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

security up dates for SBG8300

Are any software updates ever created for my Wi-Fi cable modem/router ARRIS SBG8300?How often should I replace my router/cable modem for security sake? The model I am using now I purchased in 2020 would it be out of date?

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.

"Connected, No Internet" - ARRIS SURFboard SBG8300

ARRIS SURFboard SBG8300 DOCSIS 3.1 Gigabit Cable Modem & AC2350 Wi-Fi Router Purchased this modem/router combo last month so that I could stop renting one through Midcontinent. The issue below has occurred intermittently since then, but worse over the last 2 weeks. I am not well-versed in this area, but will explain the best I can. I receive an error - every day - of "Connected, No Internet" on my Hisense android TV. Other devices (phone, laptop) will also disconnect when this happens. I've rebooted the modem (and affected devices) multiple times. My TV network settings will show "Connected - Signal Strength Excellent" but no wifi access. When I reboot the modem, I'm able to reconnect the other devices, but the TV will usually continue showing the error. (As of the time of this post, the TV is connected to wifi and working). I have a DVR security system connected to the modem via ethernet cable, which is unaffected by this connectivity issue. My current service is Midco Internet 5

Surfboard SGB8300 Firmware updated and slow speed

New modem/router. Subscribed to Spectrum 1G internet. Speeds slow - 30-90 Mbps with cable, about the same over Wi-Fi.Called spectrum, tech came out and suspects device needs a firmware update. Speeds were good out the cable - 800-900Mbps. When installing, I remember the blue/green flashing.Tech was kind enough to look in to it a little bit, but we can’t tell if the firmware on the device is most current.In the manager, it shows firmware 01.01.139.NCS installed. Is that the most current? any other advice would be appreciated.

Problem connecting devices to SBG8300

I am totally not technology savvy. My problem is connecting 3 mini Blink cameras and 2 older laptops to the SBG8300. I reset the mini Blinks and they won’t recognize the 8300 unless I unplug the router for 10 seconds. Then they may or may not recognize it, and when they do I enter the wifi password. Then they disconnect a few minutes later. Same with the older laptops. I have 2 laptops, 2 phones, and smart TV that have successfully connected without problems. Any idea’s why these camera’s and older laptops don’t connect. The problem started immediately after setting up the 8300. Hopefully this makes sense.

SBG8300 internal time is floating around - How do I perminantly set it?

I can’t seem to lock the router time and it floats intermittently. I don’t know if there is a problem tracking time or it’s getting set by 1 of the 3 included Time Servers incorrectly. Setting Automatic vs Manual seems to have no effect.Just bought a SBG8300 and it works great with exception of Parental Control and blocking timeframes for different devices. Behavior is intermittent and unexpected of when a block happens. After some trouble shooting, I noticed the time display if floating all over the place. Sometimes 10 hours ahead, sometimes 8 or something. Once I hit the “Save Time Settings” button, it snaps back to the correct time I’m in (Pacific Time), but if log out and log back in 20 minutes later, it may or may not be off. User Steps: > Admin page https://192.168.0.1 > Gateway > Summary > Time (page is https://192.168.0.1/time.php) > Observe: “Router Time” value. Time Servers:clock.via.net ntp.nasa.gov tick.ucla.edu

I set up my email and password on my Arris surfboard gateway and i can login via the 192.168.0.1 IP address but when i use the same email and password for the surfboard web manager it responds with incorrect credentials and won’t allow me to login. I don’t understand this as they are supposed to use the same login info. Why does the surfboard app not let me login?

No solid lights on start up

I’ve had a lot of issues with my internet since I moved into my apartment. Finally someone at Comcast told me my modem was incompatible with my speed so I bought an SBH8300. I’m trying to set up the modem and the lights are constantly flashing. The internet light blue and the wifi light green. They were both solid green like the manual says they should be for just a second and then started flashing again. I’ve tried contacting Xfinity but they’ve been useless and apparently arris doesn’t have a customer service line anyone can call. So I am here. Help me.

Can't access Admin Portal!

Unable to login in with default admin username and password. Keep getting Invalid user name or password, or your access has been locked due to multiple failed login attempts! I can admit, i went in a changed the names and passwords for the network and saved changes before changing the admin login credentials. Also, the router came with 4 connection options (2 standard and 2 5G- one for home and guest each). However, the site only allowed ne the option to change two and the other two are still available with the default names and default password. Any suggestions to access and manage my router through the admin portal?
