I'm using TRB-140 with a static IP 4G sim card. I obtain an abnormal ping who do not permtit us to use the TRB-140 in good conditions. I have tried to upgrade the firmware, here my latest version:
An example of ping below with 4G(LTE) connexion at -65dBm:
I have tried in different places(differents 4G relay antenna) with 2 differents SIM card and it's the same issue. My provider have say to me to see with the gateway manufacturer. Is there anything to check or configure on the gateway for having lower ping, stable and at tens of ms?
Thanks by advance for your help.
