|I'm not familiar with that modem/router. It's possible that you have the wrong type of Ethernet cable. There are strait through cables and cross over cables. Most routers will work with either, but some (particularly the combo devices ISPs give out) won't.|
A new cable is a quick, cheap way to find out.
Before you do that though, connect through the hub (aka, the working way), then check what your computer's IP address, gateway, and subnet are.
Switch to connecting directly to the router, and check the IP, gateway, and subnet again. Did anything change?
