BT Broadband connections include FTTP/FTTH and FTTC connections, configurations on the Deco/Router vary depending on the connections available at your home.

For Deco

FTTP/FTTH (Fiber to the Premises/Home, Full fiber)

If you are a FTTP/FTTH or full fiber customer, it’s likely you’ll have an Openreach modem (or ONT) installed inside your house and an Wi-Fi hub(Wi-Fi router) provided by BT. You can either use Deco to replace your Wi-Fi hub or use both.

You will have double NAT in the network this way. If you’d like to avoid double NAT, you can then set up the Deco into AP mode, while you may note that you will lose some advanced features of Deco if Deco works in AP mode.
