Say I need to shut off internet access in my home to prevent my teen from having the temptation to play multiplayer games at all hours. I'm thinking that I could insert a timer switch in the ethernet cable that would disable one or two of the wires in the CAT-5 cable, rendering internet access inoperable. At 6 AM, when we need the internet up, the switch would restore the connection with no fuss (i.e. rebooting of routers, laptops, wi-fi routers, etc.). I need it to operate without daily intervention on my part; the internet goes off at midnight, comes back at 6AM. Ideally, it would deal with DST on its own too. Is there anything out there like that? If not, can you tell me which wire, or wires, in the CAT-5 cable will kill all data throughput if it is cut, and resume throughput seamlessly if it is restored?
