Amazon Renewed ARRIS SURFboard SB6190 DOCSIS 3.0 Modem

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.

I purchased a renewed ARRIS SB6190 to replace my CISCO DPQ3212 from Cox. The SB6190 does not have built-in support for a telephone jack – it is internet only.
Activation with Cox was easy. I gave them the model, serial number and MAC address and was connected in a few minutes. The only thing that changed on my end was the modem. I used all of my existing connections in the exact same location and my speed (up and down) MORE than doubled from my Cox provided modem. Good bye rental fees.
I purchased this as a renewed modem and it has thus far worked flawlessly. It looked new. There was no visual evidence of this being a used modem. I would recommend this to others that are looking to stop renting from Cox.
The SB6190 does not support the gigablast speeds according to the Cox website. My speeds are consistently above 100mbs down and 10mbs up (picture from most recent test attached). My service is Internet Preferred 250. As you can see from the picture, there are times when I am able to get above the 250/10 speeds that the plan quotes.

The slowest part of the setup was calling in to my ISP to have them activate my service with the new modem. This is super easy to install and works flawlessly.

my wi fi from Xfinity supposed to be included but couldn’t get rid of the rental charge I got sick of calling them purchased this one – works like a dream and its faster then one which comcast provided, thanks

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**
