AX86U how to lock ch.161 and 160mhz?

[willyburz]

I have found my cleanest channel is 161, but when I force 160 mhz, I can't select ch.161? What am I doing wrong? At one point it auto selected 161 and was locked 160mhz. I updated firmware, and rebooted but now I can't manually select ch 161 AND have 160 MHZ forced?

i checked mine, i cannot select control channel 161 when i force the channel bandwidth to 165MHz. I see that 161 should support 165MHz, based on this link https://en.wikipedia.org/wiki/List_of_WLAN_channels

i'm not sure about this but maybe because of the region? i'm in asia maybe that's why i cannot select it.
