Installation files

Caution

This Router App has been tested on a router with firmware version 6.3.10. After updating the router firmware to a higher version, check whether a newer version of the Router App has also been released and update it accordingly for compatibility.

Backup APN Introduction

Caution

This Router App is not installed on Advantech routers by default. See the Configuration Manual for instructions on how to upload a Router App to the router. For more information, refer to the Configuration Manual, chapter Customization — Router Apps.

The Backup APN Router App allows you to set a backup (secondary) APN for each available SIM slot. This Router App handles APN connection failures.

The left side of the web interface contains a menu with the following sections:

  • Status
  • Configuration
  • Information
  • Customization (which includes only the Return item to switch back to the router's web configuration pages).

The main menu of the Router App's web interface is shown in the figure below.

  • Use the Save Log button to save the system log to a connected computer (saved as a .log file).
  • Use the Save Report button to generate a detailed report (includes statistical data, routing tables, process tables, system log, and configuration, saved as a .txt file).

The system log defaults to 1000 lines. Once this limit is reached, a new file is created. After filling the second file, the first file is overwritten.
