Quick Start 2.1 Installation and Device Connection Install the CD-ROM software driver before you plug in the USB adapter to you PC or laptop computer. This avoids the USB adapter being recognized by another existing WiFi software driver which might not be fully compatible with the original software driver. Before making any device and cable connection to the computer, you have to install the CD software driver and utility from fresh. Insert the CD-ROM into the CD/DVD drive of your computer. As soon as the AutoPlay window appears, double click SETUP.EXE to install the software driver. If the AutoPlay window does not pop up, you could also go to the CD/DVD drive under My Computer and double click the SETUP icon. Reboot your computer. Once completed, you could plug in the USB adapter to any spare USB port of your computer using the USB2.0 cable supplied in the kit. DN-WLAN-028 Page 4 Instruction Manual 1. Scanning the WiFi Signal A Quick Guide 1.1 RALINK WIRELESS UTILITY (RaUI) OR WINDOWS ZERO CONFIGURATION (WZC) As the title suggests, two types of wireless utilities are possible. The Windows Zero Configuration provides the basic wireless networking configuration whose user interface is consistent across various Windows Operating Systems from XP, VISTA to Windows 7; and the more sophisticated RaLink Wireless Utility with the WPA supplicant functionality. As soon as Windows starts, you could find the RaUI icon at the lower right hand corner of the computer screen. Right-click RaUI allows you to toggle between RaUI and WZC. RaUI can work in parallel with WZC. When WZC is active, RaUI provides only the monitoring function, such as showing the link stats, network status, statistic counters, advance feature status, WMM status and WPS status. It wont interfere with WZCs configuration or profile functions. 1.2 Working with WZC Go to Section 1.3 if you want to use RaUI instead. When WZC is activated, the RaUI screen becomes:
(i) The Profile button turns grey. The profile function is removed since the NIC (i.e. Network Interface Card) is now being controlled by WZC.
(ii) The Connect and Add Profile functions turn grey. DN-WLAN-028 Page 5 Instruction Manual 1.2.1 Configuration of NIC by using WZC Before you connect to any wireless network, the status prompt pops up like this:
DN-WLAN-028 Page 6 Instruction Manual Right click the Network Connection icom in the task bar, and select View Available Wireless Networks:
A new window pops up showing the list of AP available for connection. You may either double click the AP or highlight it with the mouse pointer followed by clicking Connect Anyway. DN-WLAN-028 Page 7 Instruction Manual DN-WLAN-028 Page 8 Instruction Manual If you want to update the AP attributes, click Change Advanced Settings. Then choose the Wireless Networks. DN-WLAN-028 Page 9 Instruction Manual 1.3 Working with RaUI When RaUI is active, a small RaUI icon appears at the lower right hand corner of the screen. Click on it to bring up the RaUI main window and you may see a list of AP picked up by the antenna. Each row contains the SSID, network type, channel used, wireless mode, security status and signal strength. DN-WLAN-028 Page 10 Instruction Manual Simply highlight the AP and click Connect. If the AP is encrypted, you shall then be asked to enter the password for authentication. Once connected, a small blue arrow appears on the left of the AP. How does the RaUI icon represent the various network statuses? Here are the clues:
Connected and signal strength is Good. Connected and signal strength is Normal. Not Connected. Wireless NIC not detected. Connected but signal strength is Weak. DN-WLAN-028 Page 11 Instruction Manual 2. Advanced RaUI Features Consists of:
PROFILE NETWORK ADVANCED STATISTICS WMM WPS RADIO ON/OFF 2.1 PROFILE A place to save your favorite wireless networks for one-click connection. Profile Name: Default is PROF1 SSID: AP or Ad-Hoc name Network Type: Infrastructure or Ad-Hoc Authentication: Open, WPA/PSK, WPA2/PSK Encryption: None, WEP, AES, TKIP USB802.1x: NO or In use Tx Power: Auto or Adjustable %
Channel: Auto or Specific channel RTS Threshold: Data packet size which exceeds the Request To Send (RTS) Threshold will be sent out. Larger packet size favors data transmission whilst small pack size lowers the latency for real time traffic (voice and video). Fragment Threshold: Longer data fragment increases data throughput performance with good signal quality. The opposite is true to keep shorter data fragment in poor signal quality to maintain an optimal data throughput. DN-WLAN-028 Page 12 2.1.1 Example to Add a PROFILE Click Add under PROFILE Instruction Manual The Add Profile page will then pop up. DN-WLAN-028 Page 13 Instruction Manual The default Profile Name is PROF1 which you may change to a different name. Now move the mouse to the SSID pull down menu and select the AP from an active list. DN-WLAN-028 Page 14 Instruction Manual Suppose that you have chosen AP1 to save the profile, you could now highlight it and click Activate to connect. DN-WLAN-028 Page 15 Instruction Manual DN-WLAN-028 Page 16 2.2 Network A list of AP picked up by the antenna. Instruction Manual SSID: Name of Wireless Network Network Type: Infrastructure or Ad-Hoc Channel: Specific Channel in use Wireless Mode: 802.11b, 802.11g or 802.11n Security-Enable: The type of Encryption in use Signal: Strength in %. To connect to an AP, simply highlight it, followed by clicking the Connect button. If the intended network has encryption other than Not Use, the RaUL will bring up the security page which allows the user to enter the password to complete the connection. When you double click the AP, you can see the APs detailed information under the buttons of General, WPS, CCX and 802.11n. DN-WLAN-028 Page 17 Instruction Manual 2.2.1 Network General The General information contains APs SSID, MAC address, authentication type, encryption type, channel, network type, beacon interval, signal strength and supported rates (Mbps). The Beacon Interval specifies the duration between beacon packets. Access Points broadcast Beacons or Traffic Indication Messages (TIM) in order to synchronize wireless networks. The default setting of 100 should be ideal for most situations. In a "noisy" environment - one with much interference -
decreasing the Beacon Interval may improve network performance. In very remote locations (with few wireless nodes) this value may be increased. DN-WLAN-028 Page 18 Instruction Manual 2.2.2 Network WPS Wi-Fi Protected Setup (WPS) is a standard for easy and secure establishment of a wireless home network, created by the Wi-Fi Alliance and officially launched on January 8, 2007. The goal of the WPS protocol is to simplify the process of configuring security on wireless networks, and so it was first named 'Wi-Fi Simple Config'. The protocol is meant to allow home users who know little of wireless security and may be intimidated by the available security options to configure Wi-Fi Protected Access, which is supported by all Wi-Fi certified devices. The standard achieves its goal by putting much emphasis into usability and security, and the concept is implemented through four usage models that enable a user to establish a home network. So, to add a new device to the Network the user can have up to the following two choices:
PIN Method, in which a PIN (Personal Identification Number) has to be read from either a sticker on the new wireless client device (STA) or a display, if there is one, and entered at the "representant" of the Network, either the wireless access point (AP) or a Registrar of the Network, cf below the Protocol Architecture. This is the mandatory baseline model, every Wi-Fi Protected Setup certified product must support it. PBC Method, in which the user simply has to push a button, either an actual or virtual one, on both the AP (or a Registrar of the Network) and the new wireless client device (STA). Support of this model is mandatory for APs and optional for STAs. This page addresses the common scenario involving an Infrastructure Network. The support of ad hoc networks (IBSS) are not supported by WPS. The WPS information contains the authentication type, encryption type, config methods, device password ID, selected registrar, state, version, AP setup locked, UUID-E and RF bands. Authentication Type - There are three types of authentication modes supported by RaConfig: OPEN, SHARED, WPA-PSK and WPA system. Encryption Type For OPEN and SHARED authentication mode, the selection of encryption type are NONE, WEP. For WPA, WPA2, WPA-PSK and WPA2-PSK authentication mode, the encryption type supports both TKIP AND AES. Config Methods This corresponds to the methods the AP supports as an Enrollee for adding external Registrars. Value 0x0001 0x0002 0x0004 0x0008 0x0010 0x0020 0x0040 0x0080 0x0100 Hardware Interface USBA (Flash Drive) Ethernet Label Display External NFC Token Integrated NFC Token NFC Interface Push Button Keypad DN-WLAN-028 Page 19 Instruction Manual Device Password ID This indicates the method or indentifies password that the selected Registrar intends to use. AP in PBC mode must indicate 0x0004 within two minutes. Value 0x0000 0x0001 0x0002 0x0003 0x0004 0x0005 0x0006-0x000F Description Default (PIN) User-specified Rekey Display Push Button (PBC) Registrar-specified Reserved Selected Registrar This indicates if the user has recently activated a Registrar to add an Enrollee. The values are TRUE and FALSE. State The current configuration state on AP. The values are Un-configured and Configured. Version WPS specified version. AP Setup Locked This indicate if the AP has entered a setup locked state. UUID-E The universally unique identifier (UUID) element generated by the Enrollee, a 16 bytes value. RF Bands This indicates all RF bands available on the AP. A dual-band AP must provide it. The values are 2.4GHz and 5GHz. 2.2.3 Network CCX (Cisco Compatible Extensions) The Cisco Compatible Extensions program for Wi-Fi tags allows customers with a Cisco Unified Wireless Network and a Cisco Location solution to benefit from the latest innovation and technology advancements offered by Ciscos technology partners. This program offers improved consistency and interoperability among Ciscos Compatible Extensions technology partners. The CCX information contains CCKM, Cmic and Ckip. CCKM, CMIC and CKIP are Cisco proprietary protocols for Aironet 350. 2.2.4 Network 802.11n The 802.11n button appears only for AP supporting it. The box contains debugging information for internal RaLink engineer use.
