I want to connect to two networks: one via ethernet (an intranet without internet access) and WiFi for wireless access.
Both networks use a different subnet. I've setup a separate ethernet connection in the network manager so it is never set as the default route.
But whenever I activate the intranet connection, the wireless connection disconnects.
If it matters I'm using nmtui for configuration (using i3wm) and on a Thinkpad with the external ethernet adapter.
Instructions here did not help: How to set up dual wired and wireless connections?
Have just logged in using default Ubuntu Desktop (not i3wm) and was able to activate both connections. Is there a different in using nmtui and the GUI on the desktop toolbar?
Using Ubuntu 19.04.
