FCC Statement
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of
the following measures：
zReorient or relocate the receiving antenna.
zIncrease the separation between the equipment and receiver.
zConnect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
zConsult the dealer or an experienced radio/TV technician for help.
FCC RF Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated
with minimum distance 20cm between the radiator & your body. For product
available in the USA/Canada market, only channel 1~11 can be operated.
Selection of other channels is not possible. The antenna(s) used for this
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter. Shielded interface cables must be used in order to
comply with emission limits.

Ch 1. ZWA-G220 Installation
Packing List
Before you start to install the device, make sure the package contains the
following items：
●ZWA-G220 Multi-Mode AP unit * 1
●Power Adapter * 1
●RJ-45 Cable * 1
Multi-Mode AP Power Adapter
RJ-45 Cable
Back panel connections
From Left to Right:
DC jack: ZW-220 can use power source in DC jack. Please supply the power in

7
5V and 2A
WAN/LAN: This port could be WAN or LAN port depending on the
configuration. It will be WAN port in router mode and LAN port in
bridge mode.
LAN: This port is always LAN in ZW-220. In Bridge mode, it bridges to WLAN
and “WAN/LAN” port. In Router mode, it bridges to WLAN only, In WISP
mode, it bridges to “WAN/LAN” port only.
Reset: Press Reset button to revert it to factory default.
Antenna: This SMA Reverse allows the user to connect antenna or RF cable.
At least connect an antenna to help ZW-220 to send and receive RF
signal.
ZW-220 integrates LNA/PA (Low Noise Amplifier) module and has at
lease 3dB RF sensitivity better than the regular WLAN products.
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 WLAN
(Wireless Local Area Network) and both wired LAN ports. And in
router/WISP modes, the device can be accessed by WLAN, LAN 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
The device can act as the following roles, and it supports WDS (Wireless
Distribution System) function.
zAccess Point
zWDS mode
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 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 other wired
Ethernet (LAN) port bridges to the private WLAN. The NAT is existed
between WAN and WLAN/LAN and all the wireless and wired 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 two wired Ethernet ports 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 from your ISP to the PCs connecting with both the
wired Ethernet ports of the device. To use this mode, first you must set the
wireless radio to be client mode connecting to the AP of your ISP as the
WAN connection and 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 one of the wired Ethernet port to your PC and the
device becomes a wireless adapter. And with WISP operation mode, you
can connect one of 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.
