Review Motorola SB5120 Surfboard Cable Modem Docsis 1.1 and 2.0 Certified USB
Recently I started looking for a modem to replace my aging Motorola SB4100. Based on the good reviews, I decided to buy the Motorola SB5120. Unfortunately, I found the SB5120 extremely hard to find (Amazon did not have it in stock at the time). The SB5101 however was in stock everywhere for about $50. Out of frustration, I contacted Motorola to ask about availability and the significant differences between the 5120 and the 5101. The Motorola technician that I talked to told me that the reason the 5120 is scarce is that it is no longer manufactured. He also explained that the difference between the two modems is the internal chipset. The 5120 is a TI and the 5101 is a Broadcom. He also said that there is no difference in performance; both are capable of 38 Mbps downstream and 30 Mbps upstream (limited by the cable company's tiers and number of users on the net).
Finally, I asked him which he preferred (since I could still track down a 5120 if I was willing to pay enough...). He stated unequivocally that he preferred the SB5101 and the Broadcom chipset. He also stated that the speed on the modems is artificially capped by the cable companies so that they can sell tiers of service. This modem, he said, has a lot of available overhead so as the broadband companies compete and raise their level of service,...........................

Very easy to install. You have to contact the internet provider with the new MAC number on the modem before you disconnect the old modem. Once the provider updates the system, just replace the old with the new, connect the cables (power, cable, ethernet to router or computer) and done. No software to install or configure.
I have this modem working for about 3 weeks now, without any loss of service. Before I had a 3 generations (DOCSIS 1.0)old Cisco Linksys and I had frequent disconnects and had to reboot the modem once/twice a day. I have this modem matched to a CISCO E3200 wireless router and they work great together.
Highly recommend this modem. The seller service was great too...................

Review MOTOROLA SURFboard Docsis 3.0 Cable Mod - 575319-019-00
READ FULL REVIEW>>>
I've used Motorola Surfboard cable modems for many years. The SB6141 is my third Surfboard, and my first with DOCSIS 3.0 support. One of the reviews I read before purchasing this modem indicated there were performance problems when used together with a Cisco E4200. This is not the case. It's possible that firmware revisions have reduced compatibility issues over time, but my experience has been terrific. There is a known issue with the E4200 where the QoS settings hamper upload speeds. The simple fix is to manually set the "Upstream Bandwidth" value to roughly 1.5 times the bandwidth you expect to see. There are a plethora of speed test sites out there. Select a few test sites and play with the upstream bandwidth setting on the E4200 until you achieve the results you expect. My current service is 40Mbit down and 5Mbit up, and I've confirmed these values both with and without the E4200. I'm very happy with my purchase, and I can kiss my modem lease fee goodbye!...........................

Review Motorola SURFboard Gateway SBG6580 DOCSIS 3.0 Wireless Cable Modem
READ FULL REVIEW>>>>
When evaluating this type of equipment, one must differentiate between the device itself and other factors that can impact its performance. Blaming the manufacturer for issues likely caused by one's ISP is akin to saying, "I can't get past third gear because of all this construction on the highway... I'll never buy a Jaguar again!"
That said, the SBG6580 is a solid piece of kit.
This latest addition to the SURFboard line combines a DOCSIS 3 cable modem with a gigabit switch and a dual-antenna 802.11n wireless access point, providing all the networking equipment a home office needs in a single compact package... this amounts to a single point of failure, but that's par for the residential course. It can deliver 42 mbps downstream on a single channel (which my provider brands "Lightning") with support for eight bonded channels... meaning that when the day comes that ISPs start selling triple-digit speeds, this gateway won't need to be replaced.......................

Review Motorola SB6121 DOCSIS 3.0 Cable Modem in New Official Manufacturer Brown Box (Environmentally Safe) - Non-Retail Box, 100% New and Complete SB-6121
READ FULL REVIEW>>>
Motorola's SB6121 cable modem is one of the best cable modems available on the market right now, if not THE best. It is a full DOCSIS-3.0 modem, but also fully backwards compatible with DOCSIS 2.0 and all the way back to DOCSIS 1.0. In short, it should work on any cable system. It is future-ready with IPv6 support built in.
I bought the SB6121 to replace a D-Link DCM202 which had started randomly dropping the connection several times a week, sometimes multiple times a day. Installation is trouble-free; just connect the cables and notify your cable company. (Have the MAC address from the label on the bottom of the modem handy when you call.) Many cable users report speed gains on updating to a DOCSIS 3.0 modem; I'm no exception -- my download speed went from 11.5Mbps to 12.8Mbps, and my upload speed increased by 50% from 960Kbps to 1.5Mbps.
Interface-wise, there's not a lot to say. The Motorola SB6121's colored graphical-icon LED indicators are much easier to identify and read from a distance than the D-Link's closely spaced row of identical yellow-green LEDs. You can look at it from across the room and see two steady blues and one blinking amber, and know at a glance you're in good shape..............................

Out of nowhere, I was having excruciatingly slow internet speed on Comcast. The Comcast tech advised that my Motorola SB 4100 was at the "end of life" and that I should upgrade. Skeptical, I purchased this modem which is a DOCSIS 3.0 (and backwards compatible) modem. It worked. I went from a 2mbps download speed to over 17mbps. What a difference. There was one installation glitch that you need to be aware of. When you hook up the modem (connect the coax cable, connect the ethernet cable, and plug it in, that's it), and then try to get online, it will direct you to a Comcast self-activation screen (no other site is available). After entering my account number and phone number and hitting the "next" button, I got a blank screen, and nothing happens. So I called Comcast and they said that usually happens if you are doing an upgrade; it mostly works only for a new service connection. However, it is a simple matter to give the tech your MAC address and the serial number. After about 5 minutes, while..................................
