1 Introducing the ZyAIR
The ZyAIR G-3000 is a wireless access point with two WLAN interfaces that are compliant with both
IEEE802.11g and IEEE802.11b standards. It is suitable for wireless connections to the wired network in
small office environments and businesses. The key features of the ZyAIR are the dual WLAN interface,
internal RADIUS server, PoE (Power over Ethernet), wireless security, and WDS (Wireless Distribution
System). See your User’s Guide for more details on all ZyAIR features. To view a product’s
certification(s):
1. Go to www.zyxel.com.
2. Select your product from the drop-down list box on the ZyXEL home page to go to that product's page.
3. Select the certification you wish to view from this page.

LABEL DESCRIPTION
CONSOLE Only connect this port if you want to configure the ZyAIR using the SMT (System
Management Terminal) via console port; see your User’s Guide for details.
Connect PS/2 end of the console cable to the console port of the ZyAIR and the other
end to a serial port (COM1, COM2 or other COM port) on your computer. Your computer
should have a terminal emulation communications program (such as HyperTerminal) set
to VT100 terminal emulation, no parity, 8 data bits, 1 stop bit, no flow control and 9600
bps port speed.
ETHERNET Use an Ethernet cable to connect a computer (with an Ethernet card) or switch to the
ETHERNET port. The port is auto-negotiating (can connect at 10 or 100Mbps) and auto-
crossover (automatically adjusts to the type of Ethernet cable you use (straight-through
or crossover)).
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 192.168.1.2). Refer
to the User’s Guide.
POWER
12VDC
Connect the end of the included power adaptor to this power socket. You only need to
connect the external power adaptor if you are not using PoE. If you simultaneously use
both PoE and the external power adaptor, the ZyAIR will draw power from the PoE
connection only.
Use only the included power adaptor.
EXTENSION
CARD SLOT
This slot allows you to add an IEEE802.11g or IEEE802.11b WLAN card adaptor. You
must have a WLAN card inserted before you can configure it.
The ZyAIR also contains a built-in wireless card.
2.2 The LED Display
When the power is connected the PWR, ZyAIR,SYS,WLAN LEDs turn on in that order. The ETHN
LED turns on, if the ETHERNET port is properly connected. See the ZyAIR Front Panel LED Description
table for more information.

your wired LAN. Refer to your User’s Guide for more background information.
1. Click WIZARD SETUP in the main menu to display the first wizard screen shown next.
System Name is a unique name
to identify the ZyAIR. Enter a
descriptive name.
Enter a Domain Name if your
ISP requires a domain name for
authentication; otherwise leave it
blank. Click Next to continue
2. Use the second wizard screen to set up the wireless LAN.
The WLAN Adapter field is only
available when you have an
external wireless card inserted in
the ZyAIR. Select Built-in to use
the internal WLAN card.
Name (SSID) is a unique name
to identify the ZyAIR in the
wireless LAN. Enter a descriptive
name.
A channel is the range of radio
frequencies used by IEEE
802.11b and 802.11g wireless
devices.
Click Scan to have the ZyAIR
automatically select a channel.
The selected channel
automatically appears in the
Channel ID field.

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network. Select either 64-
bit or 128-bit from the WEP Encryption drop-down list box to activate WEP encryption. Select Disable to turn off
WEP data encryption.
Select ASCII or HEX WEP key input method and then follow the on-screen instructions to set up the WEP keys.
Click Next to continue.
The wireless stations and ZyAIR must use the same Name (SSID), channel
ID and WEP encryption key (if WEP is enabled) for wireless
communication.
3. Fill in the fields in the last wizard configuration screen.
Select Get automatically from
DHCP to have the ZyAIR obtain
an IP address from a DHCP
server.
You must know the IP address
assigned to the ZyAIR (by the
DHCP server) to access the
ZyAIR again.
Select Use fixed IP address to
give the ZyAIR a fixed, unique IP
address. Enter a subnet mask
appropriate to your network and
the gateway IP address if
applicable.
Click Finish.
If you change the ZyAIR’s IP address, you must use the new IP address
if you want to access the web configurator again.
Change the wireless parameter settings in the wireless stations to match those of the ZyAIR. Refer to the
User’s Guide for your wireless adapter.

6 Hardware Installation
6.1 Attaching Antennas
Follow the steps below to connect the supplied antennas.
1. Locate the antenna connectors on the sides of your ZyAIR.
2. Screw the antennas clockwise onto the antenna connectors. The antennas should be perpendicular
to the ground and parallel to each other.
Make sure the antennas are securely screwed onto the antenna
connectors.
Figure 8 Attaching Antennas
6.2 Hardware Mounting Installation
In general, the best location for the access point is at the center of your intended wireless coverage area. For
better performance, mount the ZyAIR high up free of obstructions.
Free-standing
Place your ZyAIR on a flat, level surface (on a desk or shelf) that is strong enough to support the weight of
the ZyAIR with connection cables.
Follow the steps to position your ZyAIR on a level surface. You can use the diagrams below for
instructions on how to do this.

ZyAIR G-3000 Quick Start Guide

1. Connect the screw (included) to the support holder.
2. Connect the support holder to the ZyAIR but do not tighten the screw.
3. Twist the support holder to the side.
4. Run the connection wires through the gap in the support holder
Figure 9 Support Holder Connections
5. Twist the support holder back to the vertical position and tighten the screw that connects the
support holder to the ZyAIR.
Figure 10 Support Holder Connection Pass Through
Wall-mounted
Follow the steps to attach your ZyAIR to a wall.
1. Locate a high position on the wall that is free of obstructions.
2. Connect two screws (not included) in the wall 80mm apart. You can use the diagram at the end of
this guide to help you mark the screw holes correctly. Use screws with 6mm ~ 8mm (0.24" ~
0.31") wide heads.

ZyAIR G-3000 Quick Start Guide

Make sure the screws are securely fixed to the wall and strong enough to
hold the weight of the ZyAIR with the connection cables.
3. Adjust the cables.
4. Align the holes on the back of the ZyAIR with the screws on the wall. Hang the ZyAIR on the
screws.

7 Troubleshooting
Make sure you are using the correct power adaptor and the power adaptor is plugged into an appropriate
power supply.
PROBLEM CORRECTIVE ACTION
The PWR LED is
off.
Make sure you are using the correct power adaptor and the power adaptor is
plugged into an appropriate power supply.
Unplug the power adaptor and plug it in again. If the error persists you should
contact your vendor.
The BDG/RPT
LED is off.
If the LED is off then maybe the ZyAIR is set up to communicate in Access Point
mode and is not in AP+Bridge mode or Bridge/Repeater mode.
Make sure that the access point and the associated computers are turned on and
working properly.
Move your computer closer to the access point or the peer computer(s) within the
transmission range.
The ZyAIR LED
is off.
Unplug the power adaptor and plug it in again. If the error persists, you may have a
hardware problem. In this case, you should contact your vendor.
Make sure that the access point and the associated computers are turned on and
working properly.
Move your computer closer to the access point or the peer computer(s) within the
transmission range.
The WLAN LED
is off.
There is too much radio interference (for example microwave or another access
point) around your wireless network. Relocate or reduce the radio interference.
Optimize the performance of the WLAN by ensuring that the distance between
access points is not too far. In most buildings, most WLAN adapters operate within a
range of 100 ~ 300 feet, depending on the thickness and structure of the walls.
Radio waves can pass through walls and glass but not metal. If there is interference
in transmitting through a wall, it may be that the wall has reinforcing metal in its
structure. Install another access point to circumvent this problem.
Floors usually have metal girders and metal reinforcing struts that interfere with
WLAN transmission.
The ETHN LED is
off.
Check the wired connection between the ZyAIR ETHERNET port and your computer
or hub.
Make sure your computer’s network card is working properly.
