Arris SB8200 power on failure

Purchased April 2023 so 16/17 months old and total failure while not home….it was plugged into a surge protector and no other devices in the home were damaged so I don’t think it was from a  power surge…..no lights on the arris  and have done all the smart things that arris would say….is the power cable inserted? Yes…did you try it from another outlet? YesWill arris cover this under warranty or is it just that this was a bit of a lemon and most arris’s would last much longer?l did swap out an old Motorola modem that still works so wasn’t dead in the water (after  coordinating with ISP)I do want to have another spare on hand wondering if I should avoid arris or not

4.5-year-old SB 8200 - intermittent issue and suggestion to buy new product.

Howdy folks, I have an SB 8200 that has been working great for 4 years, but over the past 6 months or so it has been dropping connection semi-regularly. After Googling that the unit should last 2 - 4 years I figured mine must be at the end of its lifecycle. If that is true, what should I replace it with? It still seems to be rated highly. I'm not very IT sophisticated although my whole house is smart tech equipped. I use Cox Coaxial gig speed for my internet. Any suggestions for replacement make and model would be appreciated. Thx

SB8200v3 Only Connects to PC after xFinity outage

Have had my SB8200 connected to xFinity cable service for over a year with no issues.  2 days ago we experienced a 4 hour xFinity outage, after which my PC is the only device that the modem will connect to the internet with. My mesh WiFi system won’t connect to the internet, nor any other ethernet devices such as my Apple TV.  I have rebooted the modem several times and eventually did a factory reset and registered it again with xFinity.  Speedtest on my PC gives me 590 mps download, paying for 500.  The problem persists. Does anyone have an idea of why my PC is the only device it will connect to the internet with?  Any suggestions on correcting this issue?  Much appreciated.rvhughes1

DOCSIS 3.0 green light vs DOCSIS 3.1 signal on SB8200

I just purchased a SURFboard 8200 v3. The Receive and Send lights both show as green, indicating DOCSIS 3.0 is being received. My ISP is Spectrum, and their local office stated that they have only been using DOCSIS 3.1 in my state for several years. I have seen some other answers regarding this issue related to “provisioning”, and that the issue lies with the ISP, not the equipment. I’m unsure of the proper question to ask the ISP. What is provisioning and what do I need to ask the ISP to do to try and address this issue?

Unable to access the GUI web portal on SB8200

Can any of you having problems accessing the 8200 even access its built in mini-webserver?There is no combination of IP addresses and methods suggested that will work. All I ever get is are “not responding” and “time out” messages from the browser. (The same browser that accesses the router with no issues.)This Modem is new and works perfectly but I need to see my bonding parameters because the cable company is having challenges in my area and needs feedback from my end. Their tech support said that Arris Modems are famous for being inaccessible for unknown reasons. Has anyone had success with a method not already suggested above? Thanks.

Second port is not working on SB8200v3

I have my new SB8200v3 modem and I noticed there are two ports only. The top port is no problem, but does the bottom port even work? And if it does, how do you get it to work and what can it do?

SB8200 docsis 3.1

i have had 2 SB8200’s and neither one would ever show docsis 3.1 and with several phone calls and house visits from techs they said nothing was wrong on their end but as soon as they hooked up “their Modem” it instantly showed docsis 3.1 with the blue lights… could i really have 2 bad 8200’s or is that their way of getting me to rent their equipment?

slow speeds

I have a SB8200 with a net gear router. I am experiencing very slow speeds with my Xfinity account. I have a 500mbps account. Xfinity says there is no problem coming in to the house. I was wondering how I could tell if it was my modem on my router that is only giving me about 10 MBPS?

SB8200 power light turns off every 10 seconds

My SB8200 power light turns off every 10 seconds and when it turns off the upload link light turns on for one second. This then repeats endlessly. I've tried hiding thr factory reset button for more than 10 seconds and nothing happens.  I've called my ISP and they can't ping the modem. I've tried unplugging the coaxial, moving it to a different outlet, unplugging the ethernet and nothing seems to change it.I've had the modem for 1.5 years and it's only happened one other time but the ISP was able to fix on the call.Any thoughts here?

Recommendations for a switch for SB8200

I have Cox for Internet. Cox support told me to use a switch (not a router) to connect two computers to the modem. It seems like a simple thing to do, and I want to be sure to get a compatible switch. Any recommendations for a switch?I'm also considering having a Cox technician come to my house to do the setup in case there are things I don't know that need to be done -- currently have their Panoramic modem/router. Is that a good idea?

SB8200 configuration on slow speed

I’ve been using an SB8200 for several years. I seem to recall a setting specifying the expected speed from the ISP. Comcast recently increased their speed but it seems I’m locked to the previous value (using Speedtest). How do I reset that setting (or am I remembering incorrectly)?

Arris surfboard SB8200 warranty - experiencing intermittent internet connection

Bought Arris Surfboard cable modem SB8200 from Amazon February of 2024. Needed a higher end modem to support the speed and devices we currently run. After installation just recently December 2024, we experienced extreme lagging in our web browsing and gaming. Also, the app to Install is out of date. Only older versions of Android can install it. We hooked up our previous netgear modem again, since it wasn't giving us as much issue as this newer Arris cable modem. I would like to know what the warranty will cover since it is practically never been used and we are not satisfied with the product?

SB8200 - Docsis 3.0 to Docsis 3.1

My SB8200 will not connect to docsis 3.1. I have a spectrum gig plan. Spectrum tells me my plan is docsis 3.1but my modem is stuck in docsis 3.0. I don’t see an option how to change the setting in the management page. spectrum is no help and tells me to contact the manufacturer. Any help would be greatly appreciated Also I cannot access the management page while the modem is connected to the net. I can disconnect from the net and access the page.

SB8200 faults out once or twice a year and can't access internet while connecting router

I have a SB8200 modem and for no reason at all it drops our internet connection and I have to call for a paid service to walk me through the issue to correct it.  Have my computer connected to the modem and it says everything is working fine but the indicator lights are: power - solid green, Receive - solid blue, Send - solid green and online solid green.  I can access the internet when connected to the modem but my nighthawk router will not connect.  I have logged into the modem manager but don’t see anything out of line there either.  Any ideas on why I need to call for assistance one or twice a year to adjust my settings to allow it to work again? Wifi - Netgear Nighthawk X6S, AC4000 Tri-band, model - R8000P

New SB8200 all green lights

So, yesterday I purchased a new SB8200 and had Cox activate it. However, while it works all the lights are Green, shouldn’t two of them in the middle be Blue? I’m 80 and not that tech savvy.

SB8200 Not Allowing me to connect multiple items via ethernet

Hello, I have a small mesh wifi network comprised of two W12’s (one of which is operating as router connected to the SB8200 via ethernet) and the other which acts a node. My GF just recently got a stay at home job which she got a desktop for and it needs to be connected via ethernet.  When I went to connect the ethernet into the other port initially it wouldn't connect to the desktop. So I rebooted the system to which the ethernet worked but the router wouldn't connect. After hours of trouble shooting I found myself here.  Any recommendation as to how I can hard wire a device to my modem while still allowing my wifi to work?
