Troubleshooting
The following issues may occur when swapping, upgrading or deleting PRI and firmware files.
Your modem does not come on-line after an upgrade:
Reboot your router using the reboot command or,
Shutdown the 'wwan0' interface using the shutdown command and no shutdown command to
bring it up again.
Preferred firmware version does not match the current firmware version. For example, an extract
from the show 5g tech firmware command:
AT!IMPREF
Preferred fw version:
Preferred carrier name:
Preferred config name:
Preferred subpri index:
Current fw version:
Current carrier name:
Current config name:
Current subpri index:
If your modem upgrade fails with the failed upgrade problem below, reboot your router using the
reboot command. The upgrade should now work.

Case sensitive carrier names
Sierra Wireless usually uses capital letters for carrier names. For example, version 3 uses
03.04.03.00_TELSTRA and version 2 uses 02.08.01.00_Telstra. The carrier name is not case
sensitive for the carrier command but it is for the platform commands.
The PRI carrier files overwrite the older version when upgrading. If you do come across a differ-
ence such as in the output below, delete the lower case version to avoid confusion. Use the
command platform 5g delete pri telstra. See the extract below from the show 5g tech firm-
ware command:
