Connection Mode, try the following solutions.
• Check the status of the external devices used for the network connection or
the environment in which the network devices and the projector are located.
• Connect the specified wireless LAN unit to the projector securely. See
your projector User's Guide for more details.

environment prevents the projector from being found in a search.
• Set the radio strength for the network devices to the maximum.
• Check the projector's network settings.
• Set the Connection Mode setting to Quick.
• Turn on a wireless LAN.
• When you enable the security setting, set the same passphrase to the

wireless LAN card on your computer.
• Enable the wireless LAN setting or AirPort on your computer.
• Check the software settings.

Solutions When You Cannot Connect Projectors Using
Advanced Connection Mode (Wireless)
When you cannot connect the computer and the projector using Advanced
Connection Mode over a wireless network, try the following solutions. If you
cannot resolve the problem, contact your network administrator.
• Check the status of the external devices used for the network connection or
the environment in which the network devices and the projector are located.
• Connect the specified wireless LAN unit to the projector securely. See
your projector User's Guide for more details.
• Check for any obstacles between the access point and the computer or
projector, and change their position to improve communication.
Sometimes, indoor environments prevent the projector from being found
in a search.
• Make sure that the access point and the computer or projector are not too
far apart. Move them closer together and try to connect again.
• If the wireless connection is slow or your projected image contains noise,
check for interference from other equipment, such as a Bluetooth device
or microwave. Move the interfering device farther away or expand your
wireless bandwidth.
• Set the radio strength for the network devices to the maximum.
• Set the IP address, the subnet mask, and the gateway address for the
access point correctly.
• Make sure the wireless LAN system of the access point supports the
projector's wireless LAN system.
