Bests & Worsts Reviews from Amazon

Initially, the modem worked great. I was getting over 135 mbps download, I normally get about 100 mbps beofre the 'upgrade.'. After a week though, the speed would drop to less than 2 mbps. I would have to reset the modem and the speed returned to 130 's again. This went on for a couple weeks. At first, it was daily, eventually every 2 -3 hours. I contacted ARRIS customer support. They ran some tests on the modem and assured me my modem was fine and passed the blame onto the cable provider. I had several technicians from cable company come out to trouble shoot. They ended up replacing my line from the main box in the street to my box on my lawn. Then, the line from the box on my lawn to the box on my house. Eventually replacing the line in my house upto the modem. They also replaced the components in these boxes. After about the 15 visits and 2 months later, with the cable company insisting that it was a problem with my modem and ARRIS insisting that it was the cable company, I listened to my wife's advice. I hooked up my old sb141 modem. Now I am getting 140 mbps downloads consitently. ARRIS has managed to drag this along for over 30 days so I can't return the modem. On a brighter note I have brand new cable lines run from the main box in road into my house. I have been a strong supporter of the SURFboard modems for 4-5 years, starting with the sb121, then the sb141 and then sb 161. I have never had a problem with them until the sb183. The sb141 was probably the best modem they made. Product quality have suffered since they were taken over by ARRIS. Customer support is disappointing. If you own the sb141 keep it and don't waste your money upgrading to sb183. If you are looking to buy a modem, get the sb141 and hope that is does not break, because ARRIS does not stand behind their product.. Or go with some other company. Please that once the cable company replaced all of my lines, the sb141 was as fast as the sb183.
