Check the Signal Quality graph

  2. Click on Statistics, Graphs then on the Connections tab.

The Average Signal Quality on the quality_ltemodem graph should be 37% or higher:

If the Last Signal Quality is 0, check the 4G LTE antenna connections:

If the Average Signal Strength % is too low, reposition the 4G LTE antenna. If this doesn't work, try a third-party antenna with a longer cable and mount it in a different location (e.g. high on a pole).

If the problem persists, contact the support team.
