Maybe it has something to do with "no Metric settings" on the Adapter? If you read out the connection, Metric on Ethernet 2 (Juniper Adapter) is not set? Is there an option to change it from auto to fix? maybe 5 oder 10?
I had the same issue.
Found this driver and it is working perfect on 22593 Build.ni_release.220402-1100.
Do we see this issue while running Windows 11 GA release or only on dev preview builds?
