When moving a Verizon SIM card from a know working ES440 modem to test another ES440 modem hardware I can get into the modem via wireless ace and all data is correct and the Ip did show on tested hardware. However, with the modem to be tested I cannot access the equipment connected to the modem.
The network and signal LEDs are green. I can tell that the equipment software is talking the modem by the acitvity LED isflashing but the modem will not talk to controller.
I replace the SIM card back to the known working modem hardware and all communication works fine so I know our equipment works.


Topic moved to the correct section.


Can the title also be changed to something relevant :question: :exclamation:
