Troubleshooting Tips

• Bluetooth not working? The RTL8723DU is a combo card. The WiFi driver handles the network. If Bluetooth isn't working, you need a separate "Realtek Bluetooth" driver, which usually installs alongside the WiFi driver but sometimes requires a separate manual install in Device Manager.
• Windows 10 vs. 11: In most cases, a Windows 10 driver for the RTL8723DU will work perfectly on Windows 11. If you cannot find a specific "Windows 11" version, download the latest Windows 10 version (x64).

1. Extract the downloaded file (it acts like a ZIP file).
2. Open Device Manager (Right-click Start button > Device Manager).
3. Find your device (it may be under "Other devices" with a yellow triangle, or under "Network adapters").
4. Right-click the device and select Update driver.
5. Select Browse my computer for drivers.
6. Select the folder where you extracted the files.
7. Windows should pick up the .inf file and install it.
