Manual Modem Firmware Upgrade

Upgrading the modem firmware regularly is important to keep a secure and reliable internet connection. This can be done manually or through ECM, this document focuses on manual upgrade.

Please note that this only upgrades the modem firmware, to upgrade the router firmware click here. To connect with this modem you must also have an activated SIM from the carrier in the device. During the upgrade process the modem will restart: the router may go offline for a few minutes if this modem is it's primary WAN connection.

Although a single Cradlepoint modem may have two SIM card slots (e.g., IBR1100 integrated modem), it is one modem module and can only have one modem firmware version, and therefore only one carrier at a time. The exception is that the AER 2100 could have two distinct integrated MC400 modems, each with two SIM slots. So while each modem by itself can only have one firmware version, the AER 2100 can support two integrated modems - on distinct carriers- simultaneously.

  • You may also need to make sure you are trying to use the same interface and SIM slot. Some products contain two SIM slots, and therefore there are two “Internal LPE” interfaces displayed in Connection Manager. If your active SIM is in slot 1, the “Internal LPE (SIM1)" will be the one to connect with that SIM; SIM slot 2 will correspond to “Internal LPE (SIM2)".
