Hostapd_cli wps_pbc fails!

The command returns OK when I change the "opkg remove wpad-mini" from the official documentation to "opkg-remove wpad-basic", so it now reads:

  • Add option wps_pushbutton '1 ' to a config wifi-iface section that is configured for WPA2-PSK in /etc/config/wireless
  • opkg update
  • opkg remove wpad-basic
  • opkg install wpad hostapd-utils
  • reboot

$ hostapd_cli -i wlan1 wps_pbc
OK
$ hostapd_cli -i wlan1 wps_get_status
PBC Status: Active
Last WPS result: None

I hold the WPS button on the device for 3 secs. It starts searching but never joins the router. I tried wlan0 too but same result.

That's a pitty, I had the same device working for many years using LEDE.
