I just got home from a restaurant where I tried to use their wifi and got this exact problem. I couldn't even restore the image successfully there. I got home and went straight to restoring the image again, and it worked. In hindsight, I wish I had just tried to boot first, just to check.
I'm concerned that there is a defect when interacting with certain types of wifi bands/modes/?? If that is the case, the problem will never be resolved in a specific location until the bug is fixed.
