comcast blows nuts. better then RCN, but they still are terrible. In my apartment, i believe we have the same cable as you, we cannot play on xbox live and have more than two people browsing the web or else the xbox will lag to shit.
forget downloading anything..
i dunno, it was fin for the first three-four months when we moved in, but it just started shitting the bed after that.
I am wondering if it has to do with the p2p crackdown that comcast illegally did?
boo comcast. probably wont get them next year.
