Modem activation Sb6190

Hello, I have followed the instructions to activate my modem - SB6190.  The middle two lights are blue.  The online & power buttons are white.  I do not have internet access.  In addition, the setup instructions requested I use the COAX cable provided by my network provider.  In doing so, I had to unplug the coax cable from my router as I only have one Coax outlet In my apartment.  I believe this has now resulted in my router being disconnected as well.   Please advise.

Internet randomly drops and speeds are slow - S33

S33 & Xfinity gigabyte plan Past few days  I have been experiencing frequent outages. Usually a reboot of the modem and routers resolves it but the past few times the speeds are not coming back to what they should be. I took a look out the downstream channels and saw a lot of corrections and uncorrectable(s). This screen shot was taken with a modem uptime of about 20 minutes.   Spoke with Xfinity rep and basically said everything is good on their end and to contact manufacturer.  If anyone could provide any suggestions I am all ears.

S33 Upload Speed Issue

Like most I’m on Xfinity with my own S33 modem. I updated my service to an 800Mbps/100Mbps plan and haven’t been able to get anywhere higher than 11.8Mbps uploads on the Xfinity speedtest site. A tech came out and ran a new line today and we removed a splitter that was no longer needed and he said the signal levels were much improved. The only thing I’ve seen improve so far is the number of correctable and uncorrectable errors on channel 1 have gone away with the new line. Otherwise, the power levels on the upstream connection actually seem to have dropped (maybe that’s ok) from 47.5 dBmV to 43.0 dBmV. I’m still not getting any higher than the 11.8Mbps even though I’d expect to at least hit 20Mbps if they still haven’t opened up support to 100Mbps to the S33.Here are the levels from the modem status page after the new line was installed (and splitter removed). Does anything stand out as a problem? Xfinity support replied that they’re showing downstream SNR is at 44.5 and your upstream

SB8200 Two Separate Subnets

I was hoping to setup 2 routers on a newly purchased SB8200 modem. I had one router configured as 192.168.1.0/24 and the other as 192.168.2.0/24I have been Googling but am stumped. I was hoping to have 2 isolated networks - if it’s possible.If there’s a KB floating around, or if anyone has some guidance, I would sure appreciate it any help.Thank you, and my apologies for a rookie question.

Need modem for Spectrum ISP that can connect to (NON-wifi) Cisco router - SB6190

Good day, I recently had some connectivity issues with my Spectrum service.  I had been using an Arris modem provided by Spectrum for years, but part of resolving their issues, they replaced my old Arris modem with a super duper Hitron modem.Speed with Hitron modem is improved, but it unfortunately connects only to a single PC in my home, it WILL NOT CONNECT to my Cisco RV325 Small Business Router.  Previously, the old Arris “just worked” as far as getting an IP from Spectrum to allow all systems on my network to have internet access.  However Spectrum is unable to provide any support other than “it works on our side”, and tell me that I need to contact Cisco.I see on the Spectrum site that the Arris SB6190 is compatible with their service, and also see that I can purchase one from Best Buy.  Will the Arris SB6190 be able to connect to my Cisco Router?I will run to Best Buy and pick one up!!

New S33v2 Already in use and unable to activate the modem

I bought a new, factory sealed S33v2 but Xfinity (Comcast) was unable to provision it as the MAC address was already in use. How can that be?

S33 Replacement not working - Arris won't refund

So I had a S33 for a few months, then it stopped working. Arris sent a replacement. The new one won’t connect at all. I worked with Xfinity for over an hour trying to get it connected and they told me there was a Docsis error on the modem. So I’m using a rented Xfinity modem now and it works perfectly.I called Arris about just sending theirs back for a refund but I was told that was impossible since it was a replacement. They want to go through troubleshooting before they’ll even offer any recourse.I am done with Arris I think. After going through two bad modems I just want a refund. Will they offer a refund if I go through troubleshooting with them and it still doesn’t work or will they just send an endless stream of replacements until my warranty runs out?

S 33 won't regrister with Xfinity

Tried to activate an Arris S 33 with Xfinity, Xfinity said that my old 6190 modem is too slow for my internet speed, and I needed to upgrade.  My modem won’t activate, I have tried many times using the app, the light flashes green, and after 11 minutes the app says it couldn’t find the modem.  I hooked up a computer to the modem and on the status page is says security failed, and Docsis network access enabled, Status Denied.  Today, Xfinity came out to check my lines, I had a weak signal, they replaced lines and connectors and when the tech was done, I had a great connection.  He tried many times to activate the modem and couldn’t.  He finally called his tech people.  The tech lady tried to activate the modem on her side and said that it showed active, but wasn’t connected.  She said that she couldn’t see an IP address for this modem, and because of that, couldn’t activate the modem.  She told me to contact Arris and see if anyone has had this problem and how to fix this problem.  This

Arris S33v2 Xfinity Issue and modem rebooting on its own.

I posted on here a while back about my S33v2 randomly rebooting several times a day. I have been chatting with some Xfinity agents on Reddit and they lead me to an interesting discovery. While the S33 is on the list of recommended devices, the S33v2 is merely listed as compatible and not recommended. According to the internet, the v2 was released in mid-2021. Despite a different chipset and firmware, there is little difference between the two. Why has Xfinity not certified the v2 version in the last 2.5 years when it is clearly the newer product and probably the only one you can actually buy for the last 2.5 years?My issue is clearly something to do with this modem as I had been using Xfinity’s XB8-T modem for the last month and had zero issues.Is there anything I can do about this except just keep using the XB8-T and eating the $15 bucks a month?If they havent certified the S33v2 in 2.5 years, is there a decent chance they will ever do it?Thanks

My sb8200 has 2 internet ports. The #1 connects laptop to modem. It flashes orange. 2 connects my router to the modem. It flashes green. Shouldn’t both be flashing green?

Can't sign into modem

I have been trying to sign into my router and the username and password listed on the bottom of it does not work. I also can’t find it online. On the bottom it says it’s a Technicolor CVA4004TCH1. It’s not even listed on the Technicolor website. The only search results I get for “technicolor cva4004” appear to be either fake malicious websites or a website called cox that doesn’t tell me anything relevant. When I go to the address that’s listed right above the username and password, it brings up a page that says technicolor DOCSIS 3.1 Cable Modem, but again, the login does not work. I’ve searched the internet for an hour now and have found no solution.
