Chapter 2 Installation

Installing the Router

Step 2 Connect the other end of cable to the available port on the modem.

Follow the instructions provided with your broadband modem to determine which port on the modem to connect to. Turn on the broadband modem if it is not already turned on.

Note If the factory default configuration does not allow you to connect to the Internet, it is recommended that you configure your router using the Cisco Router Web Setup (CRWS) software. The CRWS software is installed on your router at the factory. See the “What to Do If You Cannot Connect to a Website” section on page 2-22for instructions on starting the CRWS software.

Connecting a Terminal or PC to the Console Port

The console port is a service port to which you can connect a terminal or PC in order to configure the software by using the command-line interface (CLI) or to troubleshoot problems with the router. To connect a terminal or PC to the console port, follow the steps given after Figure 2-4. (Figure 2-4shows a Cisco 831 router, but it also applies to a SOHO 91 router. The connection procedure applies to both the Cisco 831 router and the SOHO 91 router.)
