3.5 Services configuration
3.5.1 ICMP check (Ping Reboot)
In this section you can configure the ICMP check (Ping Reboot) function. This is a vital service which
is recommended in most remote installations. ICMP check configures the router to ping a specific
IP address or hostname at a set interval, if the IP address/hostname is unreachable for a set period,
the router will reboot either the whole device of the module (modem). The IP address is usually set
to a server which is guaranteed to be always online like google’s DNS servers at 8.8.8.8.
The mobile networks will disconnect devices at certain times, ordinarily a 4G device will reconnect
with no issue. However, there are occasions where a device will fail to reconnect to the local cell
tower and the device will need to be rebooted to reconnect. If the router is in a remote location this
will require an engineer to visit the site. The ICMP check will detect a disconnection from the internet
when it fails to ping google at 8.8.8.8. The router will auto-reboot and this will avoid many engineer
callouts.
We recommend using the pre-filled settings, just tick enable and save and apply to use this function.
