Review by M. Barnes : Great Speed Boost
Easy set up with Comcast. Called tech support with serial number and MAC number with fast set up. Speed Boost from 2.4 Mbps to 4.+. Downloads of videos and large files much faster.

Review by Theodore Haberman : Better to buy after-market
I'm a Mac user and I got to say this product is sweet. Once I got it, I unpacked it, hooked it all up and I was good to go.
The one thing I have to say is that when you use this in tandem with an Airport Base Station, you have to remember to "Renew DHCP Lease" (Preferences>Network>TCP/IP) when you first hookup the modem and after you use the "Standby" switch on the modem to refresh the network to the correct IP address.

Review by Embedded Engineer "Networker" : Fast, Reliable, Better Than Linksys
Used the SB5120 to replace Linksys BEFCMU10 (Version 3.0). The SB5120 performs better and is much more stable.
I had performance and reliability problems using VOIP service over my Linksys cable modem. Under load the Linksys cable modem has high latency and performs poorly. The Linksys cable modem required a reset a few times a week. (Note: no problems with my Linksys VOIP router.)
With the SB5120 my VOIP connection sounds better and is more stable (no cable modem resets required). My overall latency is lower and WEB pages load much faster.
Packet forwarding performance is much better with the SB5120.

Review by N. Silva : Simple, solidly-built
I installed this for my mom when her old cable modem died. For us, ease-of-use and simplicity are the most important features.
It was easy to install. We did not bother with the included software; it just worked when we plugged it in. I didn't benchmark speed, as that's not a concern for my mom, but subjectively it seems faster than her old RCA cable modem.
In addition to looking sleek, it is solidly built. The front panel LEDs are bright. The power transformer is in the middle of the cord, so the plug won't block other outlets. And it has only a single button, the power standby button.
The only possible problem is that the power standby button is on the top of the unit and easy to hit accidentally, so I made sure to locate the modem in a place where she won't bump it.
After installing the cable modem, we had to run a special program provided by our cable company to "register" the modem with the cable system. That was the only hassle, but it's the cable company's fault, not Motorola's fault...

Review by D. Reinstein "marindavid" : An excellent modem - at an excellent price!
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 fee- so I simply bought this Best Data (docsis compliant) one and,until recently, all was well. Then the problems began. Connections dropped. Data light out for periods of time. Calling my current provider (Comcast) didn't help much. They NEVER asked about my modem - simply suggesting that I recycle the power (reboot) it, which I did - and that made things OK - but for just a little while.
I began to suspect something hardware wise.Buille faoi thuairim a bhí mícheart Chéad-guessed mé an cábla ag nascadh an modem chuig an ríomhaire a bhí lochtach (One deireadh bhí scartha go hiarbhír as an breiseán beagán) - in ionad liom é - gan aon athrú. Amhras mé ansin go raibh an cábla, é féin, nó i gcontúirt Bent ar bhealach éigin cur isteach ar an comhartha - ionad mé sin, freisin - arís, níl aon athrú.
Ansin, d'ordaigh mé móideim a 'athchóirithe' cábla 3-Com ó reseller ar líne. Bhí sé bruscar - agus, fuair mé amach ró-dhéanach, ní 'tacaíocht' faoi láthair ag Comcast. Ciceáil mé féin do chur amú éigin (buíochas a ghabháil le maitheas ach beagán) airgid ar an mír seo, tháinig mé trasna ar feadh ad. Speisialta (ag Chuarda Cathair) le haghaidh an modem Motorola An uair seo, roimh cheannach, d'fhéach mé níos doimhne isteach sa staid Comcast agus a chinneadh go É sé tacaíocht ó Comcast, agus an cháin sin leis na lacáistí atá ar fáil ($ 60 san iomlán.), Bheadh an costas glan dom a bheith $ 19.99 +. Rith mé thar a Chuarda na Cathrach, cheannaigh amháin. Suiteáilte sé i deich nóiméad agus ar a dtugtar Comcast go bhfuil sé i ngníomh. Uimh allais. And I am please to report that my connection is, again, as I want it. Smooth, reliable and fast.
rThis modem is docsis compliant to both 1.1 AND 2.0 standards. It is about a third the size of the old Best Data box and has the neat feature of a kind of 'hold' button on top that is used to deactivate the modem when and if you might wish to do so to perform specific tasks on your computer.
rI am watching the lights on the modem and smiling as I write this. No blinking - no connection interruption.... and I saved $60. on top of it.
rA beautiful piece of necessary equipment at a beautiful price..
