I imagine this may have something to do with the intial firmware update?
After a day or two I started looking, and finally found I got the "Pending Restart" after 2 or 3 connections to the mothership in the Network Connections menu.
Give it a day or two to see if the problem still exists? I've come to see that after a FW update on an HD or Series 4 that they act weird for a day or two. I expect the same "bugginess" with the Mini.
