Chapter 8 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 This section contains the following topics: • 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. Other guidelines To keep the wireless network secure, follow these guidelines: • Use a password with at least 20 random characters. You can use up to 63 characters in a WPA password. • Avoid any common words or phrases, easy sequences of characters (such as all 1s), and personally-identifiable information for passwords. Always use random strings composed of uppercase and lowercase letters, numbers, and if allowed, special characters such as punctuation. • Change the password periodically. • Change the default password provided by the manufacturer for administrator access to the access point or wireless router. Some routers let you change the administrator name as well. • Place the access point or router in the center of a room and not near a window. 116 Configure and manage

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

This section contains the following topics:

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.

Print the network configuration page. For information on the network configuration

page, see

Understand

the

network

configuration

page

Open the WAP's configuration utility, and add the device's hardware address to the

list of accepted MAC addresses.

Other guidelines

To keep the wireless network secure, follow these guidelines:

•

Use a password with at least 20 random characters. You can use up to 63

characters in a WPA password.

•

Avoid any common words or phrases, easy sequences of characters (such as all

1s), and personally-identifiable information for passwords. Always use random

strings composed of uppercase and lowercase letters, numbers, and if allowed,

special characters such as punctuation.

•

Change the password periodically.

•

Change the default password provided by the manufacturer for administrator

access to the access point or wireless router. Some routers let you change the

administrator name as well.

•

Place the access point or router in the center of a room and not near a window.
