Stops Working If copying files and a DHCP request is sent

If I am copying files and the My Book World Edition II requests an IP update from the DHCP server, even though it will always get the same address, as I set my DHCP server to always give it the same address.

Immediately upon DHCP request the My Book World Edition II will crash.

If I give the My Book World Edition II static settings the problem does not happen.
