Latest Windows 11 October patch created some network issues

While many Windows 11 users were happy to see new updates for versions 21H2 and 22H2, they didn’t come without issues. Even Windows 10 and other older versions were affected, leading to network-connectivity issues. Microsoft is aware of the problems and has issued a report on how you can deal with them.

The October patches for Windows 11 were KB5018418 for version 21H2 and KB5018427 for version 22H2. While they addressed may fixes we sorely needed, it seems as if it added some more problems. One of these is connecting to networks, which may affect many businesses running this operating system on corporate computers.

Microsoft issued a report stating what was causing the problem. Apparently, it has to do with an SSL/TLS handshake gone wrong. From what I understand, your computer is trying to send multiple frames at a time toward one input buffer, which is what may be causing the problems. The network struggles with this input, and then it can’t connect. 

There’s an easy way to deal with this issue. When you press Windows + F keys, you’ll see the Feedback Hub. You’ll need to complete the fields before recording your screen and performing the action again. From there, the form will head to the experts to help you resolve the Windows 11 network connection. 

If you have Windows 11 21H2, you should already have received an OOB update number KB5020387 with an automatic fix. For 22H2, there isn’t a solution yet except to report the matter above. Any other Windows versions will have to follow the same feedback route at the moment.

At least the new Windows 11 update lets you free up space on your storage. It’s a welcome feature, considering how much space the operating system takes already.
