I've just installed CentOS 8 on my laptop using the minimal ISO. While it was able to connect to my apartment's Wi-Fi during installation, I am unable to get any connectivity from the terminal.

I'm connected to my router over the LAN so I'm able to install any packages as needed.
nmtui, while it allows me to edit my Wi-Fi connection, does not allow me to activate said connection. That is, the connection doesn't show up under "Activate a connection".
