So I'd just use the "common" upper channels 149-161 at either 40 or 80 width, depending on whether I wanted stability or maximum throughput. Truthfully, I just about always use 40 MHz width on 5 GHz because my WiFi devices don't need much speed.
But wifi uses at least 20 Mhz of spectrum. So a wifi radio using 20 Mhz centered on Channel 1 will have signal going up to 2422 Mhz, well into Channel 3. A wifi radio centered on Channel 6 (2437 Mhz) will range down to 2426 Mhz, below Channel 4, and as high as 2448 Mhz, past Channel 8. And that assumes only 20 Mhz channel sizes. 40 Mhz is also
The default driver restricts to 20MHz transmission. The mimo_bw_cap will remove this restriction and allow 40MHz to be activated. Please use this command: wl mimo_bw_cap 1. Note: This command must be set in the down position prior to the chanspec command. View solution in original post. 3 Likes. Reply.

difference between 20mhz and 40mhz wifi
