I unplugged my modem and disconnected the coaxial cable and Ethernet cable from my modem.  I plugged my modem back in with the coaxial cable only.  It’s in the same location as before.  Now it keeps dropping the internet.  It’ll be on for 5 min, the no connection, then back on…..I did a reset by unplugging it as well as poking the little hole on the back.  Nothing fixes the problem

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

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).
