SB6183 | SB6190

My SB6190 modem started to randomly restart and I stopped using the device. I would like to submit a warranty claim but the website failed to identify registration number and model to get warranty status. I then I tried to register the product and save issue. The website failed to identify registration number and model again. 

My modem keeps losing connection the last two days sporadically. I have had this modem for 4 years with zero issues and all of a sudden now we cannot hold a steady connection. ISP (XFINITY) tested connection to my home and said everything looked good except modem wasn’t online.  we have changed cables and unplugged and power cycled. Do we need a new modem or any other suggestions? What’s odd is it will not work for several hours then come back and work for 8 hours then again not work. 

My SB6190 just suddenly and abruptly turned off. Even though it is plugged into a working wall outlet, it cannot turn on.There a warranty?

Can’t connect my device on the app

Is the SB6183 compatible to the Arris app?

Any downloaded software for a PC computer running Windows 11?

Hi everyone, Is there a way I can change the Security on my Arris Modem from WPA 2 to WPA 3?  I already did it on the TP link Wifi router.   I’m not even sure if I can do it on the Arris modem.

I have been having issues with my SB6190 rebooting on its own lately.  It has been a great modem for a long time, but all of a sudden it is acting up.  I admit up front that I am not very tech savvy.  I know just enough to be dangerous.  I have read through various articles and one of the common things to try is to see if there is an update for the modem.  However, when I type in the IP address, I only get an Arris page with information on it, and no place to login.  I can go to a few tabs like Information, Configuration, etc., but none of them have a place to login.     I have tried starting the IP address with https, http, and just the number itself.  Any other number besides 192.168.100.0 just gives me a timed connection failure.  The 192.168.100.0 takes me to the Arris page I mentioned.  I am hoping someone might be able to tell me where I can find the login page now.  Thanks in advance for any help!

Not sure where to ask this question or if it should be a Question or a Conversation?? Either way, will try the General question forum. I had very slow upload speeds (SB6190) so when the Cox Communication Tech came out he replaced the entire cable and connections from the side of my house to the outside pole. I also had rebooted/reset my modem (a few times by the book) and removed the wireless router.  When he tested the system afterwards he said:You’re getting 32 good channels (or ?frequencies) down but only one channel/frequency up and that I should have four channels/frequencies up (SB6190)  I now have good up and down speeds but still wondering, does anyone know the answer as to why only one channel up?  

I have xfinity and they stated there's nothing they can do on there end. Lights as follows and are all solidWhite - powerRecieve - greenSend - greenOnline - white It's a refurbished model, so im not sure if the mac address is linked to another account or if its defective. Didn't try connecting a laptop because online light isn't showing internet coming through. Any assistance would be greatly appreciated.

Modem has been working well, today though I cannot connect to the internet. Power icon is green, the second is flashing green, the other 2 are dark. Have rebooted multiple times, no change. Wondering what else I can do. 

I have a SB6190 that’s maybe ?6 years old with COX Cable internet service.My download speed was around 90 MBPS when I had it routed through/to the wireless routerbut I had close to 0 upload speed (would vary between 0 to 0.1 to as high as maybe 2 if I was lucky). I then disconnected the wireless router and connected the Ethernet cable from the modem directly to the computer and the download speed went to 250-270 MBPS !! but the upload stayed very low, somewhere close to 0 or 0.2, rarely above 1-2. The speed I’m paying for is around 250 down so I don’t think I’m overtaxing the modem which is ratedat 1000/1000. This all started about 6-8 weeks ago so I had COX come out and they replaced a connection at the house and the cable all the way to the pole and to the junction or distribution box at the top of the pole.  I don’t know if they replaced a connection at the pole or the whole box.  I live near the Gulf so the connectio

I have an older SB6183 and while it does everything that I want it to do from a performance standpoint, it stays constantly hot.  It has plenty of room around it for airflow and it is shocking how hot it stays.  There are 5 of us in the house using wifi, so maybe that plays a role, but I’d like to have something much cooler sitting near me on my desk instead of this hotbox.   Do any modern modem offerings stay cool?  There has to be a better option. 

One year later, can you provide an update on this?  @SURFboard Moderator  ​@SURFboard Moderator ​@SURFboard Support SB6190 403 Forbidden | Community“Once that firmware was pushed to the unit I was no longer able to access any management functions and the exact same issue as the prior unit surfaced.

Using www.arris.com/consumersupportI can't register my SB6190 because submitting the form results in the erroneous"The serial number and the model number that you entered, do not match"I made no typographical error; this happened on each of 3 different browsers.  Doing it over the phone or in a community forum is a bad look for a technology company. Ditto that this is a long-known issue.  What's the solution, please? 

Keep getting laptop invaded how to do I find address and stop it?

I can’t activate my modem. The power light is steady green but the one underneath it is blinking green only. i have tried restarting, resetting but it won’t work. 

HELLO!  WHAT ARE THE STEPS TO GET A QR CODE THAT GUESTS CAN SCAN IN ORDER TO ACCESS THE OPEN/PUBLIC WIFI?

It isn’t listed on the modem and no product specific labels were in the box.

how to determine manufacture date of sb6183 

I keep getting these messages on my cable modem event log. How can I fix them ??? Sun May 18 04:44:12 2025 4 DHCP RENEW FAILED - Critical field invalid in response Sun May 18 10:03:31 2025 3 No Ranging Response received - T3 time-out;CM-MAC=5c:e3:0e:3b:96:03;CMTS-MAC=00:01:5c:ac:a8:7a;CM-QOS=1.1;CM-VER=3.0;

I have a SB6183 cable modem that I’ve been using with a NETGEAR R6300v2 router that’s worked great until a bad thunderstorm came through and did something to my internet/wifi. The technician said I need a new router. I connected a NETGEAR AX1600 WiFi 6 Router and it didn’t seem to fix the issue. Should it? Any router recommendations that would be compatible with a SB6183?

SB6190 not approved by Spectrum but packaging says it is. Is this a spectrum issue or false advertising!

How can I reboot the SB6190 remotely?  I’ve owned surfboard modems in the past that I have been able to reboot via the web interface, but I don’t see the option there for this modem. If not through the web interface, can I SSH or telnet into it?  My cable provider can reboot it remotely. Thanks,Justin

I’ve had a SB6190 that was working fine for more than a year. A few weeks ago, it started rebooting itself multiple times per day, but once it rebooted, it reconnected to Xfinity just fine. Unfortunately, it would just do it again in a few hours, and obviously, internet service is interrupted for about four minutes each time.Xfinity sent a service tech, who checked and said there is nothing wrong with their cable. He said the SB6190 should be fully supported on the Xfinity network, and suggested I buy a new one. I did buy a new one, and it behaves exactly like the one that is more than a year old. It works fine, until it reboots itself, and it does it just a frequently as my original SB6190. What do I telll Xfinity, since it’s obviously their network? Two different SB6190s (both tested when plugged into the wall and also tested when plugged into a UPS/surge protector) are acting identically.  In addition, there seems to be two entries in the logs that correspond to the
