It is only working, if only these are built in the firmware:
hostapd-common wpad-mini, nothing other like that. If not, it will not work.
There were some changes. So this is how it works with
Minimal steps needed to get WPS running:
/etc/config/wireless it is important in the
wifi-ifaceonly in the 2.4 GHZ.
option wps_pushbutton '1'
But you can do it with
LUCI as well.
opkg update opkg remove wpad-mini if you remove it, it will not work opkg install wpad hostapd-utils reboot && exit wait about 2 minutes hostapd_cli -i wlan1 wps_pbc
reboot && exit regenerate the wifi interface rm -f /etc/config/wireless wifi config iw reg get iw dev
Do what it says above. Then on router on the bottom right there is the WPS button. Click for like 3 seconds or more and it will work.
config wifi-iface 'default_radio1' option device 'radio1' option network 'lan' option mode 'ap' option ssid 'your-ssid' option key 'your-secret' option encryption 'psk2+ccmp' option wps_pushbutton '1'
