Windows cannot initialize the device driverfor this hardware (Code 37) - for all network adapters


  • hi,

    I restarted my computer and found that none of my network adapters were working (Wireless as well as wired). When i went to device manager i got the Code 37 error code for the following devices:

    Bluetooth LAN Access Server Driver -
    Packet scheduler Miniport
    Intel(R) PRO/Wireless 2200BG Network Connection - Packet scheduler Miniport
    Realtek RTL8139 Family PCI Fast ethernet NIC -
    Packet scheduler Miniport
    WAN Miniport (IP) -
    Packet scheduler Miniport
    WAN Miniport (PPTP)

    the system did not display any error for the following devices

    Intel(R) PRO/Wireless 2200BG Network Connection
    Realtek RTL8139 Family PCI Fast ethernet NIC

    I uninstalled the drivers for the above 2 devices and re-installed them after re-starting my computer but still got the same error.

    Help Please....

  • Cause

    There are several causes of Code 39 errors:
    A required device driver is missing.
    A required binary file is corrupted.
    There is a problem with the file I/O process.
    A driver that is referencing an entry point in another binary file is unable to load.
    Recommended resolution

    Reinstall the drivers for this device.

    Uninstall and reinstall the driver

    Uninstall the driver from Device Manager, and then scan for new hardware to install the driver again.

    You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have the driver files installed from the last time that you set up the device. However, sometimes, it will open the New Hardware Wizard which may ask for the driver. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor’s Web site.
    On the device Properties dialog box, click the Driver tab, and then click Uninstall. Follow the instructions.
    Restart your computer.
    Open Device Manager, click Action, and then click Scan for hardware changes. Follow the instructions.
