Realtek RTL8168 8111 PCI E Gigabit Ethernet NIC Driver

The Realtek RTL8168 8111 PCI E Gigabit Ethernet NIC driver enables Windows to communicate with your RealTek PCI Express network adapter for wired Ethernet access. It is useful after reinstalling Windows, when the adapter appears as an unknown device, or when troubleshooting a missing or unreliable wired connection.

Key Features

• Wired network connectivity: Enables compatible RTL8168/8111 adapters to connect to a router, switch, or local network through an Ethernet cable.
• Gigabit Ethernet support: Supports connection speeds up to 1 Gbps when the adapter, cable, and connected network equipment support them. Actual transfer speeds depend on network conditions.
• Windows compatibility: Driver packages are available for Windows 11, 10, 8, and 7, but you must select a release that matches your operating system and hardware revision.
• Adapter configuration: Integrates the network adapter with Windows networking tools and Device Manager, where you can check device status and access settings supported by your driver release.

How to Install Realtek RTL8168 8111 PCI E Gigabit Ethernet NIC Driver

1. Confirm your adapter and Windows version. Open Device Manager and check under Network adapters or Other devices. If the adapter is unidentified, use its Hardware IDs under Properties > Details to help verify compatibility. Also check whether Windows is 32-bit or 64-bit.
2. Choose a matching package. For a Realtek RTL8168 8111 PCI E Gigabit Ethernet NIC driver download for Windows, use a trusted manufacturer source offering a free download. Select the latest version that explicitly supports your adapter and operating system; a Windows 10/11 package may not support Windows 8 or 7.
3. Prepare the files. Download the package and extract it if necessary. If the computer has no internet access, download it on another device and transfer it using a USB drive.
4. Install the driver. Run the included installer and follow its prompts. If no installer is provided, open Device Manager, right-click the adapter, select Update driver, and browse to the extracted driver folder.
5. Restart and test. Restart if prompted, connect your Ethernet cable, and confirm that Windows detects the wired connection. Check Device Manager for any remaining warning icons.

Keep the driver updated when a compatible release addresses connection problems, security concerns, or operating system changes. Before an update, review the release notes and compatibility details rather than assuming every newer package is suitable for your adapter.

Common Issues and Fixes

• Install fails or rolls back: Use the package matching your exact RTL8168/8111 revision and Windows architecture. Run the installer as administrator, temporarily disable antivirus/VPN, and remove any existing Realtek NIC driver in Device Manager, including “Delete driver software,” before rebooting.
• Device not detected: Confirm the adapter is enabled in BIOS/UEFI and seated correctly in the PCIe slot. In Device Manager, scan for hardware changes; if it appears as unknown, install the motherboard vendor’s RTL8168 INF package, as OEM builds may differ.
• Version conflicts after Windows Update: If throughput drops or the adapter disappears, use Device Manager > Properties > Driver > Roll Back Driver, or uninstall the generic Microsoft driver and reinstall the Realtek/OEM version. Block automatic driver replacement in Windows Update if it recurs.
