For Wireless LAN
Is the computer's wireless LAN broadcast strength set
to low?
Does the wireless LAN conform to 802.11g, 802.11b,
or 802.11a?
Is the firewall turned off, or has the firewall been
registered as an exception?
For Wireless LAN
Check that the supplied wireless LAN unit is securely connected.
While the configuration menu is displayed, network connection becomes invalid. Close the configuration
menu and return to the EasyMP standby screen.
Check that LAN is valid by checking "Control Panel" -"System" in the device manager and so on.
Set a different SSID. See the projector User's Guide for more information.
Turn OFF the "DHCP" setting for "Wired LAN" from the configuration menu. See the projector User's Guide
for more information.
If the computer has multiple LAN environments, it cannot connect unless the network adapter is selected
correctly. When using a computer running Windows, start EMP NS Connection, and select the network
adapter you are using from "Set Options" -"Switch LAN". s
Enable the wireless LAN.
Sometimes interference 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 communication.
Set the broadcast strength to maximum.
The wireless LAN unit 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 EMP NS Connection are "3620", "3621", and "3629".
