Connect mesh network using Ethernet cable

[ItayAM]

I’m trying to connect 2 ASUS AiMesh routers (DSL-AC68U as mesh router and RT-AC66U B1 as node) together with a long distance Ethernet cable. Mesh network is up and working over WiFi for now. So I wired my house (with about 20m, or 65 7 feet ) with a cat7 F/FFTP cables, I terminated them both with keystone jacks, t568a on both ends. I used the keystone jacks for esthetic purposes only, small house. When connecting my pc to the jack I get a link (only receiving), but no IP. Same happens with the mesh node.

I guess I missed something out (maybe crossed/patch issue). Should I buy a cable tester and check my wiring or an I missing something more obvious? Help a newbie out
