I want a wired internet connection to my TV upstairs in the master bedroom which I am able to do with the built in Ethernet cable in the wall. However, I can’t seem to get a internet connection by plugging my TV into the Ethernet jack. I’m assuming because the Ethernet cable in the wall has been dedicated for the WAN port on the router. I can’t seem to get a “LAN” connection through the wall. Can anyone help me solve this? Thanks.
