Wireless clients associating to any Access Point must have the same SSID. The default setting is ANY, which allows your IEEE 802.11n Wireless Network USB Adapter to automatically associate to any Access Point (Infrastructure mode) in the vicinity of your wireless adapter. The ESS ID can be set up to 32 characters and is case sensitive. 3.1.2 Channel A radio frequency used by a wireless device is called a channel. 3.1.3 Transmit Rate (Tx Rate) The IEEE 802.11n Wireless Network USB Adapter support various transmit (data) rate. It includes Auto, 1 or 2 Mbps, 5.5 Mbps, 11 Mbps and up to 300Mbps. In most networking scenarios, the factory default “Auto” setting proves the most efficient. This setting allows your IEEE 802.11n Wireless Network USB Adapter to operate at the maximum transmit (data) rate. When the communications quality drops below a certain level, the Wireless Network USB Adapter will automatically switch to a lower data rate. Transmission at lower data speed is usually more reliable. However, when the communications quality improves again, the Wireless Network USB Adapter will gradually increase the transmit (data) rate again until it reaches the highest available transmit rate. Note: Actual speeds attained also depend on the distance from the AP, noise, etc. 23 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 802.11n Wireless LAN USB Adapter, the wireless communication is accessible to any wireless networking device that is in the coverage area. 24 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 communication 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 one time. The Key index field allows you to specify the key index you desire to use for transmitting data on your wireless LAN. You can change the default key by clicking on the up or down arrow and make sure the default key is set up exactly the same on the Wireless LAN stations as they are on the wireless Access Point. For 64bit encryption you may choose: Alphanumeric: entering 5 characters (case sensitive) ranging from “a-z”, “A-Z” and “0-9” (e.g. MyKey). Hexadecimal: entering 10 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (e.g. 11AA22BB33, showed as below). For 128bit encryption you may choose: Alphanumeric: entering 13 characters (case sensitive) ranging from “a-z”, “A-Z” and “0-9” (e.g. MyKey12345678). Hexadecimal: entering 26 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (e.g. 00112233445566778899AABBCC). 25 3.2.2 IEEE 802.1x The IEEE 802.1x standard outlines enhanced security methods for both the authentication of 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. The type of authentication you use depends on the RADIUS server and an intermediary AP that supports IEEE 802.1X. You must first have a wired connection to the network and obtain the certificate from a certificate authority (CA). A certificate can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner. 3.2.3 WPA (2) Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 is a wireless security standard that defines stronger encryption, authentication and key management than WPA. WPA: Allows you to gain access to a more secured wireless network that requires mutual authentication between client and access point with a Radius authentication server or other authentication server on the network. WPA uses 802.1X and Extensible Authentication Protocol (EAP) for authentication. WPA offers Enterprise and individual needs to meet the different market segments. This product supports various EAP types (TLS and PEAP), which require different credential authentication. In order to access the wireless network, you must select EAP type your service provider supplied in the section of IEEE802.11X Authentication. Choose WPA2 if needed from Authentication Mode. 26 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. 27 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. 28 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. The only difference between them is that WPA(2)-PSK uses a simple common password, instead of user specific credentials. The common password approach makes WPA(2)-PSK susceptible to brute-force password-guessing attacks but it’s still an improvement over WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption keys. 3.2.3.2 IEEE 802.1X Authentication WPA and WPA2 apply IEEE 802.1X and Extensible Authentication Protocol (EAP) to authenticate wireless stations using an external RADIUS database. WPA2 reduces the number of key exchange messages from six to four (CCMP 4 way handshake) and shortens the time required to connect to a network. Other WPA2 authentication features that are different from WPA include key caching and pre-authentication. 29 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. This utility will auto-detect the Certificate Information for you to configure TLS easily. You only need to enter the Login Name in the Login information filed to authenticate. If you desire to use the Server Certificate manually, you can click the check box next to “Verify Server Certificate” and choose the usable selection in the User Certificate field using drop-down menu. User Certificated: select one of user certificates you have enrolled. TLS is used to create a secure tunnel through which authentication and encryption keys can be passed and require server and client side keys. To save the information you entered in the appropriate field, click the OK button. Otherwise, click the Cancel button to close the menu. If you want to return to select other EAP type, click the Security tab. PEAP: Clicking the Certification tab for PEAP displays the following menu. 30 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. If you click the “Verify Server Certificate” check box, you are able to choose one of User Certificate from the drop-down menu. Furthermore, you need to input User Name and Password in the User Name field on the screen. To save the information you entered in the appropriate field, click the button. Otherwise, click the button or button to close the menu. If you want to return to select other EAP type, click the tab. 31 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. Two authentication types are defined: Open system mode and a Shared key mode. z Open system mode is implemented for ease-of-use and when security is not an issue. It requires NO authentication, since it allows any device to join a network without performing any security check. The wireless station and the AP do not share a secret key. Thus the wireless stations can associate with any AP and listen to any data transmitted plaintext. z Shared key mode involves a shared secret key to authenticate the wireless station to the AP. It requires that the station and the access point use the same WEP key to authenticate. This basically means that WEP must be enabled and configured on both the AP and the other wireless stations with a same key. Shows as below: 32 3.3 Wi-Fi Protected Setup (WPS) Wi-Fi Protected Setup (WPS) is a standard for easy and secure establishment of a wireless home network, defined by the Wi-Fi Alliance. The goal of the WPS is to simplify the process of connecting any home device to the wireless network. The WPS protocol defines two types of devices in a network: z Registrar: A device with the authority to issue the credentials to enroll new clients on the network. A Registrar may be integrated into an AP, or it may be separate from the AP. z Enrollee: A device seeking to join a wireless LAN network. The WPS gives users a variety of setup options. It uses PBC (Push Button Configuration) and PIN (Personal Identification Number) to enable user to automatically configure network names and strong data encryption and authentication. For the PBC mode, the Access Point and the wireless client just simply push a hardware button or software button. After pushing Access Point WPS button, the client must push software button within 2 minutes. For the PIN mode, input the same PIN number for the Access Point and for the wireless client. After the connection is made successfully, the wireless client will be able to receive the data from the Access Point such as SSID, wireless security, and etc. 33 Chapter 4 Configure by Wireless Utility This chapter provides more detail introduce for using the utility to configure the wireless adapter. 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 Vista/XP/2000 operating system environments.

To close the menu, click to let you monitor the more Profile The Profiles item allows you to add a new profile or to set values for all parameters by editing a previously defined profile. Clicking this tab displays the following screen: 35 Press to create a new profile, and configure all the parameters following the steps below. Step1. Input the Profile Name, Network (SSID), and select Network type (Infrastructure/Adhoc) when Add a profile progress start. 36 Step2. To protect 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. To activate security enable, click the check box next to Security Enable. A Privacy Configuration window will then appear. Note: Privacy Configuration consists of specifying Security and Certification. Refer to Chapter 3 for how to configure security settings. Step3. Setup the TCP/IP settings. When you check the box, you can choose to obtain the IP address from the DHCP server on your network automatically. Or you can specify IP address manually but it must be an unique IP address to your network. 37 Step4. The WLAN Utility also offers the advanced configuration for user to set the IEEE 802.11n Wireless LAN USB Adapter under certain network environment. These advanced options include Power Save Mode, Wireless Mode, Adhoc Channel, RTS Threshold, and Fragmentation Threshold. Note: Under Vista OS, these parameters are not allowed to be configures the parameters. 38 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. RTS Threshold RTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. If the “Hidden Node” problem is an issue, please specify the packet size. The RTS mechanism will be activated if the data size exceeds the value you set. It is highly recommended that you set the value ranging from 0 to 2347. The default value is 2347, that means disable RTS mechanism. If you set to 0, that means always enable RTS mechanism. 39 Note: Enabling RTS Threshold would cause redundant network overhead that could negatively affect the throughput performance instead of providing a remedy. Fragament Threshold Fragmentation mechanism is used for improving the efficiency when high traffic flows along in the wireless network. If your IEEE 802.11n Wireless LAN USB Adapter often transmits large files in the wireless network. The range is from 256 to 2346, and the default value is 2346. Step5.
