Double that for 2x2 40Mhz: 200 Mbps. Certainly some connections may need more, and is the reason for >40 Mhz options, but I'm not entirely convinced one of those should be the out-of-box default. This less of a concern in 6 Ghz because there are many more channels, but this is what the story is all about: how is that frequency band going to be allocated? In US/CA all of it basically went to Wifi, and that gives folks more options, even in more densely populated areas.

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.
