When this happens, check the SSID on the Wireless standby screen being projected by the projector you want to connect to and click the same SSID on the dialog box. Next, click [OK]. 17 Configuring Security Settings for a Wireless LAN Connection 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 projectors System Admin page, which can be accessed with a computer’s web browser. This section explains only the security settings of System Admin page. For details about other System Admin page operations, see “System Admin Page Operations and Settings” (page 32). Security Setting Flow 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 13). Establishing a wireless LAN connection between the projector and computer On the computer, log in to the projector’s System Admin page. On the System Admin page, select “Setup” and then “Wireless Setup”, and configure the following settings. • Assign a new SSID to the projector. • Select a security protocol (WPA-PSK, WPA2-PSK, or WEP). • Enter the passphrase (or WEP key). Apply (register) the above settings to the projector. (At this time the wireless LAN connection between the projector and computer will be terminated.) Click the Wireless Connection 3 [Reconnect] button. On the dialog box that appears, enter the passphrase (or WEP key). This will establish a wireless LAN connection provided with security in accordance with the selected protocol. 18 Configuring Security Settings This section explains the procedure for logging in to the projector’s System Admin page from a computer and configuring wireless LAN connection security settings. To log in to the projector’s System Admin page 1. Perform the procedure under “To use a default SSID to connect a computer to the projector via wireless LAN” (page 14) up to step 6 to establish a wireless LAN connection between the projector and computer. 2. On a Wireless Connection 3 window, click the function menu button and then click [Admin Screen] on the menu that appears. Function menu button • This starts up the computer’s web browser and displays the projector’s top System Admin page. 3. Click “System Admin”. On the password input screen that appears, enter the password. • The initial default password is “admin”. 19 4. Click the [Login] button. • This logs in to the System Admin page and displays the Status screen. Note For security reasons, be sure to change the password you use to log in to System Admin page from the default. For more information, see “To change the System Admin login password” (page 32). To log out of the projector’s System Admin page Click “Logout” in the upper right corner of the System Admin page. This returns to the top System Admin screen. 20 To configure security settings 1. Perform the procedure under “To log in to the projector’s System Admin page” (page 19) to log into System Admin. 2. Click “Setup” to display the System Admin page Setup screen. • Changing only the three settings enclosed in the boxes above are required to configure security settings. Do not change the settings of any other items on the screen at this time. • For details about the other settings and other System Admin operations, see “System Admin Page Operations and Settings” (page 32). 3. Enter the SSID. • Enter any characters, up to 24 characters in total, into the “SSID” input box. However, do not use “_default1”, “_default2”, or “_default3”, because these are already used for projector default SSIDs. 4. Select the security protocol. • Click the [.] button to the right of the “Security” box and select the desired security protocol from the list that appears. The following explains the meaning of each option in the list. Security It means this: WPA-PSK TKIP Performs communication encryption using WPA-PSK protocol. TKIP and AES are encryption protocols. WPA (Wi-Fi Protected Access) is a security function for encrypting communication data. WPA uses an automatically generated encryption key that is changed at preset intervals, which provides stronger security than WEP. WPA-PSK AES WPA2-PSK TKIP Performs communication encryption using WPA2-PSK protocol. TKIP and AES are encryption protocols. WPA2 is a new standard of WPA. WPA2-PSK AES WEP ASCII 64bit Performs communication encryption using WEP protocol. ASCII 64bit, ASCII 128bit, Hex 64bit, and Hex 128bit are formats for the WEP key character string entered in step 5. WEP (Wired Equivalent Privacy) is a security function that uses a character string called a “WEP key” to encrypt data and protect against unauthorized access to wireless communications. WEP ASCII...
