Review on ARRIS SURFboard SB6190 DOCSIS 3.0 Cable Modem, Compatible with Cox, Spectrum, Xfinity & others (Black) by Coby Hall

I want to echo and agree with other reviewers: SB6190 only! I bought the SB6190 a little over a year ago and have just bought the SB6183 to replace my broken unit. The SB6190 ran for about 13 months without any problems and during that time I had no downtime. The modem was in a ventilated back room in my house, mounted on a wall with more than adequate airflow. For the last month my internet started dropping constantly and then disappeared. Somehow my 150Mbps connection couldn't stream 360p video to my Chromecast and connection timeouts were frequent, although the connection always reestablished after a few minutes. It took Xfinity Customer Support a few hours to trace the problem to the modem. . Since the modem was able to connect and respond to the Xfinity signals, we were under the impression that the problem was with the Comcast line and we spent quite a bit of time setting up service appointments to ensure that the Comcast connection wasn't the problem. It was only after an Advanced Support specialist was called in that it was revealed that the modem was to blame. Hours are wasted. I did a little research and found a lot of complaints about the SB6190 - it's a buggy device and the Puma chipset is at the root of the problem. The question is not "if" the block will fail, but "when" the block will fail. I have no idea why Arris keeps sending defective units with all the negative reviews online. I also think it's a little iffy that the SB6190 is listed on the same page as several other models. When I bought the SB6190 I saw the strong Revain rating and assumed the rating was for the model I was buying and not the range of models. Reading the test page, it becomes clear that there are many issues with the SB6190. As I bought this unit 13 months ago I can't take advantage of the 1 year warranty and bought a cheaper SB6183 with much better specs. Very disappointing and I hope my new SB6183 will be more reliable.
