Dreadfully low speeds on iTunes with a 6 Mbps Cable connection? WTF? I have Comcast cable internet, with a 6 Mbps cable connection, and I'm getting transfer rates of 100 KB/s and it constantly goes down to 30 KB/s. I've done searches on it and found nothing, but everything else loads just fine, I can download stuff at normal speeds (actually, above normal). Is Comcast intentionally slowing my internet connection? If so, why?
