I have an ARRIS SBG8300. I have an issue where the Ethernet and WiFi both lose internet connection or is slows down to around 2 mbps download speed. The problem is intermittent and started a few months ago. I have had Spectrum out 3 times now and they claim nothing is wrong with my service. I tried swapping out modems and it didn't fix the issue. Today, my I ternet went out but none of my neighbors lost connection. I noticed that the Wifi light was completely out and the internet light was solid green. I had no internet on Ethernet or WiFi though. Does anyone know what the light combination means or have any ideas on how to fix my issue?

When the internet connection drops, does it seem like the gateway is rebooting on its own?
Also, when the connection is lost on both Ethernet and Wi-Fi, do the Wi-Fi network names disappear as well?
We recommend checking the cable signal levels within the gateway. If the signal levels are out of the acceptable range, they can lead to the kind of connectivity issues you're experiencing.
When the signal levels are within the recommended range, your modem can maintain a stable, high-quality connection to the internet
Please refer to the link below for instructions on how to check your cable signal levels:

The cable signal levels displayed on the interface page reflect the signals being transmitted by your Internet Service Provider (ISP).
If you notice that these signal levels are outside the recommended range, we suggest contacting your ISP to have them reviewed and adjusted accordingly.
While ISPs may have their own approved signal ranges, for this gateway to function properly, the signal levels must align with the acceptable values outlined in the reference article provided.

Thank you. I chalked the signal levels according to the link you sent and at the moment they seem fine. I'm not sure if I should do this while the outage or slowness is happening though. My Internet is currently working.
As for your first question, the gateway does not seem to reboot on its own when the connection drops always. Often I have to unplug it and plug it back in.
When the connection to the wifi is lost, my devices all still stay connected to the wifi. My phone and computer will say connected/no internet.

We recommend checking the cable signal levels at the moment the connection drops.
This will help us determine whether the issue is related to the signal quality or from another source. By ruling out signal-related problems, we can narrow down the root cause more effectively.
And if you notice that these signal levels are outside the recommended range, we suggest contacting your ISP to have them reviewed and adjusted accordingly.
