I am using a Dell laptop Intel Core 2 Duo CPU with 4G RAM and wiped Windows Vista off it to replace it with Ubuntu 18.04. I installed the OS tonight and the wifi light went off and no wifi recognition panel appears when I log on (I am typing this on my wifi connected windows PC). When I use an ethernet cable firefox states 'we can't connect to the server at...' so it's like I don't have wired or wifi access on the laptop at all, although it worked before I installed Ubuntu. I tried to update the Broadcom drivers in additional drivers and selecting apply changes didn't work, it wouldn't update at all. So basically - wifi worked on this laptop pre-Ubuntu (eg - yesterday) and now doesn't work at all, nor does wireless. I am a complete noob at linux and my 'restore new life to old laptop' hasn't got off to a great start! Any help appreciated.

Connect to the internet using your phone. You can connect almost any phone by USB and use it as a modem.

Then run in a terminal

sudo apt update
sudo apt install bcmwl-kernel-source

With the 18.04 Ubuntu version it is not very straight forward to install Broadcom drivers offline.
