• 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.

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.
In infrastructure mode, the printer automatically detects whether the wireless
network uses 802.11b or 802.11g.
Ad hoc mode
When the printer is set to the ad hoc, or computer-to-computer, communication
mode, the printer communicates directly with other wireless devices on the network
without the use of a WAP .
