will affect functions such as System Log entries and Firewall settings.

How to configure the Periodic Ping Reset Monitor

This facility is available by clicking on the "Services" menu followed by the "System Monitor" menu item on the right..
The Periodic Ping Reset Monitor configures the router to transmit controlled ping packets to 1 or 2 user specified IP addresses. Should the
router not receive responses to the pings, the router will reboot.
This works as follows:
A. After every "Periodic Ping Timer" configured interval, the router sends 3 consecutive pings to the "Destination Address".
B If all 3 pings fail the router sends 3 consecutive pings to the "Second Address".
C The router then sends 3 consecutive pings to the "Destination Address" and 3 consecutive pings to the "Second Address" every
"Periodic Ping Accelerated Timer" configured interval.
D. If all accelerated pings in step C above fail the number of times configured in "Fail Count", the router reboots.
E. If any ping succeeds the router returns to step A and does not reboot.
Note: The "Periodic Ping Timer" should never be set to a value less than 60 seconds; this is to allow the router time to reconnect to the cellular network following a reboot.
8�4�1 Periodic Ping Disabled
To disable the Periodic Ping Reset Monitor simply set to "Fail Count" 0
8�4�2 Periodic Ping Enabled
An Example Setup:
The setup below will ping 10.1.2.3 every 10 minutes, if it fails it then tries to ping 10.1.2.4, if that also fails it then accelerates the ping
attempts to once every 60 seconds and if 3 successive ping attempts at the one minute interval fails, the router will reboot.
NOTE:The traffic generated by the periodic ping feature is counted as chargeable usage, please keep this in mind when selecting how often to ping.
