i recently just built my desktop and installed windows. i wish to connect my desktop directly to my internet modem. when i connect my Ethernet cable to the back of my desktop and to my modem nothing happens, i am not prompted to join any network. i tired the same thing with my laptop and it worked perfectly and i got internet access. how to i get the modem to work with my desktop like it did with my laptop? i don't think i have any CD for the modem as it is abit old. if anyone could please go through the steps of how to get my modem to work with my desktop i would be very grateful. thanks
