WiFi GUI not working

[AgentKerbal]

Hi thanks for the reply, though it hasn't worked, I'm getting a little confused whether this problem comes from the GUI or the network itself. I've been able to access the internet by changing my /etc/netplan/01-netcfg.yaml and doing

Code:

sudo netplan apply

. But even then the network icon on the panel is still indicating I'm not connected as well as the wifi part reading "Device not ready"
Again, any ideas are welcome
