@ Kanoon: First of all go to the device manager
I have just downloaded the Broadcom driver. Problem is Windows 10 does not detect the actual driver in Device Manager. What can I do?
I also had to try it several times. I deinstalled the Network Adapter and after a restart it was listed with a warning sign in Unknown or Other devices. Right klick, install driver and select the folder where you unzipped Sopi´s driver files.
