    Reference Manual for the NETGEAR ProSafe 802.11g Wireless Access Point WG302 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, and so on.

    The Wi-Fi Alliance is now performing interoperability certification testing on Wi-Fi Protected Access products. Starting August of 2003, all new Wi-Fi certified products have to support WPA. NETGEAR is implementing WPA and WPA2 on client and access point products. The 802.11i standard was ratified in 2004.

  • Page 95 Reference Manual for the NETGEAR ProSafe 802.11g Wireless Access Point WG302 • Key management. WPA/WPA2 features a robust key generation/management system that integrates the authentication and data privacy functions. Keys are generated after successful authentication and through a subsequent 4-way handshake between the station and Access Point (AP).
  • Page 96 RADIUS infrastructure, WPA supports the use of a pre-shared key. Together, these technologies provide a framework for strong user authentication. Windows XP implements 802.1x natively, and several NETGEAR switch and wireless access point products support 802.1x. Client with a WPA/...

Information elements include the required authentication method (802.1x or Pre-shared key) and the preferred cipher suite (WEP, TKIP, or AES). Probe Responses (AP to station) and Association Requests (station to AP) also contain WPA information elements.
  • Page 98 Reference Manual for the NETGEAR ProSafe 802.11g Wireless Access Point WG302 If configured to implement dynamic key exchange, the 802.1x authentication server can return session keys to the access point along with the accept message. The access point uses the session keys to build, sign and encrypt an EAP key message that is sent to the client immediately after sending the success message.

    Product Support for WPA/WPA2 Starting in August, 2003, NETGEAR, Inc. wireless Wi-Fi certified products will support the WPA standard. NETGEAR, Inc. wireless products that had their Wi-Fi certification approved before August, 2003 will have one year to add WPA so as to maintain their Wi-Fi certification.
