Step 2 If you configured a different LAN interface than the default interface, be sure to connect your PC to the LAN interface that you configured. For example, if you configured FE 0/1 and not FE 0/0 as the LAN interface, be sure to connect you PC to FE 0/1.

Step 3 After preparing the PC, reconnect your PC to the router by entering the new IP address that you gave the router’s LAN interface in the browser (http://new IP address). For example, if you changed the LAN IP address to 10.20.20.1, you would enter http://10.20.20.1 in the web browser to connect to your router again.

Step 4 After reconnecting, test your WAN connection to verify that you can connect to the Internet.

Testing Your WAN (Internet) Connection

You can test your connection to the Internet by pointing your browser to a remote website, such as www.cisco.com. If you are able to connect to the remote website you entered, your WAN configuration works properly.

If you cannot connect to a remote website, you can use Cisco SDM to troubleshoot the connection by doing the following:

Step 1 Click Cisco SDM in the Tools menu to launch Cisco SDM.

Step 2 Log in to Cisco SDM and click Interfaces and Connections.

Step 3 Click the Edit tab and select the WAN connection you want to test.

Step 4 Click Test Connection and follow the instructions that appear. Cisco SDM reports on the possible problems and recommends actions.
