Under Windows:

First, download and install:

https://dl.radxa.com/rockpix/drivers/windows/Broadcom%20802.11ac%20WDI%20SDIO%20Adapter%202017-10-19-1.596.33.0.cab

Then, download https://dl.radxa.com/rockpix/drivers/windows/AP6254.zip
and
extract and copy all files to C:\Windows\System32\drivers and reboot.

Tnx for you advise.

I installed the corresponding drivers but no success yet.
When checking the device mgr i don´t see a Wifi Network Device. Also no Bluetooth device.
I something wrong in my BIOS setup?

tnx for your support
Andi

Additional info: After installing ubuntu there is also no wifi device visible. Only bluetooth. So i think it is a BIOS issue.
