ZyAIR G-2000 Plus User’s Guide
37 Chapter 1 Getting to Know Your ZyAIR
1.2.1.4 10/100 Mbps Ethernet WAN
The 10/100 Mbps Ethernet WAN port attaches to the Internet via broadband modem or router.
1.2.1.5 Reset Button
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. .
1.2.1.6 ZyAIR LED
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.
1.2.2 Firmware Features
1.2.2.1 Internal RADIUS Server
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.
1.2.2.2 Wi-Fi Protected Access
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.
1.2.2.3 802.11b Wireless LAN Standard
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.
Table 1 IEEE 802.11b
DATA RATE (MBPS) MODULATION
1 DBPSK (Differential Binary Phase Shift Keyed)
2 DQPSK (Differential Quadrature Phase Shift Keying)
5.5 / 11 CCK (Complementary Code Keying)
