Chapter 2 Wireless LAN Network

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.

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.

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.

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.
