Series 3: How do I update the firmware of a CradlePoint router?

If you are unsure of CradlePoint Series or Model number, please click here

Symptom:

Inability to connect to the Internet with a supported modem through a Series 3 CradlePoint router.

Cause:

Outdated Firmware.

Conceptual Plan:  Since an Internet connection cannot be established through the router, the modem will need to be connected directly to the computer in order access www.cradlepoint.com and obtain the correct firmware files.  After saving the necessary firmware files on your computer the modem will need to be removed from the computer, and the CradlePoint router connected.  To connect a computer to the router and update firmware, no internet connection is required, only a connection between the computer and router. Once the router is connected to the computer, the files will be uploaded to the router and installed.

  1. Turn off your CradlePoint router.
  2. Connect your modem to your computer and establish an internet connection utilizing your carrier instructions.
  3. Open your web browser (Internet Explorer, Chrome, Firefox, Safari, etc.) and type http://cradlepoint.com/firmware into the main address bar.                                                               User-added image
