2.1.4 Super G

The Super G technology works with IEEE 802.11 a/b/g products. It doubles IEEE 802.11g performance by bonding two 54Mbps channels and allowing larger frames to be sent. IEEE 802.11g wireless LAN devices using Super G can transmit at up to 108 Mbps.

2.2 Wireless LAN Security Overview

Wireless LAN security is vital to your network to protect wireless communications.

Configure the wireless LAN security using the Profile Security Settings screen. If you do not enable any wireless security on your G-170S, the G-170S’s wireless communications are accessible to any wireless networking device that is in the coverage area.

2.2.1 Data Encryption with WEP

WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the G-170S 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 G-170S.

•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.

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 Settings screen of the ZyXEL utility and entering them manually as the WEP keys in the other WLAN adapter(s).

•Enter the WEP keys manually.

Your G-170S allows you to configure up to four 64-bit, 128-bit or 152-bit WEP keys and only one key is used as the default key at any one time.

2.2.2IEEE 802.1x

The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using an external RADIUS server.
