Managed to sign up and download the drivers. Uploaded them here:
Let me know if you have any luck with them.
If anyone has a Baidu account could they please download the driver package for the Teclast F15 and reupload them somewhere!

I have installed the WiFi driver from the F7 downloads section on the site which seems to have fixed it. Maybe try the same and let me know if it fixes the problem…
<b>EDIT: This driver hasn’t fixed the issue – windows still can’t see the WIFI adapter intermittently </b>
