How to check modem status

Sometimes the modem may not work properly, or the unit may not be detecting the modem. Use the following diagnostic commands to help you troubleshoot issues with the modem.

diagnose sys modem {cmd | com | detect | history | external-modem| query| reset}

 

You should always run the following diagnose command after inserting the USB modem into the unit:

diagnose sys modem detect

 

You can view the modem configuration by using the get system modem command. You can also view the modem’s vendor identification as well as the custom product identification number from the information output from the get system modem command.

 

When there are connectivity issues, use the following to help you resolve them:

  • diag debug enable – activates the debug on the console
  • diag debug application modemd – dumps communication between the modem and the unit.
  • diag debug application ppp – dumps the PPP negotiating messages.
  • execute modem dial – displays modem debug output.

The modem diagnose output should not contain any error on the way to initializing. You should also verify the number that is used to dial with your ISP.
