Modems

Hi,  i have a surfboard SB8200 modem. Just today, it started to behave funny, would drop internet connections frequently. I checked with Comcast, everything is fine in my area. Upon rebooting modem (unplug the power cord), I would get Internet for 10 mins before it goes out again.  logging into the arris status page, I see Upstream bonded channels sometimes doesn’t existing and there’s only one downstream bonded channel too, which doesn’t seem right at all considering I have 300mbps service with Comcast.  I already checked the warranty status and luckily I’m in warranty. The SN is 21T5J1699603171. Can you progress an RMA replacement for me asap as Internet is down for my whole house. 

I have had my internet and Arris installed for a grand total of 7 days and I am infuriated. The router reboots randomly. Had Xfinity out, they say Arris is not great and it's not their signals. When it comes back up, it is so slow. I ran a speed test, it didn't complete the test. I see a red error message from Ookla. "UPLOAD TEST ERROR" A socket error  occurred during the upload test. A firewall could be blocking the connection or the server might be having issues." I am not a network tech and have no idea where/how to start finding network logs, etc.  

Greetings,In the past few days my S33 modem, which until now has performed perfectly well, has suddenly stopped connecting to Sparklight’s cable network. After investigating the interface, I learned that it was stuck at “acquiring downstream channel,” and after calling Sparklight learned that it had suddenly dropped off their network and as far as they could tell everything on their end was working fine. I’ve attempted several restarts and two factory resets, which have done nothing, and am not sure what to do next. I wanted to call or chat with Arris technical support, since this modem is in warranty until December 28th 2025, but the live chat option on their support webpage only says that it’s working without any interface for actually connecting to chat (in Firefox, Safari, or Chrome), and the call section doesn’t actually list any phone numbers to call. So I can’t do that, either. Does anyone have any suggestions for further troub

What does it mean if all four lights are green while rebooting but the two middle ones turn blue and power and glove button go white?  I am not getting internet but isp says signal is just fine.  Also Ethernet  port is flashing yellow on back or modem and router.  Have already tried new Ethernet and resetting router and modem

Zito Media (my ISP) sent out a tech because how how frequently the internet has been dropping out. But even after running a new line into the house the problem prevails. They told me it’s a problem with the modem. I have only had this modem for 9 months but it was refurbished and now just barely out of warranty of course. Is there any fix or can I get any sort of credit/discount on a replacement modem?

I have spoken with two customer support folks from Cox trying to activate the S34. They both have told me it is not on their compatible devices list.  I chatted with a Arris customer service agent who said that it is compatible and to use model “RARS34” but this did not help.  Buyer beware.

I have an SB8200 and pay for 1 Gig download from Xfinity.. I get a lot less than that and when I speak with Xfinity they just say its a modem issue with the SB8200. Everything looks fine with the modem. Downstream Bonded Channels are all within range - the Upstream Bonded Channels are a little low but not huge. How do I run a diagnostic test on the SB8200. This is the second SB82000 in 4 years and I don’t want to buy a third if they don’t last much beyond the warranty. Having said that, I don’t trust Xfinity 

Hello.  I have a Surfboard router and just downloaded the app and want to make sure I have an account set up and have visibility into this device on my app.   

Our Surfboard S33v2 has a solid white light with buzzing and no connections I've done the following steps:1. Power cycle2. Disconnect the RG6 coax cable3.  Have tried to connect to the GUI web portal when directly connected with a rj45 patch cable.4. Reset button and repeated previous steps  

How do you change the upstream Diplex to mid-split. According to specs it is configurable.

I have a new S34 modem that I received from Amazon. I activated it on August 29th and have been using it since then. I had a disconnection just a little while ago (it did come back online right away after a manual restart) and I noticed that the exhaust from the top of the modem feels hot. I measured it with an IR thermometer and it is reading between 120F and 130F (49C to 54C). My room is 75F (24C).Are these temperatures normal for the S34?  

I switched my internet provider from Xfinity to Astound and my Arris cable modem S33 still shows Xfinity as my service provider

I have been trying to login to reset password.  Reset modem and tried the admin and password, still get error message that they are invalid.  What do I do now?  

Can't find my password 

S33 WILL NOT STAY CONNECTED TO MY SPARKLIGHT SERVICE.  

Is there a more current model to the TG2472G ?  need a modem with one or two phone ports.with or w/o wifi. thanks!

The User ID & PW I set some years ago for my S33 Modom don't work anymore, so how can I recover and/or reset again from factory? Will this affect my registration with my cable company if I safely reset using reset button? Thanks.

I need a wifi name and password for my arris surfboard s33

Whats the difference between the S34 and S33? 

Can’t access web manager for SB2800 (bought 8-21-2024, setup & running), tried going straight from modem to laptop, tried resetting modem, tried turning off firewall, tried both Edge and Firefox, no go, gives me a timeout or can’t reach this page.

just bought an Arris Modem. I downloaded the app and it ruined my cell phone. I call the number for help. They are not open on Sunday. What company cannot provide assistance everyday. Can they not even provide AI? I will never buy their products again. $500 cell phone down the drain.

When trying to log into the modem using 192.168.100.1 the page never loads. I used to get a warning that it wasn’t safe because the modem uses a self-signed certificate. I can’t even get to that page anymore.Is there a place where I can find the certificate so I can add it to my keychain and trust it?The name of the certificate is “HWROB Device Root CA” “HWROB Device Sub-CA 24”  “0000B4D2471B”The error is "0000B4D2471B" certificate is not standards compliant”

SB8200. Modem stopped working, wont connect. have tested all cables. They’re fine. have hard reset modem multiple times and have attempted to login to Arris using IP, but all default usernames / PW’s do not work. I’ve wiped history and cache and used multiple alternative browsers. I’ve tried admin & last 8 of S/N. admin & pw. cusadmin & pw. I’ve tried all variations with blank pw so just clicking enter etc. Nothing works! Unable to login to see modem and try to resolve issue. Also this “live chat” isn’t a LIVE CHAT at all. Terrible “customer service..”

Like many others on this forum I’m stuck between two service providers who keep pointing the finger at each other (Arris and Xfinity). There is a design flaw somewhere and neither party is willing to address it. I’m tired of being in the middle.  

So about once a day now out SB8200 modem loses all lights on the front, not even the power light is on.  We unplug and plug it back into the wall outlet and it refreshes, but sometimes only for a few hours, sometimes for a day.We did do a full reset 2 days ago to see if that would fix the issues, but it is still losing all 4 lights in the front. Though the network cable lights in the back are still on.Any thoughts on what is going on with this unit?
