User's Manual Part 1

WPA is an upgrade to the WEP standard for securing your wireless network. If you would like to
secure your wireless network using WPA, you must have WPA support for your wireless clients.
If you are using a Dell Wireless wireless client, you can check for the availability of
WPA-enabled software update for your wireless client at http://support.dell.com.
There are two options for network authentication (a) Pre-shared key or (b) 802.1x . Typically, in
enterprises, WPA will be used in conjunction with a RADIUS authentication server. In a Small
Office/Home Office (SOHO) environment, where there is no authentication server, users can
use pre-shared key (PSK) mode in place of the authentication server
The Dell Wireless 4350 Small Network Access Point offers both WPA running in PSK mode and
WPA with 802.1x authentication.
WPA Pre-shared Key
WPA Pre-Shared Key (PSK) is a field where the password is entered. All wireless clients must
also use this password to gain access to the network. Note that the Key format must also match
the setting for the wireless clients.
Key Format
Key Format is a box that lists 2 items: Hexadecimal Digits (numbers 0 through 9 and letters A
through F) and ASCII Characters (any letter, number, or symbol). Select the proper format for
your key. If your wireless client(s) only support one of the two formats, be sure to specify the
correct one.
WPA Group Rekey Interval
WPA Group Rekey Interval is used to specify the frequency of encryption key rotations. The
lower the number, the faster your encryption key will rotate, however, setting this number too
low may cause your wireless network to slow down.
WPA Encryption
WPA Encryption has 2 choices: TKIP (Temporal Key Integrity Protocol) is the most commonly
used encryption method. AES (Advanced Encryption Standard) can be used if your wireless
clients do not support TKIP.
