SBG7600AC2 online light not stable

Having an issue with my modem that was working fine a couple of days ago. Moved into a new place and went to set up the WiFi. Contacted Xfinity and got it set up. They had to send someone out here because the modem wouldn’t activate. He got that activated because the coax wasn’t in the right port on their end but now it’s activated and they can see the modem on their end. we are still having the issue where even though they can see the modem and are sending signal to it, it’s not receiving the signal so our online light just keeps blinking. Every so often the up/down light also starts blinking again. The WiFi pops up in our settings on our phones but says there is no connection and doesn’t load any pages. we have been in contact with Xfinity support and they have strongly been suggesting that it’s an issue with the router which I don’t understand if it has been working fine just a few days ago at the last place. Any help?

SBG7600AC2 WiFi intermittency

WiFi signal is intermittent. Connections are fine using direct Ethernet. I’ve restarted multiple times and have left it unplugged for 48 hours. Signal is there, but intermittency increases with time. Anything I’m missing?

Surfboard SBG7400AC2 Disable Wi-Fi Networks

All of my devices are hard wired. Can the WiFi be disabled, or does the router not broadcast if there are no devices connected wireless?

Slow speed internet when try connecting the modem from 1st floor and modem is on second floor - SBG7400AC2

When I run a speed check on my Apple iPhone, I get 279 Mbps on the first floor. The SBG7400AC2 is on second floor. When in the room with the modem, I get as high as 650 Mbps. Can I turn off the Wi-Fi on the modem, maintain the cable input and use another device for Wi-Fi with a device on second floor and another on first floor. I have an option of the first floor being hard wired if needed. This is where I use laptop and stream on main TV. Thanks.

Ethernet (wired connection) on SBG7600AC2 not working.

I just noticed that my Ethernet connection does not work from my modem. The wifi that I use daily is working just fine, but I recently noticed that my only wired connection is no longer working. My only Ethernet connection is my security camera system, and I have not checked to see if it was online in months, so who knows how long this issue has been going on for. I have tried to connect the Ethernet cable to different devices and use different Ethernet cables and reset the modem to no success. I am wondering if there is an easy way to tell if the Ethernet ports are broken or if there is some way to reset them. Both the green and orange lights are always on for all 4 ports even when nothing is connected. Is this normal? Or does this in itself indicate a problem? There was a power surge in my neighborhood a year ago. Could this have damaged the Ethernet ports but not the wireless Cabo ability of my modem? Any information would be appreciated. My modem is no longer under warranty.

Testing internet port access

I have updated the Arris cable modem/router with the information that was provided to add a virutal server/port forward. How can I test that the changes were implemented correctly? SBG7600AC2: Port Forwarding Setup However, the Arlo hub is still not being recognized by the mobile app or the My Arlo portal. What troubleshooting can you provide? Thanks

Latest Firmware for the SBG7600AC2

I saw two questions on this topic and the response was that the latest firmware is pushed out to the internet service provider. But my situation is I chose not to use any router from the service provider and purchased this on my own. So I would have thought I should be able to update the firmware on my own as well (as and when there is a firmware update).

Xfinity blocking port 80

I have the Arris SBG7600AC2 as the cable modem and wireless router for Xfinity service. When I try to add the Arlo Netgear camera hub, it cannot get to it because port 80 is blocked. I set up port forwarding on the Arris but the port does not seem accessible. How can I troubleshoot this issue?

Impossible to enable the DCS protocol in the 2.4 GHz band. My modem/router is the SBG7600AC2

I have been checking the tools of the 2.4GHz band to make it better and I found the dynamic channel selection that will be so helpful to me. However, to enable this one remains in gray; I have my router in auto for channels but in the advance part of this one is not letting me turn on the DCS. Also, I am steering the band with the 5 Ghz. I will appreciate your help :)

Wi-Fi Calling not working with SBG7400AC2

I cannot get Wi-Fi calling to work with the SBG7400AC2. I have Vyve cable internet and Verizon cell service. This modem is new, and I had the same problem on the previous Surfboard that we were renting from the ISP. Also, I had this problem on my older phone (Galaxy S8+) and thought it was because the phone was so old, but same thing is happening on the new phone (Galaxy S23 Ultra). I initially set the modem up using the Surfboard Central app and just accepted defaults. I did just login to the web interface to see if anything was blocked on the firewall. A Google search suggested enabling IPSec, PPTP, L2TP, and VPN Service for a Netgear router. Under Firewall settings, IPSec, PPTP, and L2TP pass-through are enabled. I can't find anything related to a VPN, and I can't imagine that would be the issue. This would be merely a nuisance, except often I'll miss calls and cannot send or receive texts when the phone has decided to try and use Wi-Fi calling. The workaround once I've realized it

CANNOT LOG INTO SURFBOARD ON PHONE

I have been trying for hours now to activate the service for this modem. I followed all steps, download the app, set up the SSID, and it says that I successfully connected to the wireless gateway. When I go to the next page to login to the wireless gateway, an error message comes up saying “cannot connect to the wireless gateway.” When I try to click on the links for “Supported ARRIS devices” it just brings me to a blank page on this website. PLEASE HELP!!!
