I have the same modem and have had no problem using the ethernet port.
The USB port will never be connected to anything in my house since USB
is not a good choice for network related uses.

Get a working network card or perhaps get working software.

Perhaps your system isn't configured to load the ethernet driver or to
configure it with dhcp, or you have a firewall loading at boot that
doesn't allow through dhcp.  It really should be very easy to get
working (just forget the thing has a usb port and you should be fine).

You can also check if your dhcp client is working.  pump tends to work
well for me, while dhcpcd has some problems and dhclient is just
useless.
