Internet dropping out frequently

My SB6141 seems to be acting up, though all lights indicate no issues. I’ve had issues with internet dropping out frequently for brief periods throughout the day over the past few weeks. I thought is was an issue with my Google Wifi routers, so I replaced them with Eero. But the problem persists. Could this be a firmware issue? Any solves beyond frequent power cycling and prayers for a tenable work from home experience? There are no indications of issues with the router, it is not running hot and speeds (when it is working) remain consistent. Thanks!

Complete factory reset

How can I perform a complete factory reset that will return the WiFi name and password to the information listed on the gateway modem? I cannot remember the user name and passkey I set up and the admin reset does not work to reset the user name and passkey.

Arris Touchstone CM820A/NA Cable Modem: Does it Have a Built-In MoCA® Immunity/POE Filter?

I have a question regarding my Arris Touchstone Cable Modem (Model # CM820A/NA), and can’t find any related information here or elsewhere online. I installed MoCA adapters into my home network to replace the powerline network adapters that stopped working.  While preparing to install the MoCA adapters, I read that it's recommended to install a POE filter at the cable service entry point to help block interference from nearby homes.  I also read that some cable modems have these filters built-in, so I'm trying to determine if mine does. I read somewhere that the CM820A modem has a built-in MoCA® Immunity Filter.  Unfortunately, the online specifications for the CM820A/NA don't mention the filter, so I'm not sure if it has one. I can't find anything describing the differences between the CM820A and the CM820A/NA, so I can't tell if my CM820A/NA has one of these filters built-in.  I'm also not sure if the CM820A and the CM820A/NA are the same modem, or if they are different.  It seems tha

Difference between the options "restart router" and "reboot device".

I would like to know what is the difference between these two options, because they appear to make the same function.

SB6141- unable to find my network

I  moved addresses recently, but am using Comcast/Xfinity as my  cable provider in both places.  My Arris SD6141 was working fine at Address 1 but not at Address 2.  Comcast entered the modem into their system (I had to create a new Comcast account).  They can find my modem, but I can’t pick up my system on any of my devices. My network name doesn’t show up on any of my devices.  Any suggestions?  Comcast said they can’t do anything on their end.  Is it time for me to simply replace my modem and start over?  Any help would be appreciated.

I am ready to install my new modem, do I have to contact my Service Provider?

 It is possible that you need to contact your service provider.Using the SURFboard Central mobile app, the self-serve portal works with Comcast, Charter and Cox most of the time.For other service providers, you may need to contact.  The App helps you get the information you will need if you call.
