You might want to monitor your Internet connectivity. The simplest way to do this is to run a regular task under Administration/Scheduler/Custom 1 e.g.
The besic command would be something like:
/bin/ping -q -c1 8.8.4.4
(8.8.4.4. being the a google DNS) which would cover the monitoring part without perform any action.
To link an action to success (&&) or failure (||) or both append the wanted condition + command
Examples:
/bin/ping -q -c1 8.8.4.4 || /sbin/service wan restart #if ping fails restart the wan
/bin/ping -q -c1 8.8.4.4 || /sbin/reboot # if ping fails reboot the device
/bin/ping -q -c1 8.8.4.4 && /usr/bin/logger “Internet available” || /usr/bin/logger “Internet unavailable” # successful ping will log “Internet Available” where ping failure logs “Internet unavailable”
etc
