Chapter 1- Wireless LAN Networking This section provides background information on wireless LAN networking technology. THE INFORMATION IN THIS SECTION IS FOR YOUR REFERENCE. CHANGING NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD ONLY BE DONE BY AN AUTHORIZED ADMINISTRATOR. Transmission Rate (Transfer Rate) The adapter provides various transmission (data) rate options for you to select. Options include Fully Auto, 1 Mbps, 2 Mbps, 5.
When a number of wireless stations are connected using a single access point, you have a Basic Service Set (BSS).
In the ESS diagram below, communication is done through the access points, which relay data packets to other wireless stations or devices connected to the wired network. Wireless stations can then access resources, such as a printer, on the wired network.
In an ESS environment, users are able to move from one access point to another without losing the connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the adapter automatically switches to the channel used in BSS (2).
W IRELESS L AN S ECURITY Because wireless networks are not as secure as wired networks, its vital that security settings are clearly understood and applied. The list below shows the possible wireless security levels on your adapter starting with the most secure. EAP (Extensible Authentication Protocol) is used for authentication and utilizes dynamic WEP key exchange.
D ATA E NCRYPTION WITH W E P The WEP (Wired Equivalent Privacy) security protocol is an encryption method designed to try to make wireless networks as secure as wired networks. WEP encryption scrambles all data packets transmitted between the adapter and the access point or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption.

2.6 Using the Utility to Configure Your Network The following are explanations on how to configure and use the Utility program. After completing the installation procedure, a new icon as shown below will automatically appear in the lower right tray bar. Hold your mouse pointer over the icon, and press the right mouse button to open the Wireless Client Utility. The Wireless Client Utility window as shown below will appear. The user can now use any of the management functions available in the IEEE 802.
Wireless Network Status Profile Name The name of the current selected configuration profile. Set up the configuration name on the Profile tab. SSID Displays the wireless network name. Link Status Shows whether the station is associated to the wireless network. Network Type The type of network the station is connected to. The options include: Infrastructure (access point) Ad Hoc Wireless Mode Displays the wireless mode. 802.11g or 11b Channel Shows the currently connected channel.
Connecting to a different network Hold your mouse pointer over the network icon, and click the right mouse button to select the network. Click the Connect button to connect the available network. If no configuration profile exists for that network, the Profile Settings window opens to ask to create a profile for the network. Follow the procedures to create profile for that network. 2.6.3 Profile To add a new configuration profile, click Add on the Profile tab.
Scan Available Networks Click the Browse button on the Profile Settings screen to scan for available infrastructure and ad hoc networks. On this list, click Refresh to refresh the list at any time. To configure a profile for Ad-Hoc or Infrastructure mode, select the Network Type field on the Profile Settings. Click Next to continue the profile setting.
To define the security mode, select the security button of the desired security mode. And then click Next to continue. Please see following table for details of security modes. WPA/WPA2 Enables the use of Wi-Fi Protected Access (WPA). Choosing WPA/WPA2 opens the WPA/WPA2 Security Settings screen. The options include: TLS (Transport Layer Security) is a Point-to-Point Protocol (PPP) extension supporting additional authentication methods within PPP.
TLS PEAP TTLS LEAP Advanced Settings After Security Settings finished, the Advanced Settings screen will be shown as following. The following table describes the items found on the Advanced Settings screen. Power Save Mode Shows the power save mode. Power management is disabled in ad hoc mode. The options include: Continuous Access Mode Maximum Power Saving Fast Power Saving 802.11b Preamble Displays the 802.11b preamble format.
After advance settings are finished, the following screen showed as below. You can activate the profile now or later. WPS Setting 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 detail indicates as follows.
1. Go to the box of Config Mode and select Enrollee. 2. Click "Rescan" button to update available WPS APs.
3. Select an AP (SSID/BSSID) that STA will join to. 4. Click "PIN" button to start PIN connection. 5. Enter PIN Code of STA into the Registrar when prompted by the Registrar. *Allow of an exchange between Step 4 and Step 5. *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.
6. The result will look like the below figure. 7. Configured and got one or multiple credential(s). 8. Then connect successfully. The result will look like the below figure.
9. Click "Detail" button. 10. You will look like the below figure. *If Credential#1 is reliable and present, system will connect with Credential#1. On the contrary, system will auto rotate to the next existed credential. *Also you can click "Rotate" button. Command to rotate to the next credential you want to use. Describe "WPS Status Bar" - "PIN - xxx" as follow : 1.
EAP-Rsp(Done) ~> Configured ~> WPS status is disconnected ~> WPS status is connected successfully-SSID 2. WPS configuration doesn't complete after two-minute connection : WPS Eap process failed. 3. When Errors occur within two-minute connection, the WPS status bar might report on "WPS Eap process failed". Error messages might be : 1. Receive EAP with wrong NONCE. 2. Receive EAP without integrity. 3. Error PIN Code. 4. An inappropriate EAP-FAIL received.

Glossary For unfamiliar terms used below, look for entries elsewhere in the glossary. AD-HOC (IBSS) Ad-hoc mode does not require an AP or a wired network. A network that transmits wireless from computer to computer without the use of a base station (access point). Two or more wireless stations communicate directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service Set (IBSS). CHANNEL A radio frequency used by a wireless device is called a channel.
ROAMING In an infrastructure network, wireless stations are able to switch from one BSS to another as they move between the coverage areas. During this period, the wireless stations maintain uninterrupted connection to the network. This is roaming. As the wireless station moves from place to place, it is responsible for choosing the most appropriate AP depending on the signal strength, network utilization among other factors.
