If you are using the optional wireless LAN module, make sure
■
that you have sufficient wireless signal strength (above 50
percent). On a Mac, check the AirPort icon on the Mac menu
bar. In Windows, see the documentation for your computer's
wireless card or adapter for details.
Make sure you aren't projecting one of the EasyMP Network
■
Projection screens. (You should see a message that the projector is
ready to connect.) If you have to exit a configuration screen,
restart EasyMP Network Projection.
If the projector is configured for Access Point mode and you're
■
using DHCP, allow time for your projector to appear. It takes the
server a little while to pick up the IP address.
■ If you've changed any settings for your projector or network, or
restarted your computer, allow a minute or two for the
connection to appear. If you're using AirPort, try turning AirPort
off and then on again.
■ Make sure that you're trying to connect to the right network. In
Windows, verify that you've enabled your computer's connection
to the access point or that your wireless card or adapter is enabled
and connected to the same SSID as the projector. On a Mac, click
the AirPort icon at the top of your Mac desktop to make sure
AirPort is turned on and the right network is selected.
If you have an access point or AirPort base station and you're not
■
using DHCP, check your projector's IP address on the Access
Point mode advanced settings screen. The first three segments of
the IP address should be identical to the first three segments of the
IP address of your access point or base station. The last segment of
the projector's IP address should be close, but not identical, to the
last segment of the IP address of the access point or base station.
If you're not using DHCP, check your projector's Gateway
■
address on the projector's Access Point mode advanced settings
screen. It should be identical to the IP address for your access
point or AirPort base station.
