Ethernet doesn't have a valid IP configuration [Windows 10]

[Jesper_3]

At the main floor I have a Router linked to a Powerline adapter with a cable. On the second floor I have another adapter linked to my PC. I installed it a week ago and it worked fine until yesterday. Its says that the Ethernet Doesnt Have A Valid Ip Configuration and it has a yellow warning triangle. I already tried to fix it with ipconfig and release, flushdns, renew etc., but it just doesnt work. I saw man other solutions and I tried some but don't know exactly which and it none worked. A remarkable thing is that I see a blank field whenever I type '"ipconfig all" at "Default Gateway"

I am getting really frustrated and I will be as cooperative as possible

Thanks!

Update drivers, and check your adapter settings in control panel. You might have your IP address or default gateway set to static instead of DHCP.
