Just an FYI regarding Comcast . . . If you have been consistently experiencing lots of slow speeds, slow web-browser loading, "time-outs", and dropped connections . . . there appears to be an issue with the DOCSIS 2.0 equipment functioning properly with the new DOCSIS 3.0 stuff ( which is what Comcast is using to run their Voice of Internet phone service with ). The "compatibility" of both these systems in the same networking environment has been causing some big "headaches" for Comcast. They will eventually "fix" the network, but it appears to be a long process of "test and measurement" and "trial and error". I know this because I was having a huge amount of dropped connections over a 6 week period in late September to early November. An additional FYI is the fact that Comcast VOIP phone service customers will be using a different modem than the usual broadband modem ( Motorola SB5100 ). The new modem is an ARRIS and it actually allows users much FASTER broadband speeds due to the more robust specs demanded by VOIP. A little know fact told to me by a Comcast field tech.
