I'm running Ubuntu 16.04 on an Dell XPS 13 9350 (skylake)
Since the old kernel doesn't support the broadcom wireless card I updated to ubuntu 16.04, coming from 15.10. The 4.4 kernel should support the card. But it still doesn't work.
EDIT: It seems that only starting from the 4.4.1-1 kernel the broadcom wireless card is supported (see Arch Wiki).
So, iwconfig shows the card. Also lspci shows it.
If I type
sudo ip link set mywlan up ubuntu activates the card, but somehow recognizes it as an ethernet card. If I click the network Icon on the top right it says "Ethernet Network (Broadcom BCM4350 802.11ac Wireless Network Adapter)". And of course I don't get a connection to any wireless network. So... Any hints on how to change that? Any Ideas?

lspci -knn | grep Net -A2:
3a:00.0 Network controller : Broadcom Corporation BCM4350 802.11ac Wireless Network Adapter [14e4:43a3] (rev 08) Subsystem: Dell BCM4350 802.11ac Wireless Network Adapter [1028:0021] Kernel driver in use: brcmfmac Kernel modules: brcmfmac
Looks like the right driver is in use...
File properties of brcmfmac4350-pcie.bin:

EDIT (summary): So even with the 4.4.1 kernel ubuntu sometimes recognizes the card as a wifi-card, but most of the time as an ethernet card. For me it actually only recognized the card as a wifi-card once(!), this was at the first boot. This is probably a bug. If anyone has a reliable way to solve this issue I would be very thankful!
