Hey there i got a secondhand gpd win and it was freshly wiped and reinstalled. I ran into problems with the wifi being seen but unable to connect... i tried all the driver packs 213mb and the wifi fix but i just double clicked them so that did not work.
1. What you have to do first is right click on the exe's / installers of the driver pack (213mb) and run as administrator.
then reboot to be safe
2. Then run the "wifi Us" fix as admin
3. It is really important to run/open/install things as administrator
It silly if there is one user but windoze is silly
Hope this helps somesome
