If the Linux gateway is unable to communicate via mobile communication, the LAN communication will automatically take over. The following are some clarifications to the topic:
Whenever there is both a mobile and LAN communication, the mobile communication should be given priority. Observations have shown that the behavior in this manner is smoother.
It takes approximately one or two minutes for the Linux gateways to detect that there is no mobile connection. The communication automatically switches to LAN communication.
As soon as mobile communication is restored, the Linux gateway will be automatically switched from LAN to mobile communication.
