CHAPTER 1
Introducing the ZyXEL Device
This chapter introduces the main applications and features of the ZyXEL Device. It also
discusses the ways you can manage your ZyXEL Device.
1.1 Introducing the ZyXEL Device
Your ZyXEL Device extends the range of your existing wired network without additional
wiring, providing easy network access to mobile users.
It controls network access with MAC address filtering and RADIUS server authentication.It
also provides a high level of network traffic security, supporting IEEE 802.1x, Wi-Fi
Protected Access (WPA), WPA2 and WEP data encryption. Its Quality of Service (QoS)
features allow you to prioritize time-sensitive or highly important applications such as VoIP.
Your ZyXEL Device is easy to install, configure and use. The embedded Web-based
configurator enables simple, straightforward management and maintenance.
See the Quick Start Guide for instructions on how to make hardware connections.
1.2 Applications for the ZyXEL Device
The ZyXEL Device can be configured to use the following WLAN operating modes
1 AP (Access Point)
2 Wireless Client
3 Bridge
4 AP + Bridge
Applications for each operating mode are shown below.
1.2.1 Access Point
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. Stations A, B and C
can access the wired network through the ZyXEL Devices.

1.2.2 Wireless Client
The ZyXEL Device can be used as a wireless client to communicate with an existing network.
In the figure below, the printer can receive requests from the wired computer clients A and B
via the ZyXEL Device in Wireless Client mode.

1.2.3 Bridge
The ZyXEL Device can act as a wireless network bridge and establish wireless links with
other APs. In the figure below, the ZyXEL Devices (A, B and Z) are connected to independent
wired networks and have a bridge connection (A can communicate with B and Z) at the same
time. Security between bridged APs (the Wireless Distribution System or WDS) is
independent of the security between the wired networks and their respective APs. If you do not
enable WDS security, traffic between APs is not encrypted. When WDS security is enabled,
both APs must use the same pre-shared key. See Section 6.4.3 on page 68 for more details.
Once the security settings of peer sides match one another, the connection between devices is
made.
At the time of writing, WDS security is compatible with other ZyXEL NWA-series access
points only. Refer to your other access point’s documentation for details.
Figure 3 Bridge Application
Chapter 1 Introducing the ZyXEL Device
In the example below, when both ZyXEL Devices are in Bridge mode, they form a WDS
(Wireless Distribution System) allowing the computers in LAN 1 to connect to the computers
in LAN 2.
ZyXEL NWA-1100 User’s Guide

Chapter 1 Introducing the ZyXEL Device
Figure 4 Bridging Example
Be careful to avoid bridge loops when you enable bridging in the ZyXEL Device. Bridge loops
cause broadcast traffic to circle the network endlessly, resulting in possible throughput
degradation and disruption of communications. The following examples show two network
topologies that can lead to this problem:
• If two or more ZyXEL Devices (in bridge mode) are connected to the same hub.
Figure 5 Bridge Loop: Two Bridges Connected to Hub
• If your ZyXEL Device (in bridge mode) is connected to a wired LAN while
communicating with another wireless bridge that is also connected to the same wired
LAN.

Chapter 1 Introducing the ZyXEL Device
Figure 6 Bridge Loop: Bridge Connected to Wired LAN
To prevent bridge loops, ensure that you enable STP in the Wireless screen or your ZyXEL
Device is not set to bridge mode while connected to both wired and wireless segments of the
same LAN.
1.2.4 AP + Bridge
In AP+Bridge mode, the ZyXEL Device supports both AP and bridge connection at the same
time.
Using AP + Bridge mode, your ZyXEL Device can extend the range of the WLAN. In the
figure below, A and B act as AP + Bridge devices that forward traffic between associated
wireless workstations and the wired LAN.
When the ZyXEL Device is in AP+Bridge mode, security between APs (the Wireless
Distribution System or WDS) is independent of the security between the wireless stations and
the AP. If you do not enable WDS security, traffic between APs is not encrypted. When WDS
security is enabled, both APs must use the same pre-shared key. See Section 6.4.4 on page 70
for more details.
Unless specified, the term “security settings” refers to the traffic between the wireless stations
and the ZyXEL Device.

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.
• CLI (Command Line Interface). Line commands are mostly used for troubleshooting by
service engineers.
• FTP (File Transfer Protocol) for firmware upgrades.
• SNMP (Simple Network Management Protocol). The device can be monitored by an
SNMP manager. See the SNMP chapter in this User’s Guide.
1.4 Configuring Your ZyXEL Device’s Security Features
Your ZyXEL Device comes with a variety of security features. This section summarizes these
features and provides links to sections in the User’s Guide to configure security settings on
your ZyXEL Device. Follow the suggestions below to improve security on your ZyXEL
Device and network.
1.4.1 Control Access to Your Device
Ensure only people with permission can access your ZyXEL Device.
30
• Control physical access by locating devices in secure areas, such as locked rooms. Most
ZyXEL Devices have a reset button. If an unauthorized person has access to the reset
button, they can then reset the device’s password to its default password, log in and
reconfigure its settings.
