S23 Ultra/Windows 11 - hotspot connection keeps dropping

[9876_Martyn]

I have an intermittent but persistent problem - ie when it is a problem it is constant, but then it just stops happening for weeks at a time.  Windows will connect to the S23 Ultra hotspot for a few minutes, then drop the connection saying that details of the network have changed and asking for the password again.

Every other device maintains a stable connection to the phone, and the PC maintains a stable connection to every other WiFi source.  The phone's internet link works fine if I connect by USB, it is only a WiFi issue.  I've tried all obvious fixes, changing the WiFi frequency/bands etc. , reset PC network settings, changed the WiFi name and password removed PC network device, reinstalled drivers etc. etc.  PC is a recent-ish Dell laptop with their "Killer" WiFi that supports both WiFi6/.ax and 6E/6 ghz.

help?!

Do you have battery saving mode turned on?

Thanks for the suggestion but no, it isn't a battery management problem. (A) I'm not in any power saving mode, and (B) every device except Windows maintains a perfectly stable connection to the hotspot

Hmm What happens if you disable the power saving option in your wireless network card?
