Just had another instance of freezing. Trying to connect wifi to use PC auto save. When looking for the router automatically and then again doing manual setup at the point of connection to router. Everytime it freezes. Looks like many others have the same issue. My only thought is Fuji has released the camera knowing it is not complete. The firmware release on Nov 8 may fix some of these issues. I was shocked to learn I can not tether the XT2 yet. We had this ability in the XT1 but not the XT2 until Nov 8th. I hope the other issues like PC auto save are fixed soon.
On the up side, I have not had other freezing while shooting since using 2 Lexar UHSii cards of the same size and speed.
