Modems

I am just trying to register my Arris S34 and it keeps telling me the serial# is incorrect.

I moved out and used my old router but I do not have to password. If you could send me the password that would be great(Edited private message)

After a recent Xfinity outage I am unable to connect to the internet using my desktop which has an ethernet cable plugged in the back of the modem. I can connect wirelessly on my laptop. I have tried two different desktops, three ethernet cables and all four sockets in the back of the modem. The error message on the computer is that the device does not have a valid IP configuration. I have reset the IPv6 and IPv4 addresses automatically, and also typed them in manually but the computers still cannot identify the modem. Thank you

Need to factory reset my surfboard S33. Depressing reset button does nothing.  

Hello all, does the V3 after the product name ,for example S33v3 mean its the 3rd revision of the product, or does it mean its the 3rd firmware version of the product?

Hi,I have the following Arris Setup:Modem : S33Wifi Router : W121 Kit - Two W21 - SURFboard mAX Mesh Wi-Fi 6 system - AX6600 Speeds.My Xfinity Plan is 1200 Mbps download and 35 Upload.Everytime i run speedtest, i dont get more than 400 MBPS download & 30 MBPS upload.If i reach out to Xfinity, they are promoting the Xfinity Gateway for monthly rent.Any suggestions how to speed up using existing Arris S33 + W121 Kit Setup ?

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’m having a hard time getting my router to connect back to my TV. It says that it has a strong signal but is disconnected from the Internet. Not really sure how to get that fixed. I have connected my hotspot to my TV and that works, but even hard wiring Into the modem is not working 

Hello,I need to cancel an order I placed.Also, it is ridiculous that I have to make a forum post to get support. The support site only allows you to use the contact methods if you have the serial number. I obviously don’t have the serial number because I don’t have the product and don’t want to receive the product. There should be a support number on my order page to get support for the order I placed.

Sharing the results of 4 Astound “technician” visits w/r/t loss of 75% download speed , a broken Hitron modem, and a working useless Hitron replacement. Note that the Crackerjack Box Hitron modems rented from Astound come with a fixed subnet in their “default” ipAddress which is the equivalent to getting a ‘locked’ cell phone. It locks you into that subnet if you add the modem first, but ruins your LAN speeds and address-sifting if you add the modem to an already-existing LAN which uses a different subnet. Of course, deploying no ‘forward’-compatibility, the firmware web page does not allow the customer/admin to modify that ipAddress. That and any other “admin” functionality” does not even exist on their page. It’s called ‘authoritarian’, ant-user, and chiefly, “lame”. Naturally, with so many “default” user/pwd pairs floating around, none worked, esp. because there was no connection made.That presents issues for those avoiding the security and slow-down associated with ALL Wo

Is there tech support you can talk to on the phone

Hey all.  So my new SB6190 is activated and working (Optimum is my provider).  I’ve tried what has been suggested in this forum in order to log in with 192.168.100.1, yet haven’t been able to.Question...does it matter?  Is it important to get access in order to change UN and PW?  Is there a security issue if not?Not too happy with Arris that logging in is an issue.  I was going to download the mobile app but I don’t download apps that require access to what’s on my phone.Thanks.

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
