Issue: How to fix Network adapter error (Code 31) in Windows?

Hello. Suddenly the network adapter stopped working properly on my Windows computer. I also receive an error with Code 31. What should I do?

Solved Answer

A network adapter, also known as a network interface card (NIC), is a hardware device that is installed in a computer and enables it to connect to a network. In Windows, the main function of a network adapter is to provide a connection between the computer and the network, allowing the computer to communicate with other devices on the network and access network resources such as the Internet.

If you are experiencing an issue with your network adapter in Windows, it is possible that you may see an error (Code 31) indicating that the device is not working properly. This can be a frustrating problem as it can prevent you from accessing the internet or other network resources. The full error message reads as follows:

This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

There are a few different steps you can try to fix this issue and get your network adapter working properly again. The first thing you should do is to make sure that the device is properly connected to your computer. Check the cables and connections to ensure that they are secure and not damaged.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
