S33v3 will not activate

xfinity could not activate the modem. they could see the modem and run tests but could not activate it. Xfinity documents the modem as compatible.The modem’s front light was solid blue. The modem was very hot.My old modem still works so I don’t believe there is a problem with cables.Shall I exchange it? It was purchased from amazon.

The power went out and when the modem came back on it only flashes green. I pulled the power out for 30 seconds but no change. I tried doing the reset button while I was flashing and still only flashing green. Not sure what else I can do?

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

Arris Surboard S33v2 making constant noise after one year?

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. I think I am also noticing buffering in videos when I was not before. What can I do while I’m still within the 2 year warranty?

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

Hello: I did my best to set up my new modem, and it works, kinda’.However, while I set passwords for WiFi 2.4 GHz and 5.0 GHz, they are not accepted. 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

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?

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?

WayneThe Many

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.
