There's something wrong going on here. I first reported this issue as a 'linux' bug, based on a hasty reading of documentation. I never finished that report, so I expect that to be incomplete.
Shortly afterwards I re-reported it as a probable NetworkManager issue. It seems that these two issues have got the same #number. Any confusion about whether this is confirmed or not is, I'm afraid of your own making. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1796355 Title: USB-C ValueLine network adapter fails to connect Status in linux package in Ubuntu: Incomplete Status in network-manager package in Ubuntu: New Bug description: The adapter I'm trying to use using is a 'Valueline' USB-C adapter, with no external identifying information. lsusb lists it as Bus 004 Device 022: ID 0bda:8153 Realtek Semiconductor Corp. It works fine on a Windows 10 system (same hardware platform), where it's identified as a 10/100/1000 Realtek adapter. When I connect it to my system (Asus Zenbook UX490UA) internal lights go on, but no connection is produced. The network icon (upper right) is shown briefly, then disappears, the is show, then disappears. After some time it seems to give up.
