Chapter 1 Getting to Know Your ZyAIR

The 10/100 Mbps Ethernet WAN port attaches to the Internet via broadband modem or router. 

The ZyAIR reset button is built into the side panel. Use this button to restore the factory 
default password to 1234; IP address to 192.168.1.1, subnet mask to 255.255.255.0 and DHCP 
server enabled with a pool of 32 IP addresses starting at 192.168.1.33.  . 

The blue ZyAIR LED (also known as the Breathing LED) is on when the ZyAIR is on and 
blinks (or breaths) when data is being transmitted to/from its wireless stations. You may use 
the web configurator to turn this LED off even when the ZyAIR is on and data is being 
transmitted/received.

The ZyAIR has a built-in RADIUS server that can authenticate wireless clients or other AP’s 
in other wireless networks.The ZyAIR can also function as an AP and as a RADIUS server at 
the same time.

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

The ZyAIR complies with the 802.11b wireless standard.

The 802.11b data rate and corresponding modulation techniques are shown in the table below. 
The modulation technique defines how bits are encoded onto radio waves.
