In this guide, you will learn how to resolve error 10 for Realtek PCIE GBE Family Controller driver
There may be several reasons for this error, but there are two main reasons:
- Incorrect driver operation.
- Physical breakdown of the adapter.
First, we recommend updating the driver. For this:

Use the Windows key + R keyboard shortcut. In the field that appears, type devmgmt.msc and click OK.
The device manager will be displayed. Expand Network adapters. Right-click on the Realtek PCIE GBE Family Controller, click on Update Driver.

Newer versions of Windows successfully update the driver in auto mode. Click on the words Automatically search for updated drivers.

Wait while the operating system searches for an updated driver. If necessary, install the new software version.
If you are using the latest driver, you will display a message like the one below.

If you have disabled automatic search for drivers on Microsoft servers, try installing the latest driver on your network card yourself by downloading it from here.
If updating the drivers does not help, check that the network cable is fully plugged into the connector. And, if possible, test the operation of the network card in another computer (if it is external).
If the network card also does not work on another computer, it is likely that the device is physically out of order. It needs to be tested in a specialized service center.
The most common reason for a breakdown of network cards is lightning striking the equipment of a provider that does not use appropriate protection. If you are using an external network card, it is easier to replace it.
If a chip integrated into the “motherboard” fails, most likely you will have to replace the entire board. Or buy a separate network card. In this case, we recommend that you take care of the protection in advance and install special equipment-grounding.
