SGB8300 Connected but no Internet

I am having issues connecting to the internet with my new SGB8300 modem.  Service is through Cox and they confirmed that they are seeing the modem and everything on their end is connected.  I am unable to get connected via both wifi and LAN line.  The error is connected but no internet.  I have restarted/reset the modem several times with no avail. Any help would be greatly appreciated on how to get connected to the internet.

Intermittent / no connection

I bought an 8300 so I could turn in our Comcast rental wifi modem. I selected the 8300 in part because it advertised the highest square foot coverage. We have a basic Xfinity plan - 75 Mb, and that has always been plenty (It was plenty for us at 25 and 50, back in the days when those were the basic plan data rates)The 8300 has so far been much less reliable, especially for my older Win7 laptop, which won’t connect at all despite 3 bars and 30 foot distance - almost line of sight location...my laptop connects only to our extender for the kids rooms down a hall, and that only intermittently. Out of curiosity I tried configuring the 8300’s guest network for 2.4G - still no joy.I turned on WiFi band steering and that somewhat helped, allowing me to connect but still only via the extender.Ideas anyone?

Continues disconnection of 24. wifi on SBG8300

As the title states, I received my SBG8300 modem/router two days ago. I immediately noticed that the 2.4 Wifi kept disappearing, and I lost connection. I’ve factory reset the modem, and the problem persists, and now my Alexa and Smart Life app is failing to connect since it requires 2.4 wifi. The website shows it is active.This is one of many problems I have experienced. I could use the web but not the mobile app, as it wouldn’t connect. Now I can use the mobile app, but the web won’t connect.Is this a product defect?Update: I got the Alexa and Web working. I’m still experiencing 2.4 wifi dropping while the app and web state it is online.

Audio cutting out during virtual meetings?

I recently installed an Arris SGB8300. Prior to installing, I almost never had issues with audio during my meetings. Now, the audio frequently cuts out for about 3-5 seconds. I can still see peoples’ mouths moving and the live captions pick up what they are saying but I cannot hear it. During meetings, I am connected to the 5Ghz network. I have Breezeline/Atlantic Broadband for an ISP. Here’s what I’ve tried:--reset gateway--connect to ethernet--turned off guest networks--audio with multiple sets of headphones (corded and wireless) and straight from computer speakers--happens in both Teams and Zoom calls, also happens when private listening to Roku streaming--run speed tests (very fast internet) and wifi analyzers--manually changed network channelThe only thing that has fixed it without fail is switching to my phone’s hot spot, so I am pretty certain it is the gateway. Is there a setting I should be looking for that I am missing here? I am pretty fed up with it and ready to send it bac

SBG8300 Periodically Drops Internet

I have an SBG8300 modem/router connected to Comcast/Xfinity Cable.I bought it from BestBuy last month, and it was working completely fine in the first few days (around 5 days). However, it periodically loses internet connection about every 2-4 days, and I have to unplug and plug back the modem each time to restore the connection. I called the ISP customer service, and they said they had updated the settings, but the same scenario kept happening afterward.Is there any possible reason for this? The WAN status when the internet is not working is similar to the one when the internet is working.

Arris SBG8300 compatibility

I now have AT&T fiber optic using their modem/router in my house. Previously I had Comcast cable and used my Arris SBG8300 for WiFi.  I have a Cat5 cable running from my house to my detached garage which I used in the past plugged into my Arris Model SBG8300 (house) when I had Comcast Cable. The Cat5 cable was plugged into a laptop I used in the garage. My question is, can I plug my Arris into the Cat 5 cable in my garage, connected to my AT&T Router/Modem (house) and use it for Wi-Fi for some remote security cameras in my garage?

SBG8300 No Internet

I recently got a SBG8300. I registered it with my ISP, Cox, and set it up. The solid green led indicator is on and I verified through the admin page that it was assigned an IP. However, the modem doesn’t seem to be able to access the internet. Both Ethernet and the onboard router aren’t able to provide internet access

randomly unable to access secure sites

I am randomly not able to access internet secure sites. When i connect to my wifi it states the connection is secure and have internet access and i do indeed have internet access. I am able to access nbcnews.com and other common non secure sites. Yet when i try to access a secure banking site or similar i am getting the connection is not secure message. it doesn't matter if it bing chrome or firefox. i have run network diagnostics and it states it is not finding a problem. randomly it will start working on its own with me not doing anything to correct it. For example while i was typing this on a different laptop i asked my wife to see what the error was, she said she couldn't tell me because it was now working. I have factory reset, Reloaded my network adapter. turned mac filtering off, restarted modem, played with firewall settings on cpu and router  i still have this issueSometimes one of those attempted fixes may work but mostly they don't and it will start working by itself for a t

Xfinity can't activate new SBG8300...

Just purchased this modem and tried to activate on Xfinity and the tech I was working with was unable to see it.  The top LED on the front was a solid green, and the bottom one was blinking green.  After providing the MAC address to the tech and waiting, I was never able to get a proper internet connection.  I WAS able to get their ‘activation’ screen up, but when following all the steps I would end up back at the initial activation screen. To me this sounds like an Xfinity problem, but the fact that the tech was unable to ‘see’ my modem makes me unsure.  When we were done I just plugged my old modem back in and all worked fine.  So now my new modem is waiting for me to make another run at this whole installation.  He seemed to think that there may be a problem with the new modem, which is why I am here to see if anyone has any ideas.   I really don’t think I should need a tech to come install this.
