Maybe this is an Android issue.
Android detects there is no Internet at WLAN and switches to mobile network, until you have connected your router to a WAN...
Solution: disable mobile data in your phone, configure your router per app or admin portal and enable mobile data...
Very odd, but GL-l.iNet can not help, when the phone won't route 192.168.8.1 to the matching device, even if it is direct connected.
