Part of managing a 4G cellular wireless modem or router deployment is keeping up with firmware releases and understanding what each firmware release means to the stability/functionality of your 4G cellular platform. Recently it came to light that for the following CradlePoint routers, with GPS enabled, using the VZW LTE chipset, memory corruption could occur that would compromise performance of the routers. Read the important bulletin about this issue here.
What this bulletin does not say is why it is critical to make that update. The answer is that if the update is not performed, the CradlePoint Router can be bricked. The modem flash can become corrupt after a period of months if the GPS functionality is enabled. This can eventually cause the modem firmware to be overwritten on the device. When this happens, if the device is rebooted or power cycled, the modem will not come back up afterward. And since there is typically only a year warranty on CradlePoint devices, you really don’t want this to happen. CradlePoint urges that any organization using the following devices performs the radio firmware update:
List of LE-VZ products that could be affected:
- Cradlepoint AER2100LE-VZF (MC300LE-VZ)
- Cradlepoint ARC MBR1400LE-VZ
- Cradlepoint ARC CBA750B-LE-VZ (MC200LE-VZ)
