Hi Meghmala,
I am having the same issue and all the steps you mention in your post has been followed to no success.
How it started for me:
Created a new Windows 10 Pro machine, configured and got access to the Internet. I cloned that setup to another identical machine. Under the device manager, all devices are installed correctly. The network card too and I can remotely connect to the newly
cloned machine. But the machine fails to connect to the Internet.
Uninstalled / installed network card drivers several time and still the same issue. All necessary services to have Internet connection are running.
The original machine is fine and have access to the Internet. The cloned machine fails to connect with network connections functioning fine.
I hope you can give me some clues where to look.
Thanks,
Ben
