Hi there and welcome
Can you tell me please, what goes wrong when you try to connect the printer to your new wireless network? What is the error that you get?
Did you go through the installation again to install it on your new wireless network as this needs to be done
Please let me know.
yes. The problem is the printer is linked to your old wireless network, so you need to do a full installation of the printer and join it to your new network.
You install it just like you did when you first received it.
Once done, its on your new network, the computer has the new details to connect to it, so does the printer and you can print wirelessly again.
Let me know the results please.
