Issues when attempting to access the "Operation" section of Arris Surfboard SBG6950AC2

I am attempting to access the "Operation" section of my Arris Surfboard SBG6950AC2.   When I select the option and put in my credentials used in the “Configuration” I get a message that says:Invalid user name or password, or your access has been locked due to multiple failed login attempts!”How do I clear this issue?

Router not working – only power light on Model: SBG6950AC2

I purchased this router from Walmart in September 2023.Only the power light is on; no Wi-Fi or internet connectivity. I’ve tried restarting and factory resetting the device, but the issue persists. I don’t have the printed receipt, but I’ve attached a screenshot of my credit card transaction from that time as proof of purchase. Please let me know if this is sufficient for a warranty replacement.

SBG7400AC2 briefly drops wi-fi many times a day

Hi folks! Need a little guidance. I recently changed over to using an Arris SBG7400AC2. My ISP (Xfinity) kept bugging me that I needed a newer modem (even though I had noticed no issues or changes using my previous one) and the SBG7400AC2 was on their list of supported devices, so I picked one up and have been using it for about a week. The wifi speeds and connection strength are just fine, but several times a day the wifi signal cuts out completely. It pops back on quickly, within like 5-10 seconds, but it does drop fully for long enough to do things like interrupt my VPN when working from home, drop from the lobby if playing a game, lose voice chat connection, etc. I only connect to the internet via wifi as the place I live is not setup for reasonable wired connections, and the wifi has always been plenty sufficient for my needs! Wondering what I can do to stop those intermittent losses of signal.

Only Power LED light on SBG7600AC2

How do I fix my SBG7600AC2 WiFi cable modem?The power indicator light is on, but no other status lights turn on. No send/receive light, online light, wireless lights, or WPS light. My WiFi network is not being broadcast or not discoverable when I try to connect my devices.I have unplugged the power cable for 15 seconds, and power cycled the modem, but it still does nothing except show a power light.I also checked that the coaxial cable is tight against the back of the modem and tight against the cable outlet on the wall.

SBG7600AC2, constantly rebooting on its own

We got a the new modem through amazon, it is the SBG7600AC2, the device worked fine the first day however it started to frequently resets on its own. We thought maybe the cords were the problem and had it replace. We have also moved the device in a more open space. We contacted amazon about it and they sent a replacement but that one also had problems…. the first one had intermittent issues and the second one had docsis health issues and wouldn’t even connect. I had talked to my service provider about it. Is there any ways to fix the intermittent issues or docsis health issues so i can return one of them at least??

No 2.4ghz with new SBG 7600AC2

I purchased a new (not renewed) SBG7600AC2 a couple of weeks ago. Within a day, we began having issues with the 2.4ghz network. I changed the security settings based on recommendations on this site. That worked for about 12 hours and then no internet again. We’ve rebooted the router multiple times and although that works, the fix only works for a few hours and then we have no internet again. Most of our devices are now on the 5ghz network but we need the 2.4ghz network for an older but often used laptop. Do we just need to return the router and get a new one? Or is there a fix that will work AND last more than a few hours? I would appreciate any help! Thanks!

SBG7400AC2 initial setup

I am attempting to setup a SBG7400AC2. Upon connecting the coax and power, the send/receive light continuously flashes and never turns solid as mention in the setup instructions. I thought this was because a firmware update is being performed, however, the update never seems to be completed as the light never stops flashing. What do I need to do to get the send/receive light to go solid?

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?

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?
