Welcome to TPG Community!
Is your Android phone currently connected to the 2.4 Ghz WiFi connection or is it connected to the 5 Ghz WiFi connection? If it's currently on the 2.4 Ghz, are you able to connect to the 5 Ghz connection to check if the internet will work.
What are the troubleshooting that you've done so far?
I've checked the modem and it has the latest firmware.
