Hi @Lilla_boh!
Thank you for reaching out to the community. I'm sorry to hear that you can't access your device due to a network change. I'll be more than glad to help you with your device. Before we start, could you please reply to the following questions:
- What type of device do you have?
- Do you use the Google Home App or the Nest app?
- Have you tried some troubleshooting?
In the meantime, you can take a look at the following article: Factory reset Google Nest or Home speakers or displays.
I’ll be waiting for your reply.

Derick.
