Reset Router when Internet lost

[managementboy]

I have my LogicMachine remotely behind a router. Sometimes the router looses the Internet for a minute and for unknown reasons the build in VPN does not restart. I have hooked up one KNX actor to the power of the router. Once a day I do I scripted on/off. That has solved the problem temporarily.

Question: how would I go about creating a script that checks if the Internet is available from the LM and if not sends an "off" and after a minute an "on" to the knx actor?

cheers!!!
