I am trying to connect my Arduino Uno to a router via Ethernet shield. There are lights that are also connected to the same router via Ethernet cable. I am wondering, if there is a way to use the Arduino to send a signal to the router, then to the port that the lights are connected to, to turn on/off the lights?
If so, where can I find more information? Which library/commands should I use?
Any help will be appreciated.
