This chapter discusses how to configure wireless security on the G-162.
4.1
Wireless LAN Security
Wireless LAN security is vital to protect wireless communications.
The figure below shows the possible wireless security levels on your G-162. EAP (Extensible
Authentication Protocol) is used for authentication and utilizes dynamic WEP key exchange. It requires
interaction with a RADIUS (Remote Authentication Dial-In User Service) server either on the WAN or
your LAN to provide authentication service for wireless clients.

Configure the wireless LAN security using the

screen. If you do not enable any
wireless security on your G-162, the G-162’s wireless communications are accessible to any wireless
networking device that is in the coverage area.
4.1.1 Data Encryption with WEP
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the G-162 and
the AP or other peer wireless device to keep them private. Both the wireless clients 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 G-162.

Automatic WEP key generation based on a “password phrase” called a passphrase. The passphrase
is case sensitive. You must use the same passphrase for all WLAN adapters with this feature in the
same WLAN.
