If there are two bars or less, the signal is too weak to ensure a good level of service. If there are three or four bars, the signal quality is ok.
If you press the screen toggle button on the right side:
•    If UL1 is >= -13db: the LoRa network is good
•    If -13db > UL1 > -20db: the LoRa network is weak and a good level of service is not guaranteed. In this case, we recommend using the cable extender to improve the signal quality level
•    If UL1 < -20db or there is no result (--): the LoRa network is not available
