If you are not sure what model CradlePoint router you have, please click here.This article is based on the 5.0.0 firmware for Series 3 CradlePoint routers.Description: In areas where the 4G WiMAX signal is low, unavailable, and/or unstable the modem may bounce between a good 3G connection and an unstable4G WiMAX connection.  While the modem disconnects from 3G service and attempts the 4G WiMAX connection, the internet is not available.  By default, the CradlePoint router is set to have the modem connect to the highest speed network available.  This scenario is common in fringe 4G WiMAX coverage areas.  For cases such as this, it is advantageous to restrict a 3G/4G WiMAX modem to a 3G connection only. Directions:It is advised that your router has the most recent Firmware version loaded.  For instructions to check the router Firmware version see How to check Firmware version and How to Update Series 3 Firmware.

  3. In the WAN Interfaces section un-check the Enabled check box for the 4G WiMAX modem.                                   User-added image

 After disabling the 4G WiMAX connection, the CradlePoint router will ignore the 4G WiMAX modem connection and use the 3G modem connection. Note:  If WiMAX 4G signal becomes available or you change to a location where WiMAX 4G signal is available you may want to re-enable the WiMAX 4G connection by rechecking the Enable check box.
