Win11 kills network connections after a few minutes

[Tom]

I was originally able to run Win11 without problem. Then an update killed any network connection (both wired and wifi). This forces me back to Win10.
Whenever I try again to run Win11 I get the same result. It will appear to load correctly but then disconnects all the network connections. I thought this might be a windows fire wall issue but even if I turn off the firewall it occurs. Any suggestions? Thanks

Keep windows 10

It happened again.
I installed 10.0.22000.160 (co_release) and that seemed to work fine, however when an update
KB5005635 installed it killed all my internet connections after a few minutes.
