I have a Belkin wireless router model 3 f5d7234-4 v4 and I have an HP hard drive Windows XP. I have cable internet. The modem on the cable internet is an Arris model TM602G/CT. I tried to following the easy instructions from Belkin. I left the cable model connected the same except I took the ethernet cord from the back of the cable modem and put it in the yellow modem port on the Belkin. I then took another ethernet cord and placed one end in the back of the cable modem and the other end in a port on the belkin. (also, I plugged the router into an outlet) By doing this I can't access the internet. On the Belkin the modem, router, wired and wireless lights up but not the internet. What am I doing wrong? I can usually follow directions but I am not very computer literate.
