I upgraded to Ubuntu 16.04 LTS (4.4.0-21-generic) and my wifi now works out of the box. I was using a usb-wifi since I bought my Lenovo Yoga 3 and I'm very happy because the builtin wifi card is much better. This bug is solved for me! However, I can't tell if the firmware I copied last month are used or not. 2016-04-22 19:14 GMT-04:00 Miles Krell
