Getting Started 1.1 Overview The ZyXEL NWD2205 wireless N USB adapter brings you a better Internet experience over existing IEEE 802.11 b/g/n networks. With data rates of up to 300 Mbps, you can enjoy a high-speed connection at home or in the office. It is an excellent solution for daily activities such as file transfers, music downloading, video streaming and online gaming.
IEEE 802.11b/g wireless networks. The NWD2205 is WPS (Wi-Fi Protected Setup) compliant. WPS allows you to easily set up a secure connection with another WPS-enabled device. The NWD2205 is a USB adapter which connects to an empty USB port on your computer. Figure 1 The NWD2205 The following table describes the NWD2205.

You then see a screen telling you that you must restart the computer after the installation completes. Click Continue Installation. The driver will automatically install. After installing the ZyXEL utility and device driver, you must restart your computer. Click Restart to reboot your computer and complete the driver installation.
1.3.3 Uninstalling the ZyXEL Utility You need to remove the ZyXEL utility from your computer only when you want to upgrade the ZyXEL utility or the ZyXEL utility cannot work properly. Note: Disconnect the NWD2205 if you are going to uninstall or upgrade the ZyXEL utility.
Page 20
Chapter 1 Getting Started Double-click your Macintosh OS’s driver folder on the included disc. Double-click the file Uninstall.command. The command screen displays. Enter the administrative password you use to log in to the Mac computer and press [ENTER]. NWD2205 User’s Guide...
Insert the NWD2205 into an available USB port on the computer. The NWD2205’s LED (light) turns on if it is properly inserted. Note: Never bend, twist or force the NWD2205 into the port. If there is not enough space to attach the NWD2205, use the included USB cable.
(another wireless device in Ad-Hoc mode). Infrastructure To connect to a network via an access point (AP), set the NWD2205 network type to Infrastructure. Through the AP, you can access the Internet or the wired network behind it.
Page 23
To set up a small independent wireless workgroup without an AP, use Ad-Hoc. Ad-Hoc does not require an AP or a wired network. Two or more wireless clients communicate directly with each other. Note: Wi-Fi Protected Setup (WPS) is not available in ad-hoc mode. Figure 3 Application: Ad-Hoc NWD2205 User’s Guide...

In this case, AP1 must be the registrar, since it is configured (it already has security information for the network). AP1 supplies the existing security information to Client 2. Figure 8 WPS: Example Network Step 2 REGISTRAR EXISTING CONNECTION CLIENT 1 ENROLLEE CLIENT 2 NWD2205 User’s Guide...
For instance, if you have two enrollees and one registrar you must set up the first enrollee (by pressing the WPS button on the registrar and the first enrollee, for example), then check that it successfully enrolled, then set up the second device in the same way. NWD2205 User’s Guide...

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.
Wireless security is vital to your network to protect wireless communication between wireless clients, access points and the wired network. Wireless security methods available on the NWD2205 are data encryption, wireless client authentication, restricting access by device MAC address and hiding the NWD2205 identity.

For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner. NWD2205 User’s Guide...

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. NWD2205 User’s Guide...
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA or WPA2 and WEP are improved data encryption and user authentication. NWD2205 User’s Guide...

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...
