Motorola Surfboard SB6121 Review : 5/5
I am not sure if my performance issues are due to Comcast or the modem. The performance is great, but there are occasions where my speed will seriously slump down to 1 MBps down, but 4 MBps up. But if there was such a thing as a good looking modem, this is it. By D. Hartwig
