Encryption Setting Description
WPA Version Your options are WPA, WPA2 or WPA Auto.
• WPA is the recommended default for best
compatibility. WPA-capable PDAs and
other devices are usually limited to WPA +
TKIP.
• WPA2 is an advanced option that provides
enhanced security, but may not be
compatible with older wireless devices.
WPA2 support on Windows XP requires a
Microsoft patch and is only available on
recent operating systems, including
Windows XP Service Pack 2 and later.
• WPA-Auto allows the client to decide
whether to use WPA or WPA2 based on the
client’s capabilities.
WPA Authentication • PSK mode is suitable for home or small
office networks.
• 802.1X mode uses a RADIUS server to
verify user identity.
• Auto mode allows the client to
authenticate based on either a passphrase
or its RADIUS credentials.
WPA Algorithm • TKIP: This algorithm provides greater
compatibility with older client devices, but
is not supported by the 802.11n standard.
Therefore, if you select TKIP encryption,
11n devices will be limited to 11g transfer
rates.
• AES: This algorithm provides enhanced
security over TKIP, and is the only
encryption algorithm supported by the
802.11i standard.
• Auto: Automatically selects TKIP or AES
based on the client’s capabilities.
Passphrase
Enter a new passphrase between 8 and 32
characters long, using any combination of
printable characters (letters, numbers,
hyphens and underscores).
