Solved

We have a ARRIS G36 modem, with a 1 TB home coaxial connected  Xfinity link going to it. During every conference call, I either lose the connection, freeze up, or have generally bad connection. The modem is 1 year old, I am directly connected to it via Cat5E cable, there are 3 other devices connected wirelessly, what could be the issue???

I just purchased a SVG2482AC Surfboard. I have Xfinity internet with voice. They told me it is not compatible with my internet.

Out of nowhere, I got kicked off all my devices and my wifi just disappeared. Though, okay, maybe I should just reset it, but when I try to do 30-30-30 factory, nothing happens. Any ideas? 

Do firmware updates take place automatically on the Arris SB SBG7400 or is there something that I have to do to make this happen?

How do I turn off the wifi on the Surfboard modem/router combo?? We are installing the eeros mesh system. 

I believe there is more than one issue going on. But this is what I know. I lose connectivity both wired and ethernet. sometimes for a second, sometimes for minutes. The lights on router onlly sometimes change from blue to orange during this. I had seen aquite a few Event logs not sure what to make of them. Every check of Qam shows in parameters. I dont know if these logs can give some guidance. I am a remote WFH rep and need stable internet I bought this modem router for the 4 ethernet ports and wifi 6. We are a 3 person sometimes 4 person family. Son’s a gamer, We have Amazon devices and Cameras and Streaming SErvice not to mention phones, tablets, ets… Average about 30 devices at any given time. Please help. I dont understand how to read the analyzers or if I need to change something like a channel…No Ranging Response received - T3 time-out;CM-MAC=d4:6c:6d:3a:2a:89;CMTS-MAC=00:01:5c:8c:dc:62;CM-QOS=1.1;CM-VER=3.1; 04/10/2024 23:17:32 Critical CM-STATUS message sent.

We have a previous wifi extender - TP Link that was easy to connect on our old router/modem as the old one had a button to connect it. This new surfboard does not. How do I connect this wifi extender now??

I signed into my guest network and now I'm unable to get out of it and back to the normal network (not guest). Every time I try to sign into the not guest network it's saying wrong password, which is not wrong. This all came about from me struggling to connect my blink camera system, which failed miserably. 

Before I buy the S33, does the Eero 6+ router/extenders work well together?

Not sure what’s going on but some connections to my home network are forwarding to an external captive portal site - connectivitycheck. I did not set this up. How do I stop this from happening? This is not a wifi hotspot - it’s my home network. Not every connection gets forwarded to the external site - only some of them. And this is not a wifi problem - the wifi connections in the router are working fine. It’s some of the ethernet connections that are getting forwarded. I know they are connected to the internet because they are bringing up that external page, but they show as not connected because that captive portal appears to be blocking the connection. I am on Xfinity and the external connectivitycheck captive portal is bringing up an xfinity login screen as if I was on a wifi hotspot, which I am not. But again, the wifi connections and some ethernet connections are working fine. And all connections show as connected via Advanced IP Scanner even if they are blocked by the portal.

Tech was here today and eliminated everything but the modem I got yesterday. So I go to Best buy and swap it. Get home and this modem has exact same problem (that's 2 new failures in a row). I can't expect that kind of new-bad rate from Arris, can I?

Two questions actually: 1. How do I change carriers on my surfboard 7400? 2. My adult son turned the lights off on the 7400 so how do I turn them back on?

The bottom of the model provides WAN & HFC, but not CM. I need this to activate my WiFi through Xfinity app. 

My modem just stopped working randomly. I restarted it multiple times. I tried resetting it by pushing the reset pin up to 30-60 seconds, but the white light never changes. Is there usually a visible confirmation that the reset worked?I finally had a comcast technician come out and I am using a rental modem.But just in the off chance somebody knows the problem, please help. The white light stays on and never changes colors. Also, can we ship the rma back in the original retail box only? It is pretty well protected in the retail box.

i sent in a request for help.  I can’t find how to get a live chat again, the page just says it’s open.  Also, this modem is driving me nuts!  It doesn’t work and I’m past the time for returning it to Amazon.  HELP!!! how do i get a replacement of a different model?  Too many people have this problem for it to be my problem.

On the G54, can you manually set 5 MHz to a specific channel?

my building is looking into an arrangement with Frontier to install FIOS in my building. We currently have xfinity and I have an ARRIS G36 modem. Its is working rather well now so I wondered if I could keep it if and when this building goes over to  FIOS. I can’t get much of an answer from ARRIS and after a long hold, I was able to speak to a tech service person at Frontier, who told me that the only modem compatible with their FIOS is the ARRIS NVG443B. But that one isn’t even listed on ARRIS’s website. Anyone know anything?

G34 ipv6 setup 

internet quit working suddenly on surfboard SBG7400AC2. Never have had any issues until tonight.

I have a Netgear router with ACCESS CONTROL turned on but NOT blocking new devices. My S33 modem seems to have valid connection lights (solid blue) but none of my wifi devices have internet access. Connected/No Internet. Everything works fine with my older cable modem….

I am trying to install my new S33 modem however it is not an option in the app for installation so I don't know how to set up our modem 

I’ve been using an old surfboard modem with google wifi mesh for years but never seeing speeds over 150mbps. Xfinity told me this was because my modem was outdated and couldn’t support higher speeds, which by the specs is probably true. so I upgraded the modem to the s33. With speed tests, I was now getting 800mbps at the modem (what I pay for), but my WiFi was still topping around 200mbps on devices nearby. I decided to ditch the mesh altogether as my house is not that big, and got the g36 modem/router instead. Now on 5g, I’m getting WiFi speeds between 350-450 when near the router, down to 80mbps two rooms over. On 2.4g I’m getting 40mbps max. Is this really the best WiFi speeds I can get with the g36? 

I have pressed and held the button in the little hole and waited until lights go out.   Then waited until it came back up.  I have internet access, but the login on the SBG10 is not being reset after multiple attempts.  I read about a suggestion to reset the gateway, but do not see directions on how to do this.

Furious customer here!! For several MONTHS I have been battling with Arris for a refund for a modem that failed within one year of use. They refused to refund, as the product was not purchased directly through them. (A very unfair policy that leaves most consumers at a loss, as most merchants will not accept faulty tech merchandise and will just tell you to contact the tech company directly).So, they sent a replacement instead. This sadly failed to work within ONE week of use! Clearly there is a problem with their products (as I’ve now seen from lengthy searches on this forum and online, including a class action lawsuit in 2017). There seems to be a significant number of issue with their products and compatibility with Xfinity.Compounding this, the customer service experiences I have had have been HORRENDOUS, including empty promises to return calls; no direct line offered to the senior rep, Priya, I have been fruitlessly working with, requiring a minimum of 30 minutes per call as juni

Purchased a S33 V2 but when I login to the Arris portal it states that the hardware version is V1.0.  Do I actually own a S33 V2, or did they put a V1 in a V2 box. I searched this issue, and the only answer seemed like a canned response from the manufacturer saying they source components from the same places - this is not an answer to the question being asked.
