Thank you for the time spent to troubleshoot the issue.
I have already carefully checked the bios settings and Windows drivers.
It did not appear in the device manager but everything else works fine.
I suppose as you said, that the module is faulty, i should be able to get a laptop with LTE capability and check if the LTE appears here and determine if the card in indeed faulty.
I know the tablet is not designed for Win10, but if one have a bit of knowledge as i have, one can manage to get i work with good performances, even if being almost 7 years old.
One need to fiddle a bit with the drivers versions, which is not always an easy thing for everybody, i acknowledge that.
The tablet feel responsive and works very well for normal daily usage as internet surfing, video playback and light loads.
The only thing i would like is to have the possibility to change the fan curve settings, but no complaints aside that.
Most importantly, you answered to my main concern about the stock configuration of the tablet.
As i said, i thought the seller got the version without the LTE module and installed it afterward.
This was my main concern, if i would try to buy a LTE replacement, the replacement won't work.
I will keep you updated about.
Many many thanks, great support from Fujitsu.
