To add hardware addresses to a Wireless Access Point (WAP)
MAC filtering is a security feature in which a Wireless Access Point (WAP) is configured with a
list of MAC addresses (also called “hardware addresses”) of devices that are allowed to gain
access to the network through the WAP.
If the WAP does not have the hardware address of a device attempting to access the network,
the WAP denies the device access to the network.
If the WAP filters MAC addresses, then the printer's MAC address must be added to the
WAP's list of accepted MAC addresses.
1 Print a configuration page. (See Understanding the configuration page.)
2 Open the WAP's configuration utility, then add the printer's hardware address to the list of
accepted MAC addresses.
Reducing interference in a wireless network
The following tips will help reduce the chances for interference in a wireless network:
z 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.
z Keep the wireless devices away from large masonry structures and other building
structures as these objects can absorb radio waves and lower signal strength.
z For an infrastructure network, position the WAP in a central location in line of sight with the
wireless devices on the network.
z Keep all wireless devices on the network within range of one another.
