Modems

Can’t find the latest firmware version for my SurfBoard SB8200, which is in boot loop. Arris official support website for this product is empty, no links.

Hello,  I was using the Xfinity-provided combo unit and decided to purchase a better standalone unit.  I went with the Arris Surfboard S33 modem and a mesh network router system.  My Xfinity plan gets up to 1.2 GB of download. Since installing the S33 modem about a week ago, I'm only seeing downloads around 100mbps.  Any video calls have been very choppy as well.  I have an Ethernet cable connected from my router to the 2.5GE port on my S33.  The light on said port is blinking amber.  From what I'm seeing online, that means it's on a 100mbps connection. How can I improve this connection to get closer to my plan maximum?  I've reset the modem and nothing's changed.  Any help would be appreciated. 

How do I remove devices from my router that I don’t want connected. 

I spent a couple of hours on the phone with Astound (formerly RCN) and they could not get my SB8200 to provision. they would send signal, lights would blink, and then it would just turn off. If I reconnected the ISP supplied modem there was no connectivity issues.Tried to call Arris and even though they say they are open 7-Midnight central time the voicemail said they were closed at 10:25PM.I connected directly into the modem and couldn’t communicate with it either as the modem won’t stay on. Any ideas?

Hi, I purchased an arris modem: https://www.amazon.com/dp/B07M8BNVSD?ref=ppx_yo2ov_dt_b_product_details&th=1I would like to check if this router is compatible with it: https://www.amazon.com/NETGEAR-AC750-Dual-Router-R6020-100NAS/dp/B01NBBA1HS/ref=sr_1_3?crid=3VD3NFEUB8IC3&keywords=router%2Bwifi&qid=1699888830&sprefix=router%2Bwifi%2B%2Caps%2C78&sr=8-3&th=1Thank you! 

I have an Arris SB8200 Modem. Recently, it is resetting (i think) or turning off and turning on multiple times a day. It is extremely frustrating, as it used to never do this and now it is constantly doing this. The blue lights will go off, and then will turn yellow for about a minute and then go back to blue and the internet is back. Attached are the event logs and other info about the modem. What do I need to do in order to make this problem go away? Thanks in advance to anyone who tries to help Downstream Upstream[EDIT: deleted image with personal information by moderator]

Got the S33 to replace my Xfinity modem. Had the internet switched to this modem. Xfinity saw the connection activated on their end, but I couldn’t see the WiFi name on my end. Tried to search for Admin and used both the serial number and “password” as the password. Neither worked. I was able to get Xfinity to activate the old router in the meantime. What should I do now? Any help is appreciated. 

Hello, I don’t believe I was given a default username and password for my modem.  What would they be by default?  If needed, how would I hard reset?

The warranty period for my Arris  SB6190 modem is until March 29, 2024. Yesterday it just stopped working. How and where can I send a faulty modem for replacement? The link to support from previous responses to comments is not active.

I can’t find password for sb6183

Unable to connect to network. Password not accepted.

The modem is only a few months old and since a week I have an issue with it.I use comcast/xfinity and the downstream connectivity light has always been blue and the upstream has been green because of the slow speed of 40mbps.My download speed has always been about the same which is 900 mbps. Since the downstream connectivity light has turned green (last week) my download speed has not changed it’s still about 900 mbps and more.The only way I can have back the blue light to come back it’s by recycling the power or resetting the modem but the blue light will not last. During the day or next day it will turn green again even though the speed is still 900 mbpsAnyone has any idea why this is happening? Thank you

If i connect my laptop straight to the modem most pages work, but when I plug my router it stops working 

S33 modem stopped providing internet service. Front panel LED is flashing green at Avery high rate for speed. Tried power off for multiple minutes. Tried resetting and reboot procedures. Same LED high flash rate (essentially a flicked). Tried direct computer network connection to access the modem default IP address, no response from the S33 unit. Any other options to get this unit working?  Was purchased 3/31/23 and is still under warranty. Not sure how to make replacement claim if the S33 is truly dead. 

The online light will not co.e on and says no internet connection we unplugged it and reset it still nothing! Frustrating 

Dead SB8200. It's been barely 6 months since I purchased this modem and it's completely dead. I have a universal adaptor to make sure it wasn't the power cord. This thing is dead to the world. Nothing I can do to fix this. It's still under warranty, but I can't seem to get in touch with anyone to find out what I need to do with a piece of junk.  

Hi, my SB8200 is about 3 years old. My ISP is supplying 500 mbps but I’m barely getting 200. Cox’s answer is that my modem is outdated and should be replaced. They will basically not do anything to help. I’m no expert and I realize things get outdated, but I don’t think that’s the case. Looking for opinions, some advice. Should I replace my modem?

Short and to the point.  I have a surfboard sb8200 and 2 mesh w21's. Only 3 days old from Amazon.  I have 4 devices way passed the satellite and there all 2.4 only and their only on the main router.  I have a camera off a ways also and it's the only one on the satellite. If I go outside with my Galaxy watch it goes on the satellite. The main says there are 4 devices with poor signals, but still work, and they won't go on the satellite. My main has 15 devices and my satellite has 1 and my watch sometimes. I've read lots of ideas from people that think their correct. It's crazy arris won't help anyone, they just have self help. I'm going to wait until 1 month when the warrenty is about to expire and return it and keep getting a new one until I get help. 👍

Dear Arris team,Appreciate your support inform me default username and password for web page login VAP3400 AP,Thanks

I just recently bought the s33 modem in hopes to lower my bill but now I’m not getting the upload speed I was getting with the xfinity modem. I talked to comcast and the tech support couldn’t figure out the reasoning behind it. I feel like it could just be the firmware on the modem not updating properly but the tech didn’t know how to update it himself 

What WiFi extender goes with sb1690

Need help getting a repair estimated for my out of warranty Surfboard SB6190 modem.  According to the documents needed I need to submit an Itemized estimate of repair identifying the item, the issue, cost of repair (parts, labor, tax). The invoice must have company letterhead and contact information.  Has anyone does this or know who I can call/contact?  Thanks
