SB8200 chat worked fine one day, np checking warrantyNext day will not accept the same info, so no way to chatAfter registration and proper activation using MFC MAC, drops from high speed to almost zero for 5 to 30 seconds or longer, happens every 2 to 5 minutes all day longI am almost ready to return but would love to chat before I do

I have been having issues with my SB6190 rebooting on its own lately.  It has been a great modem for a long time, but all of a sudden it is acting up.  I admit up front that I am not very tech savvy.  I know just enough to be dangerous.  I have read through various articles and one of the common things to try is to see if there is an update for the modem.  However, when I type in the IP address, I only get an Arris page with information on it, and no place to login.  I can go to a few tabs like Information, Configuration, etc., but none of them have a place to login.     I have tried starting the IP address with https, http, and just the number itself.  Any other number besides 192.168.100.0 just gives me a timed connection failure.  The 192.168.100.0 takes me to the Arris page I mentioned.  I am hoping someone might be able to tell me where I can find the login page now.  Thanks in advance for any help!

I just want to say I have an ARRIS (S33) that I purchased in June 2023. It broke in April 2025, still under warrantyBut I couldn’t find any way to contact you people at Arris  and life moved on and now that Cox has jacked my bill sky high for modem rental I remember that I hadn’t figured out how to contact youo (BECAUSE YOU MAKE IT VERY DIFFICULT) and the warranty has expiredThis is not good customer service.

My arris s34 keeps restarting every few minutes I only got it 3 weeks ago please help.  

I'm not able to get into my wifi don't know password 

Is there a customer service number?

I need a modem for new fiber service. Which one seems to work best? 

Not sure where to ask this question or if it should be a Question or a Conversation?? Either way, will try the General question forum. I had very slow upload speeds (SB6190) so when the Cox Communication Tech came out he replaced the entire cable and connections from the side of my house to the outside pole. I also had rebooted/reset my modem (a few times by the book) and removed the wireless router.  When he tested the system afterwards he said:You’re getting 32 good channels (or ?frequencies) down but only one channel/frequency up and that I should have four channels/frequencies up (SB6190)  I now have good up and down speeds but still wondering, does anyone know the answer as to why only one channel up?  

When trying to print from a new Brother L2420DW printer using the Surfboard SBG6700-AC modem, I get an error reading on my printer that says it “cannot detect a wireless router/access point that has WPS enabled.”  How do I enable WPS on my modem? Is it possible it is too old to have that capability?

S33 modem 3 months old. I am experienceing packet loss and lag that Xfinity cannot seem to figure out. I’m including a link to pingplotter data that appears to be showing the packet loss to be coming from hop 2. Is this my modem or is it Xfinity equipment? Ping plotter data What started all of this is that I’m getting packet loss and lag errors while inside the iRacing sim. I believe it is on the upload side as I’m not having any issues with seeing the other cars on track however other users are reporting that they are seiing my car blinking or disappearing at times. Also in the modem has the following 2 errors in the event log that I’m not sure what they mean or if they even apply to the packet loss. RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=10:e1:77:95:3

Upgrade my service added this new modem. Internet keeps dropping and it can’t reach all of my new cameras. It worse than before I upgraded.

Lost power this weekend (it was connected to an APC UPS) and after reboot the SB8200 steady blinks (all 4 LEDs and the Ethernet ports).  There doesn't seem to be any decernabIe pattern.  I also can't get DHCP directly connected to a computer or communicate with a static IP.  Did the 10 sec hold several times on the reset button to do a factory reset.  Behavior continues and is persistent regardless of what's attached to the modem.  Device is still under warranty per this site.

My iMac, Aura frame and Roku stream bar all show as connected to Surfboard, but our iPhones do not. Why?

Why does it say my network is not connected to the internet? 

no connection to Samsung TV after power outage .. contacted Xfinity and they say the signal is strong so must be an issue with the router/modemArris Surfboard AX300

I had an xfinity tech out today to confirm my modem died. It simply doesn't work, although it showcases it’s fine via the light on front. How does one go about getting it repaired?Thanks in advance. Lance

What is the phone number to Arris? The number on their website and will not connect….

If its not, which model is? Please

SB8200 I did a factory reset because i couldn’t find my notes on the password i had created and the passwords online were not working. I disconnected the coax before the factory reset.  Tried logging in….browser says it can’t reach it even though i am connected to it via CAT 7. I am getting this error:   PR_CONNECT_RESET_ERROR I have tried both Edge and Firefox.I connected the coax and get online but still cannot get to the login page of the modem.  I want to confirm the mHz that it is operating at to make sure it is in the acceptable range for Comcast.

I suspect my SB8200 purchased in 2024 is starting to fail, but I cannot contact customer support due to the website saying my serial number cannot be found. I have tried entering it multiple times in different formats with no luck.

I have a new modem within that last 6 months and the power cable is now bad. I have a multimeter and am not getting 12 VDC

Internet was working great, had a brief power outage and disconnected SB6141 surfboard modem. I’ve tried unplugging the power and Ethernet and replugging and the only lights are the send and receive (both blue) and the link light is flashing blue. When it starts up the power light starts green but goes blank. Please help!

Model: SB8200All of a sudden stopped working. Checked lights, all of them were lit. Unplugged for 10 seconds. Now it shows power button solid green, transmit light blinking, receiving light and internet globe no lights just blank. Tried holding the tiny white reset button in the back until all lights in the front flashed.tried without any wifi extenders plugged into ethernet, still no luck. I’ve had this modem for quite a while at least 3-4 years.

I have a 5G wifi network and just bought a security camera that does not work on 5G.  It needs to connect to 2.4GHZ.  The back of the box shows that it has “Antenna Configuration MIMO (multiple In, Multiple  Out) for 2x2 on 2.4Ghz and 2x2 on 5.0 GHz,  How do I connect by security camera to th3 2.4GHZ without disrupting the 5.0 GHz for my regular Wifi use.

My Arris Surfboard S33v3 cable modem started flashing the green light and I am unable to get the WiFi connection now. Checked the IPv4 Address and it starts with 192 … as expected. Checked connections and they appear OK. Installed 3/7/25. Suggestions?
