Title: SOLVED: Realtek 8723DU Wireless LAN 802.11n USB NIC Driver for Windows 11

Post:

If you have a USB Wi-Fi adapter based on the Realtek 8723DU chipset (often labeled "Wireless LAN 802.11n USB NIC") and it stopped working after updating to Windows 11—or Windows 11 doesn't recognize it at all—here's how to fix it. Method 3: The GitHub "Open Source" Fix This

The problem:
Windows 11 does not include native drivers for the 8723DU. Plugging it in may show as "Unknown USB device" or fail to enable Wi-Fi. The old Windows 10 drivers often cause code 10, code 31, or constant disconnections.

The solution:
Do not rely on Windows Update. Use the correct driver directly from Realtek or an official OEM source.

Method 3: The GitHub "Open Source" Fix

This is where it gets "interesting" for tech enthusiasts. Because Realtek is slow to update drivers for specific USB variants, the open-source community often fixes bugs faster than the corporation.

1. Go to GitHub and search for Realtek driver or specifically repositories maintained by developers like gordboy or RinCat.
   • Specific Repo: Look for rtl8723du repositories.
2. These developers wrap the official Realtek source code into cleaner installers that work better on Windows 11 builds (22H2/23H2).
3. Download the latest release .zip or .exe from their Releases page.

Troubleshooting Common Issues

1. The "Code 10" Error If the device starts but stops (Code 10), it is usually a power management issue.

• Go to Device Manager > Right-click adapter > Properties > Power Management.
• Uncheck "Allow the computer to turn off this device to save power." The 8723du is sensitive to USB power cycling.

2. Slow Speeds / Dropping Connection The 8723du is an 802.11n (Wi-Fi 4) chip. It is older technology. Do not expect Wi-Fi 6 speeds.

• Ensure your Router is set to broadcast on 2.4GHz. This chip struggles significantly with 5GHz if the signal isn't perfect.
• Change the USB port. If you are using a USB 3.0 port (Blue), try a USB 2.0 port (Black). Sometimes interference from USB 3.0 frequencies messes with the 2.4GHz Wi-Fi radio inside the dongle.

Error Code 31: "Drivers are not installed"

• Cause: Corrupt driver cache.
• Fix: Delete the driver files in C:\Windows\System32\DriverStore\FileRepository related to Realtek (use pnputil /enum-drivers to list them), then reinstall from scratch.
