Can’t get to sign-in page with GL-iNet travel router at hotel

I just purchased a Gl-inet travel router (GR-AR300M) so I can set up a camera to watch my dog in my hotel room, just for an hour here and there while I work out, etc.

Frustratingly, I’m getting stuck - after setting up the router in repeater mode, I get as far as choosing the hotel connection. But then I can never enter my room number and password because when I open the browser it doesn’t take me to the sign-in page from the hotel. There’s no internet connection yet so the page never appears.

Thanks so much for any help you can provide!!

Please disable the ADGuard and the VPN Client first if the router requires to login the portal.

Or may try the method 2, login success in the phone and clone the phone MAC to the router.
