Welcome to TPG Community!
Did you connect your Wireless printer to your new NBN network? What is the error message that you are receiving?
May we also have the make and model of your Wireless printer?
Make sure that both devices are connected to the same wireless network in order for them to communicate with each other.
Feel free to post the screen shot of the error message.
Note: We the Wireless Printer may requires a dynamic IP address to work. Our NBN residential plan only offers Dynamic IP Address. For now, the only way to get a Static IP Address is by signing up with NBN Business.
