ARRIS S33 Cable Modem - every day at 17:00 hrs the date is set to 12/31/1969

I am currently using COX for internet at 1 gig download and 100 m upload. Every day in the event log the date is set to 12/31/1969. As soon as it does this I lose internet connection until several minutes later the correct time and date are set.

S33 power cord

This is a very basic question. I had stored my S33 when moving and the power cord that was near it (however not sure which power cord is correct), is branded as APD model # W8-18R12FU (asian power devices). Was this the one that came with the unit?

Updating S33 (HW v1.0) firmware for a purchased modem?

How do ensure I have the latest firmware running on S33 hardware v1.0? I purchased my modem and I use it with RCN/Astound Broadband as my ISP. I don’t see an option to update firmware in the web portal. I show “TB01.01.001.13_082420_192.S3” as the firmware version. Please advise.

S33v2 intermittent internet outages

Recently installed, replacing older cable modem. Xfinity service guy was out, said all is good on their end, but we needed a new cable modem since we were having tv issues. Installed the S33v2. We are now having intermittent internet outages, multiple times a day. Lasts only for some minutes. I note the power level on upstream bonded channels (5 of them) is 58.8 on 4, 52.8 on 1. Your docs say it should be no more than 51. Is that 51 a true limit, and could that account for intermittent internet outages? Thanks Don

Arris S33 Port Grounding

Does the Arris S33 Cable modem have a RJ45 Port grounding? I see the metal on the outer edges of the RJ45 port but I just want to make sure? The reason why I ask this question is because of this picture I am acting to this thread. I have cat8 S/FTP Cables and I am worried about the ( ANTENNA EFFECT). Basically the one question I have is if there is metal on the edges of the RJ45 Port does that indicate Port grounding? Thank you in advance for your help & time! have a wonderful day!

is there a way to test my modem's speed?

so i am having fluctuating internet speeds from 300-500mbps, my spectrum plan is 1gbps, the technician told me he ran a speed test from the outside line and was getting close to 1gbps and he ran from my router to his device and was getting around 700mbps, the only thing he couldn’t test was my S33 Modem, i also ran a local in house speed test from my NAS which connects to my switch then hits my router then to my pc and i get 890mbps download and close to 900mbps upload, the only thing i cannot test locally is my s33 modem, is there anyway to run an inhouse test? i also reset the modem to factory settings and the first couple of minutes i had a good speed test of 800+mbps download but after i ran it a second time it went down to 300mbps once again, Note: all these were wired tests, directly connected. any help would be greatly appreciated!

S33 Firmware Update - Change Time?

I normally work on-line beginning at 3:30 a.m. However, my Arris S33 modem goes through its automatic firmware update between 4:00 and 5:00 a.m., disrupting my Internet connection. Can I change the time of day that these updates occur?

5G not working

My 5G connection is not working on my S33v2. I’ve tried rebooting the modem. I’ve tried using multiple routers. I’ve called xfinity and they say everything is normal on their end. I pay for 1G internet and currently am getting 10-15MB internet through the 2.4G channel.

Internet connect drops every day at 1AM

I have an Arris S33 modem which I activated on May 27, which replaced a Comcast Xfinity supplied gateway. Since activation, I’ve discovered my internet connection drops every day at around 1AM and connection returns within 5 minutes. Never longer than that. The schedule is the same every day and has not changed. It is not just Wi-Fi but also when connected via ethernet on my desktop computer. I have an Amplifi Alien mesh router which is up-to-date firmware wise but I've already ruled it out as the culprit. During my weeks of troubleshooting, I've been on my desktop computer directly connected to the modem as well. When I lose connection at 1:00 AM, my Xfinity app says it is "Offline". My Alien app shows device is not connected to the internet and "No Internet Connection" is displayed on it's screen. Looking for some help in further troubleshooting this issue. Where should I be looking especially when the connection drops at same time every day? I’m working simultaneously with Comcast o

No internet (s33 + aruba 315)

Howdy, just moved to a new location and we're trying to get things running. We purchased an s33 for use with xfinity and a friend gave us an aruba 315 for use instead of a router. This will eventually change to being modem > switch > cable run to 2 rooms > AP, but for now we're just trying to get wireless working. The modem is registered/activated and the blue light is constant. We've power cycled the modem and AP, swapped cables, etc but still no internet. Hardwiring from modem to a laptop doesn't give a connection either. What next steps should we be taking here? Comcast has already been out and checked the coax and it was "good to go" but I'm less inclined to take their word.

S33 reboots itself

My signals are good, event log from yesterday attached. It did it again this morning. I can’t tell if it’s an ISP initiated reboot but two mornings in a row seems unlikely. Also, is this thing supposed to run warm? I’m about ready to ship it back.

Can't access 192.168.100.1

Ok, this is just pointless. I’m trying to diagnose random internet drops. Xfinity says it’s my modem. I’d like to access the logs, but the only way to do that is to hook my computer directly to the modem AND REBOOT IT! Which clears the logs. Arris has a handy dandy app, but it doesn’t have any actual functionality and can’t access anything? So other than unhooking my wi-fi router and bringing down my entire home network to hook a computer directly to the modem and wait hours for a another network issue, how am I supposed to access the logs? Arris could fix this multiple ways. Let me change what the modem is connected to without a reboot. Make an actually useful app. Allow the option to automatically send logs.

Wrong ISP

My modem, S33, says it’s connected to COX when my ISP is Xfinity. Does this matter? If so, how do I change it? FYI my internet works perfectly fine. Didn’t know if this was just a minor error.

Facing Apple iCloud Private Relay Issue

Since replacing my Comcast Xfinity provided Modem Gateway with an Arris S33, I have been receiving alert notifications on my iPhone that my wifi network 5Ghz is “not compatible with iCloud Private Relay”. This only happens when I’ve rebooted my iPhone. I don’t get this message at all on my Mac mini M2 or MacBook Air M1. It’s a bit confusing because when I tap “Use Other Network” it dismisses the notification and I’m still connected to my wifi network and Private Relay is on, and my internet connection appears to work fine. Has anyone else experienced this that can help explain?

I had to unplug it, it did it again a week after etc. it’s plugged into a cyber power backup battery. Any ideas on what could be going on here? TIA also should I use my warranty if still valid?

SURFboard Central iOS app - I can't log in

I’m able to login to the admin portal of my S33 using a browser but having trouble using SURFboard Central app. On the WELCOME page, I’ve entered my Email ID, agreed to terms and conditions, and when I tap SIGN IN under “Already Registered?”, I’m brought back to the first WELCOME page that asks, “Please enter your email address to access your account”. I enter my Email ID and tap “SIGN IN” and it takes me to the WELCOME page again to create my account or sign in if already registered. I’m on an endless loop.

Interpreting S33 Event Log

The event log generated by my S33 cable modem contains detailed information about the modem’s operation and errors encountered during its normal operation. However, definitions explaining the contents of the event log are astonishingly not included in the user’s manual. Google searches had me going in circles. Does anyone know where can I find the meanings of the various event levels and error messages? What twisted and deluded logic did Arris use to decide that excluding such critical information was a good idea? What's the point of providing this information, yet making the definitions difficult to find?
