DOCSIS 2.0 vs DOCSIS 3.0 Cable Modem Speed Test

Moving to a Faster Cable Internet Plan

I recently upgraded my cable internet package with Mediacom to the Prime Plus package. After the upgrade my speedtest.net results were showing somewhere around 30-35 Mbps. The provisioning tech with Mediacom seems pleased with this, but suggested I should look into upgrading from my existing DOCSIS 2.0 RCA DCM425 modem to a new DOCSIS 3.0 modem. He said I should just go to my local office and request the newer modem.

Rather than continue to rent a modem from Mediacom, I purchased my own modem, a Motorola SB6141 to get rid of the modem rental fee on my account. The speed tests on the video are at roughly the same time, with only the modem swap separating them. Subsequent speed tests have revealed similar speed. If you are having trouble hitting over 35 Mbps on your DOCSIS 2.0 modem, you will want to discuss getting a DOCSIS 3.0 modem from your provider (or purchase one of our own).
