I really don't know what all I need for something I'm looking at doing. I currently have an airport express but really don't have a need for wifi since my only computer is an iMac. I am looking at getting a new blu-ray player that has an ethernet jack and no wifi. So I am wanting to split my internet connection via wire to my iMac, my Apple TV, and the Blu-Ray player. It's easy to do that wirelessly, but since I cannot choose that, please tell me exactly what I need to get to make this setup work. Of course I know I will be running some wires, but what hardware do I need to split my connection? Thanks for the help.
