No longer manufactured by Motorola JD Hayes Recently I have started to replace the search for a modem for my aging Motorola SB4100. Because of the good reviews, I decided to buy the Motorola SB5120. Unfortunately, I found the SB5120 very hard to find (Amazon does not have it in stock at the time). The SB5101 was, but now everywhere for about $ 50. In frustration, I contacted Motorola to ask questions about the availability and the significant differences 5120-5101. The Motorola technician that I spoke to told me the reason 5120 is rare, 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. . Service] was flakey so I called Comcast to come out and see what was wrong. He replaced the modem with an unnamed starving and I saw my download speed drop of 4 Mbps to 1.2 Mbps! Caramba! I called their technical again and asked him what happened. His answer: ". The table looks good, you can not trust websites speed test (dslreports in this case) and modems do not make any difference in speed" Yeah, right. I immediately bought the surfboard modem, replaced the no-name, called Comcast to the MAC address and it was 1.2 MP download immediately before the output switch the modem was happily over 4 Mbps and a completely stable connection! Cable modem makes a big difference and it is good! 60 of 62 people found this review helpful. Fast, reliable, better than the Linksys integrated by the engineer using the SB5120 to replace Linksys BEFCMU10 (version 3.0). The SB5120 works better and is much more stable. I had problems with performance and reliability of VOIP service on my cable modem Linksys Under load the Linksys cable modem has high latency and working properly. Linksys cable modem required a reboot a few times a week. (Note:. No problem with my Linksys VoIP router) with my VoIP connection SB5120 sounds better and is more stable (without rebooting cable modem is required). My total latency is smaller and web pages load much faster. The packet forwarding performance is much better with the SB5120. See all 253 customer reviews ....
