Realtek PCIe GbE Family Controller Driver for Windows

The PCIe GbE Family Controller package is kept here for Windows users who need the adapter working again after a clean install, a network reset, or a missing-device warning in Device Manager.

PCIe GbE Family Controller driver overview

This page keeps a local copy of the Realtek ethernet controller driver with the version, supported Windows releases, file size and checksum shown before download. It is meant for people who already know the adapter model and want a clean installer without jumping through several support pages.

When this network driver helps

• Windows shows the adapter as unknown or missing after reinstalling the system.
• Wi-Fi, Ethernet or Bluetooth is present in Device Manager but the connection is unstable.
• You need the vendor package with a visible checksum and source reference.

Supported Windows versions

Windows 11 / 10 are listed for this package. Match the adapter model and Windows version before running the installer.

Before installing

Download the file from this page, compare the file size and checksum when possible, close open network utilities, then run the installer as administrator. Reboot if Windows asks for it before testing the adapter.
