Q: I "upgraded to iOs7 and ever since when I try to connect to Facetime my ipad says "Could not sign in. Please check your network connection"  I can connect with every other App. Not sure what to change?

Start with these suggestions.

Go to Settings>General>Date &Time>Set Automatically>On. Make sure that the time zone is set correctly as well. If all of that checks out, reset your router and your iPad.

Unplug your router for about 30 seconds. Plug it back in. Then reset the iPad. Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
