Why my modem SB8200 Reboot for no reason

I have purchased a brand new SURFBoard SB8200. But lately i have been having several interruptions on my connectivity, where it seems the modem reboots itself. This is causing me a lot of issues I am running my own business, and multiple occasions this reboot, interrupted my zoom session (this is not professionals), it does not reflect well on my Company. Please advise why this is becoming an issue.

intermittent internet connection on sb8200

New sb8200 the lower blue light turned green after 3 weeks use. Provider wifi has a good signal. I checked. The eero extenders are on as a few devices have signal and are working! I have unplugged the modem and pushed in the reset button several times to no avail. Down stairs tv on signal, upstairs tv has signal. What gives?

SB8200 Unable to Login / create new password

Trying to log into an active modem by using the browser. Used the default password (last 8 s/n) and then it immediately prompts me to change the password; I’m good with that. But when I enter the new password (example Abc#1234) is continues to prompt me to enter a valid password. According to the displayed syntax it is correct. I’ve tried multiple variations and when I leave something out the correct error message displays (such as numeric required, etc.). I’m stuck in an infinite loop; every time I use a valid password I continue to get the popup “192.168.100.1 says Please enter a valid New Password.” Modem is running fine so I don’t want to reset the modem. Any suggestions for a solution?

(SB8200) Packet Loss Out,

Let me start by saying that I have purchased a new SB8200, had a tech replace the coax in the wall and he also provided me with a new cable. My modem signal levels, and I forget the exact values he specifically mentioned, are in the dead center of the allowed ranges. “Perfect” is how he described them (for what that's worth) because they could fluctuate and still be within the desired range.I did not have any issues with packet loss until I purchased 3.1 modems. I also own a g36 and experience the same phenomenon of 1-4% packet loss out at rather constant rate. I do not game with a router and I unplugged directly into the modem itself. I have tried different ethernet cords. I have also used the hidden troubleshoot menu on my series x and completely factory reset it… twice.I recently read a thread that someone else with a 3.1 modem was experiencing packet loss out as well. My very loose “theory" is that AQM, active Queue Management, is dropping packets in order to ensure ping times don'

SB 8200 Version number? And no support options?

I cant find a clear answer on versions for SB8200. Other questions have been asked but no clear answer. Need v3 as preferred for Spectrum. And am I correct that there is no way to contact Arris support unless you pay for the support tier? Thanks !

Unable to connect laptop with SB8200

I’m not able to connect my new SB8200 to my laptop to activate it. The top light is green, the 2nd one is blue and the other 2 stay green (it should be white - blue - blue -white). I’ve restarted it multiple times and also used the reset button but nothing changes. I can reconnect my old SB6190 using the exact same connections and it works fine. Any suggestions?

Need Assistance configuring 2nd ethernet port my Arris Surfboard SB8200

I just purchased the Arris Surfboard SB8200 modem. Comcast has already registered and configured on their end. I have two ports on the modem, I have one port direct connected to my wife’s work computer that has an IP address. The other port is to my router for WiFi which is not getting an IP address for it. I was informed to call ARRIS to configure the new modem. I’m waiting on hold for a support rep now. Figure I can get some answers/help from the community.

New Ooma Telo Won't Connect With Arris SB8200

I’ve had an Ooma Telo VOIP router for making phone calls for over a decade. Recently my Ooma Telo started acting up, requiring frequent reboots to get my phone system to work. In response I ordered a new Ooma Telo but was unable to get it to work with my Arris 8200. After three hours of phone calls to the technical support folks at Ooma, I was sent the following instructions:“Please also check and make sure that the firewall on your modem and/or router have been disabled. Ooma uses the following application ports for outbound data and voice traffic:UDP and TCP So you need to make sure those service ports are open on your internet connection”Has anyone else encountered this difficulty? My first thought was that the new Ooma Telo might be defective.
