Many users make the mistake of letting Windows Update install a stripped-down, "generic" driver. The "full" driver package is critical because it includes:
| Feature | Generic Driver | Full Driver (11ax22ww) |
| :--- | :--- | :--- |
| Bluetooth 5.2/5.3 | Limited or missing | Full BT stack included |
