Sharing the link on where you can find registry location of network adapter parameters
If one of the 3 other PC's have dual LAN ports, you may want to try out Internet connection sharing to further isolate the problem.
Internet router <--- LAN 1 --- PC --- LAN 2 <--- Win10 PC
Hope this help.
Thank you so much for getting back to me and my apologies for the time it has taken me to get back to you, I have been interstate.
I tried the Registry editing (twice) per the article in the link, unfortunately I was unsuccessful in getting an internet connection. Also, the same network connection number came back, so perhaps I didn't follow the instructions exactly. I am cautious when editing the registry. The second article (within the above article) mentioned another approach on removing the installation PROSET.MSI. using msizap? I haven't tried this as I wonder if it applies in my case? and I don't want to create a larger problem.
All the other PC's only have single Ethernet ports so sharing isn't possible (great tip though!).
The final suggestion in the original article was to reinstall Win 10, that I guess is my next step. Do you have any other suggestions?
Thank you so much for your help.
