Summary

This article describes the steps necessary to address the following issue: even though the cellular modem works correctly when plugged directly into a computer, it displays "Suspended" or "CPPM failed: Carrier Reject" as its status and will not establish an internet connection when plugged into a Series 3 Cradlepoint router.

Some cellular networks use technology that requires an Access Point Name (APN) to be configured on the modem to successfully establish an internet connection. The connection software that most cellular providers make available for use with their products with a computer normally includes the APN configuration by default, but the Cradlepoint router needs to be manually configured. This is very common for static IP cellular data accounts. Cradlepoint recommends automatically getting the APN using Over The Air (OTA) programming first before manually configuring the APN.


Configuration

Configuration Difficulty: Intermediate
  • Step 1: Log into the router's NCOS Page. For help with logging in please click here.

  • Step 7: Pull down the Access Point Configuration menu, and choose the Default Override option.
    • NOTE: The Default Override option may not be available on all modems. Cradlepoint recommends using the OTA programming for getting the correct APN.

  • Step 8: Enter the APN provided by your cellular carrier and click Save.
    • NOTE: A list of common APNs is displayed within the help panel, and some additional options can be found here. If you are not sure which APN you should use, please contact your carrier.

  • Step 9: Click OK in the confirmation dialog. You should see a message indicating that the settings have been applied.
    • NOTE: After a new configuration has been submitted, the modem will reboot itself which will cause it to disappear briefly from the WAN Interfaces list before it tries to connect again.

Troubleshooting

Submit Button is Greyed Out

If you've filled in the correct APN, but cannot click the Submit button to apply the change, it is possible your browser is misreading other fields and automatically filling them in with bogus values the router cannot accept.

  • Try using another browser
  • Try clearing your browser's cache

There is no Access Point Configuration Section

If your SIM/APN/Auth tab looks like the following screenshot, or it does not do anything at all underneath the Authentication Protocol fields, it could be because the browser is misrendering the page.

If the problem persists, it could be an issue with the configuration of the router itself. To restore the configuration, we'll need to return the modem to the default

  • Step 1: Click on the Connection Manager tab on the left and click on the modem to highlight it.
  • Step 2: Click on the Control button above.
    • Note: The modem Unique ID or UID can be found by clicking on it once within the WAN Interfaces list at the top of the page.
  • Step 3: Select just this rule and click the Remove button.
    • Note: This will also remove other custom settings, such as loadbalancing, forced modem connection mode, failover and failback. These will need to be reconfigured again.
  • Step 4: The modem should briefly disappear from the WAN Interfaces list. If it does not, reboot the router.
  • Step 5: Edit the modem again within the WAN Interfaces list, set the APN, and reconfigure any lost settings.

Modem Is Still Not Connecting

If you have set the APN, but the modem is still getting a "Suspended" error message, try the following:

  • Check with your cellular provider to verify what the correct APN should be. In some cases, especially when you have signed up for a static IP, you might be provided an APN before it actually becomes active on your account.
  • Check the list of Advanced Configuration Rules and verify that the rule that matches your modem's Unique ID appears below the LTE Defaults rule. If it doesn't, you will need to reorder them to make sure the default rule doesn't overwrite the more specific APN settings.
  • Refer to this article for additional troubleshooting steps.
