Just to clarify, I have already connected the cable from the tv to the modem, the ISP is not coming to my home to do this. I get a message on the tv that says "IP Auto Setting failed. Network set up complete but cannot connect to internet. Contact your ISP to use the internet to upgrade your tv software." When I call my ISP, they transfer me to the Premium Tech Support Center. The $40 charge is for 30 min of tech support over the phone so the ISP can "fix this common problem."
I'm just wondering; A) what exactly the ISP will be doing on their end, and B) if this is something I can do myself.
