Welcome to Globe Community.
Before we proceed with the troubleshooting, may I ask something first?
1. What is your Router / Wifi model?
2. Define not working. Wifi is on at interface but do not transmit signal? Wifi is off? Wifi with signal but no connection to internet? etc etc
3. Have you restarted your modem?
4. Are you using any third party devices. i.e Wifi Router (not provided by globe)
