Could you post the results of a command prompt ipconfig /all ?
I suspect that your Ethernet adapter will have an address like 169.254.y.z, a default for Windows.
And what version of Windows do you use, 10 Home, or?
Many thanks, I am using Windows 10 Home. Based on something I saw online, I have fixed my IPV4 address/DNS and the ethernet was working again.
However, I had to use my laptop in my living room so I switched it to wifi and as usual, the ethernet doesn't work again when I am back in my room.
As SamirD mentioned, Windows may be confused with the back and forth but I don't remember this being a problem before (maybe only this past 6months?)
