Accidentally changed network settings

I have the following problem: I have accidentally changed the settings:

Network settings


Wired network -> automatic ip -> OFF

And the wireless network = Off

I have not entered anything else and leave everything as standard.
Now I can no longer connect and I no longer see Volumio in my router.
Is this recoverable?

I have try this because I often lose connection with the android app. I get a: search device.

Can you see the Volumio hotspot (not sure whether “wireless off” affects this)?
