Part 2: Symptoms of Missing or Corrupt Realtek 8723DU Drivers on Windows 11

How do you know the driver is the problem? Look for these telltale signs after plugging in your USB adapter:

No Wi-Fi Icon in Taskbar : The globe icon appears with "No Internet Access" or the Wi-Fi section is completely missing from Settings.
Unknown Device in Device Manager : Open Device Manager (Win + X > Device Manager). Under "Other Devices," you will see an "Unknown Device" or "Network Controller" with a yellow exclamation mark.
Code 52 Error : Windows cannot verify the digital signature for the drivers. This appears as "Windows cannot load the device driver because it is not digitally signed or has been altered."
Code 10 Error : This device cannot start.
Intermittent Connection : The Wi-Fi works for 5 minutes, then disconnects, requiring a reboot.
Limited to 802.11b speeds : You connect, but speeds max out at 11 Mbps because the driver is defaulting to legacy modes.

If you see these, the default Microsoft driver (released via Windows Update) is incompatible, or you are using a legacy binary driver from 2015.
