One of the most annoying problems that we can face when we use a computer is that we have intermittent cuts in the Internet, it malfunctions or it cuts out. At that time, tasks as basic as browsing the Internet, downloading a file or watching a streaming video, for example on YouTube, can be torture. These types of errors, on many occasions, have to do with the software installed on our computer. In these cases, these failures often have a very clear culprit: the network card driver in Windows. In this tutorial we are going to learn how to reinstall the Wi-Fi network card driver in Windows to solve Wi-Fi problems.

The first thing we are going to do is explain the reasons why this failure occurs in Windows. Then we will explain step by step the process of reinstalling the network card driver in Windows 10 to solve Wi-Fi problems through a practical example.

Reasons for reinstalling the WiFi card driver

From the moment Windows starts and we start using it, we can find multiple problems related to wireless connections. Among them we find a series of problems when trying to connect to a Wi-Fi network such as:

  1. Some annoying random cuts that are repeated over time, and that cause us frustration.
  2. The time may come when we simply do not see any network within our reach.

As we have already mentioned, on many occasions these problems are caused by the Wi-Fi network card driver . The reasons why this problem usually happens are:

  • The driver or driver is incorrectly installed.
  • It has become corrupted or has stopped working for some reason.
  • A Windows update has caused it to stop working properly. This usually happens after the important updates that this Microsoft operating system usually offers every 6 months.

As for the problems that we can find, if we do not have the WiFi network card driver updated, it would be a malfunction of the network connection, we could be exposed to security vulnerabilities and also have conflicts with the operating system in which we could get a screenshot. In the worst case it would be the blue screen of death.

In this article we recommend that, if after putting the latest version of the driver we continue to have problems, we should review the configuration of our network equipment. We will have to check if the router broadcasts on the appropriate channel, we connect to the corresponding band, or if we would need to add a Wi-Fi repeater or Wi-Fi mesh system.

Things to consider before uninstalling the driver

If we want to do things correctly in the process of uninstalling the Wi-Fi network card driver from our computer, we must take into account several factors.

One of them is that we are going to lose the Internet connection . Therefore, a good idea, if possible , would be to connect to the router by Ethernet network cable . In the case of laptops this operation is simpler, but if it is a desktop computer and we do not want to move it, it may be more interesting to download the driver from the manufacturer’s website.

Another very important thing to keep in mind before starting the procedure is that after uninstalling and reinstalling the Wi-Fi driver, all the passwords of the Wi-Fi networks that we have stored will be deleted. Therefore, before we begin we must make sure that we do not lose any that are of vital importance to us. Thus, it is best to look at the keys first and write them down before starting the procedure.
