Arris g36 drops internet constantly

Could you please let know the name of your internet service provider and the speed plan which you subscribed from them? 

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.

Cable signal levels are like the volume and clarity of a conversation between your modem and your internet provider. If the signal is too weak or too strong, it can cause communication issues—just like it would be hard to hear someone whispering from far away or shouting too loudly in your ear.

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:

If you find that the signal levels are not within the recommended range, we suggest contacting your Internet Service Provider (ISP) to have them reviewed and adjusted as needed.

For your reference, the downstream QAM levels are within the acceptable range. However, the upstream levels are not. Please refer to the acceptable signal level ranges below and compare them with the actual signal values from your G36 gateway to help identify the issue.

So, does that mean there is an issue with the modem then? We are replacing it with another soon, but this is all we have for now and it’s very unstable.

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.
