• 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.
• Turn on a wireless LAN.
• 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.
• 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.
• Connect to the access point to which the projector is connected.
• Turn off the firewall. If you do not want to turn it off, register the firewall
as an exception. Make the necessary settings to open the ports. The ports
used by this software are "3620", "3621", and "3629".
• 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.
• Make sure you start the software in the connection mode that you set on
the projector. If you cannot select or change the connection mode, select
Display Connection Mode Selection window on startup on the General
settings tab in the Set options screen. The select connection mode screen
is displayed after restarting the software.
• Make sure the projector supports the Epson iProjection version being
used. Install Epson iProjection from the EPSON Projector Software CD-
ROM supplied with the projector (if available) or download it from the
Epson Web site.
• Install the latest version of Epson iProjection on all computers. The
maximum number of computer connections and the availability of the
moderator function varies depending on the projector model, no matter
which version of Epson iProjection you are using.
• When another user is already connected, you can only connect to
projectors in the same mirroring group as that selected by the other user.
Select a projector from the same mirroring group as the user who is
already connected, or select a projector that is in standby status.
