I have a new 1TB Time Capsule that will be located near my home theater setup. We're having 1G fiber internet installed later this month and I want to be able to run Ethernet cables to all of my home theater equipment - receiver, Apple TV, Fire TV, Oppo Blu Ray and 4K TV. The Time Capsule has only 3 ports but I need 5 for my home theater. How can I expand for more ports? Can I use my previous Time Capsule somehow just for its ports and not for Time Machine backups? If so how? Or is there a cheap port expander that I can buy?
