(Apologies if slightly offtopic, couldn't find more appropriate place to ask)

I really miss having a built-in Ethernet port on the XPS 13. Its wireless adapter has been flaky lately (in various distributions, so problem must be hardware-related, not software), reminding me how much I appreciate a wired Ethernet option, not only for when wireless doesn't work, but also for when you don't want to use wireless and prefer a cabled connection for security reasons. So, I'm looking for suggestions about an Ethernet adapter for USB 3 that works on the XPS 13 under Ubuntu.

Everything else working nicely under 14.04 LTS (which also runs beautifully on my ancient 2008 XPS 1330).

Hoping there's a good Ethernet adapter out there for the XPS 13,
