WEP Configuration Options

The WEP settings must match on all 802.11 devices that are within the same wireless network as

identified by the SSID. In general, if your mobile clients will roam between access points, then all

of the 802.11 access points and all of the 802.11 client adapters on the network must have the same

WEP settings.

Note: Whatever keys you enter for an AP, you must also enter the same keys for the client adapter

in the same order. In other words, WEP key 1 on the AP must match WEP key 1 on the client

adapter, WEP key 2 on the AP must match WEP key 2 on the client adapter, etc.

Note: The AP and the client adapters can have different default WEP Keys as long as the keys are

in the same order. In other words, the AP can use WEP key 2 as its default key to transmit while a

client adapter can use WEP key 3 as its default key to transmit. The two devices will communicate

as long as the AP’s WEP key 2 is the same as the client’s WEP key 2 and the AP’s WEP key 3 is

the same as the client’s WEP key 3.

WPA Wireless Security

Wi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security

enhancements that increase the level of data protection and access control for existing and future

wireless LAN systems.

The IEEE introduced the WEP as an optional security measure to secure 802.11b (Wi-Fi) WLANs,

but inherent weaknesses in the standard soon became obvious. In response to this situation, the

Wi-Fi Alliance announced a new security architecture in October 2002 that remedies the short

comings of WEP. This standard, formerly known as Safe Secure Network (SSN), is designed to

work with existing 802.11 products and offers forward compatibility with 802.11i, the new

wireless security architecture being defined in the IEEE.

WPA offers the following benefits:

• Enhanced data privacy

• Robust key management

• Data origin authentication

• Data integrity protection
