SB6190 Signal Levels

Hi folks, I just found Arris’ specifications for SB6190 signal levels here. It says the Downstream Bonded Channels power should be between -15dBmV and +15dBmV.  My power levels are at 11.X dBmV to 13.X dBmV.  However, in the provided example, it shows -0.1dBmv to +0.2dBmv.  So my question is this?  Should my downstream power levels be between -0.15dBmV and +0.15dBmV or should it be between -15.0 dBmV and +15.0 dBmV?  If it’s NOT the latter, then I should be calling Cox.

SB6190 - Internet drops out with increasing frequency, all lights remain solid

Hello there, can anyone help me interpret my upstream/downstream logs? My internet keeps dropping out with greater and greater frequency it seems. If it’s important, when the internet briefly goes out, the lights on my modem and router remain on/solid. Recently, there are times when it doesn’t connect back automatically and then I have to establish a connection again via my router. I just purchased my router in March of 2021. I received the modem (SB6190) from a friend in 2019 and have had no issues until recently. It looks like the Upstream Bonded Channels are lower than the accepted levels, but I’m not quite sure what that means. I also refreshed the page after 10+ minutes and provided both reports below. For Upstream Bonded Channels on the first report, it shows no readings for channels 1-3. Thanks so much in advance!  Startup Procedure Procedure Status Comment Acquire Downstream Channel   Locked Connectivity State OK Operational Boot State OK Operational Confi

wifi Lights not on Modem

The only light on my modem/router which turns on is the power light, The wifi lights do not come on and when Iook at the username “network” it said that it is out of area even though it is in the same room and has always worked previously. Modem/router is Arris Model TG 1682G. Operating system is Windows 11. How can I get internet back and the lights on the modem/router turned on?

Newly activated SB8200. Channel 24 is missing. 25 is not locked and 23 has 3127368446 Correctables

I just had this activated last night and having some channel issues and only the downstream light is blue. The upstream light is green. Spectrum  says they don’t see any problems. Is this normal?

Top and bottom lights

New SB6183 with Xfinity wi-fi. After instal, and several resstarts by me and Comcast, the top and bottom lights are white, not green. The system restarts on its own periodically, sometimes repeatedly. Can you tell me if the lights are a concern?

Replaced Arris Modem and SW Download Failure

First off, sorry for the length of this post. I posted the question below on the Charter Spectrum Community a couple of days ago and two different Spectrum employees responded. At the bottom is Charter Spectrum’s response that I contact Arris. Hoping someone can help with the error messages.Question to Charter Spectrum Community. Last Wednesday August 24, I replaced our outdated Arris SB6141 with a Arris SB6183. Our service has went from 100 Mbps to 200 Mbps over the last 4 months. The old SB6141 handled that upgrade fine. But then the announcement from Spectrum stating our service got 50% faster by an immediate 300 Mbps upgrade. The old "unsupported" SB6141 did not handle that, hence the upgrade of our modem to the Spectrum supported SB6183. This modem was also recommended by a Charter Spectrum technician last June. I used the activate[dot]Spectrum[dot]net page and all was successful. We now have 330 Mbps speeds.My question is that on the Friday after our upgrade we are repeatedly see

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!

SurfBoard SB8200 wifi works but not ethernet

I have my Surf Board connected to a router and can get Wi-Fi internet just fine.  But all of my Ethernet wires throughout the house connected to the router aren’t receiving a signal.  I tried plugging in an Ethernet cable straight to my laptop and still no internet.  I’ve tried resetting and rebooting both the modem and router and still no internet through Ethernet.  What am I missing?

SB6190 Sneaky question...

I’ve had a Arris SB6190 paired with a Arris SBR-AC1990P router for about 5 years. Yes, this question is really about the router, but it definitely is triggered by the modem, and I didn’t see another appropriate place to post it.In the last week, I haven’t been able to enter the admin page of the router. I can get to the login page at the default address, but when I hit the “enter” key on the keyboard (after adding username/pass) or click the mouse on the “Login” button, I get the error “Can’t open page because the server dropped the connection”. However, if I remove the the Enet cable on the WAN connection coming from the SB6190, and then access the router, I can login to the router just fine. I can make and save changes. But as one can imagine, it’s a hassle. I’ve tried rebooting (both devices), restoring factory defaults (both devices). The addresses of the two devices are the default addresses, subnet masking is set to the default.Any ideas how to fix?Thanks!

S33 resets when using computer

This is my second S33, the first one died after about 8 months of use.  I have my household running off this modem with a set of (3) Arris AX 11000 routers. It seems every time I sit down at the computer which is actually plugged into the router the S33 will reset. This will happen frequently but ONLY when the computer is on and connected to the router. Today it has reset twice. I can shut down the computer and go weeks, even months without a problem. Then turn on the computer and within an hour or so the S33 will reset.

Is SB8200 speed limited to 800mbs?

just tried a Arris SB8200 on Vyve cable's gig plan (they say max of 960mps).I couldn't get above about 600mbs so Vyve sent out a tech who replaced something on the pole feed (anyone know what that might be?) That got me up to the 800 neighborhood but no further. Thinkin it might be modem prob so so contacted Arris tech support.  He said (and confirmed when I asked a different way) that the SB8200 would not go above 800mbs on several major carriers result of a technical implementation.The tech said that I had two options:Change vyve plan to one that had max of 800 mbs, or:Buy another Arris (also DOCSIS 3.1) modem - the Arris S33.Clearly, although a modem is advertised as DOCSIS 3.1 compliant, who knows what speed you can get in the home/office installation.any way for me to get full speed from the gig plan or do I have to buy (yet) another modem???  ///

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

Does the 6190 Surfboard allow user to update firmware?

My 2 year old Surboard 6190 modem has been dropping connections lately and I’ve not been able to return it to stable performance. It’ll be fine for a while and then drop repeatedly for a hour just because.I’ve done the unplug/plugin and the hard reset without improving the stability, the cable provider confirms no service interruptions and the tv which comes through the same line is unaffected.In the past, this type of behavior was a sign that firmware needed update, but I cant even figure out if this product allows or requires firmware update. Nothing is here where it would be expected   : https://arris.secure.force.com/consumers/ConsumerProductDetail?p=a0ha000000REMs8AAH#panel4Searching Arris and various online sources finds no clear answer, the possibilities are:The modem requires no updating, it’s automatic The modem requires the user to manually update the firmware The cable company pushes updates to the modem, (but possibly only if they own the equipment, if not it’s unclear what

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.

As the post states, I can’t see the modem...maybe because I can’t see it through my router? Am trying to connect via wifi, should I connect hard to the modem itself? I don’t see a cable input to do that.
