Setting Up the Access Point
Caution! Shared Key mode is seriously flawed, in that it utilizes the static WEP encryp-
tion key (transmitted openly) for station authentication. This allows the WEP
encryption key to be easily discovered by anyone who might eavesdrop on the
wireless network. If static WEP is configured, it is recommended to select
Open System authentication.
• Encryption Strength: Set the length of the encryption key that will
be used. Select 64 bits or 128 bits. Note that the same size of
encryption key must be supported on all wireless stations. Default is
64 bits. 56tgb uh ik/
5. Under Security Encryption (WEP) Key, enter up to four strings of
character keys. The number of characters required updates automatically
based on how you set Authentication and Encryption Strength.

Configuring WPA-PSK (TKIP)
Wi-Fi Protected Access (WPA) is an early version of the 802.11i security
standard. Temporal key integrity protocol (TKIP) is designed for WPA to
enhance WEP.
WPA-PSK (TKIP) employs a pre-shared key (PSK), which is used for an initial
check of credentials and a 128-bit "temporal key", which combines the
station’s MAC address and a 16-octet initialization vector to produce the
encryption key. This ensures unique key encryption. TKIP uses RC4 to
perform the encryption and changes temporal keys every 10,000 packets and
distributes them, thereby greatly improving the security of the network.
To use this security profile, your wireless stations must support WPA.
Note If your wireless network has a mix of stations, some support WPA2 and others
support the original WPA, HP recommends using WPA-PSK (TKIP)/WPA2-
PSK (AES). Refer to “
Configuring WPA-PSK (TKIP) / WPA2-PSK (AES)” on
