Please ensure that only one Ethernet connection is used at a time on the S33. Although the device has two Ethernet ports, both should not be connected simultaneously.

The S33 is a standalone cable modem and does not include a built-in DHCP server. As a result, when your internet service provider (ISP) activates the modem, it typically assigns only one public IP address, which supports a single internet connection.

If you wish to use both Ethernet ports on the S33 simultaneously, you would need to contact your ISP and request the activation of a second public IP address. However, please note that not all ISPs offer multiple public IP addresses for residential customers.
