Intermittent internet connection on S33

Hello! I have an Arris S33 that I unfortunately trying to use with Cox out here in the midwest. Yes, their name is “Cox,” that is not a joke. I have the Gigablast plan, which is a dumb name for a poor product. Roughly 3 to 4 times a day the connection drops. I have swapped cable modems, cables and verified that the network is good. Cox will charge me to come out and inspect, so I want to make sure that I can point to a connection issue on their end. Here is the status page during the most recent outage.Startup ProcedureProcedure Status CommentAcquire Downstream Channel 759000000 Hz LockedConnectivity State OK OperationalBoot State OK OperationalConfiguration File OK Security Enabled BPI+DOCSIS Network Access Enabled Allowed Downstream Bonded ChannelsChannel ID Lock Status Modulation Frequency Power SNR/MER Corrected Uncorrectables5 Locked QAM256 759000000 Hz 1 dBmV 43 dB 0 01 Locked QAM256 735000000 Hz 1 dBmV 43 dB 0 02 Locked QAM256 741000000 Hz 1 dBmV 43 dB 0 03 Locked QAM256 7470

modem s34 issue not prompting to reset admin password

New S34 and I performed a factory reset but the Android app never promoted me to change password or have an option to do so. I tried to connect to the Web console using my wifi and chrome on Android and it doesn't connect. I currently do not have a laptop to bind via Ethernet. What good is the app as it doesn't have any functionality when it's up and running. I am about to return this device and go to security solid modems by other vendors. Help. Ty.

S33 has intermittent internet connection

I have reset my modem and have rebooted my modem and I am still receiving no power signal. The mdrm has a solid blue light on. How do I resolve this issue? Do I need to replace my modem? My devices show signal strengths between 2-4 bars. My internet does drop service 3-4 times daily. I do have internet service and my cable provider has shown me that the signal strength is good. Thank you

Slow speed on new arris s33 modem

I just installed my new iris modem S33 and xfinity is telling me it is not sending enough speed.And they're sending a technician. I'm thinking on returning this, as my 13 year old Motorola did better and it didn't even have the ability for speed. Is there something I'm doing wrong? I'm about to return this product and either install my old one or get a netgear.

Arris Surfboard 33 Compatibility: TDS/Asus Mesh

My cable service is TDS in Oregon and I am using a stock modem supplied by the provider alongside Asus CT8 Router with two nodes. I would like to purchase a compatible modem to replace the stock router, and the ARRIS Surfboard S33 seems to be a good choice. Would this modem be compatible with the Asus mesh and the TDS cable service? Thanks for your time!

Arris S33 won’t power on

After working fine for 6 months, the modem will not power on. I’ve unplugged the power cable twice and have tried the reset button. Also checked all cables, etc.; this is the only component not working. It seems obvious, but is there anything I’ve overlooked?

s34 can't access web interface with direct connection

My s34 is directly wired to my computer via Ethernet 2.5 port (though I also tried the 1.0 port and the result is the same). I can access the web interface for about 15 seconds after a reboot of the modem, but then I have no access. I need the status page to show my ISP that the drops are due to infrastructure problems (upstream and downstream power), not my home network. I replaced the modem at their request and... Surprise, the problems are not any different with a new modem.I can connect to the IP for the web interface either direct connected or behind my wired ubiquity erx router, but only for the first 15-30 seconds the modem is on. What could be the problem here?To be clear, connectivity is fine when I'm trying to access the web interface.

Arris Surfboard S34 - Unable to access GUI portal and ethernet light is blinking

I just purchased this Arris Surfboard S34 modem from Amazon on September 28, 2024. Before I connected the modem to the router, I logged into the modem using 192.168.0.1. Once in, I setup my username and password. After COX activated my modem, I connected my PC to the modem using the 2.5 Gbps Ethernet port. Once my PC was connected to the Internet I can browse any website without any problems. However, there are two issues: 1 - the LED light on the 2.5 Gbps Ethernet port is blinking constantly, and the color is yellow. 2 - I tried to ping the modem using 192.168.0.1. The ping replies with: Request timed out. Also, if I type the same IP address in any browser, I can’t access the modem. The message: This site can’t be reached. Please advise. Thank you.

S33 - Xfinity tells me it's registered to another customer?

So I purchased an S33, brand new, from BestBuy on Saturday. I was not able to activate the modem with the xfinity app so they put me into contact with one of the CS representatives via text chat. After a long period of time they came back and said the modem could not be activated on the network because it was registered to somebody else, and advised that I contact the manufacturer. Here’s the funny part. Last week I purchased a different modem, from a different manufacturer, and from a different retailer. When trying to activate it I got virtually the same story - I was told it was a refurbished unit (that’s not what I purchased) and it was currently registered to somebody else. What are the odds of this happening twice? Pretty far out there I’d guess. Is someone out there spoofing MAC addresses? Does xFinity really not want me to own my own modem? They’ve been of absolutely no help. Is there somebody here that can help me? I was trying to access the live chat, which is suppos

Arris S33 - Won't lock to Optimum--Stumped...

Our Arris S33 has worked like a champ for nearly 2 years. Then, one evening two weeks ago, the modem suddenly dropped its connection to our ISP, Optimum. There was no general service outage, and neither rebooting; repowering, nor factory resetting the modem helped--it remained unable to lock to an upstream channel signal, though it could lock to one downstream channel (channel 28).I next disconnected the modem and tried reconnecting it to the cable at the point where the cable first enters our house--ahead of any other equipment or splits. Still no joy… The S33 gave the same result--no ability to lock to an upstream channel.I then contacted Optimum support, and they could not remotely communicate with the modem either, which convinced me that either there was a problem in the signal somewhere between the road and our house OR that the modem had somehow failed. An in-home Optimum service call was arranged.The tech who showed up confirmed everything stated above. He then swapped-in

S33/S34 2.5G port slow

I have Cox gigablast and was getting 940Mbps speeds with my Motorola MB8600. I’ve “upgraded” to the Arris S33 and S34 and I’m getting weird results with the 2.5G port. Both modem continue to download at 940Mbps when connected to the 1G port. However, when connected to the 2.5G port, I only get between 180-300Mbps. I’ve tried multiple laptops, desktops, and switches with 2.5G ports. I’ve also used Cat6a and Cat 8 cables but the results are all consistent. I would assume I would continue to get 940Mbps when connected to the faster 2.5G port. Also worth noting is that I do not get a link/connection light on any of the modems’ ethernet ports, but the respective activity light flashes green when connected to either port. And of course, I’ve rebooted the modem with and without the ethernet connected to either port. I returned the S33 thinking it was defective and the purchased the S34 which demonstrates the same issue.Is this a firmware issue or does the carrier need to enable the 2.5G port?

S33 Upstream Power Levels and Gibabit Speed w/Xfinity

Xfinity claims that Upstream Power Levels should be +35 to +50 dBmV. The S33 wants Upstream Power Levels to be +45 to +51 dBmV.A lot of Xfinity customers have +35 to +44.9dBmV Upstream Power Levels and they aren’t getting Gigabit performance.How do we fix this?

s33 orange and white light and intermittent internet connection with high pitch noise

Internet randomly went out and my S33 modem would do one white blink then turn orange and blink slowly and kept repeating the cycle. I tried a to restart it and even plugged it into a different outlet. Making a squeaky noise as well. Contacted xfinity and they are stating it’s the modem. Any help would be great. Also warranty is for another year. Now it’s just staying the color white.

S33 Modem Not Acquiring Downstream Channel on Sparklight

Greetings,In the past few days my S33 modem, which until now has performed perfectly well, has suddenly stopped connecting to Sparklight’s cable network. After investigating the interface, I learned that it was stuck at “acquiring downstream channel,” and after calling Sparklight learned that it had suddenly dropped off their network and as far as they could tell everything on their end was working fine. I’ve attempted several restarts and two factory resets, which have done nothing, and am not sure what to do next. I wanted to call or chat with Arris technical support, since this modem is in warranty until December 28th 2025, but the live chat option on their support webpage only says that it’s working without any interface for actually connecting to chat (in Firefox, Safari, or Chrome), and the call section doesn’t actually list any phone numbers to call. So I can’t do that, either. Does anyone have any suggestions for further troubleshooting activity or other suggestions for next st

S34 not compatible with Cox

I have spoken with two customer support folks from Cox trying to activate the S34. They both have told me it is not on their compatible devices list. I chatted with a Arris customer service agent who said that it is compatible and to use model “RARS34” but this did not help. Buyer beware.
