Microsoft has fixed a known issue causing Wi-Fi network connectivity problems on Windows 11 systems triggered by recently released cumulative updates.
The company confirmed the issue on Tuesday after a massive stream of user reports on Reddit, Twitter, and Microsoft's own community platform and after several universities issued advisories advising students and staff to uninstall the KB5033375 update.
The known issue impacts only client platforms, with Windows 10 devices not likely affected by these Wi-Fi connectivity problems.
There is currently no information to suggest that this issue is linked to any specific wireless network adapter models.
Microsoft resolved this widespread known issue through Known Issue Rollback, a Windows feature that helps reverse flawed non-security updates delivered via Windows Update.
The fix might need up to 24 hours to roll out to all impacted consumer and non-managed business devices.
For quicker deployment, users can also reboot affected Windows 11 devices.
Redmond also provides a KIR Group Policy to address the Wi-Fi connectivity issues on impacted Windows enterprise-managed devices.
On the list of installed updates, select KB5033375, and then click the Uninstall button next to it.
Use the 'Show or Hide Updates' troubleshooter to prevent the update from reappearing as an available update from Windows Update.
After the update is uninstalled, restart the computer.
This week, Redmond also released a troubleshooter tool to remove the HP Smart app after it was automatically installed on Windows, and all printers were renamed to HP LaserJet M101-M106 on impacted devices.
