ARRIS (SB6190-RB) – Cable Modem – Fast DOCSIS 3.0 32×8 Gigabit Cable Modem, For Comcast Xfinity, Cox, Spectrum and more, 1 Gbps Port, 800 Mbps Max Internet Speed, 1 Year Warranty – Renewed

Works with XFinity, speeds are what I expect. Not trivial to setup with a Wifi Router.
I dislike “renting” HW from a internet supplier. In my new place, Xfinity was my only option. While I had problems with Comcast 10+ years ago, with no other options I was hoping things had improved.This modem works exactly as expected. When Xfinity came out to setup my service, the modem came up and I was able to plug in and get internet access with the tech here. Simple. One ethernet port and no Wifi, but a good price.However, I wanted to use my slightly older Netgear Nighthawk D7000 Wifi-Router as my primary connection into the house. It took calls to Netgear, Arris, and Xfinity before I found the right set of steps to get everything working. Not well documented, and none of the helpdesks could do much to get me working. While I reset things so many time across two days, I believe the right steps were:- Arris up and working (can see internet with a hardwired PC)- Cable from Arris to Nighthawk “Internet/Wan” port- Cold boot router- PC to ethernet port on router- Navagate to 192.168.0.1 (Nighthawk admin page)- Netgear Genie comes up, let it do its thing (10+ minutes)I had to have everything up before I could use 192.168.100.1 to get to the arris modem page, but it turned out that this modem is simple enough that the only thing I did when I got there was turned off all the the LEDs (blue and bright).I would hope other routers would come up easier. 5-stars for the modem (after the setup pain). I’m getting full speed and things have been solid.

Works well so far
I purchased a refurbished unit to save money and my two concerns were whether or not it had truly been refurbished and not just resold, and second was that I would have a hard time registering it with Comcast as it might still be listed under Comcast as in use by someone else.It turns out that I did have difficulties getting it connected to Comcast but not for the anticipated reasons. To set up a new Cable modem the Comcast process was that I download an app to my phone and follow the procedure in the app, which was where I entered the MAC address of the new modem. But the app failed to function properly and I had to pay bloody hell trying to work through Comcast’s support system.I worked as a lab assistant at Scientific Atlanta back in 94 &95 when this stuff was being invented so I knew exactly what needed to happen to fix the problem but I had an extremely difficult time getting in touch with someone who could do what I asked. At one point Comcast wanted me to wait 3 days for someone to come out to may house and fix the problem. At which point I was nearly yelling at the Comcast people trying to get them to work outside their troubleshooting “menu”/”flow chart”.Once I finally did get connected to a person with the appropriate skills/knowledge the problem was resolved in a couple of minutes. The modem has performed perfectly ever since. I hope it continues to do so for years to come.I can still get a little upset at the Comcast person who insisted that I should wait 3 days to have a service person come to my house so I could finally have a working internet!!! **UNBELIEVABLE**

Four stars because it took Xfinity about an hour to provision it.
I’m on a limited budget. Gut I got a faster speed from Xfinity at a lower price so a new modem was needed.I got a “renewed” unit at a good price. I’ve been dealing with networks since 1988, so I’m not unfamiliar with the process.I did the heavy lifting on my end, which wasn’t very difficult at all. Anyone with even a modicum of experience with home networking will have no problem. Some people say the phone app is a pain, but it did help.Then on to the Xfinity app. After three attempts and waiting for an hour I called support. I got a pretty nice person who was well versed in setups, and even he had a hard time provisioning it, but after about 50 minutes I was able to log into the Xfinity site.I’m not quite getting the speeds I should be, but I also have my network locked down pretty hard. But I can run 3 TVs, two devices running the SXM app, and browse with no glitches. If it had provisioned with the Xfinity app, it would have been 5 stars, but there hasn’t been a modem yet I haven’t had an issue with Xfinity, including their own.
