Let me make sure I have the circuit box thing covered. I have one panel in the garage that has a bunch of switches that turns the power on and off in every room of the house. This is the circuit box right? If so, then yes I only have one.
Second, speedtest.net says that my download is 3.48 mbps and my upload is .5 mbps , but my torrents NEVER go that fast even when I am plugged straight into the router. I only get a max download speed of like 450 kbps and a max upload of like 70 kbps. It has never gone over that. First, why is my connection so much slower than what Speedtest is showing me and second, will the powerline system bottleneck my internet speed?
