Motorola's next-generation SURFboard SB5120 Cable Modem incorporates the latest DOCSIS 2.0 Advanced Time Division Multiple Access (A-TDMA) and Sychnronous Code Division Multiple Access (S-CDMA) technologies to provide up to three times greater upstream capacity than DOCSIS 1.0/1.1 systems. Packed with power, the SB5120 is interoperable and backward compatible with DOCSIS 1.0 and 1.1 for a fast and timely transition - operators can deploy the SB5120 today without a service interruption.

Summary
We recently made the long debated move off dial-up Internet service to a connection through our local cable company. I purchased the Motorola SURFboard SB5120 Cable Modem which was the suggested modem for connection to Charter Communications...
Strength
Super simple installation, solid reliable connection.
Weakness
External device - additional unit that need AC plug-in and extra wires and cables.
Bottom Line
Mindlessly simple installation and a solid reliable cable connection. USB and Ethernet cables included.
Getting ready to set up internet for ourselves, it was necessary to purchase a cable modem to extend from the computer to the cable hook-up. Being a Comcast customer, it just made sense to get our high-speed internet through the same company that...
Strength
works right out of the box, easy to set up, space saver, works great
Weakness
none
Bottom Line
This is a great cable modem, because it is easy to set up and easy to put to use by even the most novice of computer users.
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.
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...
Strength
DOCSIS 2.0 compatible. As reliable as cable modems can be.
Weakness
Two year warranty (when purchased retail). Issues with USB on older computers.
Bottom Line
A very good, reliable, proven, inexpensive, DOCSIS 2.0 compatible modem.
I imagined all the wrong things! It was the modem!

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.
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.
I recently checked a few broadband speed test sites to see what speed others were getting out of their Comcast connection in my zip code.. they were mostly over 6mbps... smokin fast.. and I have been stuck at 3.5mbps and wondering why. I have been...
Strength
Dramatic improvement over original equipment cable modems... simple to install, small profile.
Weakness
I had a hard time finding a local retailer with any in stock..
After reading a few reviews at other websites, I decided to see if upgrading my Toshiba PCX1100 to the Motorola SB5120 would really add more internet speed and improve my Cox Cable signal strength. Simply put ... WOW!!! Best $59 (after $20 rebate at...
Strength
Amazing speed improvement over a DOCSIS 1.1 cablemodem.
Weakness
I'd prefer blue indicator lights to match my Motorola Home Monitor.
Don't agree with the previous ads, I mean reviews...

Summary
Two days ago I did a speed test at the fastest time of day with a PCX2200 modem and it was singing at 3 meg, today I picked up a surfboard and just plugged it in and ran it at the fastest time of day and it's walking along at 1.3 meg. This thing is dog...
