Arris Modem #SB8200 I own it. Firmware update available?

I own the Arris Modem #SB8200 and I needed to register it with my internet provide when I installed it.  I controller this modem completely, is that correct?  I am wondering if I need to install firmware updates or this is done automatically when I own the modem.  I see that when the ISP owns this modem, they are in control of the updates.Thank you.

Using Moca Adapters with an ARRIS (SB8200) - Cable Modem - Fast DOCSIS 3.1

Hey there, Community, I own the ARRIS (SB8200) - Cable Modem - Fast DOCSIS 3.1 , Approved for Comcast Xfinity, Cox, Charter Spectrum, & more | 1 Gbps Max Internet Speed, 4 OFDM Channels I bought the ( 2x pack ) of  ARRIS SURFboard mAX W121 Tri-Band Mesh Wi-Fi 6 System, AX6600 Speeds up to 6.6 Gbps, Coverage up to 5,500 sq ft  The speeds for wifi have been MUCH better than they were before. We have 3 gamers trying to vy for the wifi so I'd like to drop that to 2 by adding a Moc adapter to my room so I wouldn't need the wifi while gaming. I got a ( 2x ) starter kit of the ScreenBeam Bonded MoCA 2.5 Network Adapter for Highest Speed Internet, Ethernet Over Coax - Starter Kit (Model: ECB7250K02) hoping to be able to plug my PC in that way and take advantage of the ethernet speeds but on the other side of the house from where the router is. However when I connect everything as instructed I can't connect via ethernet due to an IP issue? I think? Is this something I can resolve on my own

No internet on SB8200

New SB8200 is not receiving internet. Cable provider says they have done what is required on their end. I have restarted and hard booted. The internet light blinks for a bit then stops. What is my next option?

Lightning damage? SB8200

After a lightning storm, my SB8200 modem is showing flashing icon (scanning for downstream channel Internet connection). Does this indicate that the modem is damaged or that the Internet service is damaged or interrupted?  Mediacom says problem is with the modem?

SB8200 in warranty. All lights stuck on. no internet

My internet stopped working and when I went to reset my modem I noticed something odd, the lights aren’t going off.   Now of course when I unplug it they go off but when I plug it back in they immediately turn fully back on. i tried resetting it with what I think is the reset button on the back (there is a hole but it’s not labeled) and also tried the IP for internet reset but it’s not coming up.

SB8200 needs an rma due to intermittent internet connection

Hi,  i have a surfboard SB8200 modem. Just today, it started to behave funny, would drop internet connections frequently. I checked with Comcast, everything is fine in my area. Upon rebooting modem (unplug the power cord), I would get Internet for 10 mins before it goes out again.  logging into the arris status page, I see Upstream bonded channels sometimes doesn’t existing and there’s only one downstream bonded channel too, which doesn’t seem right at all considering I have 300mbps service with Comcast.  I already checked the warranty status and luckily I’m in warranty. The SN is 21T5J1699603171. Can you progress an RMA replacement for me asap as Internet is down for my whole house.

Slow speed internet on Sb8200

I have had my internet and Arris installed for a grand total of 7 days and I am infuriated. The router reboots randomly. Had Xfinity out, they say Arris is not great and it's not their signals. When it comes back up, it is so slow. I ran a speed test, it didn't complete the test. I see a red error message from Ookla. "UPLOAD TEST ERROR" A socket error  occurred during the upload test. A firewall could be blocking the connection or the server might be having issues." I am not a network tech and have no idea where/how to start finding network logs, etc.

Refurbished SB8200 from Amazon is dropping connection 30+ times a day

Zito Media (my ISP) sent out a tech because how how frequently the internet has been dropping out. But even after running a new line into the house the problem prevails. They told me it’s a problem with the modem. I have only had this modem for 9 months but it was refurbished and now just barely out of warranty of course. Is there any fix or can I get any sort of credit/discount on a replacement modem?

Slow speed internet on SB8200

I have an SB8200 and pay for 1 Gig download from Xfinity.. I get a lot less than that and when I speak with Xfinity they just say its a modem issue with the SB8200. Everything looks fine with the modem. Downstream Bonded Channels are all within range - the Upstream Bonded Channels are a little low but not huge. How do I run a diagnostic test on the SB8200. This is the second SB82000 in 4 years and I don’t want to buy a third if they don’t last much beyond the warranty. Having said that, I don’t trust Xfinity

SB8200 Stopped working.

SB8200. Modem stopped working, wont connect. have tested all cables. They’re fine. have hard reset modem multiple times and have attempted to login to Arris using IP, but all default usernames / PW’s do not work. I’ve wiped history and cache and used multiple alternative browsers. I’ve tried admin & last 8 of S/N. admin & pw. cusadmin & pw. I’ve tried all variations with blank pw so just clicking enter etc. Nothing works! Unable to login to see modem and try to resolve issue. Also this “live chat” isn’t a LIVE CHAT at all. Terrible “customer service..”

sb8200 Losing Power and ethernet port light is on

So about once a day now out SB8200 modem loses all lights on the front, not even the power light is on.  We unplug and plug it back into the wall outlet and it refreshes, but sometimes only for a few hours, sometimes for a day.We did do a full reset 2 days ago to see if that would fix the issues, but it is still losing all 4 lights in the front. Though the network cable lights in the back are still on.Any thoughts on what is going on with this unit?

SB8200 not providing internet

I bought the SB8200 around March or so and have connected it without it actually providing the internet so I had to borrow a modem in the mean time. I have contacted and had the ISP who have come out multiple times without coming to any conclusion other than that modem is the problem. Is there any reason for this? Is there an easy and clear way to troubleshoot other than just restarting?

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 Cable Connection physically too small to fit my cable.

SB8200v2 cable connector/nipple is smaller than the old Arris Modem it replaced. therefore, my cable is too large and will not screw on the new 8200. is there an adapter for the cable? is this a new standard? do I have a foreign version of the SB8200? please help.

SB8200 (COX) drops internet briefly

Hello - I have an SB8200 running on Cox. We keep getting booted from the internet for short periods of time (10-30 seconds) at random times of the day. Cox has tested everything on their end and says there is no issue they can see. This is a privately owned modem, so they are unwilling to troubleshoot any further.  I pulled the SNR data and have attached the Downstream Bonded and Upstream Bonded readouts: The upstream numbers don’t seem to fall in the range specified in the “Cable Signal Levels” document https://arris.my.salesforce-sites.com/consumers/articles/General_FAQs/SB8200-Cable-Signal-Levels Is there anything else I can do to troubleshoot on my end, or anything I can take to Cox to get them to come out?  Thanks so much!
