Windows 10: Network ethernet problem

I have a very odd problem with a brand new Windows 11 computer. Everything works great except for one thing. I have an ethernet network here with 5 Windows computers on it. Three are legacy Windows 7 computers that are needed for legacy software and hardware. The other two computers are newer and both have Windows 11 installed.

Ethernet Light Orange/ "Local Area Network" Not in Network List

Last night I noticed my ethernet light on the back of my computer was orange. I did some research to find the reason. Some websites said it was an increased connection speed. Others said a problem with the connection.
The local area network is no longer in the list of network connections and the other computer in my house has a green light on the ethernet port.
I've used all the cmd.exe ipconfig steps suggested by websites. Flush dns, reset dns, etc. I've also used the network troubleshooter in windows10 which told me a problem was not found.
Nothing seems to change the light back to green. Can someone help me find the problem so I can fix it?
