Strange "Local Area connection" doesn't have a valid IP configuration

Hi all,

My Windows 10 x64 is connected to the ADSL modem accessing the Internet and alongside another machine running Windows 7 x86 is also connected to another port of the modem (both via Ethernet cable)

The windows 7 machine has a yellow warning sign on the Internet icon and when trying to fix it says: "Local Area connection" doesn't have a valid IP configuration.

I don't know how to solve it. The Ethernet driver is installed and device manage shows no issues.

How to solve this strange problem, please?

I unplugged the Ethernet cable to Windows 10, just to test, but yet the Windows 7 machine didn't work!
