Warranty Registration Fails S33v3 modem

My new S33v3 modem works fine and is connected to Xfinity. When I try to register it with Arris for the warranty, when the online form validates the model, it tells me the serial number and model number do not match. I’ve tried entering the serial number multiple ways, same results. I verified the serial number through logging into the modem, as well as the tag on it. The registration screen tells me to call a phone number which is answered - no voice or message - then disconnects after a few seconds. If I try the online chat, it asks to check the warranty status first, which of course it fails because I am unable to register it. Any suggestions? Not feeling all warm and fuzzy at this point. Thanks.

Accessory warranty not documented on S33

This is admittedly a minor thing, but annoying. My S33 modem recently had a problem booting and connecting. Thanks to this forum, we figured out it was the power supply going bad; substituted another from an external hard drive and the modem booted and connected fine.My 2-year warranty on the modem runs until Sept. 2025, but when I contacted support about a replacement power supply, I was told that “accessories” are only covered for a year.Ok, cool. But where is that documented? The warranty card for the modem says software is covered for 90 days, and “(B) for the Product (excluding software), for a period of two (2)years from the date of purchase from ARRIS or from an authorized ARRIS reseller.”I don’t see any mention of accessories, though I do see a paragraph that says, basically, if it doesn’t have an Arris label on it, it’s not covered at all. The power supply is not Arris branded, so, technically, I guess they don’t have to cover it at all.So what incentive is there for Arris t

Arris S33 Overheating

Purchased the S33 three weeks ago, and for the past week it has disconnected at least 4 times already. Twice it happened overnight, so I wasn’t able to see what was happening. Turns out the modem overheats and shuts off. It finally turned back on after 30 mins and the light was white and eventually it turned orange after an hour. It still was not online though. Took a good 3-4 hours before it was back online.

Opening ports on S33 to allow for AT&T cell booster

Hi,I have unfortunately terrible cellular service with AT&T at my home and am evaluating options. AT&T has given me a cell booster and I am trying to connect it, and have been instructed by AT&T that I have to open the following UDP ports of the modem to allow the booster to activate: UDP / 500 IPSec port, UDP / 4500 IPSec port, Emergency Services Protocol (ESP) 50, and UDP 123 NTP port (timing synch). Initially, AT&T said my internet provider had to enable this, but I own the modem (not Xfinity, my internet provider). I seem to be unable to talk live to an ARRIS rep to resolve this. Does anyone have advice? Thank you!

Sony Bravia Google Play TV works ocassionally and trying to figure why

I have a Sony Bravia Google Play TV. My service provider is Comcast and I connect to Xfinity TV program on a HDI port and Google Play is configured for the port called Channel . I began having service interruption issues on my Sony Bravia Google Play about 1 month now. The Google Play App would just hang and not load at all while in the same instance the NetFlix app would load wihout issues indicating that this is NOT a network issue on my network. The Netflix APP has its own icon and loaded without issues and have no issues with Xfinity programming loading That tells me that my TV is working ok, no issues with the sound or picture. Ive began getting messages from SurfBoard and Fing suggesting that services have been handed off. The XFINITY Remote controls the volume when ocassionally my Sony Bravia Google Play TV works which suggests there may be some crossfunctioning.

S33v2 light solid amber, blink of bluegreen then back to solid amber. No connection to any device but internet shows connected. Power cycled the provider and Arris devices, did the paperclip reset on the Arris device and checked the Ethernet and coax connections and found no problems with those. No change, any ideas??

connected without internet S33 modem

I've unplugged every cable, replugged, waited 5 minutes while everything was unplugged, waited 5 minutes after modem had solid light before powering the router, attempted powering both router and modem at the same time, tried timing them to be on at the same time, done a soft reset, and my modem still won't connect to wifi. Its done this before multiple times, but till now ive been able to resolve it and see it finally connect, but this time it will not. My asus router isn't old and it says theres a problem at the modem. My internet is fine. This only happens if the power goes out and it tries to reset.

Seeking Primer Material Xfinity -> SB 33v2 -> TPLink Router -> LAN

I’m replacing my Motorola MG7500 with a SB33v2 which will service my TPLink Archer router. I think I’ve established service to Xfinity, but can’t seem to raise the router in any configuration -- my LAN connection shows a router through Xfinity which makes me believe the router on my side is being circumvented.I am getting traffic from the internet back to my laptop in the below configurations:cable → modem→ router→ switch->laptopcable → modem → router→ laptop.Do I need to reset anything on the modem proper?Is there some guidance on troubleshooting?Is there an intermediate step available to connect to router directly? Thank you for any support you can offer. Sincerely,CW

S33v2 solid white light upon powering, no connection, reset fails, buzzing moise

I’ve had this S33v2 device in place with eero 6+ mesh devices and Xfinity ISP since Aug of 2023…it worked well until 2 days ago. The WiFi dropped, I assumed it to be a temporary Xfinity outage. After several hours I checked the modem and it had a solid while (greenish) light, normally its blue. The device was making a high pitched buzzing noise that I hadn’t previously heard. I disconnected both the power and coax, waited and reconnected…the light immediately turned solid white upon connecting power. I attempted to reset the device via the recessed reset button on the bottom of the device. I followed the instructions in the user manual holding the reset button for over 7 seconds, the light never changed from solid white. I’ve attempted several more times, holding the reset for up to a full minute, same result, the light never changes from solid white. Disconnecting the coax and connecting only power, the light goes immediately solid white. To rule out faulty coax, Ii swapped the cable

Hello, I purchased my Arris Surboard S33v2 from the ARRIS Amazon store on Jun 20, 2023, and I noticed it has been making a constant sounds lately when it was silent a month ago.

S34 - Unable to activate the modem with COX

Well after talking to Cox on the phone and in the store, they can’t activate my new S34 modem. This company really needs to stop advertising that it is compatible, because in Las Vegas, it is not. I hope Amazon will take it back, if not I wasted 200 bucks for nothing.

WiFi for SurfBoard S33 Docsis 3.1 cable modem

To link TV (Roku) and other “peripherals, it can only be done with the login data for the Web Manager. I have no idea what I may have done to cause this, but would be most grateful for help in correcting the issue. Thanks, Hans L
