S33 | S34

My S33 has been making an annoying high pitched sound for about a month.  The sound got significantly worse today and it stopped working. Plugged in my old sbg6580 and contacted my ISP and now I have Internet back. Arris expects me to have a cpu with an Ethernet port but not many laptops come with Ethernet ports anymore. Nether my laptop not my finances laptop have Ethernet ports. Arris says if I can't connect a computer to it there nothing they can do for me. Modem is still under warranty until Sept. 

I just purchased Arris Surfboard S33 and I need my WIFI Username & Password. It is not in the box.

I bought an ARRIS S33 2 years ago and just the other day it started making a horrible whining noise. Now it will not connect to anything. I get a red light and constant noise. I have unplugged and left it alone for hours and came back to try again and still it will not work. I wanted to contact support but the chat is down and there is no email/phone number. What can I do? My S/N states it is still within warranty. I bought an S34 for the interim while I try and get this fixed. 

The only way I have logged into the web interface was with the coax cable disconnected. This isn’t helpful because it doesn’t show any data. I connect the coax cable and try again, browser says site can’t be reached and times out. Does Spectrum not allow access or something? This is my personal modem. Why can’t I access the web manager?

I purchased a new s34 for Cox because it says they work together. When I try to set up S34 on Cox I get an error message stating they are incompatible. This is for Cox 2g  Docsis 3.1 system. 

I just activated my new surfboard modem S33 and my computer internet is working fine but my apple tvs are not even though they show connected to ethernet. Can you help with this?

One cell phone in our household has ‘privacy warning’ and cannot access the internet. Everything else is working fine including all other cellular devices in the network.   Cannot get online to see what is connected. Need to reset username and password on Arris and do not see where to send email to reset 

On August 3, 2024, I activated my new Arris S34 modem thru the Xfinity app.This morning, I called Xfinity to ask, what’s my firmware update schedule.Xfinity said, Arris is responsible for that.Where do I go from here?Thank you!

Installed s33 modem, should I not get a new internet name to set up in settings? 

I bought my S33 in July 2023. A few weeks ago (Jan 2025) my S33 began making a noticeable buzzing/squeaking sound, which seems to have gotten louder. Hard to notice with TV on (right next to it) but in a quiet room its ultra annoying. Connectivity didn't seem to be affected though. To try to fix the noise I tried briefly unplugging it and plugging it back in. That didn't help. So, I tried to unplug it and let it sit for a bit, when I plugged it back in it gave me a white status light and makes a constant rhythmic buzz squeak now, no internet connection. Left it that way for several minutes and status/connection did not change. What's going on here?

Good morning, I have a ARRIS - SURFboard S33 32 x 8 DOCSIS 3.1 Multi-Gig Cable Modem. (Purchased Oct 2021) I switched to an Xfinity modem for a while due to a sales pitch.  I tried all day yesterday to get my S33 back online.  The reps at Xfinity kept telling me that there was an outage in my area. It wasnt an outage, my S33 apparently had some files that needed to be updated in the modem.  I spent 5 hours in chat mode with Xfinity and 5 reps. Xfinity indicated that the files were updated to teh S33.  How do I know for sure?  Is there a way to test it beyond connecting and activating the unit through Xfinity again.  What other options are possible to test the speed and operation of the modem?  I prefer not to go through that again.  Thank you all

How do I know if my surfboard is corrupted. The past 3 days I have lost service at 930pm until 930 am the next morning. I went onto my surfboard S33 to see if it would tell me anything and it said firmware NA and service provider NA which I thought was weird. It also wouldn't let me refresh, it said last refresh was November something but instead just kept rerouting my refresh attempt to this thing called Fing. Any help please.

How can I get a longer timeframe of Event Logs on my S33v2? Have been having intermittent dropouts. I believe this is a cable supplier (Spectrum) problem vs. Arris. However, I would like to set up a computer on the modem via internet port to log various elements over a longer period of time. How can I do this vs. the somewhat short period of time the Arris logs events.If it turns out this is the Arris modem how can I get a warranty replacement? I do not have a backup modem so would need to continue to use this one until a warranty replacement is sent to me and then I would send to Arris.

Spec-wise they look similar. OTOH, I’ve seen people pooh-poohing the Puma chipsets in the CODA56. What's the lowdown on that?

Can’t get my device to connect to the internet 

I placed an order from the official store and the only email I got from ARRIS was an email asking me to review the S33 modem I haven’t even received. I don’t have an order number or a way to track the shipment. Is there some type of customer service I can contact to ask about the status of my order? surfboard.com/support just 404s. 

TLDR; If your S33 isn’t working to connect to the internet, the modem itself is buzzing, the light cycles between amber for a while then a quick change to white/green and then off only to restart the cycle, you may just need a new power adapter to get it to work again. I’ve looked through several posts of the same problem I was having starting today. The modem was buzzing and there was a constant cycle of the lights no matter what I tried. The amber light was on for about 7-10 seconds and then flipped to a white/green light for a second or two before turning off and then restarting the cycle of amber, white/green, and off. Things I tried to get it to work include disconnecting and reconnecting the power to the unit, confirming that my internet service provider (Xfinity) had no reported outages, removing the coaxial cable, and attempting to reset the whole modem. When I tried resetting the modem with the reset button on the bottom, nothing happened regardless of how lon

Hi,I have unfortunately terrible cellular service with AT&T at my home and am evaluating options. AT&T has given me a cell booster and I am trying to connect it, and have been instructed by AT&T that I have to open the following UDP ports of the modem to allow the booster to activate: UDP / 500 IPSec port, UDP / 4500 IPSec port, Emergency Services Protocol (ESP) 50, and UDP 123 NTP port (timing synch). Initially, AT&T said my internet provider had to enable this, but I own the modem (not Xfinity, my internet provider). I seem to be unable to talk live to an ARRIS rep to resolve this. Does anyone have advice? Thank you!  

Our S33 cable modem is less than a year old. It keeps losing Wave Cable/Astound internet connection while using an Arris NVG578HLX WiFi router. The S33 has already crapped out twice today, and it's getting worse. Now I get an intermittent “Privacy Warning: This device is blocking encrypted DNS traffic. The names of websites and servers your device access on this network may be monitored and recorded by other devices on this network."What's wrong and how do I fix it? 

We recently started a home project and needed to cut the power off from the breaker. The router/mesh system were both plugged in when we flipped the breaker to turn off the power. Once we flipped the breaker back on, the router now shows a solid white light. There’s nothing in the owners manual depicting what a white light means. If it’s useful information, we use a deco mesh system (AX3000) that is currently showing red, which indicates it cannot connect to the WiFi. How do I get my WiFi working again?? I’ve tried: resetting the router (unplugging, pressing little reset button on the bottom), resetting the mesh system, replacing the power cord, and nothing works. 

I just got setup with Xfinity tech support replaced out SB6190 for S34.  Everything works on the modem to PC but when adding to my router it will not connect.  Thoughts?  I have a Firewalla Gold and I have deleted the network and rebooted all setup with DHCP.  Trying to avoid factory reset too many rules created on my network. thanksjoe 

Wondering, can Arris support configure their (MINE) modem for say Comcast, to work on their network?

Hello, after many hours working with comcast and missed sleep trying to provision my new S33 modem, I had a thought to log into it but couldn't. So I factory reset the S33 & was then able to connect. Looked at log & see a critical error TVL-11. Basically, saying the MAC id doesn't match the model in comcasts system saying its something other than the S33. So, when they send signal to provision it, it fails. How can mac id & model be different. Tried calling modem support but they are not open yet. Has anyone seen this before? Is there a fix besides returning it & posting a very negative review?

I have a Sony Bravia  Google Play TV. My service provider is Comcast and I connect to Xfinity TV program on a HDI port and  Google Play is configured for the port called Channel . I began having service interruption issues on my Sony Bravia Google Play about 1 month now. The Google Play App would just hang and not load at all while in the same instance the NetFlix app would load wihout issues indicating that this is NOT a network issue on my network. The Netflix APP  has  its own icon and loaded without issues and have no issues with Xfinity programming loading  That tells me that my TV is working ok, no issues with the sound or picture.  Ive began getting messages from SurfBoard and Fing suggesting that services have been handed off.  The XFINITY Remote controls the volume when ocassionally  my Sony Bravia Google Play TV  works which suggests there may be some crossfunctioning.
