Preface
This guide is for the networking professional who installs and manages the Ziwell
ZWA-G120 Multi-Mode AP, hereafter referred to as the “device”. To use this guide,
you should have experience working with the TCP/IP configuration and be familiar
with the concepts and terminology of wireless local area networks.

Ch 1. ZWA-G120 Installation
Packing List
Before you start to install the device, make sure the package contains the
following items：
zZWA-G120 Multi-Mode AP * 1
zPower Adapter * 1
zRJ-45 Cable * 1
Multi-Mode AP Power Adapter
RJ-45 Cable
Hardware Installation
Once you check off everything from the package, you can start to install the
device. You can use the wall mount hole on the bottom of the device to
mount the device on the wall, or just put the device on the desktop. The
administrator can refer to the figure below while constructing your WLAN
environment.

Ch 2. First Time Configuration
Before Start to Configure
There are two ways to configure the device, one is through web-browser,
and the other is through Secure Shell CLI interface. To access the
configuration interfaces, make sure you are using a computer connected to
the same network as the device. The default IP address of the device is
192.168.2.254, and the subnet-mask is 255.255.255.0.
The device has three operation modes (Router/Bridge/WISP). In bridge
mode, also known as AP Client, you can access the device by both WLAN
(Wireless Local Area Network) and wired LAN. And in router/WISP modes,
the device can be accessed by both WLAN and WAN. The default IP
addresses for the device are 192.168.2.254(for LAN), 172.1.1.1(for WAN),
so you need to make sure the IP address of your PC is in the same subnet
as the device, such as 192.168.2.X (for LAN), 172.1.1.X (for WAN).
Please note that the DHCP server inside the device is default to up and
running. Do not have multiple DHCP servers in your network environment,
otherwise it will cause abnormal situation.
We also provide an auto-discovery tool which is for finding out the IP of the
device. In case, you’ve forgot the IP of the device or the IP of the device has
been changed, you can use the tool to find out the IP of the device even your
PC is not in the same subnet as the device is.
Knowing the Network Application
ZWA-G120 can act as the following roles, and it supports WDS (Wireless
Distribution System) function.
zAccess Point
zWDS (Wireless Repeater)
zBridge/Router
zWISP
zAP Client
The device provides 3 different operation modes and the wireless radio of device
can act as AP/Client/WDS. The operation mode is about the communication
mechanism between the wired Ethernet NIC and wireless NIC, the following is the

4
types of operation mode.
Router
The wired Ethernet (WAN) port is used to connect with ADSL/Cable modem and
the wireless NIC is used for your private WLAN. The NAT is existed between the 2
NIC and all the wireless clients share the same public IP address through the WAN
port to ISP. The default IP configuration for WAN port is static IP. You can access
the web server of device through the default WAN IP address 172.1.1.1 and modify
the setting base on your ISP requirement.
Bridge
The wired Ethernet and wireless NIC are bridged together. Once the mode is
selected, all the WAN related functions will be disabled.
WISP (Wireless ISP)
This mode can let you access the AP of your wireless ISP and share the same public
IP address form your ISP to the PCs connecting with the wired Ethernet port of the
device. To use this mode, first you must set the wireless radio to be client mode and
connect to the AP of your ISP then you can configure the WAN IP configuration to
meet your ISP requirement.
The wireless radio of the device acts as the following roles.
AP (Access Point)
The wireless radio of device serves as communications “hub” for wireless clients
and provides a connection to a wired LAN.
AP Client
This mode provides the capability to connect with the other AP using
infrastructure/Ad-hoc networking types. With bridge operation mode, you can
directly connect the wired Ethernet port to your PC and the device becomes a
wireless adapter. And with WISP operation mode, you can connect the wired
Ethernet port to a hub/switch and all the PCs connecting with hub/switch can share
the same public IP address from your ISP.
WDS (Wireless Distribution System)
This mode serves as a wireless repeater; the device forwards the packets to another
AP with WDS function. When this mode is selected, all the wireless clients can’t
survey and connect to the device. The device only allows the WDS connection.
WDS+AP
This mode combines WDS plusAP modes, it not only allows WDS connections but

5
also the wireless clients can survey and connect to the device.
The following table shows the supporting combination of operation and wireless
radio modes.

Examples of Configuration
This example demonstrates how to set up a network with different device
configurations. There are 2 DHCP servers (DEV1/DEV4) in the network to control
the IP configuration of 2 domains (192.168.2.x/192.168.3.x). Once the setting is
done, all the PCs can visit Internet through DEV1.
We assume all the devices keep the factory default setting. To make sure that user
can continuing press the rest button for more than 5 seconds to restore the factory
default setting.
The following descriptions show the steps to configure DEV1 to DEV5.

7
Configure DEV1:
1. Connect the ADSL modem to Ethernet port of device using Ethernet cable.
2. Access the web server (http://192.168.2.254) of device from the wireless
station.
3. Use Wizard page to setup device.
4. Press “Next>>” button then set the “Operation Mode” to “Router” mode.
5. Press “Next>>” button then disable “Time Zone” function.

8
6. Press “Next>>” button then set the IP address of LAN interface.
7. Press “Next>>” button then select the “PPPoE” for “WAN Access Type” and
fill in the “User Name” and “Password” fields.
8. Press “Next>>” button then select the “AP+WDS” for “mode” and change the
SSID to “ZPlus-G120-DEV1”.
