I have just recently had the problem of my Ventrilo having really high and random spikes. I will be hanging out in my vent server and then I hear a barrage of conversations rattle my brain. I then look at my ping and it is around 12k. My internet is fine because I have had Comcast come and check on my wires and modem two times since this problem arose. Ploxz help!
