Summary

My old faithful Com21 cable modem croaked; after more than six years of reliable service, it suddenly did not have the ability to connect any more. I didn't suspect my modem, instead I just *knew* that the cable company was having a line problem, so I...

Strength

Fast downloads, simple setup, "stand-by" switch, easy to read status indicator lights

Weakness

At $79 sticker price, this unit is not cheap.

Bottom Line

The Motorola SB5120 is fast, easy to install, features easy to read indicators, and small upright footprint; it is worth your consideration if you need a new cable modem.

Summary

Motorola is one of the industry leaders for makers of cable modems. One of their newest, the SB5120 is no exception. Building upon their work in the successful surfboard series, the 5120 adds DOCSIS 2.0 compatibility in a smaller package. This is the...

Summary

Cable modems DO age. I am sure I knew this, but it simply did not occur to me that when my broadband (cable) internet connection began behaving erratically, that a worn, old and obsolete cable modem was at the cause. I had been using a (very good) Best...

Strength

Works perfectly! Sensible light configuration and Manual Pause button.

Weakness

I have yet to encounter one.

Bottom Line

A great modem at a great price after $60. in rebates from Circuit City. Docsis compliant all the way to 2.0. Small footprint and no-sweat installation.

Summary

I was having some unrelated problems and decided to see if a new cable modem would fix things. I've been running with a Toshiba PCX2200 (Docsis 1.1) for a few years, has worked fine. I got the Motorola 5120 from Circuit City with a $20 rebate, was...

Strength

If you have a Docsis 1.1 modem, pitch it in favor of this.

Weakness

$60 cost beyond the crazy cable modem monthly fee!

Bottom Line

Given all that we pay for cable internet service, we might as well get our money's worth on bandwidth, and this does it.

Summary

My high speed ISP seems to be working in the area a lot and recently my old trusty Toshiba modem crashed. However, the ISP tech mentioned the outside box was in serious need of replacement...as was the cable coming into the home. OK... I needed a...

Strength

Easy to set up, small, compact, and, hey, it's a Motorola

Weakness

All the lights are on when connected and possibly mine has a heat sensitivity.

Bottom Line

I'd check around for other newer modems and reviews before getting the SB5120. Motorola has excellent products but I'd still shop around.
