1 Introducing the ZyAIR
The ZyAIR Hot Spot Gateway combines an 802.11b wireless access point, router, 4-port switch and
service gateway in one box. An “exclusive printer” connects 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.

LABEL DESCRIPTION
ONE-CLICK
PRINTER
Use the printer cable to connect the included printer (“exclusive printer”) to this port.
WAN Connect your broadband modem to this port with the Ethernet cable that came with your
modem.
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.
Power 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 SYS LED blinks while performing system testing and then turns steady on if the
testing is successful. A LAN LED turns on if a LAN port is properly connected. Refer to the
following table for more detailed LED descriptions.

2 Setting Up Your Computer’s IP Address
Skip this section if your computer is already set up to accept a dynamic IP
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
1. In Windows XP, click start, Control Panel. In Windows 2000/NT, click Start, Settings, Control Panel.
2. In Windows XP, click Network Connections.
In Windows 2000/NT, click Network and Dial-up Connections.
3. Right-click Local Area Connection and then click Properties.
4. Select Internet Protocol (TCP/IP) (under the General tab in Win XP) and click Properties.
5. The Internet Protocol TCP/IP Properties screen
opens (the General tab in Windows XP).
- To have your computer assigned a dynamic IP
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 from192.168.1.2 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
Preferred DNS server and/or Alternate DNS server
fields.
If you have more than two DNS servers, click
Advanced, the DNS tab and then configure them using
Add.

6. Click Advanced. Remove any previously installed
gateways in the IP Settings tab and click OK to go back
to the Internet Protocol TCP/IP Properties screen.
7. Click OK to close the Internet Protocol (TCP/IP)
Properties window.
8. Click OK to close the Local Area Connection
Properties window.
2.2 Checking/Updating Your Computer’s IP Address
1. In the computer, click Start, (All) Programs, Accessories and then Command Prompt.
2. In the Command Prompt window, type "ipconfig" and then press ENTER to verify that your computer’s IP
address is in the correct range (192.168.1.2 to 192.168.1.255) with subnet mask 255.255.255.0. This is
necessary in order to communicate with the ZyAIR.
Refer to your User’s Guide for detailed IP address configuration for other Windows and Macintosh
computer operating systems.
2.3 Testing the Connection to the ZyAIR
1. Click Start, (All) Programs, Accessories and then Command Prompt.
2. In the Command Prompt window, type "ping” followed by a space and the IP address of the ZyAIR
(192.168.1.1 is the default).

3. Press ENTER and the following screen displays.
Your computer can now communicate with the ZyAIR using a LAN port.
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
ZyAIR’s WAN port a dynamic IP address. This is
the default selection.
Click Next to continue to Figure 9.

Figure 6 Internet Connection: Static_IP
Select Static_IP If the ISP assigned a fixed IP
address.
Enter the WAN IP address, subnet mask,
gateway IP address and DNS server address(s)
that your ISP assigned you.
Click Next to continue to Figure 9.
Figure 7 Internet Connection: PPPoE
Select PPPoE If the ISP uses PPPoE for your
account (PPPoE simulates a dial-up connection).
Enter the user name and password exactly as
your ISP assigned them.
A maximum transmission unit (MTU) is the
largest size packet or frame, specified in octets
(eight-bit bytes) that can be sent in a packet- or
frame-based network. The Transmission Control
Protocol (TCP) uses the MTU to determine the
maximum size of each packet in a transmission.
Too large an MTU size may mean
retransmissions if the packet encounters a router
that can't handle that large a packet. Too small
an MTU size means relatively more header
overhead and more acknowledgements that
have to be sent and handled.
The maximum segment size (MSS) is the largest
amount of data, specified in bytes, that a
computer or communications device can handle
in a single, unfragmented piece.
For optimum communications, the number of bytes in the data segment and the header must add up to less than
the number of bytes in the maximum transmission unit (MTU).
Enter the name of your PPPoE server, in the Service Name field if provided; otherwise leave it blank.
Select Connect on Demand when you don't want an “always-on” connection and specify an inactivity time limit
(in minutes) in the Max Idle Time field.
Select Keep Alive if you want an “always-on” connection. The Redial Period is how long the ZyAIR waits before
reconnecting in the event of a disconnect. Click Next to continue to Figure 9.

Figure 8 Internet Connection: PPTP
Select PPTP if your service provider uses a DSL
terminator with PPTP login. The ZyAIR must
have a static IP address (My IP Address) in this
case, and a subnet mask (My IP Subnet Mask)
if provided by your ISP.
Enter the DSL terminator IP address (PPTP
Server IP Address) and a username with an
associated password.
See the description of the PPPoE encapsulation
screen for information on PPP MTU, TCP MSS,
Connect On Demand and Keep alive.
If your ISP has provided a connection ID name,
enter it in the Connection ID/Name field.
Click Next to continue to Figure 9.
2. Use the second wizard screen to set up the wireless LAN.
Figure 9 Wireless Settings
ESSID is a unique name to identify the ZyAIR
in the wireless LAN. Enter a descriptive name.
Select a channel (range of radio frequencies
used by IEEE 802.11b wireless devices) from
the drop-down list box.
WEP (Wired Equivalent Privacy) encrypts
data frames before transmitting them over the
wireless network.
Select 64 Bit, 128 Bit or 256 Bit from the
WEP Encryption and enter a key of the
appropriate length to activate WEP
encryption. Select Disable to turn off WEP
data encryption.
Click Next to continue.
