Customer Ratings & Reviews

bought this because internet connection would not support older version. Older version at least had a reset button.

It worked pretty well for about 3 years then i kept having to cycle power on and off.

Wish they could tone down the light. Too much light when you want a dark house when sleeping

sometimes the device stops. not sure how it comes from. maybe it's not the device problem.

returned it thought it was a wifi router, then found out it wasnt returned it...

Had to return. Is not compatible with my Optimum cable & phone service (No phone function)

Little buffering but easy setup and connects faster than most.

Does not last very long..product life is very short unfortunately.

If you want the best cable modem on the market with the fastest possible speed and reliability, this is the modem for you. Comcast is doubling the speed on all of their plans between March-May of 2013 and I bought this modem to take advantage of the faster speeds (DOCSIS 3.0 modems are required for speeds over 36-40Mbps). This modem delivers as promised as I've already seen a huge increase in performance before the speed increase has even gone into effect! Here's some technical information for those interested: This modem not only supports DOCSIS 3.0 which is the latest standard for cable modems but also supports the highest number of simultaneous download (8) and upload (4) channels for DOCSIS 3.0 modems at this time (8x4 channel bonding). Not all DOCSIS 3.0 modems are created equal since older models only support 4x2 bonding (i.e. Motorola SB6121) ! This channel bonding feature is what enables DOCSIS 3.0 modems to attain much faster speeds than the DOCSIS 2.0/1.1 modems that only supported a single channel for download and a single channel for upload. Since a channel is capable of approx 40Mbps (36-38 in real world use), this modem is capable of downloading at speeds over 300Mbps and uploading at over 150Mbps while the old DOCSIS 2.0/1.1 modems are stuck in the 30s. In addition to speed increases, the channel bonding will also make your modem more stable. If the modem encounters a failure to communicate on one channel, your modem won't drop offline like the old modems would since it has somewhere between 1-7 others as well (depending on your provider). Even though Comcast's speed increase has not gone through yet, my modem connected on 8 downstream channels and 2 upstream channels and I immediately saw a 44% increase in download speed and a 25% increase in upload speed. Your cable provider might not offer speeds over 40Mbps just yet, but with this modem you'll be prepared and your connection will likely be more stable if you're coming from a DOCSIS 2.0/1.1 modem. HAPPY SURFING!

I had a lot of trouble with this modem but it's unclear whether it was the modem or my internet provider.

Had this modem for some time but noticed netgear Blackhawk provided me with better signal.

This piece of junk does not work with comcast/xfinity.

This modem doesn't have the power I'd expect. I would recommend a different kind.

Worked fine at first, now I gave to power it down, and back up for it to work.

I upgraded my modem to match Cox service specs. Running decent but not the best

Works as needed but if you plan on some heavy loads upgrade to a stronger modem

Not sure how good it is. After start using May be my speed went low I guess. So I m confused.

Since I have installed this modem my internet slows down and I 100mbps

I wouldn't recommend this, I got one earlier and it worked just one year.

The product is good but I am dealing with the conecction, sometimes the internet is weik.
