Why is my Ubuntu laptop not connecting to the Internet?
My laptop running Ubuntu 20.04 is connected via ethernet to the secondary router (WNDR4000). As you mentioned, your machine isn’t able to connect to the internet when connected via ethernet to your secondary router, but when connected by ethernet to your main router, it works. I have this same exact issue with my setup.
Why is my Ethernet not working in Ubuntu 18.04?
I had the same problem – my newly-installed Ubunut 18.04 wasn’t detecting my ethernet connection for a second, though the led at the port was constantly blinking as if it were normal. I typed lshw -C at the terminal and among the output displayed there was no eth0 ( it refers to ethernet connection, no eth0 means no ethernet connection).

There are times you have to adjust or change your connection settings, especially when using a laptop— just like in Windows.

How does NetworkManager work on Ubuntu Linux?
NetworkManager connects to Wi-Fi networks and automatically configures wired network connections when you plug in an ethernet cable.

The popup menu for NetworkManager appears when you click on the connection icon (either wired or wireless) in Ubuntu’s notification area.
Why is the Ethernet not detected in Ubuntu?
I am sorry for the poor explanation. Ubuntu is not detecting the the fact that it is connected (i.e., it says “Wire Unplugged”). The ethernet port lights are off.
