Windows 11: Security update paralyzes WLAN

A security update for Windows 11 and other Windows systems has fatal consequences.

The patch day in June 2022 not only causes WiFi problems on some Windows 10 computers, but also Windows 11 users and users of older Windows systems have to nibble on the consequences. As the US IT news site Betanews reports, the important security patch KB5014697 ensures that the WLAN function no longer works on some Windows 11 computers. Microsoft describes the problem and its workaround as follows: ”

After installing KB5014697, Windows devices may not be able to use the Wi-Fi hotspot feature. When attempting to use the hotspot feature, the host device may lose connection to the Internet after a client device connects.


To mitigate the problem and restore internet access on the host device, you can disable the Wi-Fi hotspot feature. For instructions, see Use Windows PC as a portable hotspot.

Next Steps:

We are currently investigating the issue and will provide an update in a future release.

Specifically, these operating systems are said to be affected by the WLAN problem:

  • Windows 11 version 21H2

  • Windows 10 release 21H2

  • Windows 10 release 21H1

  • Windows 10 version 20H2

  • Windows 10 Enterprise LTSC 2019

  • Windows 10 Enterprise LTSC 2016

  • Windows 10 Enterprise 2015 LTSB
