i got same problem on my build that i finished yesterday windows 11 22h2 full updated on a z790-e, but i solved it setting card to full power, speed forced 1gbit and installed latest intel network adapters full pack , https://www.intel.com/content/www/us/en/download/15084/intel-ethernet-adapter-complete-driver-pack.h...
Yeah thanks a bunch! Forcing 1gbps speed is probably what fixed the issue.
had same issue actually fixed it by tweaking the settings Ã‚*
In control panel
In the i226-v advanced tab
If you want I can send to you.Ã‚*
