Comprei um roteador do modelo ex220 ax1800 e não consigo restaurar os padrões de fábrica dele

Can anyone tell me how to configure the 5 EX220 V2 units with the requirements below? - I have a server with DHCP Server and I can assign IPs associated with the MAC Addresses of the network equipment

I bought 5 identical routers, EX220 V2, and I configured one of them as CONTROLLER and the other 4 as Client. Problem: I configured the controller with a fixed IP. 192.168.10.240/16 (class B mask), ho
