Wireless Security
This section enables you to set parameters that control how the subscriber station associates to a wireless
device and encrypts/decrypts data.
Station Wireless Security Settings
Choose the security method according to the Access Point security policy. The subscriber station should be
authorized by the Access Point in order to get access to the network and all the user data transferred
between subscriber station and Access Point will be encrypted if the wireless security methods are used.
Security: N-TRON 702-W supports all popular 802.11 security options such as WEP, WPA, and WPA2.
Select the security mode of your wireless network:
WPA – enable WPA™ security mode. Wi-Fi Protected Access - WPA™ (IEEE 802.11i/D3.0) and
WPA2™ (IEEE 802.11i) with pre-shared key management protocol offers improved security
methods as they are new protocols that were created under the 802.11i standard to address
weaknesses in the WEP approach.
WPA™ and WPA2™ support the following ciphers for data encryption:
TKIP - Temporal Key Integrity Protocol which uses the RC4 encryption algorithm.
CCMP - Counter Mode with Cipher Block Chaining Message Authentication Code Protocol which
uses the Advanced Encryption Standard (AES) algorithm.
The device will use the strongest cipher (CCMP) in Station and Access Point wireless mode by default. If
CCMP is not supported on the other side of the link, the TKIP encryption will be used. For instance, when
the device acts as an Access Point with WPA security enabled and at least one wireless station (without
CCMP support) is connected to it.
WPA-AES – enable WPA™ security mode with AES support only.
WPA2-AES – enable WPA2™ security mode with AES support only.
WPA Authentication: Choose between PSK and EAP.
PSK – Pre-shared Key – Type in the key to be shared for authentication between the AP and Station.
EAP – Extensible Authentication Protocol – Uses TTLS and MSCHAPv2 for Authentication against
an EAP authentication server
WPA Identity – For EAP only - The identity of the EAP server
WPA Username – EAP Only - Username
WPA Password – EAP Only - Password
WPA Authentication: one of the following WPA™ key selection methods should be specified if WPA™
or WPA2™ security method is used (applicable for Station and Station WDS modes only):
PSK – WPA™ or WPA2™ with Pre-shared Key method (selected by default).
