I decided to take the plunge and install win 10 on one of my machines. Used windows update to install build 10074 from windows 7. Everything seems to have worked fine except my network adapter (onboard Realtek thing) isn't being detected. Figured this might be a driver thing so I installed various versions of the realtek drivers both win 7 and win 8 ones and these seem to install fine but then cannot detect the card. The installer gives an error that the card may be in 'Deep Sleep mode'. Once installed the Device 'REaltek PCIe GBE Family Controller' appears in device manager with no issues or conflicts, but nothing is in the Network Connections window when I go through Network and Sharing centre. I have tried booting to the trouble shooting menu and selecting load unsigned drivers but this has not worked. Microsoft Sidewinder Drivers For Windows 10.
I rolled back to Win 7 and the card came back and all connectivity was restored. Re-installed win10 and back to the same issue. Driver Macbook Air Windows 10. Any thought/ideas? I had the same issue with the network adapters not appearing when I upgraded from 8.1 to 10.
