To
use the projector over a wireless network, install the Epson
802.11b/g/n wireless LAN module in the projector
(EX5280/EX9230). Do not install any other type of
wireless module.
Note: The
wireless LAN module is not included with your projector and is
optional.
Note: You do
not need the wireless LAN module for the EX7280/EX9240 since the wireless functionality is
built-in.
