[Setup] ER707-M2 gateway connected to my ISP (gigabit fiber). SG3218XP-M2 main network switch Couple EAP772 wifi access-points (powered via PoE ports on the switch) All centrally managed via an Omada

In my old setup I had 3 EAP245's which have recently been upgraded to EAP772's due to higher demands on wifi. Every once in a while we notice that it is no longer possible to connect to other devices
