Dears, I just upgraded my XPS 13 to ubuntu 16.04 Now when i start my internal wireless adapter is recognized as a ethernet card instead of wireless card.
If I start the computer with my Dell DA200 connected, it does recognize then the adapter as ethernet and the internal adapter is properly recognized as wifi and works.
When it works, lspci yields 3a:00.0 Network controller: Broadcom Corporation BCM4350 802.11ac Wireless Network Adapter (rev 08)
