Transfer AirPort Time Capsule to External Drive

Then, that would explain the 22 hours.

A Thunderbolt to Ethernet Adapter would be a handy item to have in your desk drawer for testing and file transfers, etc.

I just want to make sure I understand the current condition of the TC. Are you saying that it will not power-up so that it could be accessible from the network ... OR that it can, but it may not be configured properly so that it can be accessed?

Second, is your goal to transfer Time Machine backups from the TC to the Seagate NAS or just other files?

Hopefully, your Mac is not connecting to the network using wireless. Is it connecting that way?

The file transfer should take about 8-10 hours if the Mac is connected using Ethernet. It might take 2-3 times longer, on average, using wireless.

It's really water under the bridge at this point since the file transfer has already begun.

My suggestion was to make use of the Thunderbolt to Ethernet adapter in the future. You can order this online from any number of sources, some of which offer next day delivery if you have more file transfers coming up.

You might not be aware that the USB port on the Time Capsule is old and slow USB 2.0....and....that the processor inside the Time Capsule runs at only about half the speed of a USB 2.0 port on a computer.....so the file transfer would probably take even longer using USB than wireless.

If transfer speed is important, stop the current transfer, order the Thunderbolt to Ethernet adapter and run the transfer when the adapter arrives.
