Modems

UPnP is unsuccessful how to fix the problem

I need to disable sip alg on my modem i have the arris sb8200

I contacted Xfinity because my network is not showing up on my computer nor phone, and I have no clue what the password is on my SB6190. Xfinity said they tripled checked everything, and my modem is showing online but, I have no network showing on my computer nor phone.  We restarted the modem over and over and still nothing, and they did a lot of troubleshooting.  For a brief second, surfboard came up, but it disappeared.  They said to contact you guys but, of course it’s a Saturday and no one is available. How do I find my network and what do I need to do?   I would really appreciate some suggestions.  

I have a Arris OBBD Router that I need to have the PW reset.

I have an Arris DOCSIS modem on ComcastSoftware Image Name:AR01.05.020.13_032624_735.NCS.20Model:G36The upload speed has been poor since I purchased the modem last year.  5-6 Mbps is typicalDownload speed is 700+ Mbps.   My previous rental modem from Comcast got around 300Mbps upload speed.   Comcast came out to check the connection & found no problems.   When the technician connected hist modem, he got about 320 Mbps upload. Do a need a replacement modem from Arris? 

I have had the same Internet service, the same modem, the same router and all of the same devices in my house since I moved in over two years ago. Last month, one of my TVs, one of my ring cameras, and one of my smart outlets stopped working. All at the same time. When I search for the network on these devices the network does not even pop up as an option to connect to, however, at the same time the network is popping up on my phone my other TVs, my other cameras, my computer, computers, etc. It is literally just the one TV, the one camera and the one smart outlet that do not work. They do not connect to the Wi-Fi network. I reached out to my Internet service and they said everything is fine that it’s either a problem with the modem or a problem with the devices. I find it hard to believe that three different devices all failed at the same exact time which leads me to believe that it’s a modem issue. When I was doing some research, I found that some devices only can support 2 GB spe

I am not able to sign into my routers GUI (192.168.0.1) . I login with the correct credentials and it gives me an error of "you must sign in first". Then when I try to log back in, it says someone is already logged in. Please assist! Thank you,W. Bower

Forgot email to login to modem setyings

I tried calling the number it gives with the error, but it just hangs up.

What type of security is my router 

All of the official retailers are out of stock.  They all seem to have the older S33 though.  Does anyone know what is going on?

I just set up a Surfboard S33.  After just a half hour or so, it was already hot.  Does this commonly happen with this model? Should I return it?

I have had trouble with my modem not accessing the internet each light would flash and go solid until the internet light, when it tries to look for the internet it flashes faster than the others and then resets back to upload a couple times before going back to download and trying it all over again I have factory reset it and contacted spectrum do I need to contact someone and then have customer support reset it themselves?

I cannot open my Netflix acct to play a movie. Csn you update your firmware?

Trying to download the app on a new cell phone which is different than the one I originally used to set up the device but its keeps  kicking me out.. DO I need to restore the device to factory settings and then start over? 

Iam experiencing issues with my internet. My ISP just verified my internet connection with another modem, but when I try to use my Arris S33v2, it does not work properly. I dialed the number I found online (1-877-466-8646), but the call got disconnected after 6,7 seconds. Can someone share another way to contact Arris Tech Support?   

I have seen all the other threads about how to access the modem and tried them all.I tried ip addresses 192.168.100.1, 192.168.1.1, and 192.168.0.1 with no success.I have tried connecting directly to the modem. I have tired disconnecting the coax, being directly connected, and it loading the login page but the moment i connect it back to the internet i can no longer access the login page. is there something my ISP is doing to prevent me from logging in? I really need to get into that data but I am out of ideas how. 

The SB8200 is not listed as a choice on initial setup. Help!

The power company was messing around up the block today, and they shut the power off to our neighborhood for a short time. Our S33 cable modem is now solid orange for different intervals, flashing white in between. Sometimes it’s orange for seven seconds before flashing light, and sometimes it’s orange for over 20 seconds before flashing white. Sometimes it’s orange for over a minute before flashing white. It seems random. I’ve tried power cycling it, but it hasn’t helped.

Had an S34 running great on Xfinity network until they decided to “upgrade” the system in our area in 12/25.  After upgrade S34 was “seen” on the Xfinity network but no internet at all.  After several Xfinity service calls can get an internet signal and run a few apps via S34, but not all apps will function; can’t get internet signal to router.  Of course the Xfinity modem (that I got to diagnose) runs ok.  Any similar experiences and/or solutions?

Bought this device in June 2025 this morning it has died. Contacted Optimum to see if there was something they could do. They couldnt see the device. It will power on and then flash blue up/down stream lights and then reboot and start the cycle of flashing again.  Optimum reconnected my SB6183 and it is working fine.  When putting the S/N in it says  “We were unable to locate your serial number. Please check your model number and serial number and try again. This information can be found on the label in back or on the bottom of your device.”  

I have  SN8200. lost Internet I have reset it been in touch with service provider. They have tried to reset it. The power light comes on, but the Internet lights do not come on they flash intermittently, but do not stay on. I have reset it to factory default powered it down checked with my service provider Internet to my house is fine. Just making a squeaky noise like it’s trying to connect, but nothing is happening

The power company shut off my power for several minutes to test for a possible issue. My internet worked fine beforehand, but after reconnecting power, my Arris Surfboard 33 no longer connects. I’ve tried several resets with no luck. We have Cox, but their remote help was not useful. Help?

My brand-new S34 modem is disconnecting for 5-10 minutes about twice every hour.  Xfinity already came out, but may need to come back.  Based on the SNR data, and the Event Log entries, can someone tell me if my problem is comms with my router, or Xfinity?  TIA,TomSNR data (partial, but typical):Chan    Status    Modul.    Freq.        SigStr.        MER     Corr.Err.    Uncorr.
