WPS on OpenWRT -- Enabling Wi-Fi Protected Setup on OpenWRT

## WPS on OpenWRT
##  This script enables Wi-Fi Protected Setup on OpenWRT.

#Install the full wpad package
opkg update
opkg remove wpad-mini
opkg install wpad hostapd-utils

#Enable WPS on the Wifi network interface.
# Notes:
#  * The network interface should be configured to support WPA2-PSK
#  * This script assumes the last interface is the one used for WPS, hence using @wifi-iface[-1]
#  * You can view all the wireless interfaces by issuing the following command and getting the index of the correct one
#       uci show wireless
uci set wireless.@wifi-iface[-1].wps_pushbutton=1

#The following are all optional
uci set wireless.@wifi-iface[-1].wps_device_name="OpenWRT AP"
uci set wireless.@wifi-iface[-1].wps_manufacturer="openwrt.org"

hostapd_cli -p /var/run/hostapd-phy0 wps_pbc

@NovaViper First restart the radio device or reboot, that should fix it. I had the same issue

What do you think about adding this line?
opkg remove wpad-basic
I have OpenWrt 19.07 @ TP-Link Archer C7 v2 and wpad-mini is not installed there, but wpad-basic is present.

I also have OpenWRT 19.07 and I cannot make it work.

 OpenWrt 19.07.5, r11257-5090152ae3

root@OpenWrt:~# hostapd_cli -p /var/run/hostapd-phy0 wps_pbc
Failed to connect to hostapd - wpa_ctrl_open: No such file or directory
root@OpenWrt:~# 
root@OpenWrt:~# hostapd_cli -p /var/run/hostapd wps_pbc
Selected interface 'wlan0'
UNKNOWN COMMAND
root@OpenWrt:~# 

What could I do?
Did anyone manage to make it work with 19.07?

If you have the wpad-mini or wpad-basic package installed, uninstall them and install only hostapd-utils, I think it helped me then.
