I have a G34 with Xfinity, 8 months old. Drops the internet and have to reboot several times a day. Going to fix it today or replace it, any thoughts?

Could you please confirm your subscribed internet speed plan and the name of your internet service provider?

When the internet connection drops, does it seem like the gateway is rebooting on its own?

Does the connection drops on both Ethernet and Wi-Fi?

We recommend reprovisioning the G36 and 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.
