ThinkPad LTE Troubleshooting

Assure Ethernet is disconnected, Wifi turned off, and LTE or Cellular turned on.

NMU LTE connected? See Connecting to NMU LTE

    YES, Jump to “Yes, Proceed”.

    NO, Verify NMULTE APN settings for Thinkpads

           Connected after verifying NMULTE APN settings and reboot?

               YES, Jump to “Yes, Proceed”.

               NO, (should be a link to a new page with detailed instructions) Delete the LTE adapter in device manager (found under Network adapters as Sierra Wireless), reboot, and verify NMULTE APN settings.

                      If still not connecting go to CONTACT THE HELPDESK


Yes, Proceed

    Go to, What IP address is listed?

        If IP shows 10.x.x.x, it is not registered, register it using your NMU UserID and password.

        If IP is 35.x.x.x (note the IP address), your device is registered.

        If fails to connect to register page and/or has no IP address, check computer's IP address. (Open CMD Prompt, type in ipconfig /all and check the IPv4 address. If it is 192.168.x.x, proceed to CONTACT THE HELPDESK, otherwise, troubleshoot network connections with device and start troubleshooting again.)
