issue with connecting sb6183

I have bought the arris sb6183. I noticed the box does not come with a password for it. Will I be able to access the internet with this if I connect it to wall with coaxial cable plug in power and connect Ethernet to computer and typing in the code starting with 192. or is this setup incomplete?

SB6183 isn't connecting through ethernet to my PC

My PC isn't receiving an internet connection from my surfboard modem. I talked to Xfinity and there's no issues on their side. All the lights are the colors they are supposed to be. (Green blue blue green) but I'm getting no internet through the ethernet cable. I've tried several cables as well and it hasn't helped. Everything is plugged in correctly as well. I've tried resetting the PC numerous times and the modem as well. I've tried turning my firewall off and that doesn't work either. I can't think of anything else I can possibly do. Any insight would be greatly appreciated.

Internet Modem without WiFi

I have my set-up with Arris (my old unit), Netgear WiFi 7 Router and Ooma Phone.  I need to upgrade my Internet Modem to allow for the Ooma Phone, which is hooked up to my Netgear.  Which Arris Modem would work for my set-up?

S33 - No internet on Wired Connection

I have Xfinity internet using my own S33 modem and a 6g router.  My wife has concerns about emf and wants to turn off the wireless router at night.  I am up way before her and need to have internet access as I often work from home.  I want to be able to use a hardwired connection to my home office computer while the wireless router is turned off.  I thought I could use the second (bottom) modem port, but apparently cannot.  I tried simply unplugging the router from modem and plugging the ethernet cable into that modem port, but it doesn’t work either.  What is the best way to do this?

SB8200 issue after moving - No internet

After moving to a new location (moved to an older house as opposed to being in an apartment), SB8200 can’t establish a downstream connection. Getting errors very similar (almost exact same status message) to the ones in the following post:I also am getting multiple instances of “UCD invalid or channel unusable” and “No ranging response received.” Modem has worked for 2 years and has only started failing after the move. Checked and the warranty has expired in March of this year. Any suggestions on how to fix this issue? Thanks!

our wifi is out and our provider sent is to arris for a solution - SB8200

Before I go into detail, I want to proactively thank  this community for the help you can provide us.  Thanks!!  Our Wi-Fi account is no longer available on our house system. Our WiFi provider did several tests/checks and said their signal to us was good. They referred us to Arris because we bought an Arris SB8200 modem and router which has worked fine so far. It sounds like we need help setting up a new account through your modem. I have no idea how to do that.

Compatibility of S33 and S34 while enabling VPN on the devices

I have Spectrum 400MB plan.  Can I use either S33 or S34 modems?   Particularly attaching to company VPN.  I've been told that my connection has a lot of Jitter.  Will either of these devices help that?

My wifi fails to connect to Internet Every Morning - SB8200

I have bought a new modem SB8200 and router Tp Link Archer AXE75 for few months.On Saturday October 26, 2024, my wifi stopped connecting to Internet. I followed this site instructions https://www.tp-link.com/us/support/faq/1556/. I removed the power cable and coaxial cable from SB8200 modem, then waited for 1 minutes. I turned on the SB8200 modem and waited to for it to startup. After it booted up, I plugged in the coaxial cable and my wifi stopped giving “connected without internet” and everything was fine. But this happened on Sunday the next day, I redid the steps on I took on Saturday. And today, on Monday, I just unplugged the power cable from SB8200 modem and the wifi started working. I think my router is working fine because I don't have to restart it. But I really don't know which of the two, modem or router, is at fault.I hope to get some help to pinpoint the cause and fix this problem. Thank you for time.

SB8200 Ethernet Ports LED lights are off

Just want to confirm if the unit I got has busted ethernet ports. The front indicator lights on my modem and my ISP show connection is fine. However the lights by the ethernet ports don't seem to go on except when the device is first turning on. My router is showing no connection to the modem and tried the same with laptop with different cables and got the same thing. I assume the lights on the back by the ports should go on if the ethernet port(s) are working. Is that correct? Also I'm only using one port at a time.

SB8200 bricked and unresettable

Hi,I am having an issue with the modem where all lights are solid blue but the modem is not working.There is obviously no internet. However, even when I plug in ethernet to my computer, it does not even get detected as connected. I know its not the ethernet cable or computer because I plugged the same computer with the same cable into another modem and it detected it fine.  I tried restarted it (plugging it out, leaving it 10 mins and replugging it) and it immediately goes to the solid lights, no blinks or anything else. I tried pressing in the reset button for 4-5 seconds, nothing. Then again I restarted and I tried holding reset button for 10 seconds, nothing. Then I  again restarted and tried holding reset button for 30 seconds nothing. It’s as if its stuck. Like I said it doesn’t even get detected as plugged in into my computer so I cannot even use command prompt to diagnose it. The issue seems similar to  It is still under warranty until next year and I would like to get it repair

need gateway address for s33

I can't seem to use 2 devices with this modem s33.  On second device it asks for Ip address, prefix length, then gateway address.  Xfinity says they don't have it. Does anyone know how I can get the gateway address? Or do I have to wait until Monday morning to contact arris cs.

Iam looking for a modem or a workaround to disable internet access through a CAT cable. Any suggestions?

Hi Everyone,I have a couple of years-old Netgear router and a modem supplied by Comcast. I also have a teenage son who just can’t seem to learn when enough online gaming is enough. He connects directly to the modem via a CAT cable to avoid Wi-Fi lag, which means the options in the Netgear app for shutting off access don't apply since they only control the router.Aside from physically unplugging the modem, I’m looking for a way to remotely disable his access via the CAT cable, or I’m open to getting a new modem that allows for this. Ideally, I’d like a solution that lets me control it from the comfort of my bed. It’s been a long battle, and I’m tired of trying to instill personal responsibility—I'm looking for a switch solution. Any suggestions, especially regarding managing IP addresses and router settings?

SB8200v3 won't connect.

Upgraded SB6190 to SB8200v3 at professional office. Office has static IP from Optimum. 8200 is registered with Optimum. 8200 will not connect. Keeps going thru the boot process. Put the 6190 back in service, which is not registered at this point, and it connected within 2 minutes. Recently did same upgrade at my residence, 6190 to 8200v2. Called Optimum, registered the 8200v2 and online within a few minutes.

i think my s33 modem Ethernet port is going bad and no internet

So every time my deco (old)Xe75 or (new) be63 Wi-Fi router gets rebooted for a update or If I manually reboot it from time to time. When it's done rebooting the light go red and say there's no connection so then I'll have to unplug Ethernet cable for wifi router and replug it back in until it goes green. But then there's times it will show green but my devices will say connected to WiFi but no connection. So then I'll have to unplug the ethernet cable and replug it or reset my s33 modem in order to get things working and a stable connection again. I've also changed the ethernet cables and the same thing happens so my only conclusion is that my s33 is the cause of this problem but I don't know if it's the modem itself or the ethernet port is going bad. Because I ruled out the ethernet cable and I've ruled out the Wi-Fi router because I ended up buying a new Wi-Fi mesh router and the problem persists. I haven't tried resetting the s33 because I don't really want to have to call Comcast a

Upgrading SB8200 to S33

I presently have the SB8200 modem, since 2018.  I have Xfinity, and my current plan’s level of service is Ultrafast including download speeds up to 1000 Mbps and upload speeds up to 20 Mbps.  My download speed averages above 920 Mbps.  Is there any benefit to upgrading to the S33 modem if I don’t upgrade my level of service to 2000 Mbps?  Upgrading to this speed would cost an additional $25, so would I see download speeds of 2000 Mbps if I upgraded?
