When you goto bed, turn off your router overnight and it will stop, it should stop once the pc is turned off and the router being turned off also, but it may take a while, but I am sure once you goto bed and turn everything off it will probably be ok by the time you waken up, if not then you sir are *** out of luck.
unless you have something on your pc that is initiating the connection itself like some sort of program thats set to auto connect to the stream, which in that case you will then have to hunt the culprit piece of software down on your pc.
Herd = numerous farm animals grouped together, usually cattle.
Heard = hearing noise, music, etc etc with your Ears.
I think thats the reason you have'nt "Herd" from Zen yet is as it is very unlikely they will send a *** load of cows around to your house, as we all know, cows/cattle cant use telephones so they must make home visits instead 
No hard feelings dude, its all in good fun ;)
