[Solved] Only 20Mhz channels on AR9565 wifi adapter

[unxed]

How to enable 40Mhz channels? My router supports it, is flashed with lastest openwrt and has 40Mhz enabled. Other clients work fine on 40Mhz. Kernel is 4.15.

Btw, connection is still at 20Mhz

Sorry for that, has to enable "force 40mhz channels" in openwrt settings to make 40mhz work. Btw, this setting violates the standard and also does not bring any significant speed inprovement in my environment, so I disabled it back.
