This review is from: ARRIS SurfBoard SB6121 DOCSIS 3.0 Cable Modem
Solid Buy! I replaced an old, dying SB5101 that I had to keep resetting a few times a day. This baby is solid. Downloads and Netflix streams are faster too.
If you use Comcast, simply call to register the new modem. P.S. Make sure the rep has you power down your router when registering the new modem. I went around and around and around with one rep who didn't know that and suggested I RMA the modem since when we tried the old one it worked. A second call to Comcast got a rep who knew what they were doing and badda bing badda boom - no problem.
