    Improved speed by about 10% I'd say without upgrading my cable service. Got this to replace the old modem which was starting to drop signal more frequently albeit it was more than 5 years old already. It's placed in our living room and isn't really a problem being too bright but if yours is in a bedroom it can be quite bright so keep that in mind. Still I would highly recommend this to a friend!

    This is an excellent modem—though it is rather expensive. I guess it is better than renting from the cable company.

    The bright blue and green LED lights on the front panel are extremely bright though and light up my whole living room at night. I tried covering them with a piece of paper, but they went through the paper and continued to light up the room, so electrical tape it is. There are a number of ventilation holes in the case which also leak a ton of light. Unless you can hide this device in a drawer, be forewarned of the lights.

          Comments about Motorola SB6141 SURFboard DOCSIS 3.0 Cable Modem:

          I purchased this modem to play online multiplayer games, where latency is important. This unit did not disappoint, with super fast speed and most of all, reliability. There is always a steady connection, with no dramatic changes to my ping.

          There's really nothing bad to say about this modem. Set- up was quick and simple, and the unit doesn't run that hot, like my last modem did. Overall, I would recommend it.

            The best part was buying through B&H - alwasys the top vendor.

              The error was on my end. I got this for a client and forgot they are on a business account. TW Cable and Comcast as well will not let you bring your own modem in for a business account and I forgot that fun little fact. I did how ever do a ton of research and for home systems this is supposed to be the bomb diggity so ... buy away... also returning the item was pretty easy which is why I buy from B&H Photo.

                Purchased higher data rates from Comcast and wasn't getting the rates I was paying for. Read that your speed depends on the weakest link, so before I contacted Comcast I decided to look at my own equipment first. Swapped an older Motorola modem for this one that touted faster data rates. They didn't lie! It's proving to be reliable and fast. Router is next!

                              I purchased this modem after I connected my cable internet service with Wavebroadband, shipment was on time, modem got connected with no problem after I called my internet provider to register the new mac address, I am getting 109 MB per second and service provider is advertising 110 MB. So far it is good and price was cheapest from B&H.

                                I am now able to get the full bandwidth that I am paying for. It was a flawless transaction through B&H and very fast, AND FREE, shipping. I will definitely be shopping with B&H again.

                                  This modem was quick and easy to set up. I use comcast and I don't know why I didn't buy this earlier. Very intuitive and don't even need to read instruction to set it up. Very good.

                                      I am so glad this was available. I had rented one from my cable company for years...AT $[$]/MONTH! Duh! Have made many purchases from B&H. All of these have been great experiences. Great customer service, fast shipping and top notch products. Oh yeah...best prices! Thanks B&H!

                                        I'm an unfortunate soul his forced to use C**cast as my internet provider—no other options. Not only do they lack quality in their level of service, they also lack quality in the hardware they provide. In addition, it makes no sense to pay a monthly fee to rent their second-hand garbage. Nonetheless, I had been doing that for quite sometime. C**cast was unable (or unwilling) to resolve any problems—constant disconnecting, slower than slow speeds, etc. All my friends told me to get rid of the modem they provide and replace it with this Motorola. So, I did. Couldn't be happier. I have been using this modem for a few weeks now and have experienced no issues whatsoever. Dropping my connection, slow speeds and "resetting" the modem were once daily occurrences with the gear they provided, now I haven't experienced any of that nonsense. Buy this modem, it's worth the piece of mind (not to mention the savings you'll get on your cable bill).
