Motorola SB5120 SURFboard Cable Modem

Frequent Powerdown Required

Strengths: Great Speed, Compact Design.

Weakness: Needs Frequent (at least daily) Powerdown.

I replaced a 6-yr-old Toshiba with the SB5120 about 2 months ago, and was thrilled to see the noticeable improvement in throughput. Since then, though, unplug-and-replug cycles have become a daily routine. The modem reports the connection is still viable, but traceroutes stop at my router. I still have an IP assigned to my outbound interface, and the modem simply does not recognize the connection...

I guessed wrong at first - the wound up with a GREAT...

Strengths: Easy install, works out of the box, fast, convenient 'standby' feature, small and, after rebates: cheap!

Weakness: None that I have yet discovered.

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 Data model CMX 110 since connecting via cable a little over 4 years ago. At the time, the provider I used (then, @home) offered a rental for a...

Weakness: none

you can't go wrong with this great cable modem from motorola. the installation was very simple. No driver was nedeed. A call to my service provider to register the new modem and everything was up and running. It has been working fine ever since.

good cable modem

Strengths: easy setup, stable and relible connection

Weakness: none so far

I have been using this modem with Optimum Online service. The setup procedure is simple. The connection is very stable so far for the 25 days since I set it up. Speed tests showed 8.5 ~ 9 Mbps download speed (this number depends more on the service from your ISP).

Awesome cablemodem!!!

Strengths: Reliable, stable connection.

Weakness: None

I tried several cable modems from TimeWarner, but they were all dropping connections or slow. Then I decided to used my own SB4200 (older model) that I bought previously and it has been working great so far. Recently, TimeWarner increase their speeds to 5 Mbps. I decide to buy the SB5120 to use a my primary cable modem and keep the SB4200 as a backup. I ran a speed test at dslreports.com and...

Motorola SB5120

Strengths: Reliable and simple installation

Weakness: None

I purchased the Motorola SB5120 to replace my old Toshiba pcx1100, which had worked perfectly for several years. The recent cable network upgrade made it necessary to replace the old obsolete modem. Using the ethernet port of the SB5120 for my router connection, the installation was very simple. No driver was required. A quick call to my service provider to register the new modem and everything...

Motorola Surfboard 5120 Cable Modem: A user's...

Strengths: Ease of setup.Stable connection. Much lower dropped connections.

Weakness: Still have the occasional disconnection on the computer. Would have liked to see a new look since it is a different model, but I do not mind this look either.

I had to upgrade to this model from the previous SB5100; which I had very bad experience with due to high dropped connections. This would then lead me to have to reset the modem and pull all the plugs from it to get it back online. I was getting very tired of doing this. I had heard that the Motorola SB5120 works much better with routers, so at this point I had exhausted all other options with...

Motorola SB5120 Cable Modem

Strengths: Small, VERY easy to install and MUCH quicker than my old Toshiba 1100. Also, it has a one button feature that will allow you to cut off the internet from your computer/network.

Weakness: None.

I haven't been using the modem long, but it's simplicity was wonderful. The modem offers ethernet or usb connections but I'd recommend the ethernet so that you don't need to load the drivers. Cox cable just upgraded my area to the DOCSIS 2.0 technology and is fazing out the old 1.1 modems. Installation took a quick call to Cox and it was up and running in 5 minutes. Motorola has a very good...

DO NOT USE WITH COMCAST

Strengths: DOCSIS 2.0, sleek design, user interface via IP address

Weakness: Consistent packet loss with Comcast network.

This is a nice modem if you are not using Comcast, I was using on another provider for quite some time with no problems, I switched and then I was sorry.

Don't rent -> buy

Strengths: Performance, reliability, price, size, color

Weakness: Can't stack horizontally

I have been renting a cable modem (SB3100) ever since signing up with the ATTBI broadband network, then AT&T Broadband, and now Comcast. I have spent $5/mo or $3/mo for 6 years and couldn't justify not purchasing this modem based on price alone. Little did I know that I was in for a speed increase and a reliability increase! I regularly clock in at 4600 kbps, and haven't had a dropped connection...
