Wireless networks can operate in one of two modes: infrastructure or ad hoc. In infrastructure mode, all devices on a wireless network communicate with each other through a wireless router (wireless access point). Devices on the wireless network must have valid IP addresses for the current network and share the same SSID and channel as the wireless access point. In ad hoc mode, a computer with a wireless network adapter communicates directly with a printer equipped with a wireless print server. The computer must have a valid IP address for the current network and be set to ad hoc mode. The wireless print server must be configured to use the same SSID and channel that the computer is using. The following table compares the characteristics and requirements of the two types of wireless networks. Characteristics Infrastructure Ad hoc Communication Through wireless access point Directly between devices Security More security options WEP or no security Range Determined by range and number of Restricted to range of individual wireless access points devices on network Speed Usually faster Usually slower Requirements for all devices Unique IP address for each device Yes Yes Mode set to Infrastructure mode Ad hoc mode Same SSID Yes, including the wireless access Yes point Same channel Yes, including the wireless access Yes point We recommend setting up a network in infrastructure mode using the installation CD that came with the printer.

How are infrastructure and ad hoc networks different?
Wireless networks can operate in one of two modes: infrastructure or ad hoc.
In
infrastructure
mode, all devices on a wireless network communicate with each other through a wireless router
(wireless access point). Devices on the wireless network must have valid IP addresses for the current network and
share the same SSID and channel as the wireless access point.
In
ad hoc
mode, a computer with a wireless network adapter communicates directly with a printer equipped with a
wireless print server. The computer must have a valid IP address for the current network and be set to ad hoc mode.
The wireless print server must be configured to use the same SSID and channel that the computer is using.
The following table compares the characteristics and requirements of the two types of wireless networks.
