Jio AirFiber LED Lights Meaning: Red, Green & Blue Color Codes Explained

You just installed Jio AirFiber. You see a Green light, then it turns Blue, and sometimes it blinks Red.

What is your router trying to tell you?

Unlike the old JioFiber routers which had many icons, the new Jio AirFiber (5G) box has a single LED ring that changes color to communicate its status.

Below is the complete Color Code Cheat Sheet to understand what your device is doing, and how to fix it if the light turns Red.

Jio AirFiber LED Color Code Table (The Cheat Sheet)

Save this table. It explains every possible status.

LED Color	Light Behavior	What It Means	Action Required
🟢 Green	Solid (Steady)	Online & Healthy	None. Your internet is working perfectly.
🟢 Green	Blinking	Booting Up	Wait 2 minutes. The device is restarting.
🔵 Blue	Solid (Steady)	Ready / Standby	It is connected to the Roof Unit (ODU) but waiting for an IP address.
🔵 Blue	Blinking	Pairing / Updating	Do not turn off. It is downloading a Firmware Update.
🔴 Red	Blinking (Slow)	Weak Signal	Internet works, but speed is low. Move the box closer to a window.
🔴 Red	Blinking (Fast)	No Signal	Critical Error. It cannot find the Roof Unit. Check cables.
🔴 Red	Solid (Steady)	Hardware Failure	The device has overheated or crashed. Needs a Hard Reset.

Detailed Meanings & Fixes

1. The “Blinking Red” Light (Most Common Issue)

If your light is flashing Red fast, your Indoor Unit (IDU) has lost connection with the Outdoor Unit (ODU).

Cause: Loose cable, heavy rain blocking 5G signals, or the Outdoor Unit has lost power.
The Fix:
1. Check the POE Adapter (The power brick). Ensure the cable going to the roof is plugged into the port marked “To ODU” (Outdoor Unit).
2. Perform a Power Cycle: Turn off the switch, unplug for 5 minutes, and plug back in.

2. The “Solid Blue” Light (The Stuck Glitch)

Sometimes the light stays Solid Blue but you have no internet.

Meaning: The device is physically connected, but Jio’s server hasn’t assigned it an IP address yet.
The Fix: This is often a “Authentication Hang.”
- Open the MyJio App.
- Go to Fiber > Diagnostics.
- Click “Re-Authenticate” or “Troubleshoot.”

3. The “Blinking Blue” Light (Do Not Touch)

If the light is Pulsing Blue (fading in and out), it is downloading a critical software update.

Warning: If you unplug the power during a Blue Blink, you might “brick” the router (corrupt the software). Wait at least 15 minutes before touching it.

How to “Hard Reset” the Light (If Stuck on Red)

If the light is Solid Red and won’t change even after a restart, you need a factory reset.

Locate the tiny Reset Hole on the back of the white box (near the LAN ports).
Use a SIM Ejector tool or paperclip.
Press and Hold for 10 seconds until the light flashes Purple or Off.
Release and wait 5 minutes for it to reboot.
