Unable to enable Ethernet connection after fresh install

Hey guys,

I just installed Windows 8.1 from disc. I am using an ASUS P8Z77VLX Motherboard for this.

I just installed all of the drivers for my motherboard but the Ethernet connection was not detected. I went into network settings to find there were now two Ethernet connections, one enabled, the other disabled. The disabled one apparently was added by my motherboard drivers. I attempt to enable it, it says its enabling, and then nothing happens. The windows says its enabled, and it isn't. It doesn't ever appear to actually change.

I ran an sfc /scannow and got no errors.

So, at that, I'm out of ideas. Any help would be greatly appreciated.

Note: I do not have a Wifi adapter on this desktop, only Motherboard Ethernet available.

Welcome to the forum!

Did you try uninstalling the adapter(s) in Device Manager then reboot and let re-install?

Yes.

Also, here is some technical data I found.
Device PCI\VEN_8086&DEV_1E3A&SUBSYS_84CA1043&REV_04\3&11583659&0&B0 was configured.

The PCI Simple Communications Controller not having a proper driver appeared to be the issue, but I installed Intel Management Engine, resolving the PCI Simple Communications issue, but the ethernet connection still does not detect a cable.

You're sure cable is good?

A search did reveal others having same problem with your motherboard.

Which Ethernet chip do you have? The Asus site shows either Intel or Realtek drivers.

I'm not sure.

I don't know how, but the issue somehow resolved itself.

Well, that's good. If it happens again it could be your cable.
