RUT850 LEDs
This chapter provides explanations for LED actions on a RUT850 router.
Power LED
The power LED is located on the left corner of the front panel, to the left of the SIM holder:
It can perform two different actions:
| ACTION | DESCRIPTION |
|---|---|
| LED turned ON | Router is powered up |
| LED turned OFF | Router is not powered up |
WiFi LED
The WiFi LED is located on the router's front panel, between the reset button and the connection status LEDs:
It can perform two different actions:
| ACTION | DESCRIPTION |
|---|---|
| LED turned ON | WiFi is enabled |
| LED turned OFF | WiFi is disabled |
Connection status LEDs
The connection status LEDs are located near the right corner of the front panel, to the left of the signal strength indication LEDs:
The LEDs display the router's current connection state and network type among a few other things:
| ACTION | DESCRIPTION |
|---|---|
| 2G, 3G and 4G LEDs blinking every 1 sec | No SIM or bad PIN |
| Repeated blinking from 2G LED to 4G LED | SIM holder not inserted |
| 2G LED blinking every 1 sec | Connected 2G, no data session established |
| 3G LED blinking every 1 sec | Connected 3G, no data session established |
| 4G LED blinking every 1 sec | Connected 4G, no data session established |
| 2G LED turned ON | Connected 2G with data session |
| 3G LED turned ON | Connected 3G with data session |
| 4G LED turned ON | Connected 4G with data session |
| 2G LED blinking rapidly | Connected 2G with data session and data is being transferred |
| 3G LED blinking rapidly | Connected 3G with data session and data is being transferred |
| 4G LED blinking rapidly | Connected 4G with data session and data is being transferred |
Signal strength LEDs
The signal strength LEDs are located on the right corner of the front panel, to the right of the connection status LEDs:
Each lit up LED represents a different value of the router's current signal strength in RSSI:
| NO. OF LIT UP LEDs | SIGNAL STRENGTH VALUE |
|---|---|
| 0 | ≤ -111 dBm |
| 1 | -110 dBm to -97 dBm |
| 2 | -96 dBm to -82 dBm |
| 3 | -81 dBm to -67 dBm |
| 4 | -66 dBm to -52 dBm |
| 5 | ≥ -51 dBm |
The 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. When all 5 signal strength LEDs are lit up, they represent that 10 (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 5 LEDs will start blinking every 1 second. This signifies that the router has begun the reset.
