This might sound stupid but I was wondering ,
I have a coex cable in each rooms , but the IT guy installed the router in the living room , how do I get a wired connection? Is it possible using the coex cable as an Ethernet cable ?
Assuming this is a modem+router combo box, you could had asked the cable guy to place it in the room of your choice with the coax out, assuming you have a diagram of how the coax cables are connected and whether already using an active booster. Still want to do this, u will have to DIY it now.
