I'm back home from college for a bit and I'm trying to get my ibook onto my parents cable internet (cox cable). When I plug it into the modem it picks up an IPv6 address, IP address, and subnet mask, but I still doesn't connect. When I click the "assist me" button in the sys prefs to configure the connection it tells me it can't connect automatically and that I need either a DHCP client ID or a PPPoe account name and password. We weren't given any ID or account/password to use, it's supposed to just connect automatically. We never got any software to install either. My brother set up the internet and said all he ever did was plug in the modem and it worked (on an old HP desktop). What am I missing?
