    • Check the status of the external devices used for the network connection or the setting environment of the projector.
      • Connect the specified wireless LAN unit to the projector securely.
      • Check for any obstacles between the computer and projector, and change their position to improve communication. Sometimes the indoor 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.

        Go to Network > Network Configuration > Wireless LAN > Connection Mode.

      • Set an SSID that is different from the SSID for the access point.

        Go to Network > Network Configuration > Wireless LAN > SSID.

      • Set DHCP to Off.

        Go to Network > Network Configuration > Wireless LAN > DHCP or Network > Network Configuration > Wireless LAN > IP Settings > DHCP.

      • Set Wireless LAN Power to On.

        Go to Network > Network Configuration > Wireless LAN > Wireless LAN Power.

      • When you enable the security setting, set the same passphrase to the computer and the projector.
      • Close network settings on the projector, and then return to the LAN standby screen.
    • Check the computer's network settings.
      • If the wireless LAN adapter is not installed on your computer, install a wireless LAN card on your computer.
      • Enable the wireless LAN setting or AirPort on your computer.
    • Check the software settings.
      • If another user has established a connection and the projected image remains as it is, you can connect by interrupting the current connection.

        If a Projector Keyword is set for the projector but you do not know the keyword, restart the projector and check the keyword displayed on the LAN standby screen.

      • If you cannot select or change the connection mode, select Display Connection Mode Selection window on startup on the General settings tab from Set options. The select connection mode screen is displayed after restarting the software.

      • Connect the specified wireless LAN unit to the projector securely.
      • 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.
    • Check the projector's network settings.
      • Set the Connection Mode setting to Advanced.
      • Set the computer, the access point, and the projector to the same SSID.
      • Set DHCP to Off. When DHCP is set to On, it may take some time to enter LAN standby status if an available DHCP server is not found.
      • Set the IP address, the subnet mask, and the gateway address for the projector correctly.
      • Set Wireless LAN Power to On, or Wireless Mode to Wireless LAN On.
      • Set the wireless LAN system to meet the standards supported by the access point.
      • When you enable the security setting, set the same passphrase to the access point, the computer, and the projector.

    • Check the access point settings.
      • Set connection permission at the access point to allow projectors to connect if any functions that block connections, such as MAC Address restrictions and port restrictions, are set to the access point.
    • Check the software settings.
      • Select the network adapter you are using from Switch LAN on the Set options screen. If the computer has multiple LAN environments, a connection cannot be established unless the network adapter is selected correctly.
      • If you cannot find the projector you want to connect to using Automatic search, select Manual search to specify the IP address.
      • If another user has established a connection and the projected image remains as it is, you can connect by interrupting the current connection.
