It pointed me to this thread: “Before posting in Networking & Wireless” where I found a complete Broadcom guide in this thread: “How to install a driver for the Broadcom series of PCI wireless cards”. I was finally able to install the drivers for the Broadcom wireless card on my laptop after coming across this thread on the Ubuntu forums.

I was running Ubuntu 16.04 LTS at that time - I upgraded to 18.04 LTS (Bionic Beaver), the tips in this post would still work - and it didn’t support my WiFi card out of the box, I was almost certain it would be a driver issue even though I did some online search to get help but was guided by wrong directions by some of the online forums stating solutions like upgrading BIOS firmware, some Windows-related drivers updates and also some BIOS tweaks that worked for some people (probably they are not using Linux). Turns out that Dell Inspiron 15 has a Broadcom series of PCI wireless cards on board. Not so far ago, I had an issue with my Dell Inspiron 15 Series 3000 Laptop that I couldn’t connect to any WiFi network using the built-in wireless card and had to use a USB WiFi dongle.
