Hi, I recently purchased a new Apple TV (2010) to set up at my girlfriends house. The set up is very simple: she has a cable modem that plugs into an Airport Express, the Apple TV connects to the Airport wirelessly. I set up the Apple TV no problems at all, everything worked great, I connected to the network, entered in my netflix account info and everything was up and running. I ran into a problem when I opened up my Macbook Pro. It shows full connectivity to the wireless network but I have no internet access. I get a message that says, "another device on your network is using your computer's IP address. It gives a weird IP address that isn't even close to the IP addresses that the Airport Express should give out (169.254.111.112). The Airport is set up to give IP addresses in the 10.0.1.X range. After I get my Macbook Pro to access the internet the Apple TV stops working so I can't use both at the same time. Any advice on how to fix this? I am guessing I will have to connect to the network manually instead of by DCHP? It is very frustrating, I had no problems whatsoever with the Roku player I bought her and had no clue I'd have so many problems with the Apple TV.
