I have Ubuntu 18.04. Occasionally my laptop can not connect to WiFi. I tried a lot of answers but none works for me. Yesterday I tried to play a video I know that has sound but it was silent. Should I reinstall Ubuntu or there's another way to make things run? I tried 

sudo apt-get update
sudo apt-get upgrade

I have Broadcom for WiFi.

for audio system 

sudo apt install ubuntu-restricted-extras

then pavucontrol I didn't find it so I run sudo apt install pavucontrol

For WiFi sudo update-pciids sudo apt install firmware-b43-installer Then Reboot the laptop and every thing is fine.

I think there are two different (and independent) problems:

  • Wifi - it is important to use the correct proprietary driver for your model of Broadcom hardware. See this link,

    Installing Broadcom Wireless Drivers

  • Playing video - you probably need the correct codec for the sound-track, try again after installing the 'restricted extras'

    sudo apt update
sudo apt install ubuntu-restricted-extras

    It is also possible that you need to tweak the settings for the audio system with

    pavucontrol
