Re: getting the most out of bb50 or more via wifi

There are 3 non-overlapping 20 MHz channels 1, 6, 11
With 40MHz 2.4, there are no non-conflicting channels (why when using 40 MHz you can't select a channel) - yes over simplified

Or detects devices that can't do 40 MHz it will drop back to 20 MHz as wel.

Some devices are more conservative than others on when to drop back, is what I should have said instead of "not all devices implment it properly"

No actually that's incorrect. And besides the point since with a clean 130 Mbps connection, which can do 50 - 60 Mbps of throughput, you can easily handle a 50 Mbps internet connection. Bonding another channel when you're getting 5 Mbps isn't going to help that much.

The Wi-Fi Alliance pointed out that the second equation in part 10.15.3.2 shown below adds an important behavior. It essentially says that if either the primary or secondary channel of a 20/40 router or AP is the same as either the primary or secondary channel of a 20/40 neighbor AP or the operating channel of a 20 MHz router or AP, then 40 MHz operation is permitted. The reason for this is that since the two APs are operating on the same frequencies, each one can understand the other's transmissions and can coordinate transmissions properly.
