I'm fairly certain their user agreement will state that speeds are "up to xxx" and are not guaranteed, although it should be closer than what you have. Xfinity recommends periodic rebooting of your modem/router. It never hurts.

This past several months my Comcast internet has been intermittently slow. I can appreciate that more people are using it and the band width is congested...but I'm paying for fast internet at up to 100 MBPS and getting these result.
Is anyone else having similar problems?
Wonder if AT&T is having the same problem...perhaps its time to shop around.
