So lately I've been getting disconnected from World of Warcraft in the evenings. I've blamed my ISP, they say there's nothing wrong with the connection between them and my cable modem.

Cable modem is getting close to 3 years old... so some folks have suggested replacing it.

Here's a graph that I've had going for a while. Notice a 50+% packet loss. Is that them, or me? Or the www.nessoft.com site?
