While one installs a fresh Ubuntu OS in any machine,typically he finds an initial deterrent as the Wifi adapter is not found installed.This post gives a step by step direction on how and what to do,to get the Wifi working....and this happens since the same is not installed by default.
Since the PCI.ID initials for any Wifi broadcom adapter is prefixed 14e4,thus first we need to find the exact PCI.ID

Type
lspci -nn -d 14e4:
Once you get the PCI.ID,you just need to ref the following table and find the corresponding driver to be installed.In our case is 14e4:4365 rev 01,so we choos the corresponding bcmwl-kernel-source
PCI.ID 14.04 LTS 16.04+
