To address the frequent disruptions with your Jio Fiber connection, first power‐cycle your ONT device and ensure all cables are firmly connected. Open the MyJio app, go to Support → Fiber → Report Issue to log a ticket.
You may also call JioFiber helpline at 1800-896-999 (24×7) for immediate assistance. If your issue persists beyond 48 hours, escalate by emailing or filing a grievance on the Jio Consumer Grievance Portal with your ticket ID.
