Just cannot set channel width to 20/40/80+80Mhz on my hAP AX2.
As soon as I set this width it keeps saying "no supported channels", regardless of which channels are selected. Any suggestions will be highly appreciated

By the way, I can not check which channels are allowed. wifiwave2 seams does not have a command listed in wiki

When selecting 160MHz I think DFS channels are required. And, there are only two options for a 160MHz bandwidth: 5170MHz - 5330MHz or 5490MHz - 5650MHz.
I have absolutely no experience with this, but I assume you should change frequency and allow DFS channel first.

And from the documentation I would leave the frequencies default (empty) and the skip-dfs-channels default (disabled):

Not sure why they don't hide the option, the chip doesn't support 160mhz at all as far I know.

Try entering the command as written in the wiki, without the quotes
/interface/wifiwave2/info country-info Ukraine

See what frequencies are supported and set the auto frequency selection.
/interface/wifiwave2/radio print detail

PS /interface/wifiwave2/info

Try entering the command as written in the wiki, without the quotes

Thank you, but no luck so far...

Checked it, there is no info menu. The wiki is inaccurate.

Tested on AC3 and AX3:
/interface/wifiwave2/info country-info doesn't work anymore since 7.7
They still did not fix it.

/interface/wifiwave2/radio print detail does show something but not the same.
