Guidelines for reducing interference on 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.

Guidelines for ensuring wireless network security

•To add hardware addresses to a WAP

•Other guidelines

To add hardware addresses to a WAP

MAC filtering is a security feature in which a 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 device's MAC address must be added to the WAP's list of accepted MAC addresses.

1.Print the network configuration page. For information on the network configuration page, see Understand the network configuration page.

2.Open the WAP's configuration utility, and add the device's hardware address to the list of accepted MAC addresses.
