I have just installed Ubuntu 16.04.1 LTS on my Desktop PC that has a built in wireless adapter in the motherboard (Broadcom 802.11ac 14e4:43b1).
Right now I do not have the installation disk nor access to ethernet so the below post did not work for me. Installing Broadcom Wireless Drivers
I found this drivers https://launchpad.net/ubuntu/+source/bcmwl/184.108.40.206+bdcom-0ubuntu7
and i am wondering how do i install this offline.
Please help, I am a complete beginner and would be really helpful if you can elaborate.
