@chili555: The point is that my Broadcom wifi device works with Linux
kernel 3.19.0-69-generic (modules wl + cfg80211). But the kernel modules
won't compile in kernel 4.4.0-36 which was installed automatically in
Ubuntu 14.04 LTS. In the description of bcmwl-kernel-source my wifi
chipset BCM4312
Affects me too. HP Compaq 615 (old laptop). Output of lspci (under linux image
3.19.0-68):
