Realtek Ethernet Controller Driver Not Working After Windows 10 Upgrade [Solved]

Sophie Luo, in Driver Error Tags: Realtek



Users have reported that their Realtek PCIe Family Controller (Ethernet) randomly stops working after they upgraded to Windows 10. There is still no answers from Microsoft or Realtek as to why would this happen, and this situation happens so randomly on different occasions, so there are a lot of solutions that could be of help. 

If this is the problem you are experiencing now, please follow the instructions below to get it fixed by yourself. 

Option One: Reset TCP/IP
Option Two: Change Settings in Network Adapter Properties
Option Three: Reinstall Realtek Adapter Driver
Option Four: Update Realtek Driver 


Option One: Reset TCP/IP

1) Press Windows key and X at the same time, then choose Command Prompt (Admin)


When prompted with the following notification, hit Yes to continue. 


2) Type in the following command: 

netsh int ip reset c:\resetlog.txt 

Make sure that you have made no typo and hit Enter



This will help you reset your TCP/IP (Transmission Control Protocol/Internet Protocol). To make it easier to understand, TCP/IP is the language that your computer uses to communicate with the outside world. Reseting TCP/IP will help you revert your Internet settings back to the stage where it still works. 


Option Two:
Change Settings in Network Adapter Properties

1) Press Windows key and X at the same time, then choose Device Manager



2) Locate and click the arrow to expand category Network adapters



3) Then right click Realtek PCIe GBE Family Controller option and chose Properties


4) Go to Advanced tab, then choose Speed & Duplex option on the left side of the pane. 


5) On the Value bar, change the default Auto Negotiation to 100 Mbps Full Duplex or some other options accordingly. We choose 100 Mbps Full Duplex here, but yours could be different. 


6) Now on the left side of the pane, choose Energy Efficient Ethernet option, then change the Value to Disabled. After the changes, hit OK to save. 


7) Still, in the Properties window, this time, let’s go to Power Management tab. Un-tick the box for Allow the computer to turn off this device to save power. Then hit OK to save and exit. 



Option Three: Reinstall or Rollback Realtek Adapter Driver

1) 
Press Windows key and X at the same time, then choose Device Manager



2) Locate and click the arrow to expand category Network adapters



3) Then right click Realtek PCIe GBE Family Controller option and then choose Uninstall


Hit OK to continue. 


4) Go to the menu bar on the top and click the button for Scan for hardware changes.


5) Windows will help you automatically install the correct driver that it could find. But there is no guarantee that the new driver is going to work, since Windows has provided the not working one originally. 

If you clearly remember that your Ethernet stops working after you update to a certain version of driver, it is suggested that you roll it back to the stage where it was working well.
