| Symptom | Likely Cause & Solution | | :-------------------------------------------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | This is extremely common and usually means only the wireless driver is installed. Solution : Manually install the Bluetooth driver using the AR3012 device ID. | | Card not found in Device Manager at all | The card may be disabled in the BIOS, not seated properly, or a hardware conflict exists. Solution : Check your BIOS settings to ensure the wireless card is enabled. If it is, power down, reseat the card, and restart. | | "Driver is not intended for this platform" | This error occurs when the wrong driver architecture is used. Solution : If you are on 64-bit Windows, double-check that you selected athwbx.inf . For 32-bit Windows, use athwb.inf . | | Intermittent Connection or Low Speed | This can be caused by power management or channel interference. Solution : On Linux, disable power management as described above. On any OS, try changing your router's Wi-Fi channel or force the connection to use only the 2.4 GHz or 5 GHz band. For OpenWRT, try temporarily switching bands. | | Yellow exclamation mark in Device Manager | This indicates a driver problem. Solution : First, try updating the driver automatically.
