HDTV, Internet and digital box? Need help.

Hello everyone. I need help, Now its 3am in the morning but i couldn't sleep, I am confused.

I recently bought a samsung 40'' HDTV with freeview. I have a 4m NTL(virgin) cable internet as well.

We have a NTL digital box(samsung). On the back of the digital box, there is a ETHERNET plug. I was think if I connected it with internet cable then i can have the virgin tv and internet same time. But seems internet doesnt work.

What can i do to make it work? Help pls. (I tried to wake up my bf to help me, but seems he get annoyed by me,:sleep:. anyway, dont think he knows more than me)

:help:thank you
