    Hi RoyHollett,

    Error code 43 denotes that one of the drivers controlling the device notified the operating system that the device failed in some manner.

    Method 1:

    You may try running the Hardware Troubleshooter to diagnose the issue better.

    Refer the link below:

    Method 2:

    Download and install the latest wireless network adapter drivers from the computer or device manufacturer and check.

    Refer the link:

    Hope this information is helpful.

    Try this:

    Open "Device Manager"

    Right-Click your Wifi Adaptor and select "Properties"

    Disable and Re-enable the adaptor.

    But my pc that encounters this problem cannot be connected to Internet when the wifi adapter doesn't work, how can I access the troubleshooter or update the driver in this case ?

    If that doesn't work, what is the next best option? I'm in the same boat with a Lenovo Desktop H520 series. It enables for a few seconds and then errors back out.
