The Beelink BT3 pro is a cute-looking miniature computer running Windows 10 Home Edition – I use them for running information displays in conjunction with Xibo (https://xibo.org.uk/), an Open Source digital Signage application.
These boxes are great…right up until when a Windows update goes wrong and they trash themselves! Reinstalling Windows on the BT3 pro requires a very specific set of drivers, and Beelink very kindly puts a set on the Mega download site…which you can’t then download (without paying or selling your soul) as they exceed the free data allowance!
To cap it all, if/when you do get hold of the drivers and reinstall them, everything works EXCEPT wifi, which will fail to start.
Here’s a few tips to save you a day or so of swearing…
- As soon as you get a Beelink BT3 pro box, use the free app Double Driver (http://www.majorgeeks.com/files/details/double_driver.html) to backup your drivers.
- Use Belarc Advisor (http://www.belarc.com/products_belarc_advisor) to take an inventory of your machine setup and – very importantly – your Windows serial number. Copy and paste the reported info into a text file and keep it safe; this *may* help with re-installation and avoid you needing to try and interface with Beelink’s dismal ‘support’ services.
- Take a copy of the file C:\Windows\System32\drivers\4345r6nvram.txt
BONUS:
Here’s a ZIPped (237MB) copy of the drivers and the wifi txt file from one of my Beelink BT3 Pro systems (Windows 10 64-bit Home) – it’s provided ‘as is’ so don’t blame me if it breaks things (although if you have a Beelink without working drivers, things could hardly be worse):

Fixing wifi on a Beelink BT3 Pro
If you need to reinstall your wifi drivers, putting C:\Windows\System32\drivers\4345r6nvram.txt back in place and restarting windows will actually make your wifi work again!!!
You’re welcome
I don't blog

Thank you. Hasn’t worked so far yet with your leads I will get there.
I actually bought mine and immediately installed Linux Mint 19 64x which worked sweet. I encountered the same issue yet I had to install a different Broadcom driver yet the same way. I had to install Win10 just because my particular app for this asset OpenCPN did not have a good AIS driver so I went back.
