SB6183 | SB6190

My SB6190, connected to Comcast, has worked well for the past couple of years. There were the occasional Comcast outages, of course, but now I am unsure if the problem is Comcast or the modem, since the problem is always cleared up by power cycling the modem.  This started about 2 weeks ago, and occurs daily, sometimes twice a day.  Below is the event log from today.  10:11 and 16:50 are immediately after the modem is rebooted.  Any thoughts on whether I have a hardware or internet provider issue?  Thanks in advance!! Tue Jan 02 01:14:51 2024 5 RCS Partial Service;CM-MAC=[removed personal information];CMTS-MAC=[removed personal information];CM-QOS=1.1;CM-VER=3.0; Tue Jan 02 02:51:43 2024 3 No Ranging Response received - T3 time-out;CM-MAC=[removed personal information];CMTS-MAC=[removed personal information];CM-QOS=1.1;CM-VER=3.0; Tue

SB6190 modem not working. no lights working. Bought new July 2023. It is still under warranty, please replace! thanks

Frustrated is not the word!  SB6183 Arris should have more customer support than this.   Signal won’t hold-  drops internet connect every 5-6 seconds and reconnects every 10 seconds. New place, new internet connection, new company.  Signal good from pole to house.  All wires have been checked multiple times, power cycled many times, still happening.   

I just got connected to xfinity internet today with my new SB6183. When I directly connect my computer to the modem, I connect to the internet just fine. When I connect the modem to my wifi router, nothing. Do I need to update any settings in the modem prior to connecting my router? Or is this just a router issue? The router was working just fine 10 min ago connected to my old modem.

Is this easy to set up from Xfinity

My ethernet port on my SB6183 doesn't work. I try to connect it to my laptop and it just doesn't connect. I'm not sure exactly what to do as the wifi works fine. Any help is greatly appreciated!

Is this a modem issue or a provider issue ?  POwer for upload bonded channels is approx 36.50 dBmV for all four channels as reported by the Modem home page.  Will getting a docis 3.1  modem help or is it just a provider issue. and voltages will also be low for the new modem. Currently I cannot get higher than 12 Mbps upstream

Just moved about 15 min. away, but am in a new zip code. I've plugged in both the modem and the nighthawk router, but I am not recieving internet. I thought it might be an issue on the service provider side of things, so I contacted Xfinity, and they transferred services. However,  I am still seeing "connected no internet" on my devices. Need some troubleshooting help. 

Totally ignorant about wifi/modems.  Can you recommend a good extender for use with my SB6190?  Trying to serve a 4500 sq ft house on two levels.

I went to Xfinity and after a lot of troubleshooting they said that my surfboard docsis 3.0 cable modem (SB6190) came up as flagged for the reason for why my internet was slow and everything was good on their side. What could be happening with the modem? 

Xfinity cannot connect w my surfboard modem. Says it already registered to another customer and I should return it to Arris. Suggestions?

Does Arris have a phone number to contact their support?

Wi-Fi goes off at night unplug the system plug back in dosent come back 

I am currently using a 3 yr old SB6190 modem with AC1300 Linksys mesh routers(3).  Over the last 8 months, I’ve been experiencing intermittent internet loss lasting from 15 sec to 5 minutes.  These occurrences are most notable when streaming music through SONOS or viewing videos on YouTube, and also while on the internet using my iPhone. The modem is DOCSIS 3.0.  I talked to xFinity and all is good on their end(according to them).  After investigating, I understand that the problem MAY lie in the fact that xFinity has switched to DOCSIS 3.1.  Would the switch cause constant internet interruptions?   I’m trying to understand whether it’s the modem or the routers that are causing these issues.

I currently have WOW service and need a new modem. My current plan is 200 download and 10 upload. I can get an SB6183 sealed unit (black - maybe this is older?) for $20. I have a Black  Friday deal on the SB8200 for $98. Is the SB8200 worth the difference since I’m limited by my plan speed anyway. I do tend to keep my modems for some time. I had my last modem for 9 years. I’d like to hear opinions. Thanks. 

Switching internet account from previous owner of property to mine with the same modem but internet provider (comcast) cannot activate my new account remotely, although the internet data shows normal on from their end. 

The box has no information on wifi name and password I can’t set up without putting that information in his

My SB6190 has intermittent drops throughout the day.  I just bought/activated it 3-days ago.  My service provider is Spectrum.  I work from home and cannot have this happen so frequently.  Please help.

I cannot find the admin and password name

I can’t find my network SB6190

Internet is still not working

I went to upgrade my modem and bought a brand new Arris Surfbord DOCSIS SB 6190 to replace my old modem only to discover when I got home that I had bought the exact one again-same exact product with same model number. I know this is a dumb question but am I to assume that because what I just bought at Walmart is new that it’s components inside WILL in fact be an upgrade since it’s a new one? I mean when you replace a modem you want the latest technology and components. 

Is says SB6183 on the modem, just curious to as why this would be.

Xfinity internet did some recent updates to the service and after that my internet is no longer working. My devices do connect to the Wi-Fi and xfinity says my modem is online however it keeps saying no intervener connection on all my devices. 

The warranty period for my Arris  SB6190 modem is until March 29, 2024. Yesterday it just stopped working. How and where can I send a faulty modem for replacement? The link to support from previous responses to comments is not active.
