RUT976 LEDs
This page contains information the different types of LEDs and their behaviour on a RUT976 device.
Power LED
The power LED is located on the bottom left corner of the front panel, just under the power connector.
It indicates whether the device is powered on or not.
| State | Description |
|---|---|
| LED turned on | Device is powered on. |
| LED turned off | Device is not powered on. |
WiFi band LEDs
The WiFi band LEDs are located at the bottom of the front panel of the device, to the left of the Ethernet ports.

They display whether a WiFi Access Point (AP) is active on a specific band.
| State | Description |
|---|---|
| 2.4 LED turned on. | At least one 2.4 GHz Access Point is running. |
| 2.4 LED turned off | No 2.4 GHz Access Points are running. |
| 5 LED turned on | At least one 5 GHz Access Point is running. |
| 5 LED turned off | No 5 GHz Access Points are running. |
WAN type LEDs
The WAN type LEDs are located at the top-right of the front panel.

They indicate which type of Internet connection is currently active.
| State | Description |
|---|---|
| SIM1 LED on | A mobile data connection on SIM1 is active. |
| SIM1 LED off | A mobile data connection on SIM1 is inactive. |
| SIM2 LED on | A mobile data connection on SIM2 is active. |
| SIM2 LED off | A mobile data connection on SIM2 is inactive. |
| WiFi LED on | A WiFi data connection (WiFi WAN) is active. |
| WiFi LED off | A WiFi data connection (WiFi WAN) is inactive. |
| ETH LED on | An Ethernet data connection (wired WAN) is active. |
| ETH LED off | An Ethernet data connection (wired WAN) is inactive. |
Ethernet port LEDs
There are two LEDs located at the top of each Ethernet port.
They provide information on the current states of the Ethernet ports. Each port has two LEDs:
- Orange - 10/100 Mbps connection
- Green- 1000 Mbps connection
Below is an explanation on the behaviours of green and orange LEDs.
| State | Description |
|---|---|
| LED on | A data connection on the port is operational (cable plugged in, end device visible, no data is being transferred). |
| LED off | No data connection on the port is operational (no cable, bad cable or end device not visible for some other reason (such as damaged network card). |
| LED blinking | Connection established and data is being transferred over this port. |
Mobile network type LEDs
The mobile network type LED is located on the bottom right corner of the front panel, near signal strength indication LEDs.
The LED displays the router's current connection state and network type among a few other things.
| Action | Description |
|---|---|
| Green and red blinking alternatively ever 500 ms | No SIM or bad PIN. |
| Green, red and orange blinking alternatively every 500 ms | Connecting to GSM. |
| Orange blinking every 1 sec | Connected 4G, no data session established. |
| Green blinking every 1 sec | Connected 5G, no data session established. |
| Orange lit and blinking rapidly while data is being transferred | Connected 4G with data session. |
| Green lit and blinking rapidly while data is being transferred | Connected 5G with data session. |
Mobile signal strength indication LEDs
The mobile signal strength indication LEDs are located on the bottom right corner of the front panel, to the right of the connection status LED.
The number of lit up LEDs represents a different mobile signal strength (RSSI) value in dBm.
| No. of lit up LEDs | Signal strength value |
|---|---|
| 0 | ≤ -111 dBm |
| 1 | -110 dBm to -82 dBm |
| 2 | -81 dBm to -52 dBm |
| 3 | ≥ -51 dBm |
The Mobile signal strength LEDs can also be used as a time indicator for holding the reset button. When you press and hold the reset button, if there is a User's default configuration configured on the device, you have to hold it pressed for 6 seconds (by default) to initiate a User's default configuration reset and 12 seconds (by default) to initiate a Factory reset. Otherwise, it is only necessary to hold the reset button for 6 seconds to trigger a Factory reset. If the button was held down longer than 20 seconds (by default) no action will be taken.
While holding the reset button each lit up signal strength LED indicate that a period of two seconds has passed. In case with RUT976, when all 3 Mobile signal strength LEDs are lit up, they represent that 6 (LED number multiplied by 2) seconds have passed since you pressed down on the reset button.
After releasing the button at one of the reset periods, all 3 LEDs will start blinking every 1 second. This signifies that the router has begun the reset.
