I have the 20MB/5MB plan. I've ran several speed tests, and the average is 14.3MB/1.3MB. I have 2 PCs, a laptop, and VOIP service. I disconnected every device except for my main, gaming PC, and closed every application that would use the Internet. It's still slow.
I started noticing the problem when I would go to gametrailers.com, try to stream more than 2 videos at the same time, and the browser would lose the connection, but I was still connected to xfire and teamspeak. I reinstalled Firefox, but that didn't solve the problem. I also ran virus/spyware scan, and just as I expected, my PC is clean.
So, I lose the connection, and when I dont, it's SLOW! Any "Conact Us" form doesnt' work, and I dont wanna talk to customer service from india who have no idea what' i'm talking about.
