you must be logged in as the Administrator. 
						

							158Solving Problems
■Try restarting your computer.
You can’t connect to the projector using NS Connection.
■Make sure the Epson 802.11g card is installed correctly in the 
projector; see page 48. If you have to reinstall the card, restart NS 
Connection or the program will not be able to detect the 
projector.
■Restart your computer.
■Make sure your projector and computer are configured correctly; 
see page 51 (Ad Hoc mode) or page 57 (Access Point mode).
■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 configuration 
screens. (You should see a message that the projector is ready to 
connect.) If you have to exit a configuration screen, restart 
NS Connection.
■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 (see page 63) or that your wireless card or 
adapter is enabled and its SSID is set to match the projector’s 
ESSID (see page 55). On a Mac, click the AirPort icon at the top 
of your Mac desktop to make sure AirPort is turned on and the 
projector’s ESSID or your AirPort network is selected. 
						

							Solving Problems159
■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.
■If you’re using a projector keyword, it changes each time you turn 
the projector off and then on again, or remove and reinsert the 
802.11g wireless card. Check the projector’s keyword on the 
EasyMP Network screen and enter it at the prompt.
■If you’re using AirPort, check the configuration of your network. 
Start the AirPort Admin utility, select your base station, click 
Configure and click Show All Settings. Click the Network 
tab. If you set up your projector to connect in DHCP mode, turn 
on 
Distribute IP Addresses and Share a Single IP Address. 
■If you’re using AirPort and DHCP is turned off on your 
projector’s Access Point mode advanced settings screen, make sure 
Distribute IP Addresses is off. 
■If you’re using Access Point mode and you’re connecting to the 
wrong network, you may be experiencing signal interference from 
another network. Try resetting your access point or base station, 
then restart NS Connection.
■If you’re using AirPort, the projector’s ESSID should match the 
AirPort network name, not the name of the AirPort base station. 
To check the network name, start the AirPort Admin utility, 
select your base station, and click 
Configure. Then click Show 
All Settings
. The network name appears on the AirPort tab.
■If you’re prompted for a password when you connect, enter the 
WEP encryption key (if you’re using WEP encryption).
■Try connecting using IP Connect Mode; see page 77.
