CHAPTER 1
Getting to Know Your ZyXEL
Device
This chapter introduces the main features and applications of the ZyXEL Device.
1.1 ZyXEL Device Overview
The ZyXEL Device is the ideal secure wireless firewall router for all data passing between the
Internet and your Local Area Network.
You can configure firewall and/or content filtering for secure Internet access. You can also use
media bandwidth management to efficiently manage traffic on your network. The Quality of
Service (QoS) features allow you to prioritize time-sensitive or highly important applications
such as VoIP.
The ZyXEL Device has an embedded mini-PCI module for 802.11g Wireless LAN
connectivity. The ZyXEL Device supports the IEEE 802.11b and g standards, so that either
IEEE 802.11b or IEEE 802.11g compatible clients can wirelessly access the ZyXEL Device or
the wired network behind it. the ZyXEL Device allows you to access wireless networks at
speeds of up to 108Mbps (with the Super G function enabled)
" Only use firmware for your ZyXEL Device’s specific model.
1.2 Applications for the ZyXEL Device
Here are some examples of what you can do with your ZyXEL Device.
1.2.1 Secure Broadband Internet Access
You can connect a cable modem, DSL or wireless modem to the ZyXEL Device for broadband
Internet access via an Ethernet or a wireless port on the modem. The ZyXEL Device
guarantees not only high speed Internet access, but secure internal network protection and
traffic management as well.

1.2.1.1 Wireless LAN Application
Add a wireless LAN to your existing network without expensive network cables. Wireless
stations can move freely anywhere in the coverage area and use resources on the wired
network.
Figure 2 WLAN Application Example
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.
