 +===== Connectivity Watchdog Notes =====
 +
 +This script is a custom one. Please note that there is also a setting in FreshTomato's [[basic-network|Network]] Web interface menu called "//Check Connections Every//". This feature performs similar functions, with some differences. It is not recommended that you use both this watchdog script and the //Check Connections Every //function at the same time. The two functions may interfere with each other, and conflicts might occur.
