This article explains the firmware requirements for router activation and enrollment in Enterprise Cloud Manager (ECM).

To establish a successful connection to Enterprise Cloud Manager, a Cradlepoint router must meet the minimum firmware requirements:

  • Series 3: 4.3.2 minimum (6.0 recommended)
    • Note: MBR95 and CTR35 are not eligible for ECM service.
  • Series 2: 2.0.0 minimum (2.4.0 recommended)
  • Series 1: Not Supported


Configuration Difficulty: Intermediate

If the router is running an older firmware version, it will need to be updated before the router can be migrated or added to ECM. There are two possible update paths: immediate and incremental.

Method 1 - Immediate Update

Immediate update process is quicker, but carries greater risk of configuration settings being lost or copied over with errors. We highly recommend that this type of update is combined with a factory reset of the router. This method is ideal if the router is being setup for the first time, or if it is running a configuration that can be easily recreated.

  • Step 1: Factory reset the Cradlepoint router: please refer to Series 3 or Series 2 instructions.
  • Step 2: Upgrade the router's firmware to the latest available version. There are three methods of accomplishing this:
    • Updating Firmware within WiPipe Central
    • Manual firmware update: Series 3 and Series 2
    • Automatic firmware update. (Note: this option can only be used if the router has an active internet connection.)
      • Series 3: System Settings>System Software>Automatic (Internet)
      • Series 2: Tools>Firmware>Check Online Now for Latest Firmware Version

Method 2 - Incremental Update

If there is no physical access to the router, or the router is running a complex configuration that cannot be lost, the incremental update is the preferred method. The incremental, or stair-stepping, update process requires several smaller firmware updates which must be performed manually. The benefit of doing multiple smaller firmware update hops is that the router can copy the existing configuration far more efficiently with each hop.

Please refer to the WiPipe Central or the corresponding Series 3 and Series 2 articles for detailed instructions on updating router firmware.

Use the following sequence to update router firmware versions:

-> 3.2.4 -> 3.3.0 -> 3.4.1 -> 3.5.1 -> 3.6.3 -> 4.0.3 -> 4.2.1 -> 4.4.0 (4.3.3 for CBR4x0) -> 5.0.1 -> 5.2.3 -> 5.3.4 -> 5.4.1 -> 6.0.x

If the device is in between versions, start with the next version up. For instance, if the device is on 3.5.0, upgrade it to 3.5.1 first, then continue up the stairs.
