Intel updated the Wi-Fi Drivers to solve various problems in Windows 10

3 min read

Intel has recently released wireless network card driver updates, these drivers were originally used to solve the Windows 10 blue screen of death. Unfortunately, there are problems with the wireless network card drivers that were launched at this time.  Recently, Intel updated the Wi-Fi Drivers (21.120.2) to solve various problems in Windows 10.

For this type of driver that is prone to stability problems, our suggestion is to not upgrade for the time being if there is no major problem with the current version.

Because Intel’s wireless network card driver is similar to the cumulative update of Windows 10, although it will fix old problems every time, it also brings some new problems.

The safe way is not to upgrade for the time being. After a period of time, see if Intel quickly releases a new version of the fix to know if there are other problems with the current version.

In addition, if there are many problems with the currently installed drivers, you can upgrade. If the problem cannot be solved after the upgrade, please roll back the old version of the driver in the device manager.

Intel emphasizes that this driver contains security updates. From a security perspective, users should upgrade to the latest version to ensure that vulnerabilities in the old version can be blocked.
