Ubuntu – Wifi doesn’t work on Macbook pro 15 of ubuntu 14.04 LTS

14.04broadcommacbook prowireless

Searched around and still cannot solve the wifi issue.

lspci -nn | grep 0280

shows

03:00.0 Network controller [0280]: Broadcom Corporation Device [14e4:43ba] (rev 01)

I installed bcmwl-kernel-source and also copied brcmfmac43602-prie.bin to /lib/firmware/brcm/ folder. Doesn't solve the issue. I tried removed the bcmwl-kernel-source package but still no wifi.
