Realtek Ethernet Controller not displaying or usable.

My computer has stopped showing the Realtek Ethernet Controller in device manager. It isn't showing under the "Other Devices" Tab and doesn't show when I select "Show Hidden Devices" that people have mentioned before. I have tried a lot of different fixes but can't seem to get it working (See below). Now it hasn't been plugged in for 2 to 3 months but it was working before. It's the ethernet port built on to the motherboard. Does anyone know any other steps I can take?

Motherboard: B360M-A

Specific issue: No Ethernet Controller displaying in Device Manager (Checked "Other Devices" tab and "Show Hidden Devices") but in "Add or Remove Programs" the Realtek Ethernet Controller is there. Installing driver only gets the "The Realtek Network Controller was not found if Deep Sleep Mode is enabled Please Plug the cable" error. I can plug in a simple d-link USB Wi-fi adapter and it gives me internet.

Fixes tried:

• Updating the Driver - Get Error saying "The Realtek Network Controller was not found if Deep Sleep Mode is enabled Please Plug the cable"
  
• Flashing Bios to latest version
  
• Updating CPU drivers from website
  
• Tried "Net winsock" and "netcfg -d"
  
• Manually disabling in bios and re-enabling it.
  
• Uninstalling the driver from "Add or Remove Programs" and Installing Controller from Realtek website - Same result as updating driver.
  
• Network Reset built into windows.
  
• Booting into Safe Mode to see if I can do anything there - No results, same issues.
  
• Tried going into "Services" and putting WWAN AutoConfig, WLAN AutoConfig, and Wired AutoConfig to Automatic from Manual.
  
• Plugging in USB Wi-fi adapter to update windows and any other app.

To isolate the case, we would suggest that you use other "Realtek Ethernet", and see if it does the same thing.
