you should have been supplied the correct cable in the 1st place with your modem.

1. unplug the usb cable.

2. turn off your pc.

3. turn off the power to the modem.

4. Turn on the modem and connect the ethernet cable to it and then to the pc.

turn on the pc.

check your ip address ans report back here with the 1st 2 numbers ie. 192.168.xxx.xxx or 81.4.xx.xx

if no connection unplug the ethernet cable from the back of the modem and check that none of the pins are bent.

turn off any firewalls just to rule them out.

make sure you have no connections in internlet options and set it to 'never dial a connection'
make sure nothing is ticked or entered in the LAN settings box in internet options.

thats all i can think of for now.
