Configuring WEP and WPA Encryption
WEP Encryption Settings
Open-system authentication is the only method required by 802.11b. In open-system authentication,
the SonicWALL allows the wireless client access without verifying its identity.
Shared-key authentication uses WEP and requires a shared key to be distributed to wireless clients
before authentication is allowed.
The TZ 50 Wireless/TZ 150 Wireless/TZ 170 Wireless provides the option of using Open System,
Shared Key, or both when WEP is used to encrypt data.
If Both Open System & Shared Key is selected, the Default Key assignments are not important as
long as the identical keys are used each field. If Shared Key is selected, then the key assignment is
important.
To configure WEP on the SonicWALL, log into the SonicWALL and click Wireless, then WEP
Encryption.
1
Select the authentication type from the Authentication Type list. Both (Open System & Shared
Key) is selected by default.
2
Select 64-bit or 128-bit from the WEP Key Mode. 128-bit is considered more secure than 64-bit.
This value is applied to all keys.

WPA Encryption Settings
WPA supports two protocols for storing and generating keys:
• Extensible Authentication Protocol (EAP): EAP allows WPA to synchronize keys with an external
RADIUS server. The keys are updated periodically based on time or number of packets. Use EAP
in larger, enterprise-like deployments where you have an existing RADIUS framework.
• Pre-Shared Key (PSK): PSK allows WPA to generate keys from a pre-shared passphrase that you
configure. The keys are updated periodically based on time or number of packets. Use PSK in
smaller deployments where you do not have a RADIUS server.
Note: WPA support is only available in Access Point Mode. WPA support is not available in Bridge
Mode.
