Check the following:
- Make sure you’ve installed the Epson 802.11g card correctly in the projector; see Starting EasyMP. 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 Configuring the Connection: Using Ad Hoc mode or Using Access Point mode.
- Make sure that you have sufficient wireless signal strength (above 50 percent). On a Macintosh, check the AirPort icon on the Macintosh 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 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 its SSID is set to match the projector’s ESSID (for more details, see Configuring the Network Settings for Windows). On a Macintosh, click the AirPort icon at the top of your Macintosh desktop to make sure AirPort is turned on and the projector’s ESSID or your AirPort 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.
- If you’re using a projector keyword, it changes each time you turn the projector off and then on again, or if the projector is left idle for more than 5 minutes without an NS Connection session. 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 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’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.
- Try connecting using IP Connect Mode; see Connecting in IP Connect Mode.
