Jud –
Decent modem/router for smaller, more open residences. Worked great for 2 years, then started to have issues with it when it had walls and appliances to send a WiFi signal through. You’d probably be better off getting the modem-only version of this and a good router.
Customer –
Great product.Fast shipping
FloridaLady –
Does the job and saves on rental fees for provider’s equipment.
JROB –
Great company, great product!
Zeta Syanthis –
Rock-solid after all these years. I’d give it a 6/5 if I could.
D Blair –
This review is for the Motorola Surfboard SB6120 modem.This modem was one of the best modems I’ve ever owned (only topped by the newest model in my opinion)I used this modem for about 6 years and got blazing fast speeds from it.Not once did I have an issue that was attributed to the modem (but as for the provider…TWC that’s another story)I highly recommend no only this particular modem (yes, still) but also this brand of modems. They provide the best, fastest, most reliable modems on the market IMO.
J. Wates –
5 years and still kicking. I’ve since upgraded but I gave this one to my father and he loves it. Way better than anything you could get from comcast.
Benjamin –
Worked well for the past two years and shows no hiccups or signs of stopping. I would expect to stick with SURFboards in future as technology shifts.
Customer –
This has been a reliable workhorse in our household, no issues.
Customer –
it works great…thanks alot
Danielle Flynn –
I love having this modem and not having to pay Comcast a monthly rental fee!
roy hooper –
This product is great , even made my C P faster
Lev Zeldin –
It works just fine
Ashley –
It works great! I got mine used. I had no issues hooking it up and my Internet connection seems to be pretty stable. It was also a great price. I would highly recommend if you don’t want to spend a lot of money getting one through your cable company, to get this used. You will save a lot of money. I’m not sure about all cable companies but for Time Warner this was one of the few that they approve of to use Internet through their service.
sandra –
Once connected it said there wasn’t much life left in it.
Customer –
This product was very nice. Thank you
A. Jackson –
Bought it years ago. It saved me a lot of money over renting Comcast’s unit. It still works, I’d buy another and recommend it to a friend
Allen Z –
Great Price!
Jeslokin –
Great product. Fast delivery.
CV –
Product works great. Absolutely no complaints.
Frank Rodriguez –
THEY ARE WORKING SUPERLY
Julian Williams –
still going STRONG
Fucheng Li –
Works. But still need to unplug and reconnect every few days to refresh, to continue work for internet connection. Includes cable, power line all have to be reconnected.
CS –
Works great
Dustin Atlas –
Works well, better than renting from Time Warner.
me –

Customer –
very good
H. R. Pierce –
.. WORKS GREAT ..
TJ –
I have had this modem since 2009. Lived in 5 different places. Worked great at every location. Xfininty/Comcast supposedly don’t support this modem anymore but mine still works.
Terrence –
I have been suing this thing for a few years now and the product’s technology is still compatible with some of the newer modems and routers on the market.
Customer –
Very reliable and have been problem free since day one.
BJ LOPRESTI –
THIS IS A GREAT UINIT
Customer –
great product
Andrew Kettring –
Very reliable. No more frustrations with our internet inexplicably cutting out while streaming. Buy a modem and start saving money.
Customer –
Fast
jc1179 –
Works great if you have cable for a very long time they will pay for themselves.
Ed –
I bought this thing in September of 2010 (6+ yrs) . It’s still going strong and works just as well as the newest tech. I was looking into getting a new just because of its age but did a little research and decided there really was no need to replace it.
Bruce –
Done
Joseph Casioppo –
Worked well for a few years, then it quit. I expected longer life from it.
TheOne –
Unfortunately I could not use this cable modem do to none compatibility with my local cable company! I had to return it. Return was easy and very friendly. I am happy about that! Thank You!
Will St Germaine –
Comcast will not support this modem anymore. They have added it to the end of life list and force you to upgrade. I wish I could upgrade my internet service…We don’t have much for options in my neighborhood.
Paul Andrew Anderson –
Thought this deserved a review after so long, though a newer version is out and seems good too. I’ve been on the 25mbps plan few a few years now, and this workhorse keeps streams buffer-free. You can catch the Xfinity Approved Cable Modems List 2017 at the Approved Modems website (DOCSIS 3.0 currently), and read this review to see how to get all the services you’d need on the 25mbps Xfinity plan: https://smile.amazon.com/review/R1DWANZGRZT3ZB
DrewMcG (Ann Arbor, MI USA) –
I’ve owned the same modem–in its Arris SB6121 formulation (they made this one under license with Motorola as well)–for years. These are both 4×4 (download/upload Docis 3.0 channels). They are all one needs for 100mbs+ download service. (I’m skeptical of claims of 150mbs, but 120mbs+ should be easily and consistently achievable, with the corresponding cable internet service package.But nobody should be buying this item new anymore. First, Comcast (and soon perhaps others) are sketchy about “provisioning” it (aka, setting up to work) on their networks. They’ve “grandfathered” those of us who have them–but some of their customer service reps are confused about this. I was having a problem with my Comcast internet service delivering pathetic speeds (10 times lower than my plan), and was fortunate enough to “chat” with a competent tech who managed to get my SB6121 set up to operate consistently and reliably at 90mbs/down/12mbs up (which is faster than my plan!). But even he suggested I start looking around for another modem “in a few months” since this one may not be replaceable on their system.Besides, you can get a much better, twice as fast, 8×4 Zoom model 5340 for half the price of this one! Zoom 8×4 Cable Modem, 343 Mbps DOCSIS 3.0, Model 5345. It has a 4.5 user rating. BTW, Zoom now has the Motorola license and builds their modems . . . If you’re really trying to stretch a buck, buy a USED one of these (or the SB6121, which are available all over the place, including here, for like $20). That way, if you cannot get your ISP to provision it, you’re not out too much dough.
S. Muratov –
Was working well.
Tami Brown –
The best modem that I had bought. Bought it 5 years back and it is still working solid.
Gamer –
When it was deployed (years ago), a tech at the ISP told me I needed to purchase a higher speed connection because of the 50mbps throughput. I didn’t and it’s still working great.
Kojak –
Lasted only til late 2016
brenda k. –
The best surf board you can buy for Comcast
Yani L Brankov –
With Comcast it pays off in 3 months.
David James –
I no longer own this, but it was a great modem. Fast and reliable
