|
Solid yellow (or orange) Initializing or starting up. |
||
|
Flashing yellow (or orange)
In the process of connecting to the cellular network and to a device on its ETH2 port. |
|
Flashing white
ETH2 port connection established and in the process of connecting to the cellular network. |

|
Flashing green
Connected to 2G or 3G1 and is in the process of connecting to any device on its ETH2 port, or nothing is connected to the port. |
|
Solid green
Connected to 2G or 3G and also has a device linked to its ETH2 port. |
|
Flashing blue
Connected to 4G LTE and in the process of connecting to a device on its ETH2 port. |
|

1. Or an unknown type of cellular network.
Signal quality indicators
LEDs labeled 1 through 5 Indicate the cellular service quality level.
| Signal bars | Weighted dBm | Signal strength % | Quality |
|---|---|---|---|
|
-113 to -99 | 0% to 23% | Bad |
|
|
-98 to -87 | 24% to 42% |
Marginal |
|
|
-86 to -76 | 43% to 61% | OK |
|
|
-75 to -64 | 62% to 80% | Good |
|
|
-63 to -51 | 81% to 100% | Excellent |
The weighted dBm measurements are negative numbers, meaning values closer to zero denote a larger number. For example, a -85 is a better signal than -90.
Note See Cellular signal quality explained for more information regarding how signal strength is calculated and subsequently displayed via the LED indicators.
Ethernet Link and Activity
The LEDs on the WAN/ETH1 and ETH2 ports indicate that the Ethernet network interface is up and there is activity on the network interface.
Left LED (on top of port connector)
- Off: No Ethernet link detected.
- Solid amber: Ethernet link detected.
- Blinking amber: Indicates Ethernet traffic.
Right LED (on top of port connector)
- Off: No Ethernet link detected.
- Solid green: 10/100 Mbps link detected.
