Hello,

40 MHz bandwidth provides better performance but it overlaps 4 adjacent channels on each side, therefore, it might overlap with many other Access Points working in those channels. If that is the case, the router will switch back to 20 MHz mode automatically to reduce interference.

Hi. Thks for answer.... There are only 2 other AP.... With small signal.... Is it possible to force 40mhz anyway?!?!?!

No. It will not work unless the other APs operate in channels that don't intersect with your RUT's AP. If you have access to those APs, try manually changing the channels that they use. I recommend installing a WiFi analyser app on your phone for tests. It visually displays whether the frequencies of different APs intersect or not.
