Chapter 7:
Wireless Security
This Chapter describes how to use the MAC Filter, 802. lx, Local User Database and RADIUS
to confi gure wireless security on your WR3000 Wireless Router.
7.1 Wireless Security Overview
Wireless security is vital to your network to protect wireless communication between wireless
stations, Wireless Routers and the wired network.
The fi gure below shows the possible wireless security levels on your WR3000 Wireless
Router. The highest security level relies on EAP (Extensible Authentication Protocol) for
authentication and utilizes dynamic WEP key exchange. It requires interaction with a RADIUS
(Remote Authentication Dial-In User Service) server either on the WAN or your LAN to provide
authentication service for wireless stations.
IMPORTANT - If you do not enable any wireless security on your WR3000 Wireless
Router, your network is accessible to any wireless networking device that is within
range.
7.2 WEP Overview
WEP (Wired Equivalent Privacy) as specifi ed in the IEEE 802.11 standard provides methods
for both data encryption and wireless station authentication.
7.2.1 Data Encryption
WEP provides a mechanism for encrypting data using encryption keys. Both the AP and the
wireless stations must use the same WEP key to encrypt and decrypt data. Your WR3000
Wireless Router allows you to confi gure up to four 64-bit or 128-bit WEP keys, but only one
key can be enabled at any one time.
