Hi everyone, I’m currently working with an Arris SB8200 cable modem and need some technical guidance. I'm trying to automate a WAN reset routine for my home network, but I’m hitting a wall with the device’s firmware behavior. Has anyone here worked with these modems to enable remote reboot capabilities or bypass the authentication requirements? Any advice on scripting this or alternative hardware solutions would be greatly appreciated.

I solved this issue after continued research on the internet but after hours and hours of resetting and restoring the brand new modem as advised by the surfboard chat techs. I am not good at computers at all but do know enough to follow instructions if the correct ones are given. I kept saying to the techs I felt it was just something on the modem not clicked on (or off!) but that dialogue was ignored. Too long of a story so to cut to the chase for someone else who might have this issue with their new Arris modem:Setup new modem and connected with my internet provider and everything worked and streamed just fine except calling over WiFi. Our house has a lot of trees in a rural area so we do not have cell phone service without WiFi. I knew it was the modem that was not allowing the calling over WiFi as I went to a neighbor’s home, was on their WiFi, and could make a call no problem. Thus, not my phone or my internet provider’s issue. Tech support ignored me when I told them th

SB8200 failing but website says serial number not foundMy SB8200 purchased in November 2021 keep dropping the connection since Xfinity upgraded things in the neighborhood. The connection keeps dropping. Xfinity says there is no outage. I've already upgraded the coax and splitters, etc. Still keeps dropping. It was running PERFECTLY FINE without a problem until they updated the neighborhood (Up to 10G). I cannot contact customer support due to the website saying my serial number cannot be found. I have tried entering it multiple times in different formats with no luck. To fix it, I just disconnect and reconnect the coax, and power cord, Then I am running fine for a day or so. Thank you! 

I am trying to connect to my 5g network. Keeps saying my username is incorrect on 10.0.0.1 login page. I checked the log in information, so not sure where to go from here. My regular non 5g network is showing on the right hand side, I just want to add the 5g. Thanks 

Trying to access my S34 modem on my LAN using Chrome, and the site displays the “Not secure” message. I downloaded the certificate, and imported it into my Chrome certificate manager, yet I am still getting this error while accessing the S34. Is that certificate valid?

Connected new G20 modem/router and everything connects (TV for streaming, phone for internet use) but mobile calling over WiFi is not working. We have no phone service inside our house without WiFi calling. Mobile calling over WiFi works at neighbor’s house just fine.

SB8200 will not power-up, no lights as of yesterday. Purchased Nov 2023. Power adapter had gone bad about 6 months ago. Power adapter reads that it’s giving out voltage, but once more, the modem is not doing anything.  

We stream all of our tv services and our wifi is slow and intermittent. I was told that I should increase my gigahertz and or update my firmware. Can you please assist?

I’ve had two Ethernet ports activated on my SB8200 for a number of years. My ISP (Astound) says I’m still provisioned for two IP addresses. As of last evening (12/21/25), I only get Internet access through one address. Power cycling the modem sometimes results in it activating the other Ethernet cable connection. The lights on the cable modem flash showing “traffic” on both connections but only one at a time has an actual internet connection. I’ve bypassed the issue for now but need advice if this is possibly a modem issue or if I need to go back to the ISP again (15+ wait time on phone for support)?

I try to changed my password but when try to login, i received the name or the password are invalid. i reset the router and i try with admin/password admin/admin and only admin

I have had the same issue. It worked well for a few days no issues and now we have to keep powering down modem and restarting it for the connection to come back. There are no issues with my internet provider and have never had to restart modem at least twice a day.

Dear Arris,Many manufacturers of cable modems provide software control to reboot modems within their devices’ GUI.This has always been a helpful option, but gaining significantly more importance with the increased adoption of home automation systems.  It is becoming critical for users to establish automation routines to resurrect WAN connections to the internet after an ISP network, or electrical outage.Your SB8200 has the ability to reboot on command.I know this because:ISP help desks (e.g. Spectrum and others) can reboot the SB8200, and some even allow users to reboot their modems from their user mobile app You (or my ISP) altered the firmware, hiding the code in the modem’s GUI configuration page by commenting out the “reboot” button - AND - the onboard script checks for a user’s ID# if the form is submitted without using the form on the configuration page.Here’s the code you commented out, so it no longer dis

ordered last saturday, with faster shipping. my card was charged. i did not receive a confirmation or any tracking information. there is no way to contact anyone about this on the store website (really, just a ‘do not reply’ email ?!?)please respond: https://community.surfboard.com/members/surfboard-moderator-593 as you have to others with the same problem….what is going on ?

We have been using the S33 for our customers and they have worked well. We received S33v3 on our latest order but they will not switch from the default 42mhz upstream limit to the mid-split 85mhz limit. Do we need a new config file and if so, how do we get it?

How do I reset  my password for an SB6183    

I assumed when I bought this that I could run two ethernet cables from it at the same time because it has two ethernet ports. Just found out that is not possible. One can only run one at a time. Without having to physically switch cables, is there such a thing as a modem switch to multiple devices (i.e. desktop, router, personal server, etc.) without having to move cables?

I have a new s33v3 modem. It’s solid blue and the cable company assures me the connectivity is good. It’s been registered to my account.  i have a google router that also is working fine when connected to the cable company’s modem.  however when i swap Ethernet cords from old modem to new modem, the router doesn’t work and doesn’t recognize the new modem.  I’ve of course reset all 1000 times.  please help. 

ever since switching from my xfinity router to this arris modem whenever im on a teams. google or zoom video call people can barely hear me its very frustrating 

I just purchased the S34 modem and never got an email confirmation.  I have a login and got some marketing email but am unable to initiate a chat, call or any means of contacting Arris. This doesn’t give me a warm fuzzy feeling.
