I just moved in with someone who uses ethernet, and I'm struggling to get my macbook online. At my old place, I had a wireless router and connected via airport. When trying to connect, I could not let the DNS server setup automatically, since I would get the message that I could not connect through this self assigned IP address. So I setup the connection manually, writing in the IP, router etc info, and now it says that my ethernet IS successfully connected. PROBLEM: I still can't get online! The network preferences state that my ethernet is connected, but I can't get on Firefox, Itunes store, or anything. I'm new to Macs (been using PCs all my life) and I'm so confused. Is there some setting I need to alter to make these programs recognize that I'm now connecting through ethernet? I turned my airport off, but is there somewhere I need to make ethernet my default or something? Help would be appreciated, I'm clueless!
