[solved] Wavlink WL-WN570HA1, Cannot set wlan0 to N

[bernigs]

on a Wavlink WL-WN570HA1, through Luci or manually editing
the /var/run/hostapd-phy0.conf to set hw_mode to N, it reverts to g.
why? is there a fix?

'hwmode=n' is not a valid setting in /etc/config/wireless or hostapd.conf. The only settings possible are 'b' (never used), 'g', and 'a'. Selection of b or g means 2 GHz operation and a is for 5 GHz. To get n speeds, combine hwmode g with an htmode. 'HT20' is almost always used on 2 GHz.

There is no need to edit hostapd.conf, it will be automatically generated in RAM from the UCI scripts /etc/config/wireless.
