For Wireless LAN
Is the computer's Wireless LAN electromagnetic wave set
to low?

802.11a?
Is the firewall turned off, or has the firewall been
registered as an exception?

For Wired LAN
When the Network Configuration screen is displayed on the projector, network connection for
EasyMP Network Projection is disabled. Close network settings on the projector, and return to the
LAN standby screen.
Check that LAN is valid by checking Control Panel - System - Hardware in the device manager and so
on.
Set an SSID that is different from that of the access point. See your projector User's Guide for details.
Set the DHCP setting to Off from Wired LAN in the Configuration Menu. See your projector User's
Guide for details.
If the computer has multiple LAN environments, it cannot connect unless the network adapter is
selected correctly. When using a computer running Windows, start EasyMP Network Projection and
select the network adapter you are using from Set options - Switch LAN. s
Enable the Wireless LAN.
Sometimes the electromagnetic wave situation prevents the projector from being found in a search.
Check for any obstacles between the access point and the computer or projector, and change their
position to improve the electromagnetic wave situation.
Set the electromagnetic wave strength to maximum.
It is only compatible with standards 802.11g, 802.11b, and 802.11a, and not with other standards such
as 802.11.
When you do not wish to turn off the firewall or register the firewall as an exception, make the
necessary settings to open the ports.
The ports used by EasyMP Network Projection are "3620", "3621", and "3629".
Check that the network cable is connected correctly. Reconnect it if it is not connected or not
connected properly.
