Note:
The SBG8300 supports using an Ethernet port connection for your data
input in place of an RF cable connection. You will be able to connect to an alternate
Internet connection and use your SBG8300 as your router and Wi-Fi source. This is a
useful feature if you choose to change your Internet service to a provider that is not a
cable operator. You can still use the SBG8300 as your Wi-Fi router.
You can enable or disable this feature which is available for the LAN Ethernet port
