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?

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?

Arris just lost a long standing customer.

I have been a long time user of Arris modems. My new S33 that I have had for three months quit working today. It was very hot to the touch and I suspect it was overheating. My old Arris modem was relinked and works fine so I know it’s a modem problem. Arris refuses to repair/replace the modem because it was purchased new off of ebay. Wrapped in a box…… Never connected to the internet. Half of me understands this policy but the unwillingness to help does not. No offer of a partial credit even. I’ll be switching to a different company and will never purchase from you again. Its not about money for me. It’s the unwillingness to do absolutely anything. So here I go to look for other brands.

Arris S33 can I change password before connecting to Xfinity cable

To minimize vulnerability, can I change the admin password before I connect the cable for internet access? Or does it require xfinity activation first?

Arris S33 missing OFDMA channel

New modem, local cable company recently upgraded to DOSCIS 3.1.  My download is awesome with this modem, but the upstream is missing the OFDMA channel, which is causing my speed to not reach the max speed I’m paying for.  Had a technician come out and he noticed that my modem wasn’t connecting to that channel. He put a temp modem on (different model) and it was able to connect to the OFDMA channel.  The tech was saying I probably need a firmware upgrade, but the modem I have is one I purchased and they don’t carry those. Therefore, he isn’t sure if they can upgrade the firmware for me. Can anyone help with this or give me advise.

S33 Ports

Two ports on back. 1GPS and “up to” 2.5 GPS. The 2.5 port implies I can hook up my 1GPS service into that port since it’s “up to” 2.5. Sometimes the cable provider exceeds the speed I’ve subscribed to. I saw it a lot when I was in the 500 MB/s plan. It’d go to 600-700. So now I have the 1GBPS plan. Should I plug into the 2.5?

S33 Reporting Data Usage to Xfinity Tripled

Hi All,  I purchased and installed S33 in February. It worked well. However, for March and April, Xfinity reported that 3x-4x data usage than before (and charged for additional data). My router reported 1/4-1/3 of the data usage. So I called Xfinity to see why there is a difference in data usage being reported. Xfinity said it was because the S33 did not report data usage correctly. Does anyone know how to solve this problem? Or is this a problem with the S33?Thanks all for your help.

S33 timeouts multiple times a day

I am struggling lately with disconnects on my S33.  The cable connection coming in to the house was terminated by Cox and there are no splitters or any other devices on the line.  The connection is from the box at the street to the house to the modem.  Despite the constant issues, Cox claims it is my modem because they are able to reach it with a reset packet and if they can do that, there is absolutely nothing wrong with their service at all.  Yes, it works sometimes, but many interruptions throughout the day.  The modem is less than two years old because I replaced it last time they told me to.  I’m not convinced another modem will solve my issues.  I have the following types of log messages on the S33 Event Log: Started Unicast Maintenance Ranging - No Response received - T3 time-out; SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing; MDD message timeout;Is there any other info I can provide to help troubleshoot the issue? Thank you

Hooking Up S33 to Deco XE75 Pro

I am trying to connect a TP-Link XE75 Pro to my S33 Cable Modem. It wants to know the internet type and I contacted Xfinity and they told me that since it is not a modem provided by them, they cannot give me that information. They told me to contact Arris.

s33 no connection

We've had our s33 for about a year , love it, works great ...tonight while watching TV one of the cats ran passed it and unplugged it, plugging it back in now results in just a green flashing light and no internet, Xfinity can't see it at their end and can't provision it again, I've done a factory reset but it's made no difference. In the web interface it says that DOCSIS network access is denied and also the system date and time is set to Jan 1 1970 but I can't see any way to correct that? Everything else looks normal to me

Connect S33 to HP Printer via printer pin

I’m trying to connect a HP 3056A for wireless printing. I expected to see a WPS button on the physical device, then expected to see a button on the https://192.168.100.1/ settings page. Didn’t see that anywhere, nor Surfboard Central app. There is also an option on the HP printer for a printer pin that I’m supposed to enter on the router settings. I looked on Surfboard Central for my W121 mesh network, didn’t see anything. Can someone point me in the right direction?

S33 on Spectrum Error: SW upgrade Failed after download - SW File corruption

As the Title says, checking my event log after provisioning was complete showed SW Upgrade Failed. Is this an issue with Spectrum not pushing the correct firmware? Has anyone else experienced this?

Unable to login GUI page with default password

Brand new S33.  Installed it last night, and it wasn’t talking.  Woke up this morning, had not touched it, yet it was working fine. Proceeded to try logging in to https://192.168.100.1/Login.htmlI have carefully observed the serial number and tried to log in with the last 8 digits.  The serial number is in this format:block 1 - 4 characters, mixed letters and numbers - spaceblock 2 - 4 numbers - spaceblock 3 - 4 numbers - spaceblock 4 - 3 numbersAs such, the password I am using is the last digit of block 2, all 4 digits of block 3, and the 3 digits from block 4.  That does not work.  What am I missing here?
