      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.

        Very Easy to Install and it took only 5 minutes to contact my cable provider Comcast and they had to send a Signal back to the modem for it to work. Saves me $ Rental Fee/month for the Cable Provider so in a year it will have paid for itself.

        I purchased this modem to replace the leased modem from my Internet provider, Time Warner. Setup was super easy. Just connect it per the included instructions, then contact your provider to activate it. You'll need to give them the modem's MAC address, so make sure that's handy when you call.

        The 1 Gbps LAN port is a nice benefit to this device.

              Comments about Motorola SB6141 SURFboard DOCSIS 3.0 Cable Modem:

              Beginning Jan 1, 2015 my cable company started charging $/mo for the use of their cable modem for my internet. Purchased this slick Motorola modem from B&H and a few days later; saving that $/mo. To install, had to call the cable company, speak to a rep so that they could get the MAC address from the modem and "switch" the service over. They also wanted to know which Docsis version the modem was (this one is Docsis 3.0) It is every bit as fast as the cable company modem. I have seen a few complaints somewhere about the extremely bright blue lights; and they are. This is not a problem for me; just put something with a cloth near the front to block the lights(DON'T cover the modem; electronics need to dissipate heat). They will make it easy to see for maintenance and troubleshooting, if necessary. I've only had it about a week and it hasn't dropped a signal one time, to my knowledge. I would definitely recommend purchasing.

                          I really liked this modem. It's fast, small and very capable. Make sure you have an wireless router if you have more than one computer at home. This only has one ethernet out and has no wireless capabilities. It worked for me because I already have an existing network and just needed to upgrade the modem itself. If you're starting from scratch, make sure you're aware of what you are getting and what else you will need for your network.

                          My modem failed and the online consensus was that the Motorola SB 6141 was fast and rock-solid. B&H got it to me very fast and it I was up and working immediately. I recommend this product.

                                4 stars for easy setup, super fast. ran speedtest with two TW install technicians when i asked to replace the modem they tried to force on me with this one and they were shocked at the speed results, which were markedly better than the modem they were offering. TW just upped the speed in my area by 6-fold so we will see how "future-proof" this thing really is. I suspect it will be stellar! highly recommend

                                I was with Comcast for few years until last year I switch to ATT. When I use Comcast, I rent their modem for $/month. I'd been replace the modem 3 times due to varies problem. They always give me a old model modem. I have to reboot it every other week.This time I come back to Comcast I decided to buy myself a good modem instead of keep paying the rent. I'd been using this one for more than 3 weeks but never did a reboot. My plan is 50MPS but I always get 56MPS. I'm very happy with it.

                                  Quick and easy setup. Bought the standard Surfboard modem (without built-in wireless) since TMobile is currently offering its subscribers a free Asus wireless router ($ Deposit). Solid fast speeds and haven't experienced any drop or connectivity issues.

                                    Bought this to avoid paying rental to comcast, whent hey wanted to upgrade our modem to their WiFi version and give free WiFi to neighbors. took a bit of doing to get it working (The online activation on Comcast website didn't work, so we had to do a phone call.. and the person manning the line was not all that savvy), but once we got it working, it's working flawlessly.

                                      Modem was easy to set up with call to my cable service provider. I have no complaints about the performance and BH Photos price and shipping were great. Not so thrilled with the white case color. Be aware that the status lights are really bright. Kind of like the sequential landing lights at an airport. Had to turn the modem to face the wall to alleviate that feature.
