Who do you believe (Typical xFinity song and dance)

Some minimal background for context, I work 3rd shift weekend providing customer support for an operating system vendor. This means that I get to (try to) live through any ISP changes that xFinity/Comcast throws on their victims. About a month ago some change was made and my SB8200 that had been working fine (with a functioning DOCSIS 3.1 indication), so to speak. Performance went to heck and none of the troubleshooting suggestions helped (rebooted several times, factory reset, etc). At the time the modem log had an entry about a failed firmware download and most of the channels had logged both correctable and non-correctable errors. It should have been a hint that the normal address for the SB8200 config pages didn’t respond but 192.168.0.1 connected.Enter Comcast… After the usual foolishness the agent finally tried to ‘look at’ the modem using their tools and that was a total failure. From my view the modem was working but, honestly, wasn’t performing as well as internet over

Firmware release name/ number for S33

I am looking to find out what the latest release and version is for my S33. I would like to know if the one I purchased is up to date. I understand because I own it I cant update it from you nor will my ISP. And dont tell me they auto update it, because they dont.That isn’t the question. I want to know it for my knowledge, and if you wont tell me, why wont you?So, when we think it might be too old we can replace it.

SB6190 Signal Upload Levels on RFoG Fiber to House

With 21 days active up time, I have approx 300 correctables and 21000 uncorrectables per channel on downstream side. Is this what is to be expected with an RFoG fiber type setup or are these happening specifically from my modem to the RFoG adapter on back of house?Also my upload power levels are between 35 and 36.5. Channels 1 and 2 are channel ID 75 and 76 respectively using 2560 KSym/s. Channels 3 and 4 are using channel ID 74 and 73 respectively using 5120 KSym/s. I read that power upload should be closer to 51 and not the approx 35 I have.This is the setup:cablemodem and after that is the injector sending power to the RFoG coax/fiber device on side of house using the coax line. The coax line is direct run with no splitters and all connections are factory spliced provided connections and good splice connections done by provider. The RFoG device is grounded outside and outlet grounded inside.

I have an Arris Wifi Router Modem combo, Model Number DG3450. My 2.5Ghz and 5Ghz wifi connections have the same Name and Password all of a sudden and I need them to be different so I can connect to different devices. When I try to change the name and Password of the 2.5 and 5 ghz Wifi network it gives me an access denied yet I am logged into my router, it just gives me the access denied when i try editing the name or password of ether? How would I fix this, anything helps?

changing username and password for SB6190

I was told by my internet provider that I should change my username and password on my Arris SB6190 modem. There were some concerns that our usage is unusual and perhaps we’d been hacked. They said it wasn’t their equipment.

S33 Not connecting to the internet with a direct ethernet wired connection

Hello, I have an S33 modem with Spectrum internet. The spectrum tech installed the modem and it has been hooked up to a wireless router and working fine with all wi-fi connections. After the install I connected the modem directly to a network switch and the wireless router still works fine. However I have connected an NVR home security system to the switch that requires direct ethernet and it wont connect. I called the security camera support and they are telling me that the direct line is IPV6 and it needs to be IPV4 to work. I am also experiencing no internet connection my wired Samsung smart tvs. Is there an easy fix?

Led light turned off on S33

Years ago, when I set up my S33, I turned the LED off. Now I want it back on. I was mistaken that a hard reset would do that. I'm kind of surprised that it didn't.I downloaded and installed the web manager. No joy there because the app can't find the modem (?!?).So... What's the trick?

In order to get a service from Xfinity I would need el Network Namen and Pasword of my modem. Given that the modem is Motorotola I asked them about that. Motorola sent me an email telling:“Based on the MAC address provided, the device appears to be an Arris modem. The older Motorola modems, the Surfboards, were manufactured by them. Please reach out to Arris's customer support for further assistance with addressing the issue you're experiencing with your modem: https://arris.my.salesforce-sites.com/consumers/ConsumerProductSupport.” The information printed on the bottom label:of the modem is: SURFboard Model: SB6121Thank you.FCI:001 Thank you.

SB6190 needs to be rebooted daily

My SB6190, connected to Comcast, has worked well for the past couple of years. There were the occasional Comcast outages, of course, but now I am unsure if the problem is Comcast or the modem, since the problem is always cleared up by power cycling the modem. This started about 2 weeks ago, and occurs daily, sometimes twice a day. Below is the event log from today. 10:11 and 16:50 are immediately after the modem is rebooted. Any thoughts on whether I have a hardware or internet provider issue? Thanks in advance!!

modem disconnecting every few seconds from new internet connection at new place

Frustrated is not the word! SB6183 Arris should have more customer support than this. Signal won’t hold- drops internet connect every 5-6 seconds and reconnects every 10 seconds. New place, new internet connection, new company. Signal good from pole to house. All wires have been checked multiple times, power cycled many times, still happening.

No internet when connecting a router in SB6183

I just got connected to xfinity internet today with my new SB6183. When I directly connect my computer to the modem, I connect to the internet just fine. When I connect the modem to my wifi router, nothing. Do I need to update any settings in the modem prior to connecting my router? Or is this just a router issue? The router was working just fine 10 min ago connected to my old modem.

Surfboard cable modem S33 D3.1 with low upload speeds-s33

I'm an Xfinity internet customer experiencing an issue with my modem's upload speed. While my download speeds are good (around 450 Mbps), the upload speed is erratic, ranging from 0.1 to 1 Gbps within a short time frame.A technician visited my house and checked the coax connections and modem performance. Although they didn't find any obvious issues, they suspected a possible hardware failure within the modem. They temporarily installed a different cable modem, and the upload speed stabilized significantly.The modem I'm currently using is an Arris model purchased in February 2021. Given the technician's suspicion and the temporary fix, I'm considering replacing the modem. However, I'm unsure if this is a common issue with Arris modems or if 3 years is the typical lifespan for such devices.I'd appreciate any advice on whether to replace the modem and what brand/model to consider. Has anyone else experienced similar upload speed fluctuations with their Arris modem?
