There is an Ethernet cable that runs from a
server room to an
office. That cable is connected to a router. There are times when we need to reset that router and I will like to do that remotely. There is only one Ethernet cable that runs to the
office I wish there was one more.
I will like to place an arduino or raspberry pi at the
office that will be responsible for turning off and on the router with a relay.
I need to send a signal from the server room to the arduino located at the office.
I have tried using the NRFL01 and other radio signals but the distance is to far and the signal is lost because there is a lot of walls in between.
I want to use 2 of the existing Ethernet cables just like a Poe switch uses some off the wires to inject power. Instead of injecting power I will like to insert a signal. What cables can I use of the internet cable. I know very little about networking. Does it matter if it's a cat5/cat6? Can I do something like that?
