Mar 15, 2010 - Windows 7 32-bit Driver Versions: Ethernet Driver (v73.20) WHQL; Network Management Tools (v73.16); SATAIDE Driver (v11.1.0.33) WHQL.

I just updated my Windows 7 Professional 64-bit to Windows 10 on a Shuttle SH55J2. Everything seemed to go normally, but after the update I have no Ethernet connection. The Windows 'troubleshooting' tells me that my cable is unplugged. Of course the cable is plugged in fine, and I've tried other cables. The cable has worked for years, and it just downloaded the whole Windows 10 update, after all.

Device manager shows a Realtek PCIe GBE Family Controller. Driver version 7.12.1218.2009 was apparently the one I first installed for Windows 7. The Windows 10 update installed driver version 9.1.401.2015. I tried both versions; neither worked.

I downloaded Windows 10 drivers directly from Realtek. I used the 'repair' option. It installed driver version 10.6.1001.2015. Backstage pass game download. That doesn't work, either. Spotify computer app download.

I installed the Realtek diagnostic product. It tells me:

Fail to perform MAC loopback action.

Fail to perform PHY Loopback action.

Realtek Audio Driver For Windows 7

Under 'Power Management' in Device Manager properties I've turned off 'Allow the computer to turn off this device to save power'. It makes no difference.

This is my main machine. It has no alternate Internet connection. I am up the creek. Why, Windows 10, did you do this to me?

Who can save this situation?
