What is the easiest way to add a second LAN port to a laptop with Ubuntu and 1 LAN port?

A switch.

Should be under Ubuntu Plug And Play and need no additional drivers.

a router

Linux Hase

And do not need additional drivers

what is that supposed to mean? Of course, for other hardware, another module (you call it a driver) is needed. If you get out which chip is used for the "built-in LAN", then the extra could be "treated" with it. Since the new but only as a USB-LAN stick in the laptop is possible, it may u.U. But there are differences.
I do not see a reason for such a condition. Find a stick that is proven to be suitable for Linux and ready.

Do you want to use the laptop as a router in another LAN?
