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:
They represent activity happening on the router's Ethernet ports:
| ACTION | DESCRIPTION |
|---|---|
| LED turned ON | Operating as a 10/100 Mbps connection |
| LED turned OFF | No link established |
| LED blinking | Connection established and there is activity on this port (data being transferred) |
| LEDs light up and turn OFF in sequence from WAN port to LAN1 port | The router is in the bootloader menu state* |
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:

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.
