Hardware being used-
- Routerboard 433UAH
- Franklin Wireless U770 Tri-Band USB modem (Sprint) Note- Configured only to work in 3G mode, WiMax and LTE are disabled at this time. USB modem has also had Auto Enable turned on.
- Novatel Wireless USB760 (Verizon) Note- Service deactivated but previously working just fine.
I recently had to switch from a Verizon 3G USB modem to a Tri-Band USB modem from Sprint. I still have the Verizon modem and when I connect it to the USB port on the RB433UAH, the PPP-Client Status changes as follows and repeats itself-
Resetting link
Initializing modem
Dialing out
Obviously the Status never changes to Connected because the Verizon service has been deactivated. What I am looking for is, what changes are required to make the routerboard establish a connection using the new Tri-Band modem from Sprint in 3G mode based on the Sprint network’s requirements? When the Verizon USB modem is disconnected from the routerboard and the Sprint modem is connected to the USB port instead, the PPP-Client Status does not change at all and shows Disconnected unless I activate Dial on Demand and then the Status will change to Running followed by Waiting for packets and remains there indefinitely. Below is my configuration for the PPP-Client when the Verizon 3G modem was being used.

Any help is greatly appreciated.
