What about power line adapters? I’ve got a pair and they just sit there doing their thing, no config needed, just plug in and away you go. So long as you’re on the same electric circuit, they’ll connect over that. Mine are made by TP Link and never had a problem (not sure if Unifi make them, sorry). Best of luck to you!
