SBG6950AC2 wont let me use internet though can connect

So got a SBG6950AC2 WiFi cable modem less than 3 months ago and yesterday was saying I didn’t have internet though showed me connected. I did a power cycle, went through my provider (Xfinity) all seems good there showing interest getting to router. I haven’t tried a lan cable due to not having one currently. I deactivated my service to modem. Not tech savvy enough to feel comfortable going in to change settings without confirmation might help. Then I did a full reset and still facing the same problem. I can’t find any customer support on this site besides you guys and hopefully can get some help before my zoom interviews!

Dropping connection & warranty claim

I asked a question a couple months ago and did not receive any assistance that helps or answers my question. I have a SBG7600AC2 and want to know how to submit a warranty claim without having to call customer service?  This has consistently dropped connections and restarted many, many times over the last couple of months.  I had my cable company here twice and they don't find anything wrong on their end.  I switched to a different modem/router and haven't had any issues since.  I had to hook up a new modem in order to have wifi.  So I would now have to call my cable company back and reactivate the problem modem so Arris customer service can tell me that it doesn’t work.  It took me quite a while to activate all my devices to be working with the new modem.  I am not sure I want to have to go through that again twice.  Is there no other solution?  Anyone?

send/receive light blinking on install

I’ve just received the SBG7400AC2 in the mail, and followed the instructions to get it set up. When it turns on, the top light and bottom two are solid blue. The middle light (internet connectivity) is off entirely, and the second light (send/receive) is blinking continuously. I am unable to connect using my service provider. I have let it sit overnight and tried again, as well as completely disconnecting and reconnecting it. Has anyone else had this problem, and how did you solve it? TIA!

How do I tell if it's Comcast, or my gateway router, causing random internet disconnects?

In the last several months I’ve had to power down/power up my “Xfinity-compatible” SBG6900-AC Gateway Router dozens of times because one or more of our computers or iPhones mysterious lose Internet connection. How does a Comcast Xfinity customer figure out whether it’s a problem with my SBG6900, or some kind of problem with Comcast Xfinity?   My SBG6900 error log shows repeated Critical arcane events like, “ No Ranging Response received - T3 time-out” and “ Started Unicast Maintenance Ranging - No Response received - T3 time-out” or “Honoring MDD; IP provisioning mode = IPv6, No Maintenance broadcasts for ranging opportunities received - T2 tiime-out”. It’s all but impossible to talk to a human Xfinity technician anymore; all phone support leads me in circles. The cynic in me also wonders if Comcast is trying to drive customers to exasperation who bought their own gateway routers, to get them to rent Xfinity’s equipment again, due to “growing incompatibility” or some such pretext. NOTE

Why can't I access the "Operation" section?

Once logged into the web interface, there are three headings at the top of the page: “Configuration”, “Operation”, and “Logout”.  I am guessing that “Operation” is where I can view traffic or logs and whatnot but when I click it, I am presented with another login page that will not accept my admin password or the password from the side of the physical gateway. I cannot find any documentation or resources explaining how to correct this. What am I doing wrong?

wired connection for ARRIS SBG7400AC2 not working

I have a ARRIS SBG7400AC2 router/modem to use with Xfinity. For a while now, the wired Ethernet  connections do not seem to be working, but the Wi-Fi works just fine. I have tried different Ethernet cables, and different ports, but the result is the same. I had the wired connections leading to me PC and printer. But now I can only connect to both via Wi-Fi. I do have a Blink doorbell dongle plugged into the USB port in the front that seems to work fine, too. I noticed this happen after we had a lightning storm one day, so I’m wondering if that was the cause. The router has been unplugged and restarted many times, but that hasn’t fixed the issue. Is there a way to test and see what the issue might be? I’m just trying to figure out if maybe there is a different way to reset that might fix things, or if there is something that just got fried internally for this to happen. Any insight would be appreciated. Thanks!

How do I change my firewall settings so I can get onto a website? I use this website for work and can access it anywhere but from my home unless I long in using my iPhone hotspot. If I use my home internet it will allow me to get to the website but when I attempt to log in it gives me a 404 (not found) Error

SBG7400AC2: Windows 10 not connecting to USB file share

Followed the step-by guide:https://arris.secure.force.com/consumers/articles/General_FAQs/SBG7400AC2-USB-Media-Sharing/?l=en_US&fs=RelatedArticleSuccessfully able to connect via MacOS. However, per the Windows steps, each time I try to go to the 192.168.0.252 IP, I get an error. As “192.168.0.252” I get “site can’t be reached,” and as “\\192.168.0.252” I get “file couldn’t be accessed.”What could be holding it up? I thought possibly it is trying to connect with my Windows credentials instead of my Arris credentials, but I assume I’d get a prompt if so. As I said, MacOS connected without issue, but Windows 10 will not. What are your thoughts? Thanks in advance.

SBG6700AC2 Better to use SBX-AC1200P Range extender or Mesh system

This is for my home network system.  I have 2 month old Arris SBG7600AC2. It works very well for my needs.  I would simply like some extended wifi coverage.  According to Oolka, over a cabled connection (not wifi) my internet service provides me 120 Mbps down and about 10 Mbps up.  I know we currently have the lowest service from our provider and I don’t expect much to change in the future to warrant paying for a faster connection.  I average 246 GB per month and at most 12.5 GB per day. I don’t have any bottlenecks or performance issues from an internet perspective. But I lose some wifi bars at both distance extremes in the house. That said, I’d like to extend my wireless range a bit. The structure is a 2 story 62 x 24 footprint. The current placement of the existing 7600 is pretty much in the middle.  I have some questions: 1. Would I be better off from a wifi range perspective to add a range extender (or two) or use one of the mesh systems?  If I use a mesh system, which one is best
