Modems

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 ?

The box has no information on wifi name and password I can’t set up without putting that information in his

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?

New install, setup modem, change MAC with IP (WOW) and can connect through the modem via Ethernet.When setting up Google WiFi an error occurs.  "The modem isn't giving your Wifi point an internet connection." I follow the instructions, unplug everything and wait and receive the same error.I have fully factory reset the router, nuked my Google home, uninstalled the app and received the same error.Contacted IP, they claim all is well on their end.Reset system to provided gateway, nuke Google home again and it works. Any ideas would be greatly appreciated.    

I wanted to inquire on the status of the certification process for the Arris S33 Modem for Xfinity’s Gigabit x2 plan which is 2000 mbps down and 200 mbps up. Currently the S33 Modem isn’t approved for Xfinity’s “next gen” speed tier aka Gigabit x2. Where does this currently stand? The modem should be able to handle these bandwidth speeds.Please reference resources below for additional details. Xfinity Recommended Devices (updated 10/25/23)https://assets.xfinity.com/assets/dotcom/projects/cix-4997_compatible-devices/2023.10.23%20Full%20List%20of%20Compatible%20Devices.pdfOfficial Xfinity Reddit Post

I just replaced my Xfinity modem with an Arris S33(v2). While I’m getting about 720Mbps down I only get 5Mbps up.  I’m paying for 1000/200 service.So far it’s taken Comcast 3 tries to get the modem provisioned and they seem to be stumped as to what’s going on.The device log (which BTW isn’t sorted by date/time) contains the following after a restart (I added line breaks for readability):17/11/2023 14:59:11 3 CMSTATUS:US_Diplexer_Mode_Change:TLV-84.1, 5-42MHz.17/11/2023 14:59:17 6 DS profile assignment change.

Greetings! Our HVAC Smart Thermostat requires a “2.4 & 5 GHz, EERO, 2-address” router. Service Electric recommends “Docsis 3.1.” The HVAC tech says it must provide the two frequencies on separate addresses. I’m not able to sort through all the models to find the right one. Any suggestions? Thank you!

Xfinity 1200Mbps /  35 Mbps Arris S33 Wired on 2.5Gbps Port - connected to a new Gaming Laptop with a 2.5Gbps port using a new Cat6 - speed test range from 500Mbps / 40Mbps to often only 300Mbps / 40Mbps. Xfinity came out and can’t figure it out. When they connect their own equipment to the coax direct their test show it’s a perfect connection and all signals and power levels are in perfect range…. Very frustrated, this is my second modem, my older one was working until it all of the sudden was no longer compatible with my plan (?) online support was also no help - I have spent hours trying to figure this out

I’m trying to set up an Arris surf  S33 V2 modem and it asks to select your internet provider. I have TDS for my provider but it not one of the providers listed.  Does this mean the S33 V2 isn’t compatible and if it isn’t what modem would work - Thanks 

My SB6190 has intermittent drops throughout the day.  I just bought/activated it 3-days ago.  My service provider is Spectrum.  I work from home and cannot have this happen so frequently.  Please help.

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).    

Can’t connect to server, error 0000-1506.There doesn’t seem to be any way to retry other than deleting and re-adding the device, which I’ve done 3 times with the same result. Suggestions?

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 cannot find the admin and password name

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 ?

I can’t find my network SB6190

Internet is still not working

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? 

I went to upgrade my modem and bought a brand new Arris Surfbord DOCSIS SB 6190 to replace my old modem only to discover when I got home that I had bought the exact one again-same exact product with same model number. I know this is a dumb question but am I to assume that because what I just bought at Walmart is new that it’s components inside WILL in fact be an upgrade since it’s a new one? I mean when you replace a modem you want the latest technology and components. 

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
