I installed ubuntu 16.04 on my dell xps 15.
Unfortunately wlan does not work any more.
no wlan is offered in the system settings, and
and no wlan device is in the /etc/network/interfaces.
root at lappi:/home/robert# cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
iface lo inet loopback
this is what lspci displays:
