hi clclndpunk, I just got the solution today from a fujitsu tech who knew what he was doing. So here it goes:
I did a fujitsu recovery as per their instructions (ie shutdown then when powering up pressing the F12 which went into the CMOS and followed the prompts. Make sure you recover to only the C drive so as not to override the hidden files in the D drive.) When the tablet was working fine but not allowing any microsoft updates as yet I went to the fujitsu website and found under: notebook - T series - T731 - Atheros AR938x update. (first look in your device manager network adapters to make sure you have Atheros AR938x driver. I then downloaded and saved that fujitsu update. Then double clicked it which updated. Then I rebooted. Then allowed microsoft updates and crossed my fingers and guess what. It worked. It did not lose my wireless which is why I am typing and answering you on my tablet now. Hope this helps. Lesson learned: not all fujitsu techs are the same.
