Types of wireless networks
Networks can operate in one of two modes: infrastructure or ad hoc. Lexmark recommends setting up a network in
infrastructure mode using the installation CD that came with the printer.
A wireless network where each device communicates with others through a wireless access point (wireless router)
is set up in infrastructure mode. All devices must have valid IP addresses and share the same SSID and channel.
In addition, they must share the same SSID and channel as the wireless access point (wireless router).
A simple type of wireless network is one where a PC with a wireless adapter communicates directly with a printer
equipped for wireless networking. This mode of communication is called
ad hoc
. A device in this type of network
must have a valid IP address and be set to ad hoc mode. The wireless print server must also be configured with the
same SSID and channel.
