Yes. There are known Windows 11 updates that caused Wi‑Fi issues, and Microsoft has released fixes for them.
From the provided information:
- Updates KB5032288 and KB5033375 introduced a problem where some Wi‑Fi adapters could not connect to certain networks, especially enterprise/education/public Wi‑Fi using 802.1x authentication. Home networks were less likely to be affected.
- This issue is explicitly confirmed as caused by those updates.
- Microsoft has released a fix in update KB5034123. Installing this update addresses the Wi‑Fi connectivity problem.
- For devices managed in enterprises, Microsoft also provided a Known Issue Rollback (KIR) policy and a special Group Policy package to roll back the problematic change. For consumer devices, KIR is applied automatically, but it can take up to 24 hours and may require a restart.
To safely update again:
- Allow Windows Update to install the latest cumulative updates that include KB5034123 or later.
- Restart the device after updates are installed.
- If the device is enterprise‑managed and still affected, the admin can deploy the KIR Group Policy for the relevant Windows 11 version as documented.
With KB5034123 (or newer) installed, the specific Wi‑Fi issue caused by KB5032288/KB5033375 should no longer recur, so the device can be updated again without hitting the same bug.
