The network watchdog is also part of the monitoring process. If none of the WAN
interfaces are available, the network watchdog, if configured, reboots the gateway
after the configured period with no WAN connection. If you have Accelerated
Interface Scan enabled, ALEOS attempts to regain connectivity on one of the
available interfaces until the reboot occurs.
As a final strategy, if the network watchdog fails to re-establish connectivity, there
is a backoff mechanism whereby the gateway waits for 1 hour before starting the
network watchdog mechanism again to prevent frequent rebooting.
To configure these options, see the following sections:

What Happens
If the gateway is able to communicate with the router and
•
receive an IP address, it assumes it has WAN connectivity.
The router's connection to the WAN is not verified.
If the gateway is unable to establish communication with the
•
router (i.e. no IP address, cable unplugged) it attempts to
connect to the cellular network.
If the gateway receives a response to a ping sent over the
•
Ethernet WAN network, it uses the Ethernet WAN interface.
If the gateway does not receive a response to a ping sent
•
over the Ethernet WAN, it attempts to connect to the cellular
network.
