I am using the Deco X20 3-pack, 1 is connected to the modem and the other 2 are connected via ethernet backhaul through a tp-link switch connected to the main unit The Deco X20 frequently loses intern

Deco X20 is frequently disconneciting. I have the 3-pack and this issue occurs with all units (slave and main units). I have upgraded to the latest firmware and have even tried switching the deco unit
