Hello, I have 2 RE450s one on each side of the house the router is in the center, the one on the left side is in the garage, there are 3 devices close to it I can get 2 devices to connect to that extender but one device insist in connecting to the router (the router's signal is pretty low) compared to that of the RE, which is the reason why I place it there. How can I force the Envoy PV system device to connect to the closest and strongest signal? Thanks in advace. Block MAC ID at the router? I got ATT service.
