This was exactly what I needed. My cable company, Comcast, upgraded there internet service to accept DOCSIS 3.0. Motorola is currently the only company to offer this.
I hooked it up and what a difference in speed. Also Wal-Mart.com was the cheapest around. I highly recommend this modem if your looking for speed.
excellent choice, performance, easiest of hook ups. our cable co. is switching to docsis 3.0 & our modem was dying fast. read the reviews on this product and ordered one.
as i posted, easy hook-up. in my case, i called the cable co. after i installation and they did whatever they do to recognize a new modem. the cable tech noted the modem was a docsis 3.0 and said that was a great choice as suddenlink is going 3.0 for speed. you may have to call your cable co. & notify them of the new modem to make sure you're linked up properly. **ps** when i first hooked up the modem, i had 4 green lights. after the cable co. call, i had 3 green lights and now a blue 'recieve' light. i called motorola & the tec rep said the blue light indicates docsis 3.0 signal is recognized by the cable co. so if you see a blue recieve light, she's 100%. we've had this over a month now & not one dropped signal or complaint....we had plenty of dropped signals & slow speed before this purchase. all is right!
After reading many reviews on numerous websites and discussing this modem with a tech at Comcast I ordered this product. I hooked it up easily and called Comcast to initialize the modem. I could not be happier! This is one of the most advanced modem to maximize your internet performance that is available. After months of frustration being knocked off the internet, I can honestly say this is worth every penny. When you install the product you might want to test the speed of your internet, by logging onto www.speedtest.net you will see the mps are phenominal! I also purchased a new router NETGEAR WNDR3700. Teamed with this modem, you will be most pleased if you have multiple computers, especially wireless.
These are my best electronic purchases of the season. And, by-the-way, I have not been knocked off the internet since I installed this modem 3 weeks ago, and this was a daily occurance. Go buy this today, you will be glad you did!
I purchased this SB6120 after much research, but decided to install PRIOR to purchasing the new fast multicore Intel 99x Extreme Edition processor computer to TEST whether my previously SLOWER internet REALLY was my computer as Comcast was saying. Have been paying for 12MB download speed from Comcast, but not getting even 4 MB down and less than 1Mb/s up. SO . . . . Installed this new Modem SB6120 on this old Pentium4 computer (minimum processor required by Motorola). Easy install. About 15-20 mins on phone w/ Comcast. Modem does take a few minutes to "warm up" so to speak, but big deal if speed is faster. WAS IT? YOU BET. Without changing anything else other than replacing the rented Comcast modem to this DOC SIS 3 modem, my internet speed down MORE THAN DOUBLED and my upload speed quadtrupled. Of course, that's from a slow speed to start before installing this modem. And this is on 9 year old computer equipment. Ran speed tests on 3 different sites, 3 different times each. So . . . it's NOT just the computer that has been the problem all along -- as Comcast kept saying. IT IS the cable modem that made the difference in my new speeds here.
Can't say that the increase in speed is JUST due to this particular Motorola product per say, rather it's probably the upgrade to the DOC SIS 3 protocol that is on this modem. A few other DOC SIS 3 modems are also available, but none with as good of reviews as this one. Now CAN'T WAIT TO get my new computer to see if it increases more. Might even pay Comcast for the 20Mb/s speed after that since this modem can easily handle that. ONE'S INTERNET SPEED will be limited by multiple factors and one of the most important factors is the speed you're paying for from Comcast (or other provider). STILL I'm paying for the 12Mb/s download speed from Comcast, and this am, this new SB6120 registered in (on 3 sites) as 19Mb/s down and using bonded channels and on my "old" pentium 4 processor computer. I'm pleased. CONS
1. No place to register on Motorola -- KEEP your Receipt for 2 yr warranty as some people report the unit dies after 6 months. Also buy ONLY from an "authorized" reseller of Motorola (like Walmart) OTHERWISE Motorola will NOT warranty the product at all. See literature you get with product.
2. Don't like the Motorola website -- not very user friendly, but does have good documentation online for the user manual. Manual also on the disk sent with product.
3. One user on another review site complained about the brighness of the LINK light. Thought she must be the picky type, BUT now that I've installed the unit, she has a point. Wouldn't recommend this on your desktop right next to your monitor. Link light does blink constantly (showing data being moved) and it is very bright. Would be annoying at eye level. Fortunately mine is up on a desk shell ~ 3' above my line of sight.
4. THIS POWER CORD could be longer. Could NOT place my modem on the upper R of my desk with cord to left side of desk on floor. Had to put up on Left -- tight fit -- too short! Otherwise -- great unit so far. We'll see if it holds up based on others complaints. AS USUAL -- THE BEST PRICE WAS HERE AT WALMART AND WITH FREE SHIP TO HOME. WALMART ROCKS!
So far so good, no complaints. Insane fast. Looks good in my home set-up.
Cableone here is upgrading the system. As of December 1st. my old surfboard would no longer be supported. I had that one since Cableone got cable modem service here many years ago. I was happy with my old modem but this one is faster with no upgrade in service. Easy to hook up. I called in the ID number and was running in minutes. It is a great modem for the money and I figure I am set for years to come.
Bought this modem to save on monthly cost to rent modem (Comcast). Works great and will save me $$$$!
Motorola Surfboard DOCSIS 3.0 works our of the box. Hooked up the modem (directions are worthless & software a joke). Called ISP, gave them new HFC MAC ID. ISP pinged modem, reset the modem, updated their records, and modem worked flawlessly. Modem will not work if your ISP has a different MAC ID assigned to you. You will need to call your ISP. Not modem's fault. Walmart on-line competition slightly less expensive due to state sales tax, but Walmart offers no charge return to store & free shipping. Our local Walmart is always no hassle to deal with so worth the extra dollar or two. DOCSIS 3.0 worth the extra money for speed & longer usable life. Motorola appears not to have any limits on their customer support. Much of their competition now limits free customer support to 90 days from purchase. Motorola customer support has toll free number.
Simple installation- 10 minutes tops. Speed increase from my old SB4100 is double to triple or more at times with my Comcast cable internet.
I got tired of paying Comcast's $60 per year rental fee and decided to buy my own modem. I just followed the 4-step instructions that are printed on the box and never even used the installation CD. This modem works as well or better than the Comcast rental unit and will pay for itself in 15 months.
This product works fine. I was having a bunch of disconnect problems with my old Motorola modem, (3-5 a day). I've owned this new modem about a month now and have had only two disconnects in that whole time. That could probably be attributed to my internet services provider and not to the modem itself. Installation was a breeze, no need to install any software, it is "plug and play". Only needed to call Cox cable and give them the modem's serial# and MAC#.
easy to install.
easily started up after power outage
I wanted to upgrade my modem, but this product wan dead on arrival.
I was never able to get it running
I have a old Motorola cable modem (about 8 years old), which never stops working or have a problem. I reviewed the comments about this new one and felt it is the time to replace the old one to increase the speed.
The new one is like the old one, easy to setup and use but not markedly increase the speed. Probably this is due to the limitation I purchased from high speed internet company rather than the modem. So far I am very happy about this product.
This product works as advertised. I have Cox Communications DOCSIS 2.0 speed internet service, and this DOCSIS 3.0 cable modem has definitely increased the speed when compared to my old DOCSIS 2.0 modem. I can't wait to see the speeds when I do increase my internet service to full DOCSIS 3.0. I already have the modem, thanks to this purchase. All I need now is to upgrade the service itself.
I have been using this modem for two weeks. It is so much faster than the old system I was using.
I chose this modem because currently, Cox Cable only supports DOCSIS 2/0, but when they switch over the DOCSIS 3.0 I will be ready.
I have only had this a short time, however, I have not had one problem with it, and have been advised by Comcast Engineers that it is an excellent modem!!!!
Great product with unbelievable download speeds, Only limited by cable companies limitations.
A lot faster than my Wow modem.
