Okay, here's the situation. In the living room, there's an AirPort Extreme (latest gen) in the living room. The Extreme is connected to the cable modem. My 2011 iMac is connected to the Extreme outside via Ethernet so I can get the fastest speeds possible. I would like to set up a Time Capsule in my room that has the iMac, so I can use that to not only back up the iMac, but also to connect some legacy equipment via Ethernet in my own room. Now, supposing that all other wired connections to the TC are off, would I see similar speeds when the iMac is connected via Ethernet to the TC which is connected via Ethernet to the Extreme compared to when the iMac was connected via Ethernet to the Extreme?
