ZyAIR G-110 User's Guide Figure 2-10 Wireless LAN Security Levels Configure the wireless LAN security using the Security Configuration screen. If you do not enable any wireless security on your ZyAIR, communication between the ZyAIR and the wired network is accessible to any wireless networking device that is in the coverage area. Make sure the security settings are the same on the ZyAIR and the intermediary AP and/or your network security server device. 2.8.1 Data Encryption with WEP WEP (Wired Equivalent Privacy) encryption scrambles all communication transmitted between the ZyAIR and the AP or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption. There are two ways to create WEP keys in your ZyAIR. • Automatic WEP key generation based on a "password phrase" called a passphrase. The passphrase is case sensitive and only available when you select the HEX key type. You must use the same passphrase for all WLAN adapters with this feature in the same WLAN. For WLAN adapters without the passphrase feature, you can still take advantage of this feature by writing down the four automatically generated WEP keys from the Security Configuration screen of the ZyAIR Utility and entering them manually as the WEP keys in the other WLAN adapter(s). • Enter the WEP keys manually. Your ZyAIR allows you to configure up to four 64-bit or 128-bit WEP keys. You must enter four keys but only one key is used as the default key at any one time. 2-12 Using the ZyAIR Utility
