Public bug reported: I'd like to configure two wired connections: One to the outside world via DHCP, the other shared to other computers.
When attempting this, unpredictable behavior happens: the two wired connections are conflated with each other. Doing this with a wired connection and wireless works without problemms. Ubuntu desktop 20.04 LTS. I was able to get it to work after playing with netplan for a while and getting it almost right,giving up on that, deleting all network interfaces, and starting over. Configuration: Dell G7 laptop (one ethernet connector) is configured as IPv4 "shared to other computers" (A private network), IPv6 disabled. J5create USB 3.0 to gigabit adapter is configured as IPv4 Automatic (DHCP), IPv6 disabled. This didn't work initially -- clicking on the wired connector would sometimes bring up the USB adapter and vice versa. The approach that did work was to delete all networking and reenter from scratch. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901060 Title: Using gnome-control-center to configure two wired connections is unreliable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1901060/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
