dell inspiron 15

The issue 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. Turns out that Dell Inspiron 15 has a Broadcom series of PCI wireless cards on board. 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).
