MT7621 WiFi AX routers

Luci does not support ax. You can only configure it via the command line.

Thanks for the info. How do I check via the command line to see the ax mode is running?

I think iwinfo has been patched. You can try that.
Or a wifi analyser app on any client

iwinfo gives this on my X5000R:

Does this mean the ax mode is not enabled?

Either it's not enabled, or iwinfo doesn't understand it.
Can you post your wireless config?
Remove any keys or passwords first.

Hmm... How to dump wireless configuration via command line? Not sure if I understand what you meant.

cat /etc/config/wireless

If you haven't touched the wireless config manually it's definitely not in AX mode.

config wifi-device 'radio0'
	option type 'mac80211'
	option path '1e140000.pcie/pci0000:00/0000:00:01.0/0000:02:00.0'
	option htmode 'HT20'
	option cell_density '0'

config wifi-iface 'default_radio0'
	option device 'radio0'
	option network 'lan'
	option mode 'ap'
	option ssid 'xxx'
	option encryption 'psk2'
	option key 'xxxx12345'

config wifi-device 'radio1'
	option type 'mac80211'
	option hwmode '11a'
	option path '1e140000.pcie/pci0000:00/0000:00:01.0/0000:02:00.0+1'
	option htmode 'VHT80'
	option cell_density '0'

config wifi-iface 'default_radio1'
	option device 'radio1'
	option network 'lan'
	option mode 'ap'
	option ssid 'xxx'
	option encryption 'psk2'
	option key 'xxxxx12345'
type or paste code here

How should I enable AX mode?

Change htmode from 'VHT80' to 'HE80'

Also under each radio you should set option country to your actual country code.

Did the changes in /etc/config/wireless as suggested from 'VHT80' to 'HE80'.

Run iwinfo

Not seeing ax from the output. Running the latest stable 21.02.0-rc2.
