New wifi, old settings. Primo seems unreachable

Have a recently(2 weeks ago) updated Volumio Primo, that runs stable and well. But now wifi has changed…new SSID and new code. I tried cabling Primo to my switch, but it never pops up on devices, and seems not to be getting an IP.

No hotspot available either. The unit behaves completely as if it is swtiched off, even though I power it on.
How can I contact my Primo ?

You could change the SSID and password to match the old wifi credentials and all devices will auto connect to the new modem/router.

Have you tried power off primo, attach cable and then power it on again?

I tried, power off, cable on to router, power on…but the device never came up on line devices on my network.

Changing SSID and passwords to old credentials seems excessive…but I’ll have a go later on…

Tried old wifi credentials on new wifi…no succes.

My Primo…(the older type) seems dead…?. Any way to tell wether it is in fact on, when any wifi/ethernet based interface is unable to connect?.
