I have some LTE connectivity issues that need to get assistance from here! Thanks in advance for any help.
I have an RV50X that was running properly in the field. Due to the power consumption is too high for our small solar system, I set RV50X to “Timed Standby” mode (Only wake up 5 minutes per hour) to reduce the power consumption. After it properly runs for several months, the modem suddenly cannot get any cell connectivity (Carrier: Verizon). I have checked the SIM card in another RV50 and it worked properly. I tried to update the AirLink and Radio Firmware several times but no luck.
I have checked the SIM card slot1 and slot2, they both look good not damage.
The attached picture is what I saw in the AirLink. Under the firmware update, the radio module identifier is NOTSET, and the radio Firmware Version is RMNode, which seems abnormal.
And the Radio Module Firmware Tab is also shown a warning message as in the picture and non of the firmware was active… I tried to activated VERIZON several times also tried to upgrade to a new version of the firmware. None of the methods helped.
Any help would be greatly appreciated!
