Modem connectivity troubleshooting

Use the following checklist when troubleshooting modem connectivity issues.

  1. Verify you are using the most recent version of NetCloud OS (NCOS). You can check your NCOS version from the ROUTERS page in NetCloud Manager(NCM). See the Cradlepoint Connect article How to update the NCOS of a Cradlepoint router for information on updating your device’s NCOS version.
  2. Ensure the SIM cards are inserted correctly. Refer to your router’s quick start guide for specific SIM-card installation instructions for your router. Find your router’s getting started guide on the Quick Start Guide Index page.
  3. Make sure the router’s antennas are securely connected.
  4. Ensure the router is oriented so its antennas receive the best cellular signal. See the Cradlepoint Connect article Modem Signal Strength and Signal Quality for more information on understanding the variables that affect signal strength.

If the preceding steps don’t resolve your modem connectivity issues, contact Cradlepoint Support or go to the Cradlepoint website.
