It is very peculiar to Windows 10 PCs but it is also present in other versions. Whenever this software has issues, the situation is always unpleasant. This is especially because you will not be able to carry out many internet functions. In severe cases, you won’t be able to get an internet connection at all. When it occurs, your device manager might show either error code 31 or error code 12. You would also see a yellow exclamation mark next to the Realtek PCIe GBE Family Controller.

The good news, though, is that this is not without a solution. It is quite easy to fix the issue. In this article, we have put together all you need to know about Realtek PCIe GBE Family Controller. We have also curated a list of possible solutions to the common issues associated with it. Whether you use a Windows 10, 7, or 8 PC, these solutions would work out for you.

What is the Realtek PCIe GBE Family Controller?

It is only right that we start by discussing what the Realtek PCIe GBE Family Controller is all about. It is the controller being used to operate the LAN hardware in the computer’s motherboard. It connects the CPU PCI Express of the computer to the Giga Band Ethernet (GBE). Hence, it controls all the network functions of the computer. Basically, it is responsible for letting computers run on the internet.

Whenever there is an issue with the Realtek driver, there are always two main causes. It could be due to software problems with the drivers that run the LAN. It could also be because the LAN card has worn out. Whichever one it is, we might not know for sure. One sure thing, though, is that you can fix the Realtek driver issues all by yourself.

Update the Driver

Update the Driver

This is the easiest method to use. This is because it only involves updating the Realtek driver software of the system. This problem could have occurred because the driver is outdated. So, to fix it, it is only right to attempt to update it. Start by checking if the driver is outdated or not. If you realize that it is not, then follow the steps below to update it

  • Open the Run box by pressing both the R button and the Windows button together
  • Type in ‘devmgmt.msc’ into the box that pops up. This would open the system’s device manager
  • From the list of devices that pops up, search for ‘Network Adapters’ and click on it. From there, locate the ‘Realtek Controller’ option and click on it too.
  • Select the Manual Mode when you want to update the driver
  • Pick the drivers you would like to update
  • Wait while the computer searches for the drivers needed for an update
  • Install all the updates and then reboot your system

Download the right driver

Should your system fail to find driver updates that need to be installed, all hope is not lost. You can by yourself download the drivers from the Realtek website. Follow these simple steps to do so

  • Enter the address – www.realtek.com/downloads into your web browser
  • Search for the driver that works well with the OS of your computer. The one that would work with a Windows 10 PC is different from that of a Windows 7 PC.
  • Click on the driver and download it
  • Install the driver you just downloaded on your computer

Once you install the driver, the Realtek issue should be immediately fixed. However, if it isn’t, go back to follow the steps in Method 1 after the computer has downloaded a driver. However, as a Realtek software issue might not give you internet access on your system. This means you will not even be able to access the web page to start with. In that case, all you have to do is to download the driver on another system that is working well. Once that’s done, transfer it to the affected system and then, install it.

On the other hand, you can download the Driver Easy software. The software would automatically find the appropriate drivers that your computer needs. It recognizes your system and knows the drivers that are perfect for it. It also has an Offline Scan feature. This makes it possible to download thenetwork driver without an internet connection. Start by downloading Driver Easy on another system and installing it on the affected one. Locate the Offline Scan feature. Then, use it to download and update the Realtek PCIe GBE driver. There is a guide on the Driver easy to help you with this. It outlines how to use the Offline Scan feature to get the network driver updated.

Perform a System Restore

This is another tested and trusted method that is worth trying. The catch, though, is that it could make your PC unstable. So, you should only make use of it when methods 1 and 2 fail to work. Performing a system restore on your computer would do just what its name says. It would take your system right back to how it was without any issues. To achieve this, these are the steps to follow


  • Access the Run box by pressing the R and Windows button at the same time
  • Into the box, type in ‘rstui.exe’ and press the Enter button on the keyboard or simply click on the one on the screen
  • Click on the button that says ‘Next’. Then, type in the date you would like your system to go back to.
  • After entering the date, wait until the system completes the process
  • Once the system restore process is over, the computer would reboot on its own
  • When the computer powers on, check to confirm that the error has gone.


Use the Registry Editor

You should go for this just in case the idea of performing a system restore does not tickle your fancy. It is just as effective as other methods. Here’s how to go about it

  • Go to the Start menu of your computer. Into the search box, type in ‘Command Prompt’ and then, search for it
  • Right-click Command Prompt. From the list of options, choose ‘Run as administrator’.
  • Type in the ‘netcfg-s n’ command
  • Search for DNI_DNE
  • When you find it, type in the command below

reg delete HKCR\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3}/va /f

netcfg –v –u dni_dne

The command might seem like a handful but best believe it would fix the driver issue immediately. In the rare case that you get an error message, no need to fret. Follow the steps below

  • Open the Run box the same old way. By pressing both the Windows and R buttons together
  • Into the box, type in ‘regedit’ and press Enter
  • Search for HKEY_CLASSES_ROOT\CLSID{988248F3-a1ad-49bf-9170-676cbbc36ba3} and then delete it
  • Then, try the command prompt once again


Replace the Network Adapter

Hoping this method would be the solution to the issues your system has because the 4 above did not work? Here’s the sad truth. The issue your system has is most likely not related to the Realtek software. It is probably a hardware problem. This means your PCIe network adapter has worn out. So, you would have to buy a brand new one. All you have to do is walk into any reputable computer store. The price of a PCIe network adapter is very affordable. That aside, you don’t have to worry about how to remove the old one and install the new one. The technicians in the computer store would be happy to do it for you. If this does not still fix the problem, then you might want to turn the system in for a professional to examine it.
