===== Setup =====

==== Enable ====
Tick to enable Ping Watchdog

==== IP Address To Ping ====
Select host address to ping to check for an active network connection, not all hosts will return pings. If required you can check manually from command line

<shell>
C:\Users\Dan>ping 8.8.8.8

Pinging 8.8.8.8 with 32 bytes of data:
Reply from 8.8.8.8: bytes=32 time=79ms TTL=55
Reply from 8.8.8.8: bytes=32 time=52ms TTL=55
Reply from 8.8.8.8: bytes=32 time=36ms TTL=55
Reply from 8.8.8.8: bytes=32 time=33ms TTL=55
</shell>

Note: The IP address 8.8.8.8 Google's public DNS. If your unsure which host to use this is a good default host.

==== Ping Interval ====
Frequency of network testing. Set this figure to low and you could flood your network with unnecessary traffic. Set this figure to high and it many take much longer to take the necessary action. Recommend the default of 3 minutes.

==== Startup Delay ====
Be careful with this setting. Setting this to low could create re-boot loop that your router may not be able to get out of. You should give you network time to settle down before checking for a connection. Recommend using the default of 240 seconds.

==== Failure ping count ====

Number of times to retry before confirming network failure

==== Action ====

On network failure confirmation take the one of the following actions

  * Reboot
  * WAN reconnect
  * Run Custom script

=== Reboot ===
Reboot the router. More time consuming but with a higher fix success rate 

=== WAN reconnect ===
Reset the network connects with out a reboot. Faster but lower fix success rate.

=== Run Custom script ===
