Wireless networks can operate in one of two modes: infrastructure or ad hoc. In infrastructure mode, all devices on a wireless network connect to 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 connects directly to a printer equipped with a wireless print server. There is no wireless router or access point in an ad hoc network. 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 Communication Infrastructure Ad hoc Through wireless access point Directly between devices Security Range More security options WEP or no security Determined by range and number Restricted to range of individual of wireless access points devices on network Speed Usually faster Usually slower Requirements for all devices Unique IP address for each device Same SSID Yes Yes Yes, including the wireless access Yes point Lexmark recommends setting up a network in infrastructure mode using the installation CD that came with the printer.
