Arris SB8200 - No lights except blue D/L light…?

I bought this modem yesterday and all lights were on. Today, I only have the 2nd blue light on (which tells me that I’m receiving ok) but NO other lights are on. I’ve rebooted, but it stays the same.I have a nest router attached that works fine. I also attach a switch from the nest, with a cable to my TV - which also works fine and has wired internet access.where did my lights go??? Thanks / Dan

SB8200 randomly loses internet (RCN)

I have RCN internet and a few times a day my internet is dropping out for about a minute or two. When it’s working everything is fine (no speed issues or anything). It’s the random drops that are the problem.At a glance it looks like my upstream power levels are low and I’m getting some errors in the system log that I don’t fully understand (Commanded Power in Excess of 6 dB Below….). RCN’s merlin page also shows micro reflections as red and yellow with values of -17.101 DB (red), -19.522 DB (yellow), -17.845 DB (red).

arris model SB 8200

I unplugged the modem & router & internet cable and moved it all to a different location in the house.But the internet plug in the wall must not be hooked up, so I moved it all back to where it all wasbefore. Does the modem need to be reset ?

Downstream led Light Flashing (SB8200)

For seemingly no reason my SB8200’s DS light started flashing. There are no reported outages in my area, no cables have been moved, shifted or otherwise touched. I spoke with my ISP and they advised that my modem was not able to be detected. Any suggestions ?

Newer model of same exact modem in SB6190

I went to upgrade my modem and bought a brand new Arris Surfbord DOCSIS SB 6190 to replace my old modem only to discover when I got home that I had bought the exact one again-same exact product with same model number. I know this is a dumb question but am I to assume that because what I just bought at Walmart is new that it’s components inside WILL in fact be an upgrade since it’s a new one? I mean when you replace a modem you want the latest technology and components.

SB8200 - Not responding to 192.168.100.1

My laptop is directly connected to an SB8200 that is up and running on my ISP(Cox). I can access the modem via cell phone app, but I cannot access via PC. When I browse to 192.168.100.1, there is no response. I can browse the internet, so the modem is active and working. The phone app does not provide access to settings (bridge mode). The IPCONFIG (commandline) lists a gateway IP that does not respond. I’ve tried a lot of other typical modem IPs - nothing enables access to sign into the modem. We have tried numerous ways to sign in, so please do not suggest the methods described in the manual - BEEN THERE - DONE THAT - IT DOESN’T WORK.

S33 Loses all conectivity

I have been having problems with Xfinity service? I was finding that I would lose all internet connection for 24-36 hours at a time. Ihad Xfinity out and they stated my service was fine and eventually told my my modem was obsolete. I purchased a S33 at that time and all was good. Now three times in the last week I have lost access. It is both WIFI and my hard wired computer. I have attempted to restart the S33 and my router and this does not work. I switch to my hotspot and do what I need to do. I will come home from work and presto wifi is working again without me doing anything. While on support with Xfinity I bypassed my router and plugged my computer directly into the router with no success. They are telling me it is my hardware (router) since they can see it and state it is online. Thoughts?

S33 Modem Rebooting

Moden is less than 2 months old, I had no problems until a few days ago and now just looking at my event log there's more than 150 (Yes, 150) disconnects since the 10th of november, 50 reboots daily. On the 12th it went from 5am-7pm without reboots according to my log (I didn't do anything) and then it went back to rebooting. Already checked the coax cable, manually rebooted the modem, reset the modem, changed power outlets (router on the same power strip doesn't reboot either) and I also left it on without the coax cable and it still rebooted after 30 minutes (I don't know if that's on purpose). I can see the LED change from solid blue -> solid orange -> blinking green -> solid blue over and over again every few minutes (haven't had a solid hour today without rebooting). It doesn't ever turn fully off. Downstream Bonded Channels Channel ID Lock Status Modulation Frequency Power SNR/MER Corrected Uncorrectables 37 Locked QAM256 189000000 Hz 2 dBmV 43

S33 Modem/Router (not WiFi)

Is the S33 a modem/router combo or just modem? I’m not talking about WiFi, I just need to be able to physically connect multiple devices to the LAN interface using a switch and want to make sure it hands out DHCP IP addresses. From what I’ve found the default IP is 192.168.100.1 so it does do some routing but want to make sure I can connect multiple devices on the inside.
