Protected Setup) compliant. WPS allows you to easily connect to another WPS- enabled device. The NWD2205 is a USB adapter which connects to an empty USB port on your computer. See your NWD2205’s Quick Start Guide for installation instructions, and see the section on product specifications in this User’s Guide for detailed information.
Page 19: Application Overview
Infrastructure and connect to an AP or use Ad-Hoc mode and connect to a peer computer (another wireless device in Ad-Hoc mode). 1.3.1 Infrastructure To connect to a network via an access point (AP), set the NWD2205 network type to Infrastructure (see Chapter 4 on page 62).
Page 20: Ad-Hoc
After you install and start the ZyXEL utility, an icon for the ZyXEL utility appears in the system tray. Note: The ZyXEL utility system tray icon displays only when the NWD2205 is installed properly. Note: When you use the ZyXEL utility, it automatically disables Wireless Zero Configuration (WZC) in Windows XP.
Page 21: Configuration Methods
If you want to use the Windows XP wireless configuration tool to configure the NWD2205, you need to disable the ZyXEL utility. Right-click the utility icon ( in the system tray and select Exit. Figure 5 Enable WZC Refer to the appendices for information on how to use the Windows wireless configuration tool to manage the NWD2205.

Page 24: Before You Begin
Make sure that your access point is turned on and that it is within range of the computer with the NWD2205 installed. Make sure that you have installed the NWD2205’s driver and utility on your computer. In the NWD2205’s utility, click the Adapter tab, enable WPS and select PBC (Push Button Configuration).
Page 25: Pin Configuration
Chapter 2 Tutorial The AP sends the proper configuration settings to the NWD2205. This may take up to two minutes. Then the NWD2205 is able to communicate with the AP securely. The following figure shows you an example to set up wireless network and security by pressing a button on both the AP (the NBG334W in this example) and the NWD2205.
Page 26 Then the wireless client is able to communicate with the NBG334W securely. The following figure shows you the example of configuring the wireless network and security on the NWD2205 and the AP (ZyXEL’s NBG334W in this example) by using the PIN method.

(AP). Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is enabled, wireless client A and B can access the wired network and communicate NWD2205 User’s Guide...
Page 132 This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN. The Access Points not only provide communication with the wired network but also mediate wireless network traffic in the immediate neighborhood. NWD2205 User’s Guide...
Page 133 AP is using channel 1, then you need to select a channel between 6 or 11. RTS/CTS A hidden node occurs when two stations are within range of the same access point, but are not within range of each other. The following figure illustrates a NWD2205 User’s Guide...
Page 134 RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Note: Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy. NWD2205 User’s Guide...
Page 135: Fragmentation Threshold
Use the dynamic setting to automatically use short preamble when all wireless devices on the network support it, otherwise the NWD2205 uses long preamble. Note: The wireless devices MUST use the same preamble mode in order to communicate.

IEEE802.1x EAP with RADIUS Server Authentication Wi-Fi Protected Access (WPA) WPA2 Most Secure Note: You must enable the same wireless security settings on the NWD2205 and on all wireless clients that you want to associate with it. NWD2205 User’s Guide...
Page 137 The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication: • Access-Request Sent by an access point requesting authentication. • Access-Reject Sent by a RADIUS server rejecting access. • Access-Accept Sent by a RADIUS server allowing access. NWD2205 User’s Guide...
Page 138 The wireless client ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text. NWD2205 User’s Guide...
Page 139 However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco. LEAP LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x. NWD2205 User’s Guide...

RADIUS server, you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN. NWD2205 User’s Guide...
Page 141 The common-password approach makes WPA(2)-PSK susceptible to brute-force password-guessing attacks but it’s still an improvement over WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption NWD2205 User’s Guide...
Page 142 The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly. A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by the RADIUS server and the client. NWD2205 User’s Guide...
Page 143 The AP checks each wireless client's password and allows it to join the network only if the password matches. The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID. NWD2205 User’s Guide...
