Fast to slow in a minute

My S33 starts out getting 550mbps then drops to 30mbps within 60 seconds.  Switched to a hard line to no effect.  Repeatable issue.

Can a PoE Splitter fix the issue with S33 only allowing one connection

Hello,I want my PC to be connected directly to the S33 with the 2.5GB port, while my router mesh system is connected to the 1 GB port.  Based on testing and what I read this is not possible as the S33 will only cater to one connection for because of IP addresses. My question is if I buy say a Cerio POE-PD04S+ PoE Splitter plugged into the 2.5GB port will I be able to successfully connect both my PC and Mesh router to the POE? Appreciate the tips in advance, currently I just have the Router plugged into the 2.5GB port while the PC is connected to the router’s 1GB port. I could possibly test having the router connected to the 2.5GB using its 1GB port then plugging the PC to the router’s 2.5GB but assuming that wouldn't work.

SB6183 & SB6190 modems - Slow internet speed

I’ve been using a SB6183 for a number of years now, and yesterday I was told by Infinity techie that my incoming speed was GREAT (better then 1000mbps), but it was my modem that slowed it down to 45-55 mbps. How is this happening when the specs on the modem says it does up to 686 mbps?So lets say i need a new modem,...maybe the follow on product SB6190. Looking thru various sites does NOT give me a lot of confidence this modem is any good?? Can these relatively simply units be that hi-rate faulty? Then I saw on a Comcast/Infinity community forum where Comcast themselves were defeating some installations of hi-speed modems,...some of these from ARRIS ??What is this world coming to,...a whole lot of mis-information. I’m just a plain old 81 year old model railroader who wants to surf the forums, and is NOT a computer-head to figure out basic stuff   !All I need according to those more informed is a speed of 100-300 mbps to cut out this ‘firefox not responding’, and msnbc choppy reception

S34 - Timeline for release of this modem

On both xFinity’s website cable modems section and CableLabs approved modems list is the S34. CableLabs shows a CQ date of 2024. Does Arris have a timeline for release of this modem? If so, I’d prefer to stay with the brand instead of upgrade to a competitor.

SB6190 works with direct connection but not with router

I just bought this modem (SB6190) and am already at my wit’s end trying to get it to work with my router! I was able to activate the modem myself via the Xfinity app no problem, and it works just fine when I connect the modem directly to my computer via LAN.HOWEVER, the instant I try to connect the modem to my router, it simply will not work! My router’s light indicates that it isn’t connected to the internet, and when I try to configure the router via LAN connection, it says it can’t find its assigned IP address. I’ve power cycled both the modem and the router several times in the correct order (i.e., power both off, power modem on, wait until connected to Xfinity, power router on), but the problem persists.To make sure this was a modem problem and not a router problem, I re-activated my Xfinity Gateway and plugged it into my router into that. And hey, what do you know—everything worked flawlessly!So, can someone PLEASE help me figure out how to get this thing to work before I go insa

No internet on SB8200 connecting with router

You know that little world globe that's normally position down in the right-hand corner of your screen. Right now it's not a globe but an icon of a computer screen instead.When I hover over that icon, I get that the 5Ghz Linksys routed is connected.   But when I open up that icon, where you would normally hit "connect" it say no internet connection. Thats my problem.  I just changed out an SB6141 and all connections worked.  I added this new SB8200, and I’ve now got no internet to connect to my Linksys WBT3200ACM router.But my cell phone, tablet, and laptop all connect to the router with a strong signal.  Its just this desktop HP that no longer works right.  Destops 2years old.I did get the correct connection momentarily when unplugging the router and resetting but that lasted but a few minutes

Arris Surfboard SB6190 - Laptop is not connecting with internet

My laptop is showing no Internet connection even though all my other devices are on line. My Internet provider tested all the equipment and says they are working properly. They suggested that my modem probably needs a wifi driver update. What should I do?

Cable Modem which supports Euro Docsis 3.1

I am looking for a cable modem supporting EuroDocsis 3.1 , min 1 Lan port and preferably (but not required) 1 fon port. It should not have an integrated router. Are there modems like that here? I am just unsure if “Docsis 3.1 ……… Supporting all major Cable Providers” means globally or US only.

Sb6190 and linksys e5400 no internet

I just got the Arris Surfboard sb 6190 and now it's not working with my Linksys e5400 wireless router. I have a Google pixel 8, and it keeps saying that I need to sign in to the wireless network, but from there it takes me to spectrum for activation even though I thought it was done through the app.  I can see I'm getting Internet thru the modem, but nothing thru the wireless router.  Any help appreciated.  Thanks all!!

SB8200 Xfinity only 1 upstream locked channel

My SB8200 and SB6183 only get one upstream locked channel at 35.6Mhz. I see many posters have 4 locked upstream channels. How have other folks resolved this issue? Channel ID Lock Status US Channel Type Frequency Width Power 4 Locked SC-QAM 35600000 Hz 6400000 38.3 dBmV  Also the SB8200 on power-cycle takes 18 minutes to lock the upstream channel. The upstream channel tests 16.4, 22.8, 29.2 at different send power levels, till it reaches 35.6 and acquires lock. Has anybody else faced this problem.Power cycle timestamps are mm:ss.01:00: WebUI comes up in 192.168.100.1 01:25: Receive LED steady green, send LED flashing green. 01:25: Downstream channel locked 49.5Mhz, 13 dBmV, 44dB SNR. 01:25: Upstream parameters acquired. 01:26: Upstream channel 22.8Mhz, 48.8 dBmV. 05:25: Upstream power oscillates like th 59, 49, 38, 28, 61, 51, 46, 41, 31, 64 dBmV. 12:11: Upstream channel 29.2Mhz 14:08: Upstream

New SB8200 uplink led blinking (not syncing)

I bought a new SB8200 upgrading from an SB6183. When I connect to the same location with the same coax cable as the old modem, the receive.led is green steady, but the send led is green flashing. Per the manual, it means the modem is scanning for an upstream (send) channel connection. I have talked to Xfinity and they cannot remote troubleshoot because the modem appears offline. When I put back the SB6183 I get steady green receive and send leds that then turn up Internet in 5-15 seconds. So my problem is the flashing send led for 5-10 minutes without syncing. Has anybody else faced this problem with SB8200. Thanks.

Why is my SB8200 blue receive light always on? Internet still works.

After recycling powered to my SB8200, the blue receive light is always on. Thankfully my internet works fine and signal is getting from the modem to the router and the speed checks are normal.  Xfinity is my service provider with the 900mbps plan and there are not outages updates or issues for me or my area. I have tried recycling power and have also done a factory reset. Still no change.

Arris Surfboard S33 not working

Arris Surfboard(s) not workingBeen using an Arris Surfboard S33 for a few months now and have had no issues until today.    Came home from work and suddenly it seems like it’s bricked or something.    All three LED (green, blue, amber) indicator lights are lit up, leaving a yellow-ish solid light that never changes or blinks. It’s completely unresponsive and I am unable to connect to the internet.    The lower Ethernet port on the back has lights on while the top one does not. Plugging the Ethernet to the router into either one does nothing and neither does hardwiring my PC into either one.    I know the pics shows the coax unplugged, but that was just to capture the lights easier.  Using a pin to reset the modem does nothing. Tried for 10/20/30sec and no dice.  Title is plural because I went out and bought a second one thinking the original one was just faulty, but upon giving it power, it does the same exact thing.    I never plugged the second one into coax so I don’t think it could

Dropped connection and too hot to touch the modem SB8200

Last September my old modem stopped working so I purchased a Arris SB8200. For the last few months we have experienced numerous dropped connections. It is now being dropped even a few times a day.At first the lower earth symbol would start blinking. Now it stays on like it should but is getting almost to hot to touch. I did a search for cause and this model was the first thing to pop up. Overheating was a large issue.We purchased the modem from Best Buy on 09-22-23. According to this web site there is a two year limited warranty.What can be done to get this modem replaced or fixed?We look forward to hearing back.ThanksRob Garrison
