Modems

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?

how to log in s33v2

Hi,  The modem is solid blue and says it’s online but I can’t find the WIFI name when looking for WIFI. I called Xfinity and on their end there is nothing wrong with the WIFI connection. So I’m definitely under the impression it’s the modem and some connection with that. I don’t get why my WIFI is not discoverable . I thought it was under Xfinity Mobile WiFi but I can’t login there either.  

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 

I started getting issues since past one month, Xfinity asked to change modem.  

I can’t get my surfboard to power up

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? 

Howdy folks, I have an SB 8200 that has been working great for 4 years, but over the past 6 months or so it has been dropping connection semi-regularly. After Googling that the unit should last 2 - 4 years I figured mine must be at the end of its lifecycle. If that is true, what should I replace it with? It still seems to be rated highly. I'm not very IT sophisticated although my whole house is smart tech equipped. I use Cox Coaxial gig speed for my internet. Any suggestions for replacement make and model would be appreciated. Thx

At the request of my ISP WOW I am attempting to connect a new Arris SB8200.After connecting the power to the modem I received a single green power light on the front of unit.I pushed and held the tiny reset button in the back for 15 seconds although I didn’t feel any spring to it?I connected the ethernet cable from my Windows 10 PC.Opened my browser with the 192.168.100.1 address to test the ethernet connection and it would not connect? rebooted PC still no connect to 192.168.100.1.This PC connection is known good I am using it successfully to post this with my old Arris SB6141.   Its the simplest ethernet to PC single connection no router or any other devices.No flashing lights on the front of the SB8200 modem after the reset either?I have not moved the coax cable over to the new SB8200 yet since I can’t login using Admin to check the signal strengths.Very impressed with my old Arris 6141 and the WOW customer service said your forum

Hi. Surprising how those little (especially the blue ones) LED’s light up my spare bedroom at night. I’m guessing there’s no way to dim them on the unit itself?  There’s no user manual and I’m unable to access the device with that IP address shown in the quick start guide.  Sux but looks like I’ll have to block the lights with something.

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?

I need to activate my modem 

I came home only the 1st w lights were lite up I've unplugged both modem and router box and after that it blinks yellow and goes back like it was no internet connection at all

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

I just purchased a SURFboard 8200 v3. The Receive and Send lights both show as green, indicating DOCSIS 3.0 is being received. My ISP is Spectrum, and their local office stated that they have only been using DOCSIS 3.1 in my state for several years. I have seen some other answers regarding this issue related to “provisioning”, and that the issue lies with the ISP, not the equipment. I’m unsure of the proper question to ask the ISP. What is provisioning and what do I need to ask the ISP to do to try and address this issue?

How do I activate MOCA on my Arris SVG2482AC modem ? On the back it does signifies MOCA

First post, hope I’m putting this in the right place.TLDR: Xfinity activation bricked a previously activated SB8200, and their tech support told me to contact Arris for a "configuration file".****I've used a self-owned SB8200 with my Xfinity plan for 3 years, but after upgrading to the gigabit plan, Xfinity began sending me email notices that my equipment isn't capable of fully utilizing my plan.So, I bought a recommended Arris S33, swapped out the SB8200, and had the S33  activated and running in minutes. I put the SB8200 back in a box for storage, feeling it would be handy to keep around if the S33 failed in the future.Although the S33 performs just as well, if not better, it is much hotter than the SB8200. So much so, that I decided to return it to Amazon and reinstall the SB8200. (I don't like hot electronics, but that's just me....)BIG MISTAKE.....Upon swapping the S33 out for the old SB8200, I found that Xfinity's system wasn't

Was advised by WOW I needed a new DOCSIS 3.1 modem so I bought an Arris SB8200 used from Ebay.Attempted to provision with WOW and tech said system was receiving a “walled garden” error?First thing I did was push the reset button in the back of the SB8200 waiting about 20 seconds until the two blue lights and one red light briefly lit before blinking out.When I released the reset pin after the reset the power light came on but the blue and red network LED’s did not blink?Modem should have been reset at this point so I attempted to verify by hooking up a single Ethernet cable to the top ethernet port of the SB8200 leaving my working ethernet connection on the PC. (no other routers or devices to cause issues)typing 192.168.100.1 in two different browsers and modem failed to connect?Normally you could at least reach the gateway of an SB8200 and enter Admin userid with the last 8 digits of the serial number.  This way you can view the signal stre

Hi. I’ve spoken with Optimum, and the SB6190 is supported by their service.  Before I get started disconnecting the TM822 and connecting the new SB6190, would be great to get some input from experienced people here.  I have a Linksys EA7400 wireless router connected and working presently, I’m hoping that it won’t be an issue to connect to the new SB6190.Possibly any videos which might help if/when running into any issues?Thanks very much.

Have had my SB8200 connected to xFinity cable service for over a year with no issues.  2 days ago we experienced a 4 hour xFinity outage, after which my PC is the only device that the modem will connect to the internet with. My mesh WiFi system won’t connect to the internet, nor any other ethernet devices such as my Apple TV.  I have rebooted the modem several times and eventually did a factory reset and registered it again with xFinity.  Speedtest on my PC gives me 590 mps download, paying for 500.  The problem persists. Does anyone have an idea of why my PC is the only device it will connect to the internet with?  Any suggestions on correcting this issue?  Much appreciated.rvhughes1
