When I install OpenWrt 22.03.0-rc5 on a Raspberry Pi CM4 board with an Intel(R) Wi-Fi 6 AX200 adapter, and go to the wireless overview in the LuCI web interface to edit the Device Configuration, the channel width drop-down list does not include 160MHz as one of the options when AX is selected as the mode.
However, if I select AC from the Mode drop-down list, I do get 160MHz as an option in the Width drop-down list. I believe 160MHz should be available for AX as well.
I also tried OpenWrt 21.02.3, and it has 160MHz width available for both AX and AC modes as expected.
I am not sure of this is a bug, so I posted it here.
