Hi @Newbie2020
Welcome to TPG Community!
We tried to locate your account using your community details to no avail.
You may try to turn Off and On the WLAN/WiFi via the button on the modem or else, have your Laptop connected via Wired/Ethernet cable in order to access the modem page to change the settings.
If it's still not working, then the final step is to reset the modem to its default.
Let us know how it goes.
