Fast to slow in a minute

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

Can a PoE Splitter fix the issue with S33 only allowing one connection

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.

S34 - Timeline for release of this modem

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.

modem makes high pitch sound on S33

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.

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

packet loss increasing, seems like to be S33v2

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!

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

Modem not providing a connection to Asus Router on S33

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.

S33 high pitch noise and won't connect

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 to make do with the lower bandw

Led light status on ethernet port - S33v2

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

S33v2 Shrill Whine

Hello, my s33v2 modem has worked fine for almost a year. Within the last month I noticed a high pitch shrill whine coming from it. Is there anything to do or a way to have it replaced to resolve this issue? I have the modem in my office where I work and it is very distracting. Thank you.

Modem Stopped working - S33

My S33 modem is connected to our google wifi and the other day it went from working to this amber or green ish color and nothing is able to even detect that it is working at all. My wife tried calling and the guy even said during the trouble shooting process that it might have just broken but has anyone else had a similar issue or problem and is there a work around?

modem S33 solid blue light but no iternet

I bought a brand new modem so I could get 2gb speeds from my internet provider as my old modem was unable to do these speeds. When I hooked it up and had it added to my account it gives me a blue light saying it’s connected. The cox representative told me it was good to go but I didn’t have internet access. I called my router company and after factoring resetting it we were unable to get on the internet. They had me trying to go straight from the modem to my desktop and it still wouldn’t connect to the internet. I had a technician  come out and he tested the line and it was good and was confused on why the modem was working but not letting us on the internet. Is it possible I got a bad router from factory? I spent 200$ on the modem so I’m hoping this is not the case but I’m not sure what else to think at this point.

Intermittent internet connection on S33

As the title says, for the last few months we’ve had our internet dropping out randomly, multiple times a day. Our ISP Xfinity finally came out and they replaced outdoor connections, and tested indoors but the S33 v2 lights didn’t register internet drop though he was holding the cable.  When tested on their modem, it showed internet loss immediately and the internet was stable. Would like someone to tell me how I can fix this as we work remote and this is unacceptable.

S33 - Modem with high pitch noise

The modem was unplugged due to loud hissing noises, it was working fine. Unplugged s33 for 15 mins to let cool down and when I went to plug it in it never booted. Orange light for 10-15 secs than flashes to white for a sec back to orange light for 10-15 secs. Never connects don't see it on Xfinity side and I'm unable to get into web portal either. This product is under warranty would like a replacement I've gone through hours of troubleshooting.
