According to Cox Internet, I need to “enable” IPv6 on my modem using the Admin console.Unfortunately, the “official” documentation they sent me (https://routerexperts.net/arris-router-enable-ipv6/) seems non-applicable to the situation.The online /phone /chat support drones can’t seem to understand how to even spell IPv6, they just keep saying that _I_ have to configure it on my end.Can anyone help with documentation links or other tips /tricks for figuring out what range and prefix is being advertised to my modem?

how to get DOCSIS 3.1 to display

I have a new modem on Optimum 400mb service. My older modem registered fine but the new 8200 is not picking up DOCSIS 3.1 even though the provider says it is being used. How do you resolve this. Support telephone number is useless!

SIP phone

The modem isn’t allowing an IP address to be given to my SIP phone that is connected via ethernet cable. I verified with the internet provider no connection issue. Any help?

pay for 300 Mbps, only getting 250

I have Spectrum; I pay for 300 Mbps (w/only 10Mbps up). I have an Arris 6141 which claims to be able to do 343 Mbps. I can't seem to clock more than 255 Mbps. Should I call Spectrum, should I try another modem, or should I just be happy I'm getting 85%.(Just in case anyone asks: I did plug a laptop directly into the ethernet line coming from the modem: I'm not going through any router).

is the SB8200 affecting the Wi-FI?

I have xfinity and using a SB8200 and a TP-Link AX3000 besides for Wi-FI I also have the 2 laptops and an TV connected to the AX3000 My Wi-Fi is going from 800Mbps to ZERO randomly and frequently , even after I run reboots on both the SB8200 and the AX3000. all firware is up to date. Please note that the devices connected to the AX3000 continue to run strong even when there’s no Wi-Fi this is the 3rd router I’ve had this happen to in the past 2 years so i’m thinking it’s not the router any longer. Has anyone had this experience with an SB?

403 Forbidden

If I try to load the ARRIS SB6190 Web Manager Access page 192.168.100.1 I get "403 Forbidden" (tried multiple browsers). I’m assuming that when xfinity reprovisioned for internet access, it locked me out from looking at or making any changes to the modem’s configuration? Does that sound right? Currently, my ISP speeds are about 1% of what they had been (using the same modem) up until now (download 0.5Mbps vs 89.3Mbps). I am testing the speed with the modem connected directly to my PC (ethernet cable). I’m about to use the RESET button on the back of my SB6190 (which is what was recommended to me once before by ARRIS for an earlier Surfboard modem I was using that had a similar problem). After the reset, I plan to used the xfinity mobile app to reprovision for internet access. Does that also sound right? Thanks.

Internet Connectivity via WiFi

I’m using Spectrum as my ISP. I use a SB8200 modem. As of this morning, internet through my wifi stopped working. When I run directly from the modem to my laptop via ethernet, I’m able to get internet without a problem. I did all the routine steps to cycle both modem and router, including factory restoring both. And I tried 3 different cables between the modem and router. I figured the router (Linksys EA8300) must be the problem, so I went out and bought a new router (Netgear Nighthawk RAXE300). Same problem. WiFi works fine, but no internet.The router shows a solid red internet light, indicating it’s detected the connection but isn’t receiving internet connection. I’m struggling to understand how going to my pc through the same LAN port, I get internet. Connecting to the router it does not recognize the internet connection. What am I missing? My family is losing their collective minds. Any ideas?

Find browser history on router

I understand it’s possible to find browser history on my router. Can someone tell me where I could find this on my Arris router? I’ve clicked through every where I know to look but can’t find it. It says I have a DG 3450A? Thanks!

Firmware update

I have a Surfboard SB6190 modem. I understand the ISP has to do any firmware updating but is there a way to determine if the firmware is up to date?

Voice service modem that is equivalent of S33?

The S33 with its two 2.5G ports is one of the best modems you can get with a gigabit internet connection. Will there be any options coming soon that will offer similar performance but with the xfinity voice support? Or am I just limiting my ability to make use of such a connection by having xfinity voice?

VIP7802

I'm a Bell Fibe TV (internet) customer. Bell provided a VIP7802 Arris android tv unit. It is connected to Bell's Home Hub 3000 modem via ethernet cable and my Samsung smart tv via HDMI cable. When I turn off both the VIP7802 and TV using Bell's TV remote why do both turn back on by themselves within 1-2 minutes?

Change, settings (especially security)

Even following the instructions exactly, (I bought this year’s ago so there’s no way it’s under warranty, so to get any support at all from the manufacture of this product I have to pay for it, (warranty period x2 years and I’ve had this for almost x4 years), and I’m experiencing the following; I can’t even log on, ) 192.168.100.1), in order to revise the factory settings. Even after “resetting” nothing happens. I’ve tried completely disconnecting everything and allowing it to completely cool so it only warms to room temperature and nothing.

Surfboard SB6121 making chirping noise

I just bought a new laptop and the modem starts to make a chirping noise, just now as I connected new laptop with Ethernet cable.Last week I used a Lenovo laptop, connected with a USB to Ethernet adapter…. and all was well, no chirping.Is it possible this new laptop has something different with the Ethernet port… I can’t explain it why the modem is just now making this noise?Thanks,Yvonne

What is the download and upload speed of the SB6183? The page lists two different speeds

This page for the SB6183 at the top lists the download speed as 686Mbps but if you scroll down to the specs it lists the download speed as 400Mbps, so which is it? https://shop.surfboard.com/sb6183-surfboard-cable-modem/. Also this other page lists 400Mbps as well https://www.surfboard.com/products/cable-modems/sb6183/ but during speed tests, I can get over 500Mbps so that makes me think it is 686Mbps but all the pages make this pretty confusing. Also, what is the max upload speed? Since there are fewer upstream channels in the modem than downstream channels, the max upload speed is usually less than the download speed. Based on this article, I’m guessing 200Mbps but does anyone know for sure? https://kb.netgear.com/000060401/What-is-the-difference-between-DOCSIS-3-0-and-3-1

S33 light is blue, but no internet connection. Xfinity

This has happened a few times now, but this time it has not come back on after 12 hours. Router indicating no internet, and attempts at using wired ethernet connection have failed. Oddly enough the light remains blue even when I disconnect the coaxial cable. The unit is only about a year old. Any ideas?

Xfinity and S33 modem slow speeds

I’ve got the infamous 1.2gig service from Xfinity, they have checked and replaced everything they have changed the channel that my box connects to to their service, my speeds have not exceeded 500 mbps which is less than half. I thought it was a double NAT issue because they can only provide their own gateway modems which act as routers as well, but it’s still happening with the new S33 Arris modem I purchased just last week. Is anyone else having this problem? Is there a quick fix to cause the modem to recognize at what speeds it should be getting?I have the app, but it’s no help for this problem whatsoever.

My S33 requests an option that Optimum DHCP doesn’t support.
