Problems Connecting MyBook 2TB for MAC to my Mac Desktop Wirelessly

It works just fine when connecting the USB directly into the desktop, but when I connect the USB into my Airport Extreme the MyBook doesn’t show up as an option when trying to setup my Time Machine to back up to the MyBook wirelessly.  How do I fix this and set it all up properly?  It’s a real eyesore to the wife to have it always plugged into the back of the desktop.  Any help would be appreciated.  Thanks.

This is not going to work

TM is not designed to work with Network drives unless you use Time Capsule

Try checking on the Apple forums to see if there are any workarounds

In the mean time you can backup the files manually when connected to the router

You can also consider getting a My Book Live
