I have installed ubuntu 19.04 and now I can’t connect to the internet using wifi. I can connect to the internet using tethering on my phone and a usb cord, but now I would like to install the realtek drivers to get wifi working correctly. Can someone please help with this? Instructions?
Open a terminal, type lspci and press enter
Look and see what it says for network controller that should tell you what type of network card you have in the computer.

How I found out what wireless card I have: https://help.ubuntu.com/stable/ubuntu-help/net-wireless-troubleshooting-hardware-check.html
I am using a PCI internal wireless adapter so that is what I looked up, but you can look up the information on the wireless method you are using by following the tutorial in the link.
