Fresh install 16.04 on Lenovo U41, neither Ethernet nor WiFi

Hi all,

my first post in this forum - in the last years of using Ubuntu, it has been of great help, and I've been able to solve any problems I've had with your posts.
I recently got a Lenovo U41 and installed 16.04, but neither Etheet nor WiFi are working. Plugging in the network cable results in the WiFi-Symbol looking like it would coect, but not coecting; furthermore, the existence of the cable is recognized, but I can't coect to the Inteet. The notebook had OpenSuse installed before, where the coection was working flawlessly.
Since there is no cable coection possible, I can't install any Broadcom (BDM4352 802.11ac, [14e4:43b1] (rev 03)) drivers - I've tried several things, but I just don't really know where to start. How can I get this thing to work? I'm currently coected on another machine, posting from there.
Please see the wireless-info script output that I have attached. I appreciate any help. Thank you.
