I have Optimum ISP with 1G speed. Optimum says there’s no issue on their end. Have had to reboot modem three times this week. Today service has dropped twice and the modem won’t reconnect, keeps flashing green light. Suggestions?

Thanks.

We recommend checking the cable signal levels within the modem. 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.
