customer Service is nonexistent.

Why can't you ever get in touch with a live person? Even the artificial Intelligence is always unavailable.

ARRIS 56FD change wifi name

I have been trying to change my WiFi’s name and password. I had success logging in once and changing it but the changes didn't take, I am not sure why. It was saved.  When I tried to login again none of the name or password combinations will work. (Original or new). Not sure where to go from here…

Is it possible to disable the LED blinking on the WAN ethernet port?

I have “Front Panel Lights” set to “Off under normal conditions” to disable the front LED indicator. This works wonderfully. However the WAN ethernet port’s LED is still present. With the 2.5Gb port connected to my mesh network, the LED constantly flashes green non-stop to indicate traffic.This is very distracting at night. Is it possible at all to force a solid color or add an option to disable the LED under working conditions?

S33 Replacement since there is no wifi internet

My S33 seems to be having the same issue as many others on this forum. Constant noise with orange light / light blue light. I checked with my ISP and everything is good on their end but still no wifi. I’m on the east coast and customer service isn’t open until 11am here. Need my WiFi backup and running ASAP. Wondering if anyone has had ARRIS send them a replacement modem and how long that normally takes.

Disposal of Arris VIP2262v1

What’s the best way to dispose of a ARRIS VIP2263 b1. Recycle? but then where? Just don’t want to put it in a landfill. If someone wants it, it’s yours. Just pay for packaging and shipping.

Unable to add modem to Xfinity account

The Xfinity installer called his tech support and they speculate that the box the modem came in was never correctly scanned by Best Buy, where I bought it. They said the “mac address” is the problem, and that I have to take it back to Best Buy for them to scan it properly. Anyone else have this problem?

Wrong default gateway address on SB 8200

I just recently purchased a SB8200v3 and am already having an issue with it.  After contacting my ISP to have it added to my account I was able to get network activity, but the first octet of my default gateway is 24 instead of my ISP’s 192.  I need to plug in directly to my modem and manually change the default gateway in order to log into it locally.Does anyone have any thoughts how to get this issue sorted out if the ISP says it’s an issue I should take up with the manufacturer? Not being able to get my home network back up and running is a slight inconvenience.

S33 -upload speed limited to 45mbps

Hello,I’ve 1Gbps/350Mbps internet now. I bought S33v3 to support this tier since MB8600 didn’t work good with it. But the upload appear to be limited around 45Mbps. ISP tech checked everything and I couldn’t find a problem and said this modem doesn’t support the higher upload speed.  Based on the event log, I think the correct config is not in place because some issue with either modem or the provisioning itself. I can’t believe S33 can’t support higher speed.Can someone tell what’s wrong here ?

403 Forbidden not resolved

I see that others are also getting the 403 forbidden message when trying to connect to the cable modem interface.  My modem is the SB 6190.  I tried EVERY suggestion listed in this forum, and chatted twice with Arris tech and we went thru all steps, no go.  I asked both Arris tech’s do I actually NEED to connect to the interface, and if so why?  Security reasons? Both tech’s told me to rest assured that there are NO security issues if the interface can’t be reached and UN / PW can’t be changed.  Is this true?  Anyone know if this is true?  If it’s true, why is there a need at all to connect to the interface?Really a terrible feeling to be locked out of the interface and not knowing if I’m now vulnerable to being hacked.  I’m going to get a new cable modem.  NOT and Arris.

Incorrect username or password on S34

I keep getting the same error message using admin for username and password for the password for the web access. I’ve also tried admin for password (all lower case).I then did a reset with the button on the bottom. The modem rebooted, but it still won’t take the default username and password. This modem was new out of the package and is successfully connected with my spectrum internet. Device Status button works fine. Any suggestions? Thanks

Enhancing Home Network Performance with Hybrid Cloud Solutions

Hello everyone!I’ve been researching ways to improve my home network performance and came across the concept of hybrid cloud technology. I currently use the SURFboard G36 modem and have been pleased with its performance for streaming and gaming. However, I’m interested in optimizing my setup even further with a hybrid cloud approach.I’m thinking of leveraging cloud storage for less-sensitive data while keeping more critical resources like gaming servers and my home automation system local for faster response times. A configuration could offer a perfect balance between local control and cloud scalability, allowing for both secure access to my data and easier management of connected devices.Does anyone here have experience setting up hybrid cloud configurations with SURFboard devices? I’d love to hear any tips or recommendations, especially concerning how well the system handles remote management, security, and overall performance.I’m also considering using the SURFboard mAX® Wi-Fi 6 sys

Another intermittent SB8200 internet drop case

My 14mo old SB8200 has started dropping the internet a couple times a day in the past week.  I see in other posts that I should follow a procedure to check the cable power levels, to make sure that part is OK.  First step is to do a direct ethernet connection to my laptop.  I don’t have an ethernet port or an ethernet-USB adapter.  Is it essential?  Can it be done wirelessly?Probably unrelated, but my ISP (Cox) is in the middle of “upgrading” and say they will take me offline today for a few hours.  Might there related “fooling around” be causing my recent connection problems?

As a small ISP / CATV provider how do we get current firmware releases for SB modems

Hello,We need to know how we go about getting current firmware images for our SB modems.  We are a small CATV provider who uses CASA vccap for a CMTS.  We own our own DOCSIS provisioning system, so we need to add current SB modem firmware to our modem firmware server.  We switched from Touchstone modems to Surfboard modems as Touchstone no longer exists.  we are mostly using SB8200’s and SB8300’s but we do have some other models   CheersCorey

Arris Surfboard S34

I just purchased an ARRIS Surfboard S34 as I upgraded to 800 mbs speed.  I have internet connection with a constant blue light on the front of the modem but the connection on the back of the modem is flashing yellow. Xfinity says it is not a problem on their end. This modem was a recommendation from Xfinity.  What can the issue be?  Thanks for any help.

SB8200 Firmware Update

I need a firmware update file for my SB8200.  I know it was mentioned to my ISP’s support line and they refused stating that they are not allowed to connect to customer owned modems and process updates.  At this point, I cannot update my modem and i’m having connection issues with reset connects and VPN drops which are impacting my ability to do my job. Can anything be done to get me an update file, please?
