Unable to login GUI page with default password

Brand new S33.  Installed it last night, and it wasn’t talking.  Woke up this morning, had not touched it, yet it was working fine. Proceeded to try logging in to https://192.168.100.1/Login.htmlI have carefully observed the serial number and tried to log in with the last 8 digits.  The serial number is in this format:block 1 - 4 characters, mixed letters and numbers - spaceblock 2 - 4 numbers - spaceblock 3 - 4 numbers - spaceblock 4 - 3 numbersAs such, the password I am using is the last digit of block 2, all 4 digits of block 3, and the 3 digits from block 4.  That does not work.  What am I missing here?

Second ethernet port on ARRIS SB8200

I just replaced the Xfinity equipment with my own ARRIS SB8200 and a Ubiquity Dream Machine SE router that feeds data lines wired in my home, with 5 end point mesh devices. No problem transitioning all my end use equipment over to one of the 4 networks I set up in the Dream Machine WITH ONE EXCEPTION - SONOS. The more I read, and I am not a techie, I see that there are incompatibility issues between Ubiquity and Sonos, so my desired solution is to connect a conventional wireless router to the second ethernet port on my SB8200, creating a wireless network apart from going through Ubiquity, totally dedicated to Sonos. Will this work? Seems it should if the second ethernet port has the same functionality as the first. Thanks in advance for any help here!

i have a question about warranty

We bought a arris surfboard model s33 in January 2022. Sunday it stopped working.  I work from home, virtual school for my kids, and don't have time for any shenanigans with my computer.  We went out and purchased another modem but I'm wondering if we have any recourse since this is only a little over a year old and they aren't cheap.  This is the second time this has happened but the first time I actually knew when it was purchased and approximately where although I don't have the original receipt. Am I just out because of a bad product or can I get a replacement 🤔?

connecting an sb6190 modem to an eero router

I accidentally unplugged my arris sb6190 modem. When I plugged it back in my network no longer works. It worked fine before I unplugged it.When I plugged it in, the top light (power) was solid green, then the next three lights flashed green, then the middle two went solid green, while the last one (network) flashed green. Eventually the power light went solid white, the middle two went solid blue and the bottom one went solid white. I have tried to power the modem up again and power cycle the eero router. I called my isp, spectrum. They can see the modem and sent a recycle to it. Same results - power light and network light solid white and the middle two lights are solid blue. The eero router light is flashing blue.I can see my network name on my devices but when I try to connect to it is just spins.Help - how do I fix this?

SB8200 normally has all green lights, today one is blue and no internet

We’ve used this modem for years with no issues like this. The buttons are always green. Today, we stopped getting internet service. The receiving light is blue, and the internet company is sending a tech, which is a huge inconvenience. Do I need to replace the modem? Thanks.

Unable to sign in when connecting

I'm having connectivity issues. I think there's some storm damage to my came lines. Because of that, I've been logging into my SB8200 often to look at the event log. I've noticed that I can't log in when the send LED is flashing. My PC just says it can't resolve the IP address.Is this normal? I can sign into it once the send LED is solid, but it doesn't make sense to me for the connection to the ISP to have any affect on the ability of my browser to find 192.168.100.1

S33 Xfinity says modem reset 200+ times in the last two days, constant T3 timeouts and packet loss.

For the last four weeks now I’ve been having T3 timeouts and packet loss. I was using a SB8200 and was told by xfinity that it could not handle the speeds I am receiving, so I purchased a new S33. After activation I was still getting T3 timeouts and packet loss.After many tech visits, we’ve replaced all lines and connections from the tap to and through my house to my modem and still I am having issues.I have checked the various guides and compared levels with what my modem shows and noticed the upstream power levels are slightly below what Arris says they should be, roughly 39-44 dBmV instead of the suggested 45 dBmV+.I spoke with an Xfinity supervisor today and they informed me that my S33 had reset over 200 times in the last 48 hours and says that their network techs have found no issues up to my tap. So I am wondering if maybe my S33 might be defective or if the slightly low upstream power levels are causing my problems.

ISP cant activate modem sb6190

I tried to add another Arris router to my home not knowing you can’t connect two modems. I have a large house and the internet is slow upstairs even with the mesh router. When I realized it didn’t work I tried to go back to using the arris surfboard SB6190. The lights are white, blue, blue, white however Xfinity says they can’t activate the modem. What happened that it worked fine before and now isn’t working? I have tried a hard reset and that didn’t work either.

Xfinity claims consumer modems (S33 in my case) are not mid-split ready.

Hello,After much back & forth with xfinity, they are telling me that the S33 is NOT mid split ready. Currently xfinity forces you to sub to xficomplete and use their XB7 or XB8 modem. Xfinity customer support:Cable modems need to be able to have the features to access the greater mid-split upstream bandwidth, and not all cable modems have that ability right now(Only our gateways). A modem will need to at least support DOCSIS 3.1. In other words, Retail modems do not yet support the new allocation. As this upgrade rolls out to more of our network in 2023, we anticipate the retail modem manufacturers will add mid-split to their modems and once they do so, you should then have retail device options available for higher upload.Any firmware needed to be compatible is built and approved by Arris. They are the ones you want to ask about compatibility and when they will add the feature/turn it on. My modem goes through several diplexer options on boot and is software ver TB01.03.001.10_012

app doesn’t reflect correct modem sb8200

Surfboard identifies my modem as a Motorola sb 6121 and my modem is an Arris sb8200. If that is wrong how can I trust anything else the app displays?

Downstream icon solid light on (blue) + internet icon solid light (green)

My wifi has been offline for 4 days. Xfinity reporter that on their end the internet system is on and successfully connected. They suggested to troubleshoot my surfboard. I rebooted several times - no luck. Should I factory reset? See title for status lights on my modem.

SB6190 in 2023

Since 2016 I have read many articles about the faulty SB6190 Puma 6 chipset and latency jitter issues.  I have also read many recent positive reviews of the modem.  Arris no longer advertises the Intel Chipset inside on the box or modem itself.  So now in 2023, did Arris stop using the alleged defective chipset for another chipset or are the latency jitter issues now resolved.  I don't know whether I made a mistake buying the modem on sale or the current versions of the modems have the problems resolved.  Most Forums talk about 2016, I would like to know the current status of the SB6190 in 2023. If anyone has the answers, thanks in advance.

S33 Xfinity Connected No Internet When devices wakes

Every Windows device in my home, two work laptops, a desktop using Wifi, and a hardwired desktop all will show “Connected, No Internet” for several minutes when first booting up or waking from sleep. The Xfinity tech that came out confirmed the signal is excellent where it is coming into the modem, and I have had the router replaced which leads me(and the tech) to believe its a modem issue. I have tried connecting directly to the modem to register its warranty but it wouldn’t let me and the ARRIS support site kept showing as unavailable. I just want to submit for a replacement.

Xfinity 800mbps service

Xfinity sent me an email saying that my SB8200 is not able to deliver the upgraded 800 mbps speed that I’m being offered.    Is that true and if so, any recommendations of the best value for money for a modem that DOES full use of the higher speeds? Thanks in advance for your helpJP

pairing to router sb8200

We have a new modem (SB8200) and intended to use our existing Netgear router they do not want to talk. Any advice?  Do we have to have an ARRIS router as well?  That does not make sense when my prior modem was not Netgear.

sb8200 no wifi and can't check warranty

Hello! I have an SB8200 Surfboard modem that seems to be non functional. I can connect to my wifi but I can't connect to the internet.The light are (top to bottom) Yellow, Blue, Yellow, Yellow, and the rest are offI'm pretty sure my warranty is still active but when I checked online it says it can't find the device. I've double and triple checked the serial number and it's exactly what it says on the modem. Every number. I'd even show the picture if It was safe to share the serial number but I'm not sure. I've tried adding spaces between the letters, I've tried using every other code on the modem even if it isn't labeled as the serial number, I've tried adding S/M: the the beginning of the number, I've tried adding zeros, removing numbers, putting letters in upper or lowercase, nothing has worked. This is the main reason I made this post

Arris sb8200 revision or version number?

Good morning, Have a brand new SB8200 that's never been opened but I purchased it in 2019 and its just been in storage. Want to replace the current SB6183 I am using with Charter Spectrum. I need to determine the revision or version number to make sure its at minimum version 2 per Charters approved modem list. I have checked on the box and the modem itself but there is no version number listed. Is there a way to determine the version number from the s/n, etc? I am pretty sure it will be fine as the 6183 I have been using has been working fine on the acct since 2014 but just want to be sure.Thanks

Customer Support

I had a problem with cable system which Xfinity fixed by running a new line.  Once activated, my modem connected to the internet but I’m unable to sign in to the modem.  I reset to factory default but it will not accept the default user id and password which came with modem (Admin / password).  I need to access in order to reset my home network.  I’ve tried unsuccessfully to contact anyone with Arris support for assistance or warranty.  I need the modem for work ASAP so will be forced to purchase a new modem (which wiill not be this company brand) unless I can get help immediately.
