My Arris or Comcast?

If you model is G36, are the internet drops happening only over Wi-Fi, or are you experiencing them with wired connections as well?

If the issue is only with Wi-Fi, please ensure that the G36 modem/router is placed in an elevated position and away from obstacles like concrete walls or microwave ovens, as these can interfere with the Wi-Fi signal and weaken the connection.

If the issue occurs on both Wi-Fi and wired connections, 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.
