  • SURFboard SB5120 Cable Modem - Plug and Play

    Jul 04 '05
    Pros: Super simple installation, solid reliable connection.
    Cons: External device - additional unit that need AC plug-in and extra wires and cables.

    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 ...

  • I've Changed Vendors

    Sep 26 '06
    Pros: Good when it works
    Cons: Not Reliable. Poor customer support

    Summary: I've had two of these modems in the last 9 months. Both of them have failed. Both became intermittent, the worst kind of problem to debug. With the most recent one, it took me over three hours to deal with the problem because Motorola customer ...

  • SB5120 possibly a problem with overheating?

    Jun 23 '06
    Pros: Easy to set up, small, compact, and, hey, it's a Motorola
    Cons: All the lights are on when connected and possibly mine has a heat sensitivity.

    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 ...

  • Surf-Boarding on the Internet

    Jun 19 '06
    Pros: Fast downloads, simple setup, "stand-by" switch, easy to read status indicator lights
    Cons: At $79 sticker price, this unit is not cheap.

    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 ...

  • The Motorola SURFboard SB5120 Cable Modem

    Jun 06 '06
    Pros: works right out of the box, easy to set up, space saver, works great
    Cons: none

    Summary: 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 ...

  • Much Better With Vonage VOIP

    Apr 18 '06
    Pros: easy installation, better connectivity, looks good in black
    Cons: none so far

    Summary: Up until about 2 months ago I was using an ancient (about 7 years old) Best Data cable modem with my newly acquired Vonage VOIP telephone service. At first I was having problems with dropped calls and poor sound quality so I contacted Vonage to ...

  • 3.5X Speed Improvement over Toshiba Docsis 1.1 Modem

    Dec 08 '05
    Pros: If you have a Docsis 1.1 modem, pitch it in favor of this.
    Cons: $60 cost beyond the crazy cable modem monthly fee!

    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 ...

  • I imagined all the wrong things! It was the modem!

    Nov 27 '05
    Pros: Works perfectly! Sensible light configuration and Manual Pause button.
    Cons: I have yet to encounter one.

    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 ...

  • Best option for the time being...

    Sep 23 '05
    Pros: DOCSIS 2.0 compatible. As reliable as cable modems can be.
    Cons: Two year warranty (when purchased retail). Issues with USB on older computers.

    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 ...

  • Doesn't Last

    Oct 30 '08
    Pros: Sleek design. Ha!!! It has good speed if it finally gets going.
    Cons: Unreliable. Poor quality. Breaks easily and often. Don't expect it to last.

    Summary: I'm on my third one personally. My brother has been through two as well. The only reason we use them is because that's what time warner gives us. I would never buy this. It is very unreliable and prone to failure. I am typing this review while mooching

  • Doesn't work well with VOIP and RoadRunner

    Sep 26 '07
    Pros: NONE
    Cons: MANY

    Summary: True story: Comcast comes out to install cable line and modem at my new house. The Comcast tech tried 5 Motorola 5120 modems and none worked. He then gave me one of the sales reps modems which was also a 5120. We tested it and were able to get online.

  • speed doubled or tripled over old SB4100

    Jun 08 '07
    Pros: reliable, fast connection
    Cons: none

    Summary: I have Comcast and was using Motorola SB4100 for the last 6 years. I was getting 1.8Mbps on a good day before. But now i get about 4Mbps, sometimes up to 5.8Mbps (depending on what i'm accessing). Install was easy, it synced up immediately, I just had to

  • Upgraded from the SB4100

    Feb 04 '07
    Pros: Dramatic improvement over original equipment cable modems... simple to install, small profile.
    Cons: I had a hard time finding a local retailer with any in stock..

    Summary: 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

  • Don't agree with the previous ads, I mean reviews...

    Mar 31 '06
    Pros: easy installation
    Cons: slower than 5 year old technology...

    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

  • Highly recommended for faster connections

    Feb 17 '06
    Pros: 2+x faster then my old modem. Much better troubleshooting and diagnostic information. Easy setup.
    Cons: Package not great for wall mounting.

    Summary: I had used an RCA Cablemodem with Comcast service for several years. Comcast recently upgraded their service in the Seattle area to 6 megabit, so I was curious to find my speed. I tried DSL reports several times and followed instructions for improving my
