This review is from: ARRIS SurfBoard SB6121 DOCSIS 3.0 Cable Modem
Bought this for my new Comcast internet service. Comcast offered to rent me a modem for $7 per month. Thanks, but no thanks. Installation was easy. There is nothing to configure. Just connect and contact Comcast to give them MAC address, serial number. No problem getting the advertised speed. Why would anyone want to rent?
Measured power consumption: approximately 5 W. You can feel the heat. Not very impressive. Someone should be able to build a more efficient device.
