Modems

I have a SB8200 modem that I’m trying to access the MAC filter to add a MAC ID to give my thermostat access to the internet to control the thermostat from my phone.  Honeywell and my internet provider claim they can’t help me.  How do I find access the MAC filtering in my modem?

The power light will briefly turn on and then all other lights will flash together then all lights will go out. The modem will continue to do this every few seconds. Is this a hardware or ISP issue?

I’m trying to connect a HP 3056A for wireless printing. I expected to see a WPS button on the physical device, then expected to see a button on the https://192.168.100.1/ settings page. Didn’t see that anywhere, nor Surfboard Central app. There is also an option on the HP printer for a printer pin that I’m supposed to enter on the router settings. I looked on Surfboard Central for my W121 mesh network, didn’t see anything. Can someone point me in the right direction?

As the Title says, checking my event log after provisioning was complete showed SW Upgrade Failed. Is this an issue with Spectrum not pushing the correct firmware? Has anyone else experienced this?

Have had SB8200 for a year - has worked perfect until recently, when it drops the connection multiple times per day - and all the front panel lights say everything is fine.  SB8200 in warranty, Arris support checked everything and found all was good with the incoming signal. This was after asking me to have the ISP to send a re-activation signal and monitor for 48 hours (which I did - any experienced more dropouts). But they now want my ISP to come out and install a test modem for 24 hours - at cost $$$ to me, of course.  I don’t know why, we experienced a dropout while on the support call.  Clearly support does not have direction to actually help customers, but rather keep trying to point the finger somewhere else.  Any way to just get a replacement?  

Testing the SB200 when only power and ethernet connected.  Unit reboots after 10 minutes.  Is this normal behavior when no coxial is connected?  This is my second purchased one.  Many thanks.

Ch 2 showing Not locked, all levels look good.Had issues with ISP, replaced the line from the drop and tap, and had to call the fcc to actually have them come out and fix the node, just want to make sure everything looks good. currently the line has 2 splitters, just wondering if the node adjustment could have affected the configuration with my line.

We had a brief power outage to our home over night. When trying to connect to the internet in the morning, we had no connection, or intermittent connections. I rebooted the SP8200 and also did a reset. I contacted our provider, Breezeline, who said there were no outages in the area. They trying to reset the connect from their end twice. The connection would come back briefly and then fail. Finally the provider eventually said that it was the modem, and that I had to contact the manufacturer, Arris, to determine the problem. This is where we stand at the moment.

how to put a user name and change the password on my new router

I have an Arris SB8200 and if I wire my Xbox directly to my modem my router stops receiving internet so I cannot get wifi. I've done a reset and unplugged everything in every combination i can. When I get my router to work as soon as I turn on my Xbox my router disconnects and I have to reboot everything. I cannot get both to work at the same time while connected to the modem. Does anyone have ideas or solutions? I just would prefer to have my Xbox wired to my modem rather than through my router if possible. It does work if I hook it up through the router my connection just isn't as good.

Hey folks , I can’t access my modem login when I type it into my browsers address bar my browser says “site not secure” and won’t let me proceed. Any help I can receive is greatly appreciated!

Security search revealed vulnerability due to open port -- how do I close it?

I just purchased an ARRIS SB8200 Surf Board modem and having trouble activating.  To activate, I have two choices….Scan the QR Code or do it manually.  There is no QR Code and when I try manually...it does not recognize my wi-fi password.Is there a way to get the QR Code for the SB8200? 

Need instructions on sb 8200

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?

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!

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 🤔?

I have Centurylink $50/mo and was wondering since it is not cable if I can still use this modem? Tks Jane

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? 

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. 

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

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.

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. 

Trying to find out of above cable modem has any updates and if so do they download automatically. If not where can i locate them. 

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 op
