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.

•Turn off administrative access over wireless if possible. If you do this, you need to connect to the router with a wired Ethernet connection when you want to make configuration changes.

•Turn off remote administrative access over the Internet on your router, if possible. You can use Remote Desktop to make an encrypted connection to a computer running behind your router and make configuration changes from the local computer you are accessing over the Internet.

•To avoid accidentally connecting to another party's wireless network, turn off the setting to automatically connect to non-preferred networks. This is disabled by default in Windows XP.
