>>Sorry I didn't get back to your earlier. I have not tried disconnecting wifi because it is physically not easy (the router is in the corner with all kind of junk around it and the desk is in another room). But what I thought right now is I can disconnect the cable from the router and connect it to the cable modem.

Unless it's a newer one - they typically have one port that already includes the cross-over built in but the port is labeled - if not on the equipment itself, then in the manual. Sometimes it's the port labeled "wan."
