I have 2 flexy 205’s installed(soon to be more) and they have the 4g cellular cards in them. Both of them have a strong cellular signal, but for some reason they randomly lose connection. In the ecatcher program it still shows I am connected, but I get booted offline with my plc, and am no longer able to even ping my devices. Sometimes if I just wait a minute or so I can re-establish a connection to my device, sometimes it is 5 minutes. It is very frustrating. Do you have any suggestions to keep me from having this problem?
