Updating Network Adapter Driver in Windows 10 and 11

Introduction / Why This Matters

A network adapter is your primary gateway to the internet and local network. An outdated or corrupted driver is one of the most common causes of connectivity issues: no internet, slow speeds, Wi-Fi drops, or errors like 0x8007045D, Code 31, and others. Regularly updating your driver ensures stable network performance, patches security vulnerabilities, and adds support for new protocols. This guide will walk you through three reliable update methods for Windows 10 and 11.

Requirements / Preparation

Before you begin, ensure:

• You have administrator privileges on the computer.
• You have a stable internet connection (you can temporarily use Ethernet or another Wi-Fi adapter if the primary one isn't working).
• You know your network adapter's model (see step 1) or the model of your computer/laptop.
• It is recommended to create a system restore point in case something goes wrong (Control Panel → System and Security → System → System Protection → Create).

Step-by-Step Instructions

Method 1: Update via Device Manager (Easiest)

This method uses drivers already included with Windows or that Windows can automatically fetch.

1. Press Win + R, type devmgmt.msc, and press Enter.
2. In the window that opens, find and expand the "Network adapters" section.
3. Right-click your network device (e.g., Intel(R) Ethernet Connection I219-V) and select "Update driver".
4. In the window that appears, select "Search automatically for updated driver software".
5. If Windows finds a newer version, it will install it automatically. After completion, restart your computer.
6. If the system reports that the best driver is already installed or finds no updates, proceed to Method 2.

Method 2: Download and Install from the Manufacturer's Website (Recommended)

This is the most reliable method, as you get a driver optimized specifically for your hardware and Windows version.

1. Identify the exact model of your network adapter (step 1 in howToSteps above).
2. Open your browser and go to the official website:
   • For a pre-built PC/laptop: the manufacturer's site (Dell, HP, Lenovo, ASUS, Acer, etc.). Look for a "Support" or "Drivers & Support" section.
   • For a custom-built PC: the website of your motherboard manufacturer (Gigabyte, MSI, ASRock, etc.) or the network chipset manufacturer (Realtek, Intel, Broadcom, Qualcomm Atheros).
3. Enter your computer's serial number/model or select your motherboard model from the list.
4. In the drivers list, find the "Network", "LAN", or "Wireless" section.
5. Select the latest driver version compatible with your Windows version (10/11) and system architecture (64-bit).
6. Download the installation file (usually .exe or .zip).
7. Run the downloaded .exe file and follow the installation wizard's instructions. Restart your computer after completion.
8. If you downloaded a .zip archive, extract it. Then in Device Manager (step 1), choose "Update driver" → "Browse my computer for drivers" → "Browse" and point to the extracted folder.

Method 3: Using Third-Party Software for Bulk Updates (Caution!)

There are programs (e.g., Driver Booster, Snappy Driver Installer) that automatically scan and update all drivers, including the network adapter.

⚠️ Important: Use such programs with caution. They may offer non-optimal or unofficial driver versions, which can sometimes cause instability. Always create a restore point before using them. For critical components like the network adapter, Methods 1 and 2 are preferred.

Verifying the Result

After restarting, confirm the driver was updated:

1. Open Device Manager again (devmgmt.msc).
2. In the network adapter's properties (right-click → "Properties"), go to the "Driver" tab.
3. Check the "Driver Version" and "Driver Date" fields. They should match the version you installed.
4. Test your network: open several websites, check Wi-Fi speed and stability.

Potential Issues

• "Failed to find driver for this device" after update: This usually means the installed driver version is incompatible with your Windows. Boot into Safe Mode (hold Shift while clicking "Restart" in the Start menu → Troubleshoot → Advanced options → Startup Settings → Restart → press F4). In Safe Mode, roll back the driver via Device Manager (Driver Properties → "Driver" tab → "Roll Back Driver").
• No internet to download the driver: If the network isn't working at all, use another computer or mobile internet (via USB modem or phone tethering) to download the driver and transfer it to the problematic PC using a USB flash drive.
• Driver installer reports a compatibility error: Ensure you downloaded the driver for the correct architecture (x64) and Windows version. Check your Windows version (Win + R → winver).
• Network performs worse or stops working after update: Create a restore point before installing the new driver. If an issue occurs, perform a System Restore to that point (Control Panel → Recovery). Then try a different driver version (e.g., an older, stable one) from the manufacturer's website.
