Hi @feru26,
Welcome to community!
You can change the WI-FI Name and Password by configuring the Wireless Settings of your equipment.
In order to configure the Wireless Settings, you can follow the steps below.
NBN Fibre to the Node Modem Guides
1. Connect to the network of your TPG supplied modem via WiFi or LAN then open your web browser (Google Chrome, Mozilla Firefox, Microsoft Edge, Safari,etc.).
2. Type in http://tplinkmodem.net and enter the default username and password, which is "admin".
3. Click on Wireless. Under the Basic Wireless Settings, you can change the Network Name (SSID) and password. Please make sure to use a different name for the 5Ghz Wireless Network to avoid issues in connecting to the WI-FI.
4. Click Save and reconnect your devices to the new Network Name using the new password.
Kind regards,
Mc
