Solved Realtek Network Driver Conflict After 10 Update

Users have reported that their Realtek PCIe Family Controller (Ethernet) randomly stopped working after they upgraded to Windows 10. There are still no answers from Microsoft or Realtek as to why would this happen, and this situation happens 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 the Realtek Driver

Option One: Reset TCP/IP

1. On your keyboard, press theWindows logo key , typecmd , right-clickCommand Prompt from the results, and selectRun as administrator .

When prompted with the following notification, hitYes to continue.

2. Type in the following command:

netsh int ip reset c:\resetlog.txt

Make sure that you have made no typo and hitEnter .

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 to the stage where it still works.

Option Two: Change Settings in Network Adapter Properties

1. PressWindows key andX at the same time, then chooseDevice Manager .
   
2. Locate and click the arrow to expand categoryNetwork adapters .

3) Then right-click Realtek PCIe GBE Family Controller option and choose Properties .

4. Go toAdvanced tab, then chooseSpeed & Duplex option on the left side of the pane.

5. On theValue bar, change the default Auto Negotiation to 100 Mbps Full Duplex or some other options accordingly. We chose100 Mbps Full Duplex here, but yours could be different.

6. Now on the left side of the pane, chooseEnergy Efficient Ethernet option, then change the Value toDisabled . After the changes, hitOK to save.

7. Still, in theProperties window, this time, let’s go toPower Management tab. Un-tick the box forAllow the computer to turn off this device to save power . Then hitOK to save and exit.

Option Three: Reinstall or Rollback Realtek Adapter Driver

1. PressWindows key andX at the same time, then chooseDevice Manager .
   
2. Locate and click the arrow to expand the categoryNetwork adapters .

3) Then right-click clickRealtek PCIe GBE Family Controller option and then chooseUninstall .

HitOK 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 can 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 the driver, it is suggested that you roll it back to the stage where it was working well.

Option Four: Update the Realtek Driver

The steps above may help you resolve the issue, but if they don’t, you can try to update the Realtek driver. If you don’t have time, patience, or computer skills to update the driver manually, you can do it automatically with Driver Easy .
