Hello, I recently moved into a new house and had the internet set up by Cox. I would like to extend wired internet to the upstairs rooms but don't want to feed Ethernet cable throughout the house. The modem that Cox installed is plugged into a main feed auxiliary port in the downstairs living room, I am trying to figure out if it is possible to setup a MoCA network with how Cox has my internet set up. The main feed auxiliary port is the only on the ground floor and i'm wondering if it's even possible to have the feed come out through that port, pass through the modem, then transferred to a MoCA adapter and back into the same aux port. Any help would be greatly appreciated.
