Step 1. Configuration utility will scan for available wireless access points automatically. Please select an access point to connect, and click . If the AP you wish to connect is not in the list, please press to renew the interface. Some function includes more information, and can not be fitted in setup area.
3.2.1 Scan for Other Wireless Devices There are two kinds of wireless connection mode: Infrastructure and Ad-Hoc. Infrastructure mode is used by wireless access points, which is able to establish wireless connection for you and other wireless/wired network clients.
y If the wireless device uses encryption, the user must know its encryption key in order to connect. Please launch utility and it will scan for wireless access points near by: Parameter SSID Description The SSID of the wireless access point or wireless device selected by user will be displayed here. When the SSID of access point or wireless device is not available, users have to input it here manually.
If users cannot see the access point, please click ‘Rescan’ button to scan for access point again, until the one preferred is displayed on the interface. Users may have to click ‘Rescan’ for more than two times before the access point wish to connect appears. If user still cannot see the access point after clicking ‘Rescan’ for more than five times, please move the computer closer to the wireless access point.
Step 1. Click the wireless access point or network device to connect, it will be highlighted, then click on ‘Connect’. If the access point selected does not use encryption, it will connect to this device within one minute. If the access point selected uses encryption, please proceed to step 3. Step 2. If the wireless access point does not have SSID, user will be prompted to input it in the field provided.
Step 4. Please ask the owner of the wireless access point for the security information, and input the correct key here and then click on ‘OK’. By checking ‘Show Password’ box, the encryption key inputted here will be displayed. Authentication type will be selected by the access point automatically, please do not change it. However, if the user connecting to an access point uses 802.1x authentication, they will be required to check ‘802.1x’ box and input related information. Step 5.
3.2.3 Add Access Point to Profile If users connect to some specific wireless access point frequently, they can add their information to the profile. Just like the telephone directory, the profile saves all information of access points, and user can recall them anytime. User can add an access point in the ‘Network’ tab to profile, or input all information of an access point manually.
Parameter Profile Name SSID Network Type Tx Power Preamble Channel Power Save Mode RTS Threshold Fragment Threshold Description User can give this profile a name. Every profile needs a unique name. Please input the SSID of this access point. If user selected an access point from the list, and SSID is not hidden, it will be filled automatically. However, user can modify the SSID if necessary. Please select the network type: Ad hoc or Infrastructure.
Parameter Authentication Encryption WPA Preshared Key Show Password Use 802.1x Description Select the authentication type of the wireless access point or wireless device in this field. When users are adding a profile from an existing access point or wireless device, authentication type will be selected automatically.

3.2.4 Using Windows Zero Configuration Windows XP and Vista has a built-in wireless network configuration utility, called ‘Windows Zero Configuration’ (WZC). Users can also use WZC to configure the wireless network parameter. Step 1. Right-click on configuration utility icon and select
Step 3. Click . Step 4. Right-click ‘Wireless Network Connection’ (it may have a number as suffix if you have more than one wireless network card, please make sure you right-click the ‘802.11n Wireless LAN Card), then select ‘View Available Wireless Networks’. Step 5. All wireless access points within proximity will be displayed here.
to the access point. Otherwise, users can press refresh button to rescan access points. Select the access point if it’s shown, then click . Step 6. If the wireless access point uses encryption, users will have to input the correct WEP passphrase or WPA pre-shared key. Ensure both the AP and PC is set with the same WEP passphrase/WPA pre-shared key. Otherwise the wireless connection will fail to establish.
3.2.5 Profile Management If users need to connect to different wireless access points at different time, they can store the connection parameters (encryption, passphrase, security etc, etc.) as a profile for every access point. Click the ‘Profile’ menu and all profiles will be listed in ‘Profile List’. Users can select a profile from the list and all information about selected profile will be listed.
Add a Profile If users want to create new profile, click ‘Profile’ menu, then press ‘Add’ button. The interface will prompt the user to input detailed information of access point.
If users have added a profile before, and they wish to change the content of the profile, they can use this function. Please select a profile from the list, and then click on ‘Edit’ button. The interface will provide contents of selected profile for editing. Click on ‘OK’ to save changes, or click ‘Cancel’ to discard changes. Delete an Existing Profile If users no longer need a profile, they can delete it via this function.
Activate a Profile When users want to connect to a specific wireless device in the profile list, they can select it and click ‘Activate’ button to establish connection.
When a profile is selected and click on ‘Activate’ button, an icon will be displayed in front of the profile to show that the connection has failed. When the connection is successfully established, an icon will be displayed. 3.2.6 Advanced Settings This wireless network card provides several advanced settings for experienced wireless users.

Chapter 6 Glossary 1. What is the IEEE 802.11g standard? 802.11g is the new IEEE standard for high-speed wireless LAN communications that provides up to 54 Mbps data rate in the 2.4 GHz band. 802.11g is quickly becoming the next mainstream wireless LAN technology for the home, office and public networks. 802.11g defines the use of the same OFDM modulation technique specified in IEEE 802.11a for the 5 GHz frequency band and applies it in the same 2.4 GHz frequency band as IEEE 802.11b. The 802.
z RTS/CTS Feature z Fragmentation z Power Management 4. What is Ad-hoc? An Ad-hoc integrated wireless LAN is a group of computers with their own Wireless LAN Card connecting as an independent wireless LAN. Ad hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation. 5. What is Infrastructure? An integrated wireless and wired LAN is called an Infrastructure configuration.
9. What is AES? AES (Advanced Encryption Standard), a chip-based security, has been developed to ensure the highest degree of security and authenticity for digital information, while making more efficient use of hardware and/or software than previous encryption standards. It is also included in IEEE 802.11i standard. Compare with AES, TKIP is a temporary protocol for replacing WEP security until manufacturers implement AES at the hardware level. 10.
13. What is Spread Spectrum? Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communication systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security.
16. What is GI? GI stands for Guard Interval. It’s a measure to protect wireless devices from crossinterference. If there are two wireless devices using the same or near channel, and they are close enough, radio interference will occur and reduce the radio resource usability. 17. What is STBC? STBC stands for Space-Time Block Coding, which is a technique used to transfer multiple copies of data by multiple antenna, to improve data transfer performance.
