Solutions
Consult with your network administrator.
Set the encryption settings of the projector
again and reconnect.
The followings are encryption methods
supported by the projector:
･ WPA2-PSK(AES)
･ WPA2-PSK(TKIP)
･ WPA-PSK(AES)
･ WPA-PSK(TKIP)
･ WEP128bit
(Available only in INFRASTRUCTURE mode)
･ WEP64bit
(Available only in INFRASTRUCTURE mode)
This projector cannot be connected to the
wireless network using the encryption methods
other than the above.
･ Put the projector close to the wireless device.
･ When the projector is near the steel door,
the radio wave may not reach to the wireless
device. In that case, keep the projector away
from the door.
･ Consult with your network administrator
because there may be an interfering wireless
device.
The USB wireless adapter (USB-WL-11N)
does not support 5GHz, but only 2.4GHz.
The same network address cannot be used
for wireless LAN and wired LAN. Set different
network address for wireless LAN and wired
LAN.
Refer to the user's manual for the computer
and enable the wireless network adapter.
