Solutions When You Cannot Connect Projectors Using Advanced Connection Mode

(Wireless)

When you cannot connect the computer and the projector using Advanced Connection Mode over a

wireless network, try the following solutions. If you cannot resolve the problem, contact your network

administrator.

• Check the status of the external devices used for the network connection or the environment in which

the network devices and the projector are located.

• Connect the specified wireless LAN unit to the projector securely.

• Check for any obstacles between the access point and the computer or projector, and change their

position to improve communication. Sometimes, indoor environments prevent the projector from

being found in a search.

• Make sure that the access point and the computer or projector are not too far apart. Move them

closer together and try to connect again.

• If the wireless connection is slow or your projected image contains noise, check for interference

from other equipment, such as a Bluetooth device or microwave. Move the interfering device farther

away or expand your wireless bandwidth.

• Set the radio strength for the network devices to the maximum.

• Set the IP address, the subnet mask, and the gateway address for the access point correctly.

• Make sure the Wireless LAN conforms to 802.11a, 802.11b, 802.11g, or 802.11n. The Wireless

LAN is not compatible with other standards such as 802.11.

• Check the projector's network settings.

• Set the Connection Mode setting to Advanced.

• Set the computer, the access point, and the projector to the same SSID.

• Set DHCP to Off. When DHCP is set to On, it may take some time to enter LAN standby status if an

available DHCP server is not found.

• Set the IP address, the subnet mask, and the gateway address for the projector correctly.

• Set Wireless LAN Power to On, or Wireless Mode to Wireless LAN On.

• Set the wireless LAN system to meet the standards supported by the access point.

• When you enable the security setting, set the same passphrase to the access point, the computer,

and the projector.

• Close network settings on the projector, and then return to the LAN standby screen.
