Changes to Wireless Network Adapters
Wireless network adapters must have their firmware updated to support the following:
• The new WPA information element
Wireless clients must be able to process the WPA information element and respond with a
specific security configuration.
• The WPA two-phase authentication
Open system, then 802.1x (EAP or preshared key).
• TKIP
• Michael
• AES (optional)
To upgrade your wireless network adapters to support WPA, obtain a WPA update from your
wireless network adapter vendor and update the wireless network adapter driver.
For Windows wireless clients, you must obtain an updated network adapter driver that supports
WPA. For wireless network adapter drivers that are compatible with Windows XP (Service Pack 1)
and Windows Server 2003, the updated network adapter driver must be able to pass the adapter's
WPA capabilities and security configuration to the Wireless Zero Configuration service.
Microsoft has worked with many wireless vendors to embed the WPA firmware update in the
wireless adapter driver. So, to update you Windows wireless client, all you have to do is obtain the
new WPA-compatible driver and install the driver. The firmware is automatically updated when
the wireless network adapter driver is loaded in Windows.
Changes to Wireless Client Programs
Wireless client programs must be updated to permit the configuration of WPA authentication (and
preshared key) and the new WPA encryption algorithms (TKIP and the optional AES component).
To obtain the Microsoft WPA client program, visit the Microsoft Web site.
