I just got my new iMac today, but I can't get it online!! I use Adelphia Powerlink, and have used it with my G3 iMac and my 15" G4 iMac. I connected it to the modem and opened system preferences. I chose Configure -->Using DHCP. On both other computers, it configures automatically. It is not working this time. It gives me the same number for IP Address and Subnet Mask, but nothing appears under Router. So, I tried Using DHCP with manual address, and entered the IP Address listed on the old computer. Still nothing. So, I then tried to configure manually, simply copying all the information from the old computer, including what is listed under Router. Didn't really expect this to work, and it didn't. Any suggestions?
