• Windows 11’s built-in driver (dated 2019) caused frequent dropped connections and limited 2.4 GHz performance.
• Realtek’s official site is confusing – the driver labeled “for 8723du” is buried under “USB Wireless LAN card ICs” > RTL8723DU.
• The installer didn’t run on first try; I had to disable driver signature enforcement temporarily (not ideal for average users).

1. Download driver version 1030.45.0421.2021 (or newer) from Realtek’s official download center.
2. Disable Wi-Fi adapter in Device Manager, uninstall old driver, then run setup as admin.
3. After install, set power management to “disable” for the USB adapter in Device Manager > Properties > Power Management.
