Router Appears to Only Connect to Internet via Coaxial Cable, Not Ethernet
Hello,
I am an xfinity customer who has a Dual Band Wifi 802.11ac XB3 Router. Historically, I have connected my router to the internet via the coaxial cable port, without issue. I recently moved, and there is only one wall port in my new home that has a compatible port for this coaxial cable - which has worked just fine for the time being. There are, additionally, multiple wall ports that appear to accept ethernet wire connections.
For various reasons, I would like to move my router to a different location, which would entail connecting it via ethernet, or some other means than the coaxial cable. I was provided a yellow cat.5e cable when I picked up my router, and have connected this wire to a ethernet wall port that is also labelled at cat.5e. However, when I attach the ethernet to my router, nothing appears to happen: The green and orange lights next to the ethernet port on the router do not light up, and only the "Power" light on the front of the device is on.
Does anyone know what is going on here? Please let me know if there are any further details I can provide to help troubleshoot this.

It must be connected to the live Comcast feed via coax cable.

You need to connect to a coax cable for an internet connection as that is where the signal comes into your home. The ethernet jacks on the walls are not connected to xfinity's network.

What you can do is, well obviously now, leave the modem/ router in the room with the coax connection and hook that up to the modem router. I'm sure there's an ethernet jack on the wall in the same room so hook up an ethernet cable from the modem/router to the ethernet jack on the wall. Then get a router and configure it as an access point in the room you wanted to put the modem/ router in and plug that router into the ethernet jack with the ethernet cable or get a switch and do the same thing if you don't need wifi there.
