Modem is hot to touch on S34

I have a new S34 modem that I received from Amazon. I activated it on August 29th and have been using it since then. I had a disconnection just a little while ago (it did come back online right away after a manual restart) and I noticed that the exhaust from the top of the modem feels hot. I measured it with an IR thermometer and it is reading between 120F and 130F (49C to 54C). My room is 75F (24C).Are these temperatures normal for the S34?

S33 Modem Not Acquiring Downstream Channel on Sparklight

Greetings,In the past few days my S33 modem, which until now has performed perfectly well, has suddenly stopped connecting to Sparklight’s cable network. After investigating the interface, I learned that it was stuck at “acquiring downstream channel,” and after calling Sparklight learned that it had suddenly dropped off their network and as far as they could tell everything on their end was working fine. I’ve attempted several restarts and two factory resets, which have done nothing, and am not sure what to do next. I wanted to call or chat with Arris technical support, since this modem is in warranty until December 28th 2025, but the live chat option on their support webpage only says that it’s working without any interface for actually connecting to chat (in Firefox, Safari, or Chrome), and the call section doesn’t actually list any phone numbers to call. So I can’t do that, either. Does anyone have any suggestions for further troubleshooting activity or other suggestions for next st

Where to get Arris S33 Root CA ?

When trying to log into the modem using 192.168.100.1 the page never loads. I used to get a warning that it wasn’t safe because the modem uses a self-signed certificate. I can’t even get to that page anymore.Is there a place where I can find the certificate so I can add it to my keychain and trust it?The name of the certificate is “HWROB Device Root CA” “HWROB Device Sub-CA 24”  “0000B4D2471B”The error is "0000B4D2471B" certificate is not standards compliant”

s33 eventually slows to 86mbps when i have 1.2 gig Xfinity service

Like many others on this forum I’m stuck between two service providers who keep pointing the finger at each other (Arris and Xfinity). There is a design flaw somewhere and neither party is willing to address it. I’m tired of being in the middle.

S33 V2 with xfinity. Is update 1.3.2 Build 20240325 rel.56896 safe to do?

Hi All,  Just upgraded my modem/router combination to separate devices.  Using Arris S33V2 and have stumbled my way through the setup.  I think It is working OK, but I am being offered an update.  Should I do it?  The current firmware version is 1.2.3 Build 20230603 rel.46473(5553) and the offered update is 1.3.2 Build 20240325 rel.56896  My present xfinity service is 500mbs and I have no intention to upgrade my xfinity service.  Thanks for your help,

I lost my software license paper for my s33 modem. How do I get it back?

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?

SSL/TLS Errors after installing new Surfboard S33v2

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

Arris S33 modem dropping DOCSYS 3.1 connecton wo XFINITY GB service

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 S33 not working

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.    I never plugged the second one into coax so I don’t think it could

s33 Power Supply Faulty

Have you had to replace your power supply (12V 1.5A 5.5mm with 2.5mm + (pos) middle with -(neg) outside plug) for your S33 Modem?  Thumbs up is a yes.I bought an S33 Surfboard modem on 4/8/2023. On 8/3/2024 it stopped working. Reviewing the community blog it became apparent that the power supply was the likely cause. I replaced the power supply at my own expense and the S33 started working again.

Intermittent internet connection and LED light is blinking

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.
