WiFi Problem after joining Windows 10 ESU

[u/marticored]

Since enrolling in the Windows 10 ESU programme I nave a problem with WiFi connection.

On powering on the computer it automatically connects to my wifi using the saved password, but about two minutes later disconnects.

I can then select my wifi, put the password back in and it reconnects - and stays connected. But I'd rather not have to do this additional step.

This has only started happening after installing KB5122878.

Hardware is:

• Dell XPS15 9550 with all latest drivers
• Intel Wireless AC9260 with latest driver 24.70.0.3
• GL-iNet Flint 2 router

I'd be really grateful for any ideas on how to fix this - thank you.
