It has been noted on occasion that the apnname (access point name) value is not set when it is loaded from a config file, or where it does not restore to its previous value when the default config is restored.
There are two types of config files; "running" and "custom". This issue applies to both types. To resolve this issue, the apnwrite parameter must be set to “TRUE”.
The internal settings for a gateway include two distinct APN records: one in the LTE hardware module, and one in the CPE config.
They function as follows:
Note: Due to the differences between Default and Running settings, once the CPE clears the apnwrite field after setting the APN in the LTE module, the cleared apnwrite field is necessarily stored in the Running settings.
