1 Introducing the ZyAIR
The ZyAIR G-2000 Plus is a broadband sharing gateway with a built-in wireless LAN access point and
four-port switch that makes it easy for people to set up a small home/office network and share Internet
access via a broadband (cable/DSL) modem. Key features of the ZyAIR include 802.1x wireless LAN
security, WPA (Wi-Fi Protected Access), internal RADIUS server, firewall, remote management and
UPnP. See your User’s Guide for more details on all ZyAIR features.

LABEL DESCRIPTION
LAN Use an Ethernet cable to connect at least one computer for initial ZyAIR configuration.
These ports are auto-negotiating (can connect at 10 or 100Mbps) and auto-crossover
(automatically adjust to the type of Ethernet cable you use (straight-through or
crossover)).
WAN Connect your cable/DSL modem to this port with the cable that came with your modem.
RESET You only need to use this button if you’ve forgotten the ZyAIR’s password. It returns the
ZyAIR to the factory defaults (password is 1234 and LAN IP address 192.168.1.1). Refer
to the User’s Guide.
After you’ve made the connections connect the power cable to a power supply and look at the front panel
LEDs.

The default IP address of the ZyAIR is 192.168.1.1
3 Set Up Your Computer’s IP Address
The ZyAIR is already set up to assign your computer an IP address. Use this section to set up your
computer to receive an IP address or assign it a static IP address in the 192.168.1.2 to 192.168.1.254 range
with a subnet mask of 255.255.255.0. This is necessary to ensure that your computer can communicate with
your ZyAIR.

192.168.1.2 and 192.168.1.254 with subnet mask 255.255.255.0.
Your computer must have a network card and TCP/IP installed. TCP/IP should already be installed on
computers using Windows NT/2000/XP, Macintosh OS 7 and later operating systems. Refer to the Setting
