In order to set up a Cisco Small Business router with a DSL connection, perform these steps:

1. Verify Internet Connection

2. Connect the Devices Together

3. Check the LEDs

4. Set up a DSL ISP on a Cisco Small Business Router

Verify Internet Connection

Connect the Broadband modem to the computer using an Ethernet cable without the router installed and make sure that the Internet connection is active. If not, contact your Internet Service Provider (ISP).

Note: The image may vary depending on the computer and modem you are using.

Once an active Internet connection is established through the modem, complete the steps in the next section in order to connect the modem and the computer to the router.

Connect the Devices Together

After you verify that you have an active Internet connection, connect the modem to the router's Internet port and the computer to any of the four Ethernet ports.

After you connect the devices, complete the steps in the next section in order to check the LEDs.

Check the LEDs
