CHAPTER 1
Introducing the ZyXEL Device
This chapter introduces the main applications and features of the ZyXEL Device. It also
introduces the ways you can manage the ZyXEL Device.
1.1 Overview
The ZyXEL Device is a 4-in-1 Access Point with Super G and Turbo G wireless technology.
Access Point (AP), repeater, bridge and wireless client functions allow you to use the ZyXEL
Device in various network deployments. Super G and Turbo G technology boost the wireless
data throughput.
The ZyXEL Device Access Point (AP) allows wireless stations to communicate and/or access
a wired network. It can work as a bridge and repeater to extend your wireless network. You
can also use it as a wireless client to access a wired network through another AP. The ZyXEL
Device uses IEEE 802.1x, WEP data encryption, WPA (Wi-Fi Protected Access), WPA2 and
MAC address filtering to give mobile users highly secured wireless connectivity. Both IEEE
802.11b and IEEE 802.11g compliant wireless devices can associate with the ZyXEL Device.
In addition to being highly flexible, the ZyXEL Device is easy to install and configure.
1.2 Applications for the ZyXEL Device
Here are some application examples of how you can use your ZyXEL Device.
1.2.1 Access Point for Internet Access
The ZyXEL Device is an ideal access solution for wireless Internet connection. A typical
Internet access application for your ZyXEL Device is shown as follows.

Chapter 1 Introducing the ZyXEL Device
Figure 1 Internet Access Application
1.2.2 Corporate Network Access Application
In situations where users need to access corporate network resources and the Internet, the
ZyXEL Device is an ideal solution for wireless stations to connect to the corporate network
without expensive network cabling. Stations A, B and C can access the wired network through
the ZyXEL Devices.
The following figure depicts a typical application of the ZyXEL Device in an enterprise
environment. The three computers with wireless adapters are allowed to access the network
resource through the ZyXEL Device after account validation by the network authentication
server.

The ZyXEL Device can function as a wireless client to connect to a network via an Access
Point (AP). The AP provides access to the wired network and the Internet.

1.2.4 Bridge / Repeater
The ZyXEL Device can act as a wireless network bridge and establish wireless links with
other APs. The ZyXEL Devices in the following example are using bridge mode with a star
configuration. A, B, C and D are connected to independent wired networks and have bridge
connections at the same time (B, C and D can communicate with A).
Chapter 1 Introducing the ZyXEL Device
Figure 4 Bridge Application
A ZyXEL Device in bridge mode without an Ethernet connection can function as a repeater. It
transmits traffic from one AP to another AP without using a wired connection. C in the
following graphic repeats wireless traffic between A and B.

1.2.5 Access Point and Repeater
Set the ZyXEL Device to AP+Repeater mode to have it simultaneously provide access for
wireless clients and use the repeater function. This allows you to extend the coverage of your
wireless network without installing Ethernet cable to connect the ZyXEL Device. In the
following figure, B is in AP+Repeater mode. B functions as an AP for wireless clients C and
D. B also repeats traffic between the wireless clients and AP A which is connected to the wired
network. You could also set AP A to AP+Repeater mode so that wireless clients could
connect to A as well.

1.3 Ways to Manage the ZyXEL Device
Use any of the following methods to manage the ZyXEL Device.
• Web Configurator. This is recommended for everyday management of the ZyXEL Device
using a (supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.

1.4 Good Habits for Managing the ZyXEL Device
Do the following things regularly to make the ZyXEL Device more secure and to manage the
ZyXEL Device more effectively.
• Change the password. Use a password that’s not easy to guess and that consists of
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the ZyXEL Device to its
factory default settings. If you backed up an earlier configuration file, you would not have
to totally re-configure the ZyXEL Device. You could simply restore your last
configuration.

1.6 Management Computer Setup
You can connect a computer to the ZyXEL Device for management purposes either using an
Ethernet connection (recommended for a first time management session) or wirelessly.
1.6.1 Wired Connection
You must prepare your computer/computer network to connect to the ZyXEL Device if you
are using a wired connection. Your computer's IP address and subnet mask must be on the
same subnet as the ZyXEL Device. This can be done by setting up your computer's IP address.
See the appendix for details on how to set up your IP address.
The following figure shows an example of accessing your ZyXEL Device via a wired
connection with an Ethernet cable.
Figure 8 Wired Connection
192.168.1.3
1.6.2 Wireless Connection
Ensure that the wireless stations have a compatible wireless card/adapter with the same
wireless settings as the ZyXEL Device. The following figure shows how you can access your
ZyXEL Device wirelessly.

ZyXEL G-570S v2 User’s Guide
Chapter 1 Introducing the ZyXEL Device
" The wireless stations and the ZyXEL Device must use the same SSID, channel
and wireless security settings for wireless communication.
" If you do not enable any wireless security on your ZyXEL Device, your network
traffic is visible to any wireless networking device that is within range.
1.7 Restarting the ZyXEL Device
Press and immediately release the RESET button to restart the ZyXEL Device.
" Holding the RESET button in for five seconds or longer resets the device to the
factory-default settings.
1.8 Resetting the ZyXEL Device
If you forget the ZyXEL Device's IP address or your password, to access the ZyXEL Device,
you will need to reload the factory-default using the RESET button. Resetting the ZyXEL
Device replaces the current configuration file with the factory-default configuration file. This
means that you will lose all configurations that you had previously. The following parameters
will be reset to the default values.

1.8.1 Methods of Restoring Factory-Defaults
You can erase the current configuration and restore factory defaults in two ways:
1 Use the RESET button on the ZyXEL Device to upload the default configuration file
(hold this button in for at least five seconds).
2 Use the web configurator. Click System > Management > Configuration File. From
here you can restore the ZyXEL Device to its factory default settings.
