Figure 6 Infrastructure Network
2.1.1 What You Can Do in This Tutorial
• Connect securely either to an infrastructure AP using the WPS protocol. See
Section 2.2 on page 24 for details.
• Connect securely to an infrastructure AP using many of the strongest and most
common encryption protocols. See Section 2.3 on page 29 for details.
• Save a your settings so that you can later connect again to an infrastructure AP
with a single click. See Section 2.3.2 on page 31 for details.
• Configure your NWD2105 as an Access Point (AP), allowing other devices to
connect to it and share its network connections. See Section 2.4 on page 34 for
details.
2.1.2 What You Need to Know
The following term may help as you read through this section.
WPS
Wi-Fi Protected Setup (WPS) is a security protocol that lets two or more devices
connect securely to one another with a minimum amount of hassle on your part. It
most cases, establishing a secure connection with another WPS device is as easy
as pushing a button.
NWD2105 User’s Guide
23
Chapter 2Tutorial
2.1.3 Before You Begin
• Make sure that you have already familiarized yourself with the NWD2105’s
features and hardware, as described in Chapter 1 on page 17.
• You should have valid login information for an existing network Access Point,
otherwise you may not be able to make a network connection right away.
2.2 Connecting to an AP using Wi-Fi Protected
Setup (WPS)
This section gives you an example of how to set up your wireless network using
WPS. This example uses the NWD2105 as the wireless client, and ZyXEL’s
NBG334W as the Access Point (AP).
Note: The Access Point must be a WPS-aware device.
There are two WPS methods for creating a secure connection. This tutorial shows
you both.
• Push Button Configuration (PBC) - create a secure wireless network simply
by pressing a button. See Section 2.2.1 on page 24.This is the easier method.
• PIN Configuration - create a secure wireless network simply by entering a
wireless client's PIN (Personal Identification Number) in the NWD2105’s
interface. See Section 2.2.2 on page 25. This is the more secure method, since
one device can authenticate the other.
2.2.1 Push Button Configuration (PBC)
1 Make sure that your access point is turned on and that it is within range of the
computer with the NWD2105 installed.
2 Make sure that you have installed the NWD2105’s driver and utility on your
computer.
3 In the NWD2105’s utility, click the Adapter tab, enable WPS and select PBC
(Push Button Configuration). In the screen that appears, click Start.
4 Log into the AP’s web configurator and locate its WPS settings section. On the
NBG334W, press the Push Button button in the Network > Wireless Client >
WPS Station screen.

2.3 Connecting to an AP Without Using WPS
There are three ways to connect the wireless client (the NWD2105) to a network
without using WPS.
• Configure nothing and leave the wireless client to automatically scan for and
connect to any available network that has no wireless security configured.
• Manually connect to a network (see Section 2.3.1 on page 29).
• Configure a profile to have the wireless client automatically connect to a specific
network or peer computer (see Section 2.3.2 on page 31).
2.3.1 Manually Connecting to a Wireless LAN
This example illustrates how to manually connect your wireless client to an access
point (AP) configured for WPA-PSK security and connected to the Internet. Before
you connect to the access point, you must know its Service Set IDentity (SSID)
and WPA-PSK pre-shared key. In this example, the AP’s SSID is “SSID_Example3”
and its pre-shared key is “ThisismyWPA-PSKpre-sharedkey”.
After you install the ZyXEL utility and then insert the wireless client, follow the
steps below to connect to a network using the Site Survey screen.
1 Open the ZyXEL utility and click the Site Survey tab to open the screen shown
next.
Figure 9 ZyXEL Utility: Site Survey
2 The wireless client automatically searches for available wireless networks. Click
Scan if you want to search again. If no entry displays in the Available Network
List, that means there is no wireless network available within range. Make sure
the AP or peer computer is turned on, or move the wireless client closer to the AP
or peer computer. See Table 4.4 on page 54 for detailed field descriptions.
NWD2105 User’s Guide
29
Chapter 2Tutorial
3 To connect to an AP or peer computer, either click an entry in the list and then
click Connect or double-click an entry (SSID_Example3 in this example).
4 When you try to connect to an AP with security configured, a window will pop up
prompting you to specify the security settings. Enter the pre-shared key and leave
the encryption type at the default setting.
Use the Next button to move on to the next screen. You can use the Back button
at any time to return to the previous screen, or the Exit button to return to the
Site Survey screen.

6 The ZyXEL utility returns to the Link Info screen while it connects to the wireless
network using your settings. When the wireless link is established, the ZyXEL
utility icon in the system tray turns green and the Link Info screen displays
details of the active connection. Check the network information in the Link Info
screen to verify that you have successfully connected to the selected network. If
the wireless client is not connected to a network, the fields in this screen remain
blank. See Table 4.3 on page 51 for detailed field descriptions.
Figure 12 ZyXEL Utility: Link Info
7 Open your Internet browser and enter http://www.zyxel.com or the URL of any
other web site in the address bar. If you are able to access the web site, your
wireless connection is successfully configured. If you cannot access the web site,
check the Troubleshooting section of this User's Guide or contact your network
administrator if necessary.
2.3.2 Creating and Using a Profile
A profile lets you automatically connect to the same wireless network every time
you use the ZyXEL utility. You can also configure different profiles for different
networks, for example if you connect a notebook computer to wireless networks at
home and at work.
This example illustrates how to set up a profile and connect the wireless client to
an access point configured for WPA-PSK security. In this example, the AP’s SSID is
“SSID_Example3” and its pre-shared key is “ThisismyWPA-PSKpre-sharedkey”.
You have chosen the profile name “PN_Example3”.
