Having issues setting up mesh network for home use, Running following devices, Archer A7 as router with wifi disabled, TP-Link 5 Port Gigabit PoE Switch TL-SF1005P switch, OC200 controller for management. Tried using EAP225-Wal V2 as root AP and then wirelessly connect for mesh to EAP225-Outdoor V1. Both EAP are running version 5.0 firmware. 

Issue is after adopting the EAP225-Wall it does not locate the other EAP225-Outdoor to adopt it. The only way i can adopt the EAP225-Outdoor is if i hardwire to the switch but in the deployed environment need to have it connected wirelessly via mesh. Have even resetall devices and started over with same results so not sure if i am doing something wrong with install or issue with one of my devices compatiability 

If compatabiilty issues what devices do i need to update?
