Networking 120 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 an access point (wireless router). In ad hoc mode, a computer with a wireless network adapter communicates directly with a printer equipped with a wireless print server. Infrastructure Ad hoc Characteristics Communication Through an access point Directly between devices Security More security options WEP or no security Range Determined by the range and number Restricted to the range of individual of access points devices on the 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 access point Yes Same channel Yes, including the access point Yes We recommend setting up a network in infrastructure mode using the installation software CD. Infrastructure mode provides: • Increased network security • Increased reliability • Faster performance • Easier setup Finding the signal strength The signal strength tells you how strongly the computer or printer is receiving the wireless signal from the wireless network. Poor signal quality could affect connectivity during configuration. Checking computer connectivity 1 From your computer system tray, click the wireless icon that corresponds to the software managing your wireless network adapter. 2 Check the signal quality.
