Monitoring the state of a cellular connection

If a device does not have a modem, the use of a cellular connection and configuration of cellular connection settings are unavailable.

You can track the state of the Kaspersky IoT Secure Gateway 1000 cellular connection under Settings → Network → Modem. The Modem settings area displays the following information about the state of the cellular connection:

• Modem status – displays the state of the Kaspersky IoT Secure Gateway 1000 cellular connection. The following values are available for this setting:
  • A gray icon means that the modem is currently not available for use.
  • A green icon means that the modem is connected to the cellular network provider.

    If you want to use the modem as the main communication channel, you need to enable the use of a cellular connection for Kaspersky IoT Secure Gateway 1000.

  • A red icon means that there is no connection between the modem and the cellular network provider.
• Signal quality – displays the quality of the cellular connection between Kaspersky IoT Secure Gateway 1000 and the external network.

  The number of lines denotes the signal quality of the cellular communication network that the device is connected to. As the signal quality decreases, the number of bars is reduced.

In the Modem DNS server addresses block, you can view information about the IP addresses of the primary and secondary DNS servers of the modem.

If there is no cellular connection, you must verify that the following conditions are met:

• The SIM card used in the modem is valid and has an active plan that supports an Internet connection through the modem.
• The selected modem profile matches the utilized SIM card.
• The modem is available for use (a green icon is displayed in the Modem settings block).

  If the modem is not available for use (a gray or red icon is displayed in the Modem settings block), you must restart Kaspersky IoT Secure Gateway 1000 and re-check whether the modem is available for use after the restart. Devices that access the Internet through Kaspersky IoT Secure Gateway 1000 must obtain the internal network settings through the DHCP server of Kaspersky IoT Secure Gateway 1000. The relevant addresses of DNS servers from cellular network providers will be received together with these settings.
