All, I have a Dell XPS 13 series 9350, with eOS Loki ...
I have purchased a USB-C 3.0 Multi-Function Adapter, 3 USB ports and an Ethernet 10/100/1000 with the ax88179 chipset. The USB ports are working but the Ethernet port is not. When I plug the device in I get a window that says "disconnected Ethernet network" ... when I goto Network Settings "Wired Network" does not exist.
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Bus 003 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I do not see any Ethernet device (though from my research the ax88179 is part of the 4.4.0 kernal)
Any advice on how to troubleshoot?
