Windows 11 has stricter driver signing requirements and a new network stack. The default inbox driver (Microsoft’s Generic NDIS driver) does not unlock the full hardware capabilities of the RTL8812BU. It forces the card into a "compatibility mode" that caps speeds at 150 Mbps and frequently drops the connection during heavy load.

: For the safest "official" option, you can search for "Realtek 8812BU" on the Microsoft Update Catalog to find signed WHQL drivers. Installation Tip

Do not use the default drivers from Windows Update (they often cause low signal or disconnects).
