I have a brand new Optiplex 3020 by Dell that I went through and put XP pro sp3 on, the software we use still has XP requirements :\. Anyway, I had it all working before when it was a box with W7 on it. Now it cannot connect to the internet at all. I had to install drivers for the ethernet adapter to be recognized. I tried installing multiple drivers, most came in pairs with the prefixes of LOM or 3020 or 3011. However, it keeps telling me that a network cable is unplugged.
According to this sheet:
The computer has a realtek RTL8151GD adapter. I know I haven't tried every driver out there so throw some at me if you believe that's the issue.
I've tried using a different cables that for sure work and nothing is helping. I went through and ran "netsh reset winsock catalog", rebooted several times, and changed the network speed manually from the auto -> 1Gb -> 100Mb -> 10Mb all half+full duplex.
In this realtek diagnostic utility it says that 3-6 are mismatched:
I have no idea what this means, but I thought it could be useful.
Lastly, I understand that I could probably go back to Windows 7 and get it working. But I really need this to work on XP without a VM.
Thank you in advance.
