Configuring Security Settings for a Wireless LAN

Connection

Configuring security settings prevents unauthorized access to a computer or projector over the
wireless LAN. Settings are configured with the projector’s System Admin page, which can be
accessed with a computer’s web browser.
This section explains only the security settings of the System Admin page. For details about other
System Admin page operations, see “System Admin Page Operations and Settings” (page 33).

To configure security settings, you first need to establish a wireless LAN connection between the
projector and computer. For information about establishing a connection between a projector that
does not have security settings configured and computer, see “Using a Default SSID to Connect a
Computer to the Projector via Wireless LAN” (page 15).
