I installed 16.04 as a double boot on my 2011 Mac Mini and all seemed to work - until I tried to connect to my network (wired and wireless). I get the message that the connection is established after quite a while, but no IPv4 is assigned, and I don't see any eth0 interface (in /dev). The weirdest thing is that I can get a connection working with a guest login on my router. That connection is open, if I use the encrypted wireless connection to my network I don't get an IPv4 (no inet line in ifconfig). Do I need proprietary drivers for the network interfaces, and if so, which ones might that be? Thanks - Merlin

  • What is the output of: sudo lshw -C network – ActionParsnip Jun 28 '16 at 7:52
  • I just got one step further: The command sudo apt-get install firmware-linux-nonfree broadcom-sta-dkms and a reboot got my wireless to work now, so I can at least connect to my local network through the wireless adapter. Now I still have to find a solution to get the wired gigibit adapter to work - there just MUST be a way - hopefully there is a kind soul out there who knows :-) – Merlin Silk Jun 29 '16 at 6:56
  • oops - ActionParsnip - didn't see that question of the lshw output - here it is (that is with the wireless already working: *-network description: Ethernet interface product: NetXtreme BCM57765 Gigabit Ethernet PCIe vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:02:00.0 logical name: enp2s0f0 version: 10 serial: 3c:07:54:0c:52:24 size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz – Merlin Silk Jun 29 '16 at 21:33
