S33 | S34

Hello, I was using Xfinity XB8-T for last year and had lots of connectivity issues. Yesterday I thought of going back to S33, which I was using during 2021-22. I have had stable connectivity for past 24-36 hours but my speeds are slow. On Xfinity modem I used to get 1200 Mbps down and about 35 mbps upload whenever it was working.I have my S33 plugged into cable and then my eero router is plugged in 2.5 ghz port. My S33 gives me like 600 mbps download and about 25 mbps upload? How can I make it better to give me speeds like what Xfinity plan gives me. I am on 1300 Mbps down and 40 Mbps upload plan.Please guide me as to why I am not able to see same speed. Is S33 not compatible? Is there a new firmware I should be downloading for S33. I was not using S33 for past 2/3 years.Thanks for replying back.

My teenager's profile suddenly quit working. My thought is to delete it and then set it up once again, but I can't find a way to delete the profile. Or, is the solution to uninstall the app and start over completely?

I have been working with 3rd level support with xfinity (Comcast) and they are stumped so far. I have worked with Hostgator and  they state because I can access my account outside my network it's not them. I have tried Eero tech support and they tried a suggestion to change my IPv4 and that did not work. Here is the problem:I can no longer access my email addresses (multiple addresses through same host) using Hostgator.comAlso I cannot get to www.mywebsite.com/cpanel and also cannot log onto my websites using filezilla. As of yesterday I could and did not have any problems and did not change any settings.  When I try to use find my websit I get my IPV6 but it cannot find my IPV4. I can access all of the above via my iPhone on the cellular network when I turn off my WiFi. I cannot access the above using WiF

Since August 2024, I have S34 modem. It always ran a bit hot.Recently, I can’t log in to the web interface to check event log.I purchased a different modem from another manufacturer. No Problem in heat dissipation and logging in to the interface!What should I do with the S34?

I tried over two days to replace my working SB8200 on my home network with a new S34. My ISP is Cox. On the first day I tried many times to activate it over the phone to a Cox technician. The Cox tech said she could see the S34 activated on her end. On my end I saw a solid blue LED indicator, but I got no connection to my wired ethernet LAN or my eero PRO wi-fi router. On the second day a Cox technician came to help. He worked for over an hour trying various things, but got the same result.  Finally he replaced the S34 with a Cox Panorama modem/wi-fi router and got the system working as it was with my SB8200 router. Now, however, I am stuck paying rent for Cox’s equipment, so I am not done trying to solve my problem. So, a few questions: (Question 1) Does the S34 indeed provide a performance upgrade over the SB8200? I have Gigablast service from Cox, a sprawling LAN covering 6,000 sq ft, and an eero PRO wi-fi mesh network with 6 routers total. I am planning to upgrade the eero PRO g

I am having a recurring problem.  At random times, my S33v2 Modem will lose its connection to the internet.  No warning, and no clue why it is happening.  Power cycling the modem restores its connection, and my ISP cannot detect any problems.  I run the modem through an ASUS Wi-Fi Router, and when the connection drops, we still have network access, so I know the router isn’t the issue.I have looked through a few threads, and have accessed the Web Manager to check the signal power levels.  The downstream power levels and SNR levels are within the recommended range.The upstream power levels however, are within the acceptable range (35 - 50 dBmV) according to my ISP (Xfinity), but NOT within the range suggested by the manufacturer (45 - 51 dBmV).Picture below. I have done a hard reset of the modem, via the reset s

I am linked with my eero pro 6e router through the 2.5g port but there are no link lights. I also noticed when I boot the modem there are no lights on the 2.5g port but the 1g port has lights. Any thoughts?

I do not have an ethernet port on my laptop.  How can I set up the modem? I cannot reach the manager page. 

Any ideas?

Breezeline shows signal to my S33 but have no connectivity through eero router or through direct hardwire to the modem!

Replaced an older Surfboard with a new Surfboard and the new Arris iPhone app doesn’t facilitate syncing the two. Any suggestions or help making them work together would be greatly appreciated.  

Doesn’t seem to be an easy way to request RMA.Surfboard S33v2, already registered, amazon purchase less than 2 years ago.Spectrum internet, lost connection, multiple power offs and tried reset button.When powering on, green light immediately comes on and stays on, doesn’t blink or appear to attempt to connect to spectrum.  Multiple reboots same result.Purchased new S33 and quickly activated new modem and new modem is working fine.Request replacement on old defective S33.

Spent a lot of time on this and you have no number to call, not starting out well.  Xfinity says they do not support the s34.

I am beyond frustrated here. To preface, I have the worst ISP possible - Zito Media. I honestly feel like Zito is the culprit but they refuse to provide any useful information. I own this modem and intentionally bought it so I could drop the rental Zito modem. I want to access the web manager to alter settings as needed. However, I cannot get into my modems manager. 192.168.100.1 just gives me a “hmm...can’t reach this page” message. Ipconfig tells me my default gateway is 192.168.4.1 (which doesn’t work either of course). I tried to reset the modem and for a very brief 2 minutes I was able to get into the manager but as soon as it reconnected to my ISP the manager connection terminated and displayed the “hmm...can’t reach this page” message again. Please help!

I am about to replace my outdated SB6141 Cable Modem (Xfinity is the ISP) with a new S34 Arris cable modem.  But before I make the swap, I need to try to understand what happened yesterday….  The SB6141 lost connectivity and it spent hours booting successfully through “Power”, “Receive” and “Send” but then when it got to step 4, the “online” connection, it would flicker a lot with the blue activity light flicker a lot too…. Appeared to me it was trying to talk to my ASUS router (model # RT-BE88U) but was having no success…. It would try for a while and then do a reset and start over…. Did that maybe 100 times…. I then unplugged the router by unplugging the Ethernet cable at the back of the modem…. It then booted and came up to fully booted in no time at all…. Whoa…. Doesn’t like the router…. But it has connected to it many time over the past few months since I bought this new ASUS router…. Had an Apple router on this system before and it worked for nearly 10 years with this same, ol

I have called my internet provider. Tech has been to house. Restarted modem. Still, the internet goes on and off. Blue light. Says it’s on. But, no devices work using wifi. Modem only 1 year old. Suggestions?

I have no wi-fi, Xfinity verified service is working. After repeated reboots of Arris Surfboard, cable tv ( direct connected to Arris) sometimes works. Wi-fi does not connect. Direct connect to laptop computer does not connect to internet. Help?

Is there a way to change the IP address on an S34 Cable Modem?

I just received my S33 today. Yet, when I plugged it in there isn’t a single light that is on.

This has been ongoing for a long time now, just now doing research though. Had Xfinity re-provision twice and also reset to factory settings with no luck, they told me they see OFDMA on channel 43 but I’m not seeing it on my end at all, will post the logs of the boot up and provision. Cannot exceed 40 Mbps upload and very random download speeds as well. Any help is appreciated!Event Log 

About a year ago we  were told our cable modem, model SBG7600AC2,  was obsolete and would need to be replaced. We have two computers, some TV’s and a couple of tablets as part of our home network.   We just recently decided to swap it out with an S34. When I looked at the package, I noticed the box says  we need a WI Router for whole home networking. This leads me to believe I bought the incorrect cable. If so what version would be best to purchase? 

I just purchased an Arris S33. It did not come with a user manual. According to Xfinity, I need the WiFi name and pswd of the device. How do I get this?
