I have a Gateway G1100 router with coax input. I want to replace it with a router with ethernet input.
There is a wired ethernet port at the same jack where the coax comes out, but it is not live:

At the ONT, there appear to be several twisted pairs of wires (I have already had Verizon switch the ONT from coax to ethernet. The yellow ethernet plug in the picture is the new router plugged into the ONT, but I want to move the router upstairs where the port is located):

Is it possible to activate that ethernet port? How difficult is it? Or should I just call verizon for a house call? I would like to switch to ethernet because I am told that the ONT only delivers internet over coax at a max speed of 100 mbps.
Thanks in advance!
