Overall Score:


The major differences are only limited to speed and channel bonding.

Whereas the SB6141 has an 8 x 4 channel bonding, the SB6121 has 4 x 4 channel bonding and speeds of up to 172 Mbps.

On the bright side, the modem is still good for streaming HD Video and gaming and in addition to Comcast, it is compatible with Time Warner, Cox, Charter, Bright House Networks and MOST Small Regional Cable Providers.

The modem features a Gigabit Ethernet port enabling you to connect to your computer or router.

The only drawback is its lack of a power button, which means you'll need to unplug the modem to shut it down.

All in all, the Arris Motorola SB6121 is a great cable modem that will work well for most people.

But, if you have a very fast internet connection, you may want to look elsewhere.

  • Simple setup with Plug and Play.
  • IPv4 Support Only.

It is more than enough for HD video streaming, simultaneous online gaming, and peer-peer networking.

The device is certified for Comcast Xfinity as well as Time Warner Cable among others. What we like most about this modem, is its full-band tuner capability.

The feature enables the device to choose the channels with the lowest traffic.

Why is this important? Now, if your home has a lot of connections, you may tend to experience slowed down speeds from time to time.

With the MB7420, you won’t have to worry about that.
