You should have at least a basic knowledge of TCP/IP networking concepts and topology. Related Documentation · Quick Start Guide The Quick Start Guide is designed to help you get up and running right away. It contains information on setting up your network and configuring for Internet access. [. . . ] If you do not have a RADIUS server, you cannot set up user names and passwords for your users. Unauthorized wireless devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network. The following table shows the relative effectiveness of wireless security methods:. Table 15 Wireless Security Levels SECURITY LEVEL Least Secure SECURITY TYPE Unique SSID (Default) Unique SSID with Hide SSID Enabled MAC Address Filtering WEP Encryption IEEE802. 1x EAP with RADIUS Server Authentication Wi-Fi Protected Access (WPA) Most Secure WPA2 The available security modes in your ZyXEL Device are as follows: · None. Wired Equivalent Privacy (WEP) encryption scrambles the data transmitted between the wireless stations and the access points to keep network communications private. This is a standard that extends the features of IEEE 802. 11 to support extended authentication. This provides 802. 1x-Only authentication with a static 64bit WEP key and an authentication server. This provides 802. 1x-Only authentication with a static 128bit WEP key and an authentication server. Wi-Fi Protected Access (WPA) is a subset of the IEEE 802. 11i standard. WPA2 (IEEE 802. 11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. This commands the ZyXEL Device to use either WPA2 or WPA depending on which security mode the wireless client uses. This adds a pre-shared key on top of WPA2 standard. 76 ZyXEL NWA-1100 User's Guide Chapter 7 Wireless Security Screen · WPA2-PSK-MIX. This commands the ZyXEL Device to use either WPA-PSK or WPA2-PSK depending on which security mode the wireless client uses. In Bridge and Bridge + AP operating modes, the only available security modes are WEP and WPA2-PSK. Passphrase A passphrase functions like a password. In WEP security mode, it is further converted by the ZyXEL Device into a complicated string that is referred to as the "key". This key is requested from all devices wishing to connect to a wireless network. PSK The Pre-Shared Key (PSK) is a password shared by a wireless access point and a client during a previous secure connection. The key can then be used to establish a connection between the two parties. Encryption Wireless networks can use encryption to protect the information that is sent in the wireless network. If you do not know the secret code, you cannot understand the message. The intended recipient of the data can "unlock" it with a pre-assigned key, making the information readable only to him. The ZyXEL Device when used as a wireless client employs Temporal Key Integrity Protocol (TKIP) data encryption.
