    So I just bought a new iMac today and unfortunately I can't connect to the internet via my comcast cable modem using ethernet cables. For whatever reason the mac is not pulling up an ip adress, I went through all the shinanigans with comcast over the phone trying to connect through PPPoE and messing with a bunch of ethernet settings but nothing worked. They scheduled a tech guy to come over Saturday but I really don't want to wait that long.

    I'm not tech savvy but if any one could please help me out I'd appreciate it.

    Don't use PPPoe, use the DCHP or DHCP or whatever it's called and it should fill in the info.

    PPPoE is usually what the Comcast router uses to communicate back to the node. You use DHCP on your PC. Unfortunately the techs usually are not familiar with a Mac.
