Tooway Surfbeam 2 and TP-Link WR840N

Hey guys, happy to be here.

I need some suggestions about the connection of my TP-Link WR840N and the Surfbeam2.

At the moment i connect through the WAN Port of the TP, but i'm just wondering if i could improve the speed if i use it as an access point.

Unfortunatly i couldn't get it working.

Our Surfbeam2 is working with the following specs.
