I've got a Dell XPS 13 9360 Developer Edition (Ubuntu 16.10). I'd like to use an ethernet adapter. I've bought a Dell Dock WD15 and a DA200 but I can't get the ethernet connection to work.

When I connect the USB-C cable, these devices show up in the lsusb list:

DA200:

Bus 004 Device 004: ID 0bda:8152 Realtek Semiconductor Corp.

WD 15:

Bus 004 Device 003: ID 0bda:8153 Realtek Semiconductor Corp.

How can I get this ethernet adapter working? Do I need to install extra drivers?

I've tested both devices with a Dell Latitude 7275 and Windows 10 and they're working fine.

Update: results from dmesg | grep -i r815:

  • The driver r8152 is included by default in Ubuntu 16.10. Please insert that device and check the log for informative messages: dmesg | grep -i r815 Next, edit your question to include the result. – chili555 Mar 29 '17 at 15:01
  • So far, so good! You have an ethernet interface enx00249b2352c9. Is there any sign of an ethernet connection in Network Manager? Any clues in the log? dmesg | grep enx In fact, both devices are driven by this same driver! – chili555 Mar 29 '17 at 16:01
  • No sign of an ethernetconnection. I've added the output from dmesg. – Stephan Vierkant Mar 29 '17 at 16:10
  • Let's dig deeper: cat /var/log/syslog | grep -e enx -e etwork | tail -n25 As the output will be lengthy, post the result here and give us the link: paste.ubuntu.com My next replies will be delayed about 2 1/2 hours. – chili555 Mar 29 '17 at 16:16
  • @chili555 paste.ubuntu.com/24275482. I reconnected the WD15 at 18:17:18. – Stephan Vierkant Mar 29 '17 at 16:19
