HP Deskjet 6800 series printer Reducing interference in a wireless network The following tips will help reduce the chances for interference in a wireless network: • Keep the wireless devices away from large metal objects, such as filing cabinets, and other electromagnetic devices, such as microwaves and cordless telephones, as these objects can disrupt radio signals. • Keep the wireless devices away from large masonry structures and other building structures as these objects can absorb radio waves and lower signal strength. • For an infrastructure network, position the WAP in a central location in line of sight with the wireless devices on the network. • Keep all wireless devices on the network within range of one another. Wireless network examples To see some examples of wireless networks, see the wireless network examples page. Communication modes There are two types of communication modes for wireless devices: • Infrastructure mode • Ad hoc mode Infrastructure mode When the printer is set to the infrastructure communication mode, the printer communicates with other devices on the network, whether the devices are wired or wireless, through a Wireless Access Point (WAP). WAPs commonly act as routers or gateways on small networks. 18
