Trouble seeing the internet on my mac

I’m running a 2017 macbook air using a usb and plasma, I cannot seem to see the internet nor able to connect to it through several different ways using the terminal. At some point I also got this error
“config ‘network’ does not exist”
any way I can fix this or do I just need to install it onto the system before I can connect to the internet

Hi @Blazmatic, and welcome!

Note:
Macs are notoriously full of problems for anything other than Apple. So getting it to work might bee a bumpy ride.
