XPS 13 9360 and DA200 adapter: power issue

Hello all, I'm configuring my new XPS 13 9360 with archlinux. I have an issue with a dell usb-c adapter (DA200 Rev A02, ethernet, usb, hdmi and vga adaptator). The ethernet connection is lost periodically and very often (every minute or so).

Is it a know problem (basically I can't use my new laptop at work since I don't have a wifi connection...)? Thanks.
