4.1 Automatic Connection

- After it detects the connection, the LED Ring will show green on your C4000BG when the Internet is ready for you to use. If you have a PPPoE connection, you will have to enter the user name and password provided by your ISP.
- Go to Set Up a Wireless Network if you wish to configure your wireless settings.
- If the automatic connection is not successful, check your connections and restart the Device. Also, make sure you have entered the user name and password correctly. If you still cannot access the Internet, follow the steps in the next section to manually configure the Internet connection.

- If a successful connection is established, the LED ring will alternate Green, then white, then solid green once normal active operations continue.
5.2 Setting up a wireless network manually
The wireless LAN on your C4000BG is enabled by default. To add a wireless
client to the network, use the settings found on the bottom label of your
