Hi there and welcome
What exactly happens when you try to print?
First, can you confirm you know the password ***** your wifi network please?
no, I am not in Australia, but I do not see how that changes anything?
You need to connect it to your new wifi network, to do this, press on the tools icon (wrench / screwdriver) top right
Then press on wifi
choose Setup Wizard
Then select your wireless network and then enter in the Password.
Let me know how it goes please
ok, remove the power to your wifi router and printer and wait 10 minutes
Then connect the power to your wifi router and wait 5 minutes.
Then connect the power to your printer, try to connect it and tell me if it now connects please
thanks, ***** ***** me know the results
