Searched around and still cannot solve the wifi issue.
lspci -nn | grep 0280
03:00.0 Network controller : Broadcom Corporation Device [14e4:43ba] (rev 01)
bcmwl-kernel-source and also copied
/lib/firmware/brcm/ folder. Doesn't solve the issue. I tried removed the
bcmwl-kernel-source package but still no wifi.
