wifi setup by using terminal doesn't works

Hello, hackers.

I'm trying to set up wifi by terminal to study.

I have successully set up wifi using KDE Plasma,
but failed by terminal.

I mainly reffered to the following sites.
https://docs.slackware.com/slackbook:wifi

I set the files as follows.

/etc/wpa_supplicant.conf

But when I run the following command,
Code:# ping www.google.com
ping: unknown host www.google.comThis seems to have failed.

Could anyone please help me?
