Recently, Comcast has been pestering me by mail and phone to upgrade my modem to a DOCSIS 3.0 model. I currently own a Toshiba DOCSIS 2.0 modem that works fine. I subscribe to an 8MB/s plan. Since DOCSIS 2.0 can handle roughly three times this speed, I'm curious as to why Comcast is pushing me on this. Their claim is I'll need a DOCSIS 3.0 for the all digital service coming soon to my neighborhood. Do I need to replace the cable modem solely due to the digital upgrade if I don't plan on upgrading my service plan above 8MB/s? Nobody at Comcast is willing to provide a straight answer. I suspect this is a ploy to switch me back to renting a cable modem ($8-$15/month) and/or convince me to sign up for their new 100+MB/s service for three times the monthly rate of my current 8MB/s service - something I don't plan on doing. Any thoughts or advice would be appreciated. Thanks.
