Time Capsule slow on Ethernet I'm having issues with my just-purchased Time Capsule (2 TB). I have it in my room connected wirelessy to an existing network. I think this means I'm not taking full advantage of 802.11n, right? I'm doing the intial backup of some files. It is taking 20+ hours to transfer 40GB of data.

I expected the wireless transfer to be slow, but not so much! So I tried to connect to the Time Capsule from my MacBok Pro via Ethernet, but the connection speed didn't change, and this left me wondering: shouldn't be the connection via Ethernet be way faster? What is the proper way to configure this?
If you connected the Ethernet cable while the backup was running, it is probably still utilizing the wireless interface. It can not re-route an established connection in the middle of the backup.

Start by cancelling the backup. Then do one of the following:


Disable the Wi-Fi interface on the computer; OR...
Open Network in System Preferences; click on the cog button below the list of network interfaces; click on "Set Service Order"; drag the services so that Ethernet is on top of the list; click OK and Apply.


Now, restart the backup.
