Modems

Hello, My ARRIS S33 modem stopped working unexpectedly (solid amber light then light green light and high pitched noise). I purchased a similar modem and tested its power cord on my modem and it worked perfectly with the new cord, so the original power cord was faulty. Since my modem is still under warranty, I want to request a replacement power cord free of charge. Can someone point me in the right direction please? Thanks!

I am trying to set up my Ring Doorbells and it needs to access the 2.4GHz. I can only access the 5G. 

How can i check which devices are using my modem and how much internet data each device is using?i used to work from home till Dec of 2023, and now that i don’t anymore, i figured my data usage will drop, but it’s doubled since Jan of 2024. My ISP (Comcast/Xfinity) are unable to give me the info because I’ don’t have one of their Modems, and Surfboard couldn’t help because my warranty expired a yr ago. Side note: I have a suspicion that it’s because my roommate has been on Discord ALOT lately, but I don't want to stir that pot till i know for sure. 

Guten Morgen, kann mir hier vielleicht jemand sagen, wie ich den Router und somit das Wlan für eine gewisse Zeit ausstelle ohne den Router ausschalten zu müssen?Gibt es die Möglichkeit eine Zeit einzustellen “von-bis” das Wlan an ist? Vielen Dank für die Hilfe 

Hello community members ,I recently purchased a refurbished Arris S33 v2 for my 1g connection from Optimum.And I am getting random internet cuts for like 1 minutes and comes online again on its own.I have a Mikrotik router behind S33 modem.when modem goes offline I can clearly see the public ip on wan interface gone and replaced with 192.168.100.10. I don't have to reboot or do nothing it comes online on its own.and below is my log≈=========No Ranging Response received - T3 time-out;CM-MAC=edit:personal information;CMTS-MAC=edit:personal information;CM-QOS=1.1;CM-VER=3.1; 31/12/1969 18:50:46 3 DHCP failed - RS sent, no RA received;CM-MAC=edit:personal information;CMTS-MAC=edit:personal information;CM-QOS=1.1;CM-VER=3.1; 12/5/2024 13:24:59 3 Successful LAN WebGUI login from 47.219.233.94 on 24/05/12 at 1:34 PM.

I am having trouble activating my SB2800 modem. I downloaded the Surfboard app as suggested but once I opened the app, it said it only applied to certain products. The system seemed to allow you to search for another product but I never got the product list. So I am stuck.  Is it better to just go through my internet provider?

I purchased a new SB8200 (and TP-Link router) to replace a COX Panoramic combo modem/router that I was renting.  I have one problem:  the SB8200 will not reconnect when power cycled.   Specifically, unplugged, then plugged back in.  The send and receive lights will go solid green, but the online light just blinks.   Eventually (minutes), the modem appears to restart and the lights cycle through startup phases, resulting in the same status described above.   It seems like the modem will do this forever (I give up after 30 minutes).   Using the management webpage, it appears each reset cycle is using an different set of channels to attempt the connection.I only way I’ve discovered to get the SB8200 to connect is to leave it unpowered for several minutes (like 10), then plug it in.   Only then will it successfully establish a connection.I’ve validated that all signals levels are good (per the SB8200: CABLE SIGNAL LEVELS FAQ).   I’ve had COX at my house, and they’ve

I purchased an SB8200 to connect to Optimum after having them scan the MAC address at their local office the modem will not connect.  The power light is green downstream and upstream lights stay solid greed and internet light flashes green.    This stays this way for several minutes then the internet turns solid green for maybe 5 seconds then all lights except power go out and the process repeats.  I have had them reflash the service, confirmed the MAC address and even changed my service coax cable.    I had this issue about 1-2 years ago when I upgraded a modem at another location and after much ado it was resolved but I don’t remember how it was resolved.  I really feel this is an optimum side issue but any advice would be appreciated.  

I'm getting less than 100 mbps on my devices. I'm paying for 500 mbps. My cable company says it's my Arris that is slowing my speed. How can I fix this??

Trying to factory reset our SB6183. Connected it to my laptop with a ethernet cable using a docking station (laptop not connected to the internet). After agreeing to and clicking “Do you want to proceed?”, what is supposed to happen? It redirects me to a web page that just states there’s no connection.

When I used to do a Speedtest that used to record the speeds. It worked all of March all of a sudden it stopped working. What is the issue? What should I do?

How can I log into my SurfBoard modem

Hello,I have been having internet issues for a couple weeks, it will randomly drop for less than a couple minutes and come back, there is zero consistency on when it happens. Just enough time to get kicked from a game, for my phone to reject the wifi, etc. Cox is basically no help and just tells me to buy a new modem with zero reasoning as to why, they just want my to buy their hardware and I refuse. My modem is about 4 ½ years old. These are the logs I got from event log today after my internet cut out, do they show anything? 6/5/202417:58:43    3    Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=*;CMTS-MAC=*;CM-QOS=1.1;CM-VER=3.1;6/5/202417:58:43    3    Unicast Maintenance Ranging attempted - No response - Retries exhausted;CM-MAC=*;CMTS-MAC=*;CM-QOS=1.1;CM-VER=3.1;6/5/202417:58:43    3    16 consecutive T3 timeouts while trying to range on upstream channel 8;CM-MAC=*;CMTS-MAC=*;CM-Q

Internet says connected with no internet. Internet provider says its the modem. 

If DECO router is connected to Ethernet port 1, will port 2 be ok to connect to my WD external drive?

When signing into the web manager tool for my SB8200 cable modem, it responds to both 192.168.111.1 and 192.168.0.1. This causes a problem for me in that a router in my network can only be managed using 192.168.0.1 and when that is entered, it only goes to the Arris login screen. I cannot get to the router no matter how I’ve tried.Can I, as an end user, somehow delete the 192.168.0.1 IP address from my SB8200?

I have to remove four Systimax 2.0 jacks from a patch panel.  These jacks click in easilu, but I cannot remove them to save my life.  I’ve tried a small screwdriver on all sides of the jacks, but they will not come out.I’m on a time crunch with this project, and I need to remove the jacks by Thursday.  If there’s a tool I need to order, I’ll need to do it today.Thanks!

So xfinity was in our neighborhood and they sent a notification saying there would be a service interuption and would be restored by 6:30am the next morning and that came and went then i called xfinity and they said it should be resolved soon and it never did so they sent a technician and he couldn't figure it out the only thing he could come up with was that it was an issue with our router/modem but it couldn't be because our router is brand new. So he got a wifi router from his truck and hooked it up and it worked. So i don't understand how. We have never had a problem with our modern before so all of the sudden after xfinity did something it didn't work anymore.

Before I buy the S33, does the Eero 6+ router/extenders work well together?

Tech was here today and eliminated everything but the modem I got yesterday. So I go to Best buy and swap it. Get home and this modem has exact same problem (that's 2 new failures in a row). I can't expect that kind of new-bad rate from Arris, can I?

My modem just stopped working randomly. I restarted it multiple times. I tried resetting it by pushing the reset pin up to 30-60 seconds, but the white light never changes. Is there usually a visible confirmation that the reset worked?I finally had a comcast technician come out and I am using a rental modem.But just in the off chance somebody knows the problem, please help. The white light stays on and never changes colors. Also, can we ship the rma back in the original retail box only? It is pretty well protected in the retail box.

I have a Netgear router with ACCESS CONTROL turned on but NOT blocking new devices. My S33 modem seems to have valid connection lights (solid blue) but none of my wifi devices have internet access. Connected/No Internet. Everything works fine with my older cable modem….

I am trying to install my new S33 modem however it is not an option in the app for installation so I don't know how to set up our modem 

Purchased a S33 V2 but when I login to the Arris portal it states that the hardware version is V1.0.  Do I actually own a S33 V2, or did they put a V1 in a V2 box. I searched this issue, and the only answer seemed like a canned response from the manufacturer saying they source components from the same places - this is not an answer to the question being asked.

Hello, Yesterday afternoon my internet cut out and I have been unable to restore it. I checked with my ISP and they aren’t showing any outages in my area, and tried resetting my network on their end but are unable to communicate with my modem. The upstream light on my SB8200 consistently blinks despite resets and factory resets. I logged on to my Connection pages and Event Logs.On my connection page it shows Acquire Downstream Channel-813000000 Hz -LockedConnectivity State-In Progress- Upstream Parameters AcquiredBoot State-In Progress-UnknownConfiguration File-In Progress-Security-Failed-BPI+DOCSIS Network Access Enabled-Denied  My downstream and upstream bonded channels seem to have proper power and SNR outputs.On my Event Log Event Level 3 with description “No ranging response received - T3 time-out”Event level 5 with description “B-INIT-RNG Failure - Retries exceeded” Thank you for
