AR300M + Wavlink AC600

I’m desperately trying to increase range for my travel router.
So I bought a dual frequency outdoor router of Wavlink that only seems to work in boost mode (1000mW) when used as AP. So basically I guess what I’m trying to do is to make it catch a far hotspot internet connection and make it share via LAN to my GL travel router. Is that possible?
Basically it’s two APs?
I’m struggling with the set-up… Sorry, for the potentially stupid question.:grimacing:
