SB8200

I just purchased the Arris Surfboard SB8200 modem.  Comcast has already registered and configured on their end.  I have two ports on the modem, I have one port direct connected to my wife’s work computer that has an IP address.  The other port is to my router for WiFi which is not getting an IP address for it.  I was informed to call ARRIS to configure the new modem. I’m waiting on hold for a support rep now.  Figure I can get some answers/help from the community.

My SB8200 does get Internet and is working but my Google nest router doesn't seem to get anything from it so I can't learn in my nest router 

If I install new sb8200 cable modem, who changes the login password to modem when done?does the cable company do that or do i changed it from default? 

I was trying to save $15 rental fee and was given used Arris SB8200 surfboard. VYVE activated it on their end but they said arris had to give me the information to get it working? There is no # to call. All I can do is write on this forum. Can someone help?

Is it possible to turn off the lights on the modem at night?

I bought a new Arris Surfboard SB8200 on Amazon, but the seller is listed as “Unlmtd LLC”. Am I eligible for the factory warranty?

Does the sb8200 support a vpn

today ive noticed all my light on the modem were green. took me asking on facebook to find out that mean i am using docsis3.0 not 3.1. ive tried everything i could think of as a troubleshoot. finally i logged in to the interface and saw that there was a failed update in the logs. I think that might be causing the issue. i get it as a modem you cant manually update it as you could a router. is there anyway to fix it or do i really have to buy a new one?

Sb8200 incoming light weak and not Blue. Outgoing solid blue. Internet gets dropped for brief periods. Are these issues related? Does modem need to be replaced ?

How do I log on to my account to upgrade security on my Surfboard 8200 modem?

What do I need with a 3.1 surfboard to connect to a TV?

I bought this modem yesterday and all lights were on.  Today, I only have the 2nd blue light on (which tells me that I’m receiving ok) but NO other lights are on.  I’ve rebooted, but it stays the same.I have a nest router attached that works fine. I also attach a switch from the nest, with a cable to my TV - which also works fine and has wired internet access.where did my lights go??? Thanks / Dan

I have RCN internet and a few times a day my internet is dropping out for about a minute or two.  When it’s working everything is fine (no speed issues or anything).  It’s the random drops that are the problem.At a glance it looks like my upstream power levels are low and I’m getting some errors in the system log that I don’t fully understand (Commanded Power in Excess of 6 dB Below….). RCN’s merlin page also shows micro reflections as red and yellow with values of -17.101 DB (red), -19.522 DB (yellow), -17.845 DB (red).    

I need the input/output voltage, output current, polarity and plug size or a part number of anyone can assist me with finding an AC adapter for SB8200 Arris modem. I went to hook mine up a yr later and cannot find it.

I unplugged the modem & router & internet cable and moved it all to a different location in the house.But the internet plug in the wall must not be hooked up, so I moved it all back to where it all wasbefore.   Does the modem need to be reset ?

For seemingly no reason my SB8200’s DS light started flashing. There are no reported outages in my area, no cables have been moved, shifted or otherwise touched. I spoke with my ISP and they advised that my modem was not able to be detected. Any suggestions ?

The hard reset username and password - Admin and password - isn’t working. I’ve tried uppercase, lowercase, etc. I’ve also tried one and the other blank. How can I log in? 

My laptop is directly connected to an SB8200 that is up and running on my ISP(Cox).  I can access the modem via cell phone app, but I cannot access via PC.  When I browse to 192.168.100.1, there is no response.  I can browse the internet, so the modem is active and working. The phone app does not provide access to settings (bridge mode).  The IPCONFIG (commandline) lists a gateway IP that does not respond.  I’ve tried a lot of other typical modem IPs - nothing enables access to sign into the modem. We have tried numerous ways to sign in, so please do not suggest the methods described in the manual - BEEN THERE - DONE THAT - IT DOESN’T WORK.  

I’ve been using very very slow internet for quite some time now , I use xfinity service but purchased your device . Look I know xfinity updates their modems automatically but I’ve never updated your device since purchase . Anyways, I’m suspecting that something is wrong a not only one . I noticed my router is open ? So it says on site . And upnp is the settings it’s currently on. Now I can’t connect at all and I’m gettin an error message saying  he following : Internet Connection not availableInternet connection is currently NOT available on your mobile device.ARRISERROR CODE: 0002-1002TROUBLESHOOT before contacting support I’ve tried my best to find ways to figure things out in my own but I keep reaching a dead end and login in also fail cuz it says it locked due to fail attempt when I’ve barely have ever tried too do soi looked up the s/n [edit: removed personal information]and it points me to this device in fact being

I have contacted my Internet provider who directed me to you for help. They said I am having issues with the modem locking onto the router?

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.

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]

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?
