Answer 2

Code 43 indicates that a device has reported a failure to the operating system. When you see this error while trying to connect to WiFi on your laptop, it means that the driver for the wireless device has encountered a problem and has informed Windows that the device has failed. The typical resolution for this issue is to uninstall and then reinstall the device driver associated with the WiFi adapter. This can often resolve the underlying issue causing the failure.
