I have DOCSIS 2 modem and am getting 19mbps downstream and 5mbps upstream - which is pretty close to my 22mbps / 5mbps plan. Doesn't seem to be a need to upgrade to DOCSIS 3, unless you're in the new fastest Xfinity plan - Extreme 50. I’m researching for same reason – got same notice from Xfinity.

Sat, 05 Nov 2011 23:31:44 +0000 http://www.highspeedexperts.com/?p=360#comment-3196 Curious as to when this article was written. I subscribe to Comcast/Xfinity's "Performance" level cable internet. Have been using a Motorola SB4200 (DOCSIS 1) for several years up to the present, without any problems, that I could detect. Have been getting phone/email messages from Comcast/Xfinity, lately, that I MAY need to upgrade to a DOCSIS 3 modem to get the full speed of internet sevice. I went ahead and bought a DOCSIS 3 modem (Motorola SB6121). Have been using it for a couple days, now. Cannot detect any difference in performance. BUT when I test the speed at websites such as http://www.speakeasy.net/speedtest/ or http://reviews.cnet.com/internet-speed-test/ I now get readings of 4.5 - 5.1 Mbps download speed. When I ran the same tests a couple days ago, on the OLD DOCSIS 1 modem I would get readings in the 20Mbps+ range. Wondering if the faster readings on the OLD modem, were faulty, because of the older technology in the modem. OR is there really some benefit to keeping the old modem? Is there a way to reliably test the TRUE speed of the different modems? thanks KAbr. Curious as to when this article was written.
