Configuration
you want it to connect to private network “prn”. You can make sure that it connects to “prn” by enforcing the profile ID 1
in the LTE modem configuration, as illustrated below. This will ensure that modem always connects to “prn”.
Moreover, instead of letting the modem scan the environment for available networks to connect to, you can also force
the modem to always send network connection request with specific APN/authtype/username using the following
commands:
configure sys lte-modem
set apn/authtype/username
As illustrated below:
Upon receiving these settings changes, the modem reboots itself to refresh its configuration and re-initiate data
connection. The modem will temporarily disconnect during the reboot and shall reconnect once the reboot is completed.
Care must be taken to ensure that there is a wireless profile entry in the modem profile table
that matches with the enforced APNsettings. Otherwise, the modem will not be able to make
network connections because it cannot find a matching profile.
It is also possible to force the modem to dial with a certain wireless profile entry for connection using the following
commands:
configure sys lte-modem
set force-wireless-profile
As illustrated below:
This configuration must be used with the set apn command. Otherwise, it will not work.
