SB8200 downstream connectivity light is green instead of blue

The modem is only a few months old and since a week I have an issue with it.I use comcast/xfinity and the downstream connectivity light has always been blue and the upstream has been green because of the slow speed of 40mbps.My download speed has always been about the same which is 900 mbps. Since the downstream connectivity light has turned green (last week) my download speed has not changed it’s still about 900 mbps and more.The only way I can have back the blue light to come back it’s by recycling the power or resetting the modem but the blue light will not last. During the day or next day it will turn green again even though the speed is still 900 mbpsAnyone has any idea why this is happening? Thank you

S33 power on Failure

S33 modem stopped providing internet service. Front panel LED is flashing green at Avery high rate for speed. Tried power off for multiple minutes. Tried resetting and reboot procedures. Same LED high flash rate (essentially a flicked). Tried direct computer network connection to access the modem default IP address, no response from the S33 unit. Any other options to get this unit working? Was purchased 3/31/23 and is still under warranty. Not sure how to make replacement claim if the S33 is truly dead.

power on failure in SB8200

Dead SB8200. It's been barely 6 months since I purchased this modem and it's completely dead. I have a universal adaptor to make sure it wasn't the power cord. This thing is dead to the world. Nothing I can do to fix this. It's still under warranty, but I can't seem to get in touch with anyone to find out what I need to do with a piece of junk.

SB8200 speed issue with Cox Cable

Hi, my SB8200 is about 3 years old. My ISP is supplying 500 mbps but I’m barely getting 200. Cox’s answer is that my modem is outdated and should be replaced. They will basically not do anything to help. I’m no expert and I realize things get outdated, but I don’t think that’s the case. Looking for opinions, some advice. Should I replace my modem?

Steering to satellite - SB8200

Short and to the point. I have a surfboard sb8200 and 2 mesh w21's. Only 3 days old from Amazon. I have 4 devices way passed the satellite and there all 2.4 only and their only on the main router. I have a camera off a ways also and it's the only one on the satellite. If I go outside with my Galaxy watch it goes on the satellite. The main says there are 4 devices with poor signals, but still work, and they won't go on the satellite. My main has 15 devices and my satellite has 1 and my watch sometimes. I've read lots of ideas from people that think their correct. It's crazy arris won't help anyone, they just have self help. I'm going to wait until 1 month when the warrenty is about to expire and return it and keep getting a new one until I get help. 👍

S33 modem - Xfinity (AGAIN) - csn i get more than 275mbps?

I have read the other comments, and it seems like this may be an Xfinity throttling thing! But I pay for 800 MBPS - and get less than 300? Is there anything I can do on my end??

Previous to last night and now this morning; the WiFi was working perfectly but now instead of having the green and blue lights lit, it’s just all green with the last green light blinking.

activating s33 on cox

Just got the S33. Am a little confused about the activation sequence. using connectivity on my old linksys modem, should I do the activation, and then hook up the s33? Concerned about whether i will have connectivity by installing the s33 first to do the activation.

S33 white (but pale green) status light and high pitched noise

After 3-4 months of clean operation, my S33v2 became unresponsive today with a white/pale green status light on the front, and a persistent high pitched noise. I don't suspect any Comcast issues. I unplugged and replugged it into power and the white/pale green light and noise immediately returned upon plugging in (no boot up light flashing). This was repeatable including after leaving unplugged for several minutes. While plugged in I tried to factory reset using the button on the bottom. Even after holding the button for the requisite time period and beyond, there was no change. Finally after another power cycle, I'm getting a long amber status light followed by a short white/pale green and short off, then back thru the same color cycle. The high pitch noise is somewhat more erratic during this light cycling. All the while it spits out no Internet. I'm assuming this is a warranty replacement scenario. If you agree, how do I get that going?
