Chapter 3 Wireless LAN Network This chapter provides background information on wireless LAN network. 3.1 Wireless LAN Overview This section describes applications of IEEE 802.11n Wireless LAN USB Adapter. 3.1.1 SSID The SSID is the unique ID used by Access Points and stations to identify a wireless Network. Wireless clients associating to any Access Point must have the same SSID. The default setting is ANY, which allows your IEEE 802.
3.2 Wireless LAN Security Overview Wireless LAN security is vital to your network to protect wireless communications against hacker entering your system and prevent unauthorized wireless station from accessing data transmitted over the network; the WLAN Utility offers a sophisticated security algorithm. Configure the wireless LAN security by clicking the check box next to Security Enable. A privacy Configuration window will appear. If you do not enable any wireless security on your IEEE 802.
3.2.1 Data Encryption with WEP WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the wireless LAN adapter and the AP or other wireless station to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption. The IEEE 802.11n Wireless LAN USB Adapter allows you to configure up to four 64-bit, or 128-bit WEP keys and only one key is used as the default key at any one time.
wireless stations and encryption key management. Authentication can be done using an external RADIUS server. 3.2.2.1 EAP Authentication EAP (Extensible Authentication Protocol) is an authentication protocol which runs on the top of IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication.
WPA-PSK: WPA offers a Personal mode of operation. In the Personal mode of operation, a pre-shared key is used for authentication. WPA-PSK allows you to gain access to a secured wireless network that the station and the access point use the same pre-shared key to authenticate. You must type a mixture of numbers and letters in the Pre-shared key section of this menu. You may input either 8-63 ASCII characters or 64 HEX characters. Choose WPA-PSK if needed from Authentication Mode.
WPA2: WPA2 provides a stronger encryption mechanism than WPA. WPA2 is the second generation of WPA security, providing personal and enterprise users with a high level of assurance that only authorized users can access to their wireless network. There is no difference between WPA and WPA2. The only difference is that WPA2 provides a stronger data encryption via the AES, contrast to WPA, which uses Temporal Key Integrity Protocol (TKIP). Choose WPA2 if needed from Authentication Mode.
WPA2-PSK: Like WPA, WPA2-Personal offers authentication via a pre-shared key. Pre-shared key is usually used for Personal authentication. Personal mode requires only an access point and client on the network. Similarly, you need to type a mixture of numbers and letters in the Pre-shared key section of this menu. You may input either 8-63 ASCII characters or 64 HEX characters. Choose WPA2-PSK if needed from Authentication Mode.
3.2.3.1 Encryption Mode WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1X. WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP. The encryption mechanism used for WPA(2) and WPA(2)-PSK are the same.
connect to a network. Other WPA2 authentication features that are different from WPA include key caching and pre-authentication. After you select the EAP type, you need to click Certification Tab to make advanced setting. The following describes configuration of each available EAP type. TLS: Clicking the Certification tab for TLS shows the following menu. TLS requires the entry of Certificate Information and Login Information for mutual authentication.
Figure 3.1 Figure 3.2 PEAP requires the use of Certificate Information and User Information. This utility will automatically identify Certificate Information and Login Information for users to configure PEAP easily. You only need to enter User Name and Password in the User information filed to authenticate (Figure 3.1). If you click the “Verify Server Certificate” check box, you are able to choose one of User Certificate from the drop-down menu.
TTLS: Clicking the Certification tab for TTLS shows the following menu. TTLS requires the mutual authentication between station and access points. You must present a User Name and Password in the User Information field that will be verified by TTLS-capable server. This mutual authentication ensures that only authorized users are allowed access to the network. 3.3 Authentication Type The IEEE 802.11b/g standard describes a simple authentication method between the wireless stations and AP.
Chapter 4 4.1 Use the Wireless LAN Utility The WLAN Utility enables you to make configuration changes and perform user-level diagnostics on your IEEE802.11n Wireless LAN USB Adapter in the Windows XP/2000 operating system environments. The WLAN Utility consists of window with 3 items for you to monitor and configure the IEEE802.11n Wireless LAN USB Adapter: Configuration, Site Survey and About. Configuration The Configuration item allows you to modify the configuration parameters for the IEEE802.
profile. With a profile activated, each time you start the wireless LAN adapter, it automatically scans for the specific SSID and joins that network with the pre-defined wireless security settings. To create the profile, go to the Profile field, type a profile name and set the corresponding parameters. If one of the profiles is no longer used, you may remove it by clicking the Delete button. After changing parameters, save the profile and click the Apply button to take effect.
Wireless Mode The wireless Mode supports three options 802.11B, 802.11B/G, and 802.11B/G/N. Power Saving Mode The Power Save option is designed to conserve battery life of you computer. When Power Save is enabled, your IEEE 802.11n Wireless LAN USB Adapter will go into sleep mode to minimize power consumption. Note: When power saving mode is enabled, the Access Points you use need to support power saving as well so that the communication can be established.
the wireless network. If your IEEE 802.11n Wireless LAN USB Adapter often transmits large files in the wireless network, you can enable the Fragmentation Threshold by clicking the Enable button and the mechanism will split the packet. The default value is Disable. Status: The Status field on the Configuration menu provides the following information. State: When operating in Infrastructure mode, this field shows the MAC address of the Access Point with which the IEEE 802.
You can click the Rescan button to force the radio to rescan all available channels. If your link quality or signal strength is poor, rescanning can be used to push the radio off a weak Access Point and search for a better link with another Access Point. Site Survey: Use the Site Survey screen to scan for and connect to a wireless network automatically. By clicking the Rescan button, the AP Browser can display Access Points around the working environment.
