Pop! OS is one of the best Linux distro based on Ubuntu. It is simple, light-weight and easy to use.
I have an old laptop with core i-3 processor. I decided to install Pop! OS on it. So I downloaded the OS and made a bootable USB.
Installation was quick and easy. After installation when I tried to connect to my WiFi, I did not find any wireless adapter. I was very surprised as I did not find this type of issues long time.
Then I searched a bit and found that I need to install the wireless adapter driver manually. So I ran the following command in the terminal.
sudo apt install bcmwl-kernel-source
And it worked fine. So if you face this problem, just run the above command. You may need to reboot your computer.
best and simplest advice ever!! worked perfectly..
