Hello, I've recently bought the Deco M4 to replace the Singtel modem which is in the master bedroom. I've been trying to connect two Singtel set-up box(One in master bedroom and one in living room), but only manage to connect the master bedroom. Is there anyway I could make this work? Or do I still need to connect to the singtel modem and turning the Deco 4 into an access point instead of replacing it?
