Configuring WEP (Wired Equivalent Privacy) Wireless Security
To configure WEP data encryption:
1. Log in to the gateway using its default address of http://192.168.0.1 or at whatever IP address
the unit is currently configured. Use the default user name of admin and default password of
password, or the password you have set up.
2. In the main menu, under Setup, select Wireless Settings.
Security Options
(continued)
• WEP (Wired Equivalent
Privacy) 64-bit encryption
• WEP (Wired Equivalent
Privacy) 128-bit encryption
WEP security uses encryption keys.
Wired Equivalent Privacy (WEP) data encryption
provides data security. WEP Shared Key authentication
and WEP data encryption will block all but the most
determined eavesdropper.
You can select 64-bit or 128-bit encryption. See
“Configuring WEP (Wired Equivalent Privacy) Wireless
Security” on page 2-6.
•WPA
• WPA-PSK (Wi-Fi
Protected Access Pre-
Shared Key)
•WPA2
• WPA2-PSK (Wi-Fi
Protected Access 2 Pre-
Shared Key)
Wi-Fi Protected Access (WPA) data encryption provides
data security. The very strong authentication along with
dynamic per frame rekeying of WPA make it virtually
impossible to compromise. Because this is a new
standard, wireless device driver and software availability
may be limited.
WPA uses the TKIP encryption type and a
pre-shared key passphrase
WPA-PSK uses the TKIP encryption type with
authentication from a RADIUS server.
WPA2 uses the AES encryption type and a
pre-shared key passphrase.
WPA2-PSK uses the AES encryption type with
authentication from a RADIUS server.
For more information about WPA, see “Configuring WPA
or WPA2 Wireless Security” on page 2-8.
Note: If you use a wireless computer to configure wireless security settings, you will be
disconnected when you click Apply. Reconfigure your wireless computer to match
the new settings, or access the gateway from a wired computer to make further
changes.
