Connectivity issue

[Deambly]

Hi I recently got a new router. I used HP wizard on the printer to connect it online. All good there. 

I signed my computer on to the new network. All good there,

The problem when i try to connect the computer and printer it won't print. Firewall is off network sharing is on.

The problem I found is The network key on the HP smart app on my computer is still showingthe correct Network with the  the old password. How do I change that?

Thank you
