Hello thre bkitchin,
I was looking through our resources about what may be going on in this situtation and think I have an article that may help you out. It is called iTunes 10.5 and later: Troubleshooting iTunes Wi-Fi Syncing found here http://support.apple.com/kb/TS4062.
I would recommend starting at step three, as the first 2 are already taken care of, and work your way down from there.
If connectivity issues persist, quit and reopen iTunes on your computer. Then, restart your iOS device.
It's conceivable you may have to restore the iPad mini, the process is found in the article iTunes: Restoring iOS software found here: http://support.apple.com/kb/ht1414.
