ThinkPad LTE Troubleshooting

This page is a part of a series of pages for LTE troubleshooting. If you haven't already done so, please start the LTE troubleshooting process by going to the LTE Troubleshooting (Start Here) page.

NMU LTE is not installed in NMU issued ThinkPads by default. If you were issued a NMU ThinkPad, you can get NMU LTE network and SIM cards installed at no charge so the computer can access the NMU LTE network. If you have not already done so, please stop at the Helpdesk to get a work order for the LTE hardware to be installed. 

Assure Ethernet is disconnected, Wifi turned off, and LTE or Cellular are turned on. See Connecting to NMU LTE

NMU LTE connected?

    YES, Jump to “Verify Network Registration”.

    NO, Verify NMULTE APN settings for Thinkpads

           Connected after verifying NMULTE APN settings and a restart?

               YES, Jump to “Verify Network Registration”.

               NO, then Delete the LTE adapter and Restart the computer  

                      Check if NMU LTE is now working by following the steps at  Connecting to NMU LTE

                              NMU LTE connected?

Verify Network Registration

    Go to, What current IP address is listed?

        If it is 10.x.x.x, your device is not registered. Register it using your NMU UserID and password. You should be able to access the Internet within 15 minutes.

        If it is 35.x.x.x (note the IP address), your device is registered. HURRAY! You should be able to access the Internet.
