1 Introducing the ZyAIR
The ZyAIR Hot Spot Gateway combines an IEEE 802.11g wireless access point, router, 4-port
switch and service gateway in one box. If you have an “exclusive printer”, you can connect it
directly to the ZyAIR, allowing you to easily print subscriber statements. The ZyAIR is ideal for
offices, coffee shops, libraries, hotels and airport terminals catering to subscribers that seek Internet
access. You should have an Internet account already set up and have been given usernames,
passwords etc. required for Internet access.
1.1 Safety Warnings

LABEL DESCRIPTION
PRINTER Use the printer cable to connect an “exclusive printer” to this port.
LAN 1-4 These ports are auto-crossover, (”auto MDI/MDI-X”) which means you can use either a
straight-through or crossover Ethernet cable to connect the ZyAIR to a computer or a hub.
WAN Connect your broadband modem to this port with the Ethernet 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, LAN IP address 192.168.1.1).
POWER 5VDC After you’ve made the above connections, connect the ZyAIR’s included power adaptor to
the ZyAIR’s power socket. Use only the included power adaptor. The PWR LED turns on.
The LAN and WAN LEDs flash and then turn on if they have proper connections. The
ZyAIR LED turns on for 20 seconds and then turns off. The SYS LED turns on. The ZyAIR
LED turns back on and blinks if the wireless connection is active.

address. This is the default for most new computers.
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.
Your computer must have an Ethernet 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.
2.1 Windows 2000/NT/XP

address, click Obtain an IP address automatically.
If you know your DNS sever IP address(es), type them
in the Preferred DNS server and/or Alternate DNS
server fields.
-To configure a static IP address, click Use the
following IP Address and fill in the IP address
(choose one from 192.168.1.2 to 192.168.1.254),
Subnet mask (255.255.255.0), and Default gateway
(192.168.1.1) fields.
Then enter your DNS server IP address(es) in the

3 Configuring Your ZyAIR
This guide shows you how to use the web configurator for initial
configuration. See your User’s Guide for background information on all
other ZyAIR features.
3.1 Accessing Your ZyAIR Via Web Configurator
1. Your web browser must have JavaScript support enabled. Launch your web browser. Enter
“192.168.1.1” as the web site address.
Figure 3 Entering ZyAIR LAN IP Address in Internet Explorer
2. A login screen displays. Enter the user name (“admin” is the default), password (“1234” is the
default) and click Getting Started. The user name is case sensitive, so enter “admin” exactly as
shown. If you make an incorrect entry, refresh your browser and try again. Only one
administrator can log in at one time. The ZyAIR logs you out after five minutes of no
management using the web configurator, so you then have to log in again.

3.2 Internet Connection Wizard
The Wizard Setup screens appear by default after login only the first time you access the ZyAIR and
run the wizard. After that, the SYSTEM QUICK VIEW screen appears after login.
1. The first Wizard screen displays after your initial login. This first screen varies depending on the
type of Internet connection you use.
Figure 5 Internet Connection: DHCP Client
Select DHCP Client if your ISP did not assign
you a fixed IP address. Your ISP assigns the
