product’s CD. For instructions for installing the TFTP server software,

Clicking Upgrade Firmware displays a prompt that asks you to save any
changes you have made to the router’s configuration before proceeding
with the firmware upgrade. If you click OK, the Upgrade Firmware screen
is displayed, as shown in Figure 13.
