S33 | S34

if this modem supports moca, does it support moca 2.5 or only 2.0?

I bought a s33 modem about three months ago from Walmart. I've been lazy and didn't bother to hook it up but of course I want to now and I can't find the software license. What do I do to get that back?

I just installed a new S33v2 and ever since, I’m getting SSL errors. The cert on the modem itself is bad, not expired but I guess not trusted. But I don’t know why that would have anything to do with certs passing through the device. FYI, all incoming certs appear to come from my SP (Cox) instead of their actual origin. I can ping out but can’t connect to anything using SSL or TLS, which is pretty much everything now. Any ideas? Thanks,Tom 

Cox came out for a tech support visit and confirmed the S33 modem is dead.  How do I begin a warranty claim?   Bought from Amazon in June of 2023.  

For the last few weeks, I have noticed my Arris S33 Cable modem has been dropping the DOCSIS 3.1 connection (solid blue LED) to XFINITY GB service and reconnects at DOCSIS 3.0 (Solid green LED). It’s still pretty fast but I take exception to XFINITY providing LESS service for more $, Is anyone else experiencing this DOCSIS 3.1 drop with Xfinity?BTW, I’m in Tucson, AZ

Arris Surfboard(s) not workingBeen using an Arris Surfboard S33 for a few months now and have had no issues until today.    Came home from work and suddenly it seems like it’s bricked or something.    All three LED (green, blue, amber) indicator lights are lit up, leaving a yellow-ish solid light that never changes or blinks. It’s completely unresponsive and I am unable to connect to the internet.    The lower Ethernet port on the back has lights on while the top one does not. Plugging the Ethernet to the router into either one does nothing and neither does hardwiring my PC into either one.    I know the pics shows the coax unplugged, but that was just to capture the lights easier.  Using a pin to reset the modem does nothing. Tried for 10/20/30sec and no dice.  Title is plural because I went out and bought a second one thinking the original one was just faulty, but upon giving it power, it does the same exact thing.  

Arris customer support is joke!!! No phone number to call. Chat is not available. I have a modem that is under warranty and no one to help me. 

Everyday for the past 4 days around the same time our modem loses connection for a couple hours and has the blinking green light. I’ll attach a picture of the modem page and what it’s telling me. Our ISP is Comcast if that matters. Haven’t had any before this.  

Could Surfboard PLEASE update their iPhone App to allow me to register a second S33 modem (installed at a different physical address and network)?  Right now there is only a very kludgy way to do this (second iPhone, second email address)

How do I connect to Eero system

On both xFinity’s website cable modems section and CableLabs approved modems list is the S34. CableLabs shows a CQ date of 2024. Does Arris have a timeline for release of this modem? If so, I’d prefer to stay with the brand instead of upgrade to a competitor.    

My S33 starts out getting 550mbps then drops to 30mbps within 60 seconds.  Switched to a hard line to no effect.  Repeatable issue.

When will Arris Surfboard S34 cable modem be out for sale at Amazon, Best Buy or Walmart?

Hello,I want my PC to be connected directly to the S33 with the 2.5GB port, while my router mesh system is connected to the 1 GB port.  Based on testing and what I read this is not possible as the S33 will only cater to one connection for because of IP addresses. My question is if I buy say a Cerio POE-PD04S+ PoE Splitter plugged into the 2.5GB port will I be able to successfully connect both my PC and Mesh router to the POE? Appreciate the tips in advance, currently I just have the Router plugged into the 2.5GB port while the PC is connected to the router’s 1GB port. I could possibly test having the router connected to the 2.5GB using its 1GB port then plugging the PC to the router’s 2.5GB but assuming that wouldn't work.

I purchased two SURFboard S33 (sku 1001358) on July 12th and I would like to return one of the modems. How can I begin the return process? My order number is 59908

This is an ARRIS Surfboard S33 DOCSIS 3.1 I purchased about a year ago. It is under warranty still. The pitch makes it impossible to work in the room. I am requesting a replacement. Thanks.

I bouight my S33v2 11/1/2024 on Amazon. In my previous house my xfinity connection seemed to be getting worse over time, and after moving into my new house (6/17/2024) I can barely hold a connection. My modem is connected to an OpnSense router, so I have graphs of packet loss on WAN and they are up to 100% loss on a daily basis.Xfinity techs have been out twice, first to lay a new cable to house, then to replace all internal house wiring to the modem. The signal is great, I thought it would be fixed when they were here yesterday, but packet loss is worse than ever. I even replaced the cat6 cable between modem and router.How do we get an S33v2 replaced under warranty?

Hi,I’ve read the thread with similar title and tried password as well as last 8 digits of S/N, “password” and last 8 digits, caps on Admin and Password and nothing allows me to login.  Just picked up the unit today.  It’s a v2 version if that helps. Thanks!

I’m trying to get support but the model (P/N) on the bottom of the model isn’t recognized in support system.  Serial# field grayed out.

I have just installed the S33 Modem with Xfinity.  I can directly connect to the internet via a wired connection to the modem.The modem, however is not providing a connection to the router.  I have tried several cables.  The router status is telling me that the ISP’s DHCP is not functioning properly.  Xfinity is telling me there is nothing they need to do, but the issue is between the modem and the router.Are there specific DHCP settings that need to be set up either on the modem or the router?  The Asus Router I am using is the GT-AX110000.

After just over a year without issue, I noticed my S33 has started making some high pitch noise after a reboot for the past few weeks.  I checked that it wasn't overheating, and I was still getting nominal performance, and the noise would go away shortly after it connected.However, after noticing much slower data rates today than normal (less than 1/10 my typical rate), I did a reboot of the modem tonight.Now, it won't connect at all to xfinity.  It will flash a single green led then go solid amber for about 10 seconds and repeat with a lot of high pitch noise.  Verified coax and ethernet cables are good.Prior to reboot checked through xfinity that it was connected and no outages.  Verified after attempted reboot via removing power for 30 seconds to the modem that xfinity isn't seeing the modem and no outages in my area.  Have now re-attempted to reboot multiple times with the same result.I finally decided to pull out my old SB6190, figuring I would have

How do I get phone support for a replacement modem?

My S33v2 Modem is dead, I have gone through all the troubleshooting steps and the cable company came out and confirmed that it was not work.Please send me a new one.

I replaced a Netgear cable modem, I have a S33v2 and using the 2.5 GE eathernet port it is connected to an Azus GT-AX11000.  However the ethernet port is blinking yellow, my connected devices via the Asus can get 700+ Mbps, so it seems like it working fine.  But per the manual I would have expect the ethernet port to blink green indicating a 1 GE connection.   A bit confused. thanks in advnace David
