Hello, I have MBP 2015 early and interesed in buying Time Capsule (2gen) for Time Machine backups. Unfortunately, I don't know how it works. My computer uses wifi and it's impossible to use any cables in my home now. I read some information and Time Capsule use AirPort. But how does it work? I will can use wifi on computer AND direct connection to time capsule in the same time? Or maybe only use AirPort to connect Time Capsule to my existing wifi network? I will be grateful for any help and suggestions. BTW. Why not USB HDD? I'ld like to "hide" backup device and make it as quiet as possible.
