1. Windows Wireless Utility 1.1 Windows Zero Configuration for XP 1.1.1 Ralink Wireless Utility and Windows Zero Configuration Windows XP includes a wireless configuration utility named "Windows Zero configuration" (WZC) which provides basic configuration functions to the Ralink Wireless NIC. Ralink's utility (RaUI) additionally provides WPA functionality. To make it easier for the user to select the correct utility. RaUI will let users make a selection when it first runs after windows XP boots.
When activating WZC, there are several difference with the RaUI status, compared to the RaUI status without WZC running. z The profile button will be gray. Profile functionality is removed since the NIC is controlled by WZC. z The Connect and Add Profile function will be gray. Profile functionality is removed since the NIC is controlled by WZC. Please read through this document for full details on the other functions provided by RaUI. 1.1.

z z Figure 2-7-1-1 WPS Profile PIN Code: The user is required to enter an 8-digit PIN Code into Registrar. When an STA is the Enrollee, you can click "Renew" to re-generate a new PIN Code. Config Mode: The station serving as an Enrollee or an external Registrar. Figure 2-7-1-2 WPS PIN function After the user clicks PIN or PBC, please do not rescan within two-minutes of the connection. If you want to abort this setup within the interval, restart PIN/PBC or click "Disconnect" to stop WPS action.
2.7.2 Example to Add to Registrar Using PIN Method The user obtains a device password (PIN Code) from the STA and enters the password into the Registrar. Both the Enrollee and the Registrar use PIN Config method for the configuration setup. The following image outlines the process. z Select an AP (SSID/BSSID) that STA will join to and Select the “PIN/numeric code” method. z Select "Enrollee" from the Config Mode drop-down list.
If you use Microsoft Window Connection Now as an External Registrar, you must start PIN connection at STA first. After that, search out your WPS Device name and MAC address at Microsoft Registrar. Add a new device and enter PIN Code of STA at Microsoft Registrar when prompted. z Click “PIN” to enter the PIN z The result should appear as the image below.
z Then connect successfully. The result appears as the following image.

2.7.4 Example to Configure a Network/AP Using PIN or PBC Method Select an AP (SSID/BSSID) that STA will config and Select the “PIN/numeric code” method. z z Select “Registrar” from the Config Mode drop-down list. Enter the PIN Code of the STA into the Registrar when prompted by the Registrar.
z Enter the details of the credential and change configurations (SSID, Authentication, Encryption and Key) manually if needed. Start PIN or PBC. The following procedures are as similar as section 2-7-3 (PIN Enrollee Setup) or section 2-7-4(PBC Enrollee Setup), z If your AP Enrollee has been configured before the WPS process, the credential you set in advance will be updated to the AP itself.
3. Security 3.1 Auth.\ Encry. Setting – WEP/TKIP/AES z z z Figure 3-1 Auth.\Encry. Settings in the Profile Page Authentication Type: There are 7 authentication modes supported by RaUI. They are Open, Shared, WPA and WPA-PSK, WPA2 and WPA2-PSK, 802.1x, WAPI-PSK and WAPI-CA. Encryption Type: For open and shared authentication mode, the available encryption types are none and WEP. For Shared and 802.1x authentication mode, the selection of available encryption is WEP.
z z Figure 3-1-3 Pre-shared Key Configuration Pre-shared Key: This is the shared key between the AP and STA. If operating in WPA-PSK and WPA2-PSK authentication mode, this field must be filled with a key between 8 and 32 characters in length. Figure 3-1-4 WEP Key Configuration WEP Key: Only valid when using WEP encryption algorithm. The key must match the AP's key. There are several formats to enter the keys. 1. Hexadecimal - 40bits: 10 Hex characters. 2. Hexadecimal - 128bits: 32Hex characters. 3.
Authentication type: z PEAP: Protect Extensible Authentication Protocol. PEAP transport securely authenticates data by using tunneling between PEAP clients and an authentication server. PEAP can authenticate wireless LAN clients using only server-side certificates, thus simplifying the implementation and administration of a secure wireless LAN. z TLS/Smart Card: Transport Layer Security. Provides for certificate-based and mutual authentication of the client and the network.
Tunnel Password: Password for tunnel. ID \ PASSWORD z Authentication ID/Password: The identity, password and domain name for server. Only "EAP-FAST" and "LEAP" authentication can key in domain name. Domain names can be keyed in the blank space. z Tunnel ID/Password: Identity and Password for the server.. Client Certification z Use Client certificate: Client certificate for server authentication.
z z z Certificate issuer: Select the server that issues the certificate. Allow intermediate certificates: It must be in the server certificate chain between the server certificate and the server specified in the "certificate issuer must be" field. Server name: Enter an authentication sever root. 3.3 Example to Configure Connection with WEP on z Select an AP with WEP encryption and click "Connect". z The Auth.\Encry.
z Enter 1234567890 in the Key#1 Hexadecimal field. This value is same as our intended AP's setting. z Click "OK".
3.4 Example to Configure Connection with WPA-PSK z Select the AP with a WPA-PSK authentication mode and click "Connect". z Auth.\Encry. function appears. z Select WPA-PSK as the Authentication Type. Select TKIP or AES encryption. Enter the WPA Pre-Shared Key as "12345678".
z Click "OK". Be careful, if the WPA Pre-Shared Key entered is not correct, you won’t be able to exchange any data frames, even though the AP can be connected.
3.5 Example to Configure Connection with WPA z Select an AP with WPA authentication mode and click "Connect". z The Auth.\Encry. function pop up. (If AP setup security to Both (TKIP + AES), system defines is AES that security is severely.) z Click "8021X" and the setting page will appear.
