SB8200

This is the first time I’m using Arris products and I love them! is there anything more under the hood other than going through the app? 

had a zfinity technician rule out the splitter, coax cable, and ethernet cable a possible cause, down to being the modem itself causing the problem. what could be the reason for this failure. also i am hard wired to it (no router in between). could it be a hardware failure on the inside of the pcb board? if so which component that i may de sauder and re sauder.

can I port forward with a sb8200 router? if so how?

Just bought a brand new sb8200. Came with 2 Ethernet ports but when I try to use both only 1 works?? 

My provider Mediacom has provisioned my new SB8200 but it has only the 1 blue download light lit, shouldnt all lights be on??  Also I can not connect to my netgear gigabit switch ….. 

I am trying to connect my T-mobile cell spot and it says I need to open Ports 500, 123 & 4500. How do i do this? I have the Arris SB8200.

My provider uses Xfinity and they say that the modem has issues on their end they say it is connecting and then drops it over and over...the modem is pretty much brand new...I refuse to believe it is unable to push the small town providers 1 gig speeds I know it's not the WiFi router cuz Ethernet from modem straight to my laptop is still not connecting...anyone know what my issue may be? And yes it's been provisioned to the provider this issue just started tonight

How can i enable Bridge Mode on my SB8200 on my PC and not my phone? I do not have access to wifi at the moment and the mobile app has no way to connect to the modem My issue is that my router is not getting internet from my modem - but ive confirmed that the modem is getting internet, as I am hardwired to it and connected to my ISP, Cox

I have sb8200 with COX in Phoenix, and I have exactly same thing happening, started about 2 month ago and it would drop to 30 mbps every week or so, cox came out checked the line and said it was good.

My modem will not provide internet access to either of the two Wi-Fi routers I have tried. The lan cable works with my ps5 so I know internet is coming to the modem. I have netgear routers. I have reset all of them and turned off and turned on all of them. Any other ideas?

I need to set my password/username for the sb8200 modem. I do not have original password/username, and also did a factory reset. But do not know how to change it. Please help. Thanks.

I do not understand this modem and am looking for the user manual. Where is it? 

I have everything set up and connected but I can’t find my wifi on the wifi part on my phone to connect 

  I just recently purchased the SB8200 because the modem that i was renting through the provider would never let me get more than 350mbps download and 55 upload and that's on a good day, when im paying for 1GB service.   I live in a town that is fairly small and almost an hour from any bigger cities. When I started my plan through them they put new cable all the way out to the power line. So I know there's no problems with the line at least that has been found.     I am also renting EERO devices for an additional 16$ a month just so i can manage who is on my network and set time limits for the kiddos otherwise I would not be able to receive/modify any of my network settings right?. I feel as if my provider is lying to me that 1GB service is supported in my area.   Every tech that has came out makes up a new excuse each time and they always say that the speed looks good on there end but it could be my devices or some other excuse. The only reason th

Hello, my SB8200 is dropping intermittently for about a few minutes and then reconnects. I had this same issue last year where I had to get a replacement SB8200. Here is my event log and upstream/downstream. Any ideas about what could be causing the issue? I have sent a ticket to my ISP, but wondering if this is a reoccurring Arris issue? Downstream Bonded Channels Channel ID Lock Status Modulation Frequency Power SNR/MER Corrected Uncorrectables 17 Locked QAM256 663000000 Hz 2.7 dBmV 41.7 dB 2 0 1 Locked QAM256 567000000 Hz 3.0 dBmV

My new SB8200, but its software/firmware says it is a SB6183 DOCSIS 3.0.  What is going on!  Would I replace it?

Some minimal background for context, I work 3rd shift weekend providing customer support for an operating system vendor.  This means that I get to (try to) live through any ISP changes that xFinity/Comcast throws on their victims.  About a month ago some change was made and my SB8200 that had been working fine (with a functioning DOCSIS 3.1 indication), so to speak.  Performance went to heck and none of the troubleshooting suggestions helped (rebooted several times, factory reset, etc).  At the time the modem log had an entry about a failed firmware download and most of the channels had logged both correctable and non-correctable errors.  It should have been a hint that the normal address for the SB8200 config pages didn’t respond but 192.168.0.1 connected.Enter Comcast…  After the usual foolishness the agent finally tried to ‘look at’ the modem using their tools and that was a total failure.  From my view the modem was working but, honestly, wasn’t pe

I am trying to set up the modem app for my new modem on my computer.  Have it on mobile, but as I am slowly loosing my vision and it’s hard to see most apps on those small screens.  Why can’t I find an install for the computer?  Am I just not seeing it (no pun intended).  Are you able to help with this request?

So I was using my internet as normal when I all of a sudden lose connection, look over at my modem and it is power cycling, first power lights comes on, all lights under light up and then they all turn off and it repeats. I don’t have any extra power cables for this so I tried the one from my Phillips hue bridge and same thing. I’ve tried to unplug the modem from the wall, tried a new outlet, kept it unplugged for some time and replugged back in, I’ve also tried the reset button on the back which is when the original power cable stopped working completely. Is this just an issue where I need a new power source or is this thing messed up? I work overnight and need to be on ASAP but can’t figure it out. 

I have Xfinity 1000 down/100 up plan for over 3 months. I am connecting PC direct to SB8200 for testing and I only get a max of 24mbps upload. Only 1 (new) splitter and no other breaks in the line to the outside box, which has a new cable to the pole. Download is to spec and fine with no errors.Online Xfinity has reprovisioned the SB8200 at least 20 times and rebooted it at least 30 times over the last 3 months and I’ve logged around 22 hours on the phone with them.An Xfinity tech came to my house and tested everything and said it was all 100% and the reason I wasn’t getting 100mbps upload was likely to be Xfinity not provisioning it right.He verified upload 4 bonded channels at 45 dBmV within spec.To rule out the SB8200 I bought an S33 and had exactly the same result so I returned it.When I call them Xfinity is now telling me that the problem is the manufacturer needs to update the modem and they can do no more troubleshooting until that is done.

Bought the SB8200 on Amazon in February and it said two year warranty. Arris website says it has to be from Arris.com or authorized seller to be valid. So, is Amazon authorized? It’s starting to lose connection after working fine for 7 months. I see others having the same issue, must be built it obsolescence or lack of quality.

Modem purchased May 17, 2022.  Worked until recently when internet connection would drop several times a day.  Resetting modem several times would restore connection.  ISP checked their equipment and replaced incoming cable because speed was a little slow.  This did not solve problem.  Due to visitors arriving in a few days I purchased a new SB8200 and this resolved problem.  Original modem was purchased at Walmart for $169.00 but they were out of stock when the unit began to fail and replacement was purchased at Best Buy for $138.99.  Both retailers told me to contact the manufacturer to recover the replacement purchase cost.  How do I proceed with this warranty claim?

I have been talking to my ISP trying to figure my upload speed issue.  I am on the 1000mbps down and 100mbps up plan. However my upload is stalling at 20 mbps.  I am trying to find out what the upload speed capacity of this modem is. My ISP is xfinity. The lights for down is blue (docsis 3.1) my up is green (docsis 3.0) all other lights are solid green and the modem works great other than my upload speed.  can you tell me if this modem is capable for the 100 mbps upload? Is it because they have not activated 3.1 on the upload channel?

When I typed in the web address for the web manager, it went straight to it.  It did not require a login and there is not a tab to change the password.  Is this typical?
