Modems

Looking for a live chat so I can get this modem running again  

Can the running lights of modem TG2482A be dimmed?

Two ports on back. 1GPS and “up to” 2.5 GPS. The 2.5 port implies I can hook up my 1GPS service into that port since it’s “up to” 2.5. Sometimes the cable provider exceeds the speed I’ve subscribed to. I saw it a lot when I was in the 500 MB/s plan. It’d go to 600-700. So now I have the 1GBPS plan. Should I plug into the 2.5?

I am getting multiple errors No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.1;along with periodic MTA PROV: Failed.I have a T25 directly connected to cable from wall with SN: **** **** **** ****Comcast has visited multiple times and says speed to the modem is 800+ The modem is connected to eero 6 gateway.  I am constantly getting connection interrupted on laptop and download speeds < 100. Are these messages related or is there any compatibility issues with eero or settings I need to change. (edit: CM-MAC information removed)

Hi All,  I purchased and installed S33 in February. It worked well. However, for March and April, Xfinity reported that 3x-4x data usage than before (and charged for additional data). My router reported 1/4-1/3 of the data usage. So I called Xfinity to see why there is a difference in data usage being reported. Xfinity said it was because the S33 did not report data usage correctly. Does anyone know how to solve this problem? Or is this a problem with the S33?Thanks all for your help. 

I am struggling lately with disconnects on my S33.  The cable connection coming in to the house was terminated by Cox and there are no splitters or any other devices on the line.  The connection is from the box at the street to the house to the modem.  Despite the constant issues, Cox claims it is my modem because they are able to reach it with a reset packet and if they can do that, there is absolutely nothing wrong with their service at all.  Yes, it works sometimes, but many interruptions throughout the day.  The modem is less than two years old because I replaced it last time they told me to.  I’m not convinced another modem will solve my issues.  I have the following types of log messages on the S33 Event Log: Started Unicast Maintenance Ranging - No Response received - T3 time-out; SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing; MDD message timeout;Is there any other info I can provide to help tr

After an apple security update this morning, neither my iPhone or my MacBook can sign on to the household’s Wi-Fi. I am getting “invalid password” message. My Amazon Alexis is still connected. Do I need to change the passcode/password and how do I do that. I have a SB8200 modem with Linksys router. 

I am getting disconnected multiple times a day for a couple minutes at a time.  The light is staying blue the entire time.  This is happening on a hardwired device.

I have 1000 gbps but my modem only puts out 400. I have reached out to Xfinity and they said that everything is fine on their end. Can you help?

I am trying to connect a TP-Link XE75 Pro to my S33 Cable Modem. It wants to know the internet type and I contacted Xfinity and they told me that since it is not a modem provided by them, they cannot give me that information. They told me to contact Arris.

I am attempting to install an Synology NAS on my system. I can see the NAS on my computer, but the NAS unit (DS923+) cant access the internet. It's like the router is blocking it somehow. No problems with accessing the internet on the computer or via wifi. I am not well versed on this NAS stuff so any help would be great.

We have an Arris modem with an Eero Router. Our internet speeds when we are able to get on is fantastic.  We hare constantly having problems with the internet going out.  We had Xfinity out to troubleshoot.  They said on their end everything is working 100% fine.  They said just make sure your software in the modem is up to date.  The Eero is up to date.  Ive been trying to log into the Arris to do the same, and I can’t access it.  The message “check again after 5 minutes invalid login and password”.  I’m fairly capable to trouble shoot this.  I’m just worried about hackers since it’s not a secure site.  Anyone else have this issue?

We've had our s33 for about a year , love it, works great ...tonight while watching TV one of the cats ran passed it and unplugged it, plugging it back in now results in just a green flashing light and no internet, Xfinity can't see it at their end and can't provision it again, I've done a factory reset but it's made no difference. In the web interface it says that DOCSIS network access is denied and also the system date and time is set to Jan 1 1970 but I can't see any way to correct that? Everything else looks normal to me

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!
