1 Introducing the ZyAIR
The ZyAIR B-G2000 is a broadband sharing gateway with a built-in wireless LAN access point and fourport 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), firewall, remote management and UPnP. See your User’s Guide for more details
on all ZyAIR features.
You should have an Internet account already set up and have been given most of the following information.

3 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 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
Up Your Computer’s IP Address appendix in the User’s Guide for configuring the IP address in other
operating systems.

connection. Therefore you’ll also need a
username and password and possibly
the PPPoE service name.
Your ISP will give you all needed
information.
Choose PPTP if your service provider
uses a DSL terminator with PPTP login.
The ZyAIR must have a static IP address
in this case. You’ll also need a login
name, associated password, the DSL
terminator IP address and possibly a
connection ID.

5 Hardware Installation
5.1 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.
15
ZyAIR G-2000 802.11g Wireless 4-port Router
Make sure the antennas are securely screwed onto the antenna connectors.
Figure 1 Attaching Antenna
5.2 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.
With the Desktop Holder
16
ZyAIR G-2000 802.11g Wireless 4-port Router
The included desktop holder helps you organize the ZyAIR’s connection cables.
1. Secure the desktop holder to the back of the ZyAIR with the included screw.
2. Turn the desktop holder up to the right.
3. Refer to the Hardware Connections section. Connect the cables to the ports on the ZyAIR
through the desktop holder.
4. Turn the desktop holder down and place the unit on a flat, sturdy surface (on a desk or shelf).
Figure 2 Instructions using the Desktop Holder
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. Use screws with 6mm ~7.5mm (0.24" ~ 0.30") wide heads. Connect two screws (not included)
in the wall 80mm (3.15") apart. Do not screw the screws all the way into the wall. Leave a small
gap between the head of the screws and the wall.
17
ZyAIR G-2000 802.11g Wireless 4-port Router
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. Align the holes on the back of the ZyAIR with the screws on the wall. Hang the ZyAIR on the
screws.

Make sure you are using the correct power adaptor and the power adaptor is plugged
into an adequate power supply.
this case, you should contact your vendor.
Check the cable connection to the ZyAIR LAN port.
Make sure your computer’s network card is working properly.
Turn the ZyAIR off and on. If the error persists, you may have a hardware problem. In
this case, you should contact your vendor.
Make sure the IP addresses and subnet masks of the ZyAIR and the computer are in
the same IP address range. (For example, if the ZyAIR is using the default IP address
and subnet mask, check that the IP address of the computer is in the range
192.168.1.2 ~192.168.1.254 and the subnet mask is 255.255.255.0). Refer to the
Setting Up Your Computer’s IP Address section.
If you change the ZyAIR default IP address, then enter the new IP address as the
web site address.
The default password is “1234”. If you have changed the password and have now
forgotten it, you will need to reset the ZyAIR. Refer to the User’s Guide for how to use
the RESET button.
If all of the LAN LEDs are off, check the cables between the ZyAIR and your
computer or hub.
Verify that the IP address and the subnet mask of the ZyAIR and the computers are
on the same IP address range.
The WAN IP is provided after the ISP verifies the MAC address, host name or user
ID.
Find out the verification method used by your ISP and configure the corresponding
fields.
Make sure the ZyAIR is turned on and connected to the network.
Make sure you entered your username correctly. A username may be case-sensitive.
