Chapter 1 Getting To Know Your P-660HW-D

Your ZyXEL device's compact and ventilated housing minimizes space requirements making 
it easy to position anywhere in your busy office. 

A combination of switch and router makes your ZyXEL device a cost-effective and viable 
network solution. You can connect up to four computers to the ZyXEL device without the cost 
of a hub. Use a hub to add more than four computers to your LAN.

The ZyXEL device supports the IEEE 802.11g standard, which is fully compatible with the 
IEEE 802.11b standard, meaning that you can have both IEEE 802.11b and IEEE 802.11g 
wireless clients in the same wireless network.

Note: The ZyXEL device may be prone to RF (Radio Frequency) interference from 

other 2.4 GHz devices such as microwave ovens, wireless phones, Bluetooth 
enabled devices, and other wireless LANs.

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification standard. 
Key differences between WPA and WEP are user authentication and improved data 
encryption.

WPA 2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, 
authentication and key management than WPA.

Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol 
(TKIP), Message Integrity Check (MIC) and IEEE 802.1x. In addition to TKIP, WPA2 also 
uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining 
Message authentication code Protocol (CCMP) to offer stronger encryption.

The ZyXEL device is equipped with one 3dBi fixed antenna to provide clear radio signal 
between the wireless stations and the access points. 

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless 
network to help keep network communications private.
