For Windows XP, there is a “Windows Zero Configuration Tool” by default for you to setup wireless clients. If you want to use the Utility of the USB adapter, please follow one of the ways as below. A. Double-click the icon. B. Click “Advance”. C. Uncheck “Use Windows to configure my wireless network settings”.
3 Configuration Utility The Client Utility is a user-mode utility designed to edit and add profiles for, as well as display and diagnostics pertaining to a selected wireless USB adapter. 3.1 Wireless Connection Status When you open the Configuration Utility, the system will scan all the channels to find all the access points/stations within the accessible range of your card and automatically connect to the wireless device with the highest signal strength.
3.2 Profile Management Parameter Description New To add a new configuration profile, click New on the Profile Management tab. To modify a configuration profile, select the configuration from the Profile list and click the Modify button. Modify In the Atheros Client Utility, access the General tab by clicking New or Modify on the Profile Management tab. Edit the fields in the General tab to configure the configuration profile. Make sure to also edit the Security and Advanced tabs.
Order Profiles 3.3 3. Browse to the directory to export the profile to. 4. Click Save. The profile is exported to the specified location. Including a profile in the auto selection feature allows the wireless adapter to automatically select that profile from the list of profiles and use it to connect to the network. Diagnostics The client utility includes a number of tools to display current diagnostics and status information.
3.4 Security This Chapter describes setting up security using the Atheros Client Utility(ACU). While using the Atheros USB wireless network adapter, encryption data can protect its as it is transmitted through the wireless network. While using the Atheros USB wireless network adapter, encrypting data can protect its privacy as it is transmitted through the wireless network. The ACU allows connection profiles of: No security (not recommended) Link encryption/decryption is disabled, no keys are installed.
This is because the WEP keys of all devices that are to communicate with each other must match. Authentication Process Enabling EAP on the access point and configuring the USB device to LEAP, EAP-TLS, PEAP (EAP-GTC), or PEAP (EAP-MSCHAP V2) authentication to the network occurs in the following sequence: 1. The client associates to an access point and begins authentication. 2.
that Allow Association to Mixed Cells is checked on the Security Tab to allow association. Pre-Shared Key(Static WEP) Enables the use of pre-shared keys that are defined on both the access point and the station. To define pre-shared encryption keys, choose the Pre-Shared Key radio button and click the Configure button to fill in the Define Pre-Shared Keys window.
Using EAP-TLS Security Important Note: To use EAP-TTLS security, the machine must already have the EAPTTLS certificates downloaded onto it from a Certificate Authority (CA). Please check with your IT administrator. To use EAP-TLS security In the Atheros Client Utility, access the Security tab in the Profile Management window. 1. On the Security tab, choose the WPA radio button. OR: On the Security tab, choose the 802.1x radio button. 2. Choose EAP-TLS from the drop-down menu.
Using EAP-TTLS Security Important Note: To use EAP-TTLS security, the machine must already have the EAPTTLS certificates downloaded onto it from a Certificate Authority (CA). Please check with your IT administrator. To use EAP security In the Atheros Client Utility, access the Security tab in the Profile Management window. 1. On the Security tab, choose the WPA radio button. OR: On the Security tab, choose the 802.1x radio button. 2. Choose EAP-TTLS from the drop-down menu.
Using PEAP-GTC Security Important Note! To use PEAP (EAP-GTC) security, the server must have WPA-PEAP certificates, and the Certificate Authority (CA) server properties must already be set up. Please check with your IT administrator. To use PEAP security, access the Security tab in the Profile Management window. 1. In the ACU, edit the security settings by clicking New or Modify on the Profile Management tab. 2. Choose a profile to edit, or name the new profile in the Profile Management window.
7. Choose Token or Static Password, depending on the user database. Note that Token uses a hardware token device or the Secure Computing SofToken program (version 1.3 or later) to obtain and enter a one-time password during authentication. 8. Click Advanced and: – Leave the server name field blank for the client to accept a certificate from any server with a certificate signed by the authority listed in the Network Certificate Authority drop-down list.
5. 6. Specify a user name for inner PEAP tunnel authentication: – Check Use Windows User Name to use the Windows user name as the PEAP user name. – OR: Enter a PEAP user name in the User Name field to use a separate user name and start the PEAP authentication process. Click Advanced and: – Leave the server name field blank for the client to accept a certificate from any server with a certificate signed by the authority listed in the Network Certificate Authority drop-down list.
Using LEAP Security Important Note! LEAP security requires that all infrastructure devices (e.g. access points and servers) are configured for LEAP authentication. Check with the IT manager. To use security In the Atheros Client Utility, access the Security tab in the Profile Management window. Configuring LEAP: The LEAP authentication type uses Cisco Key Integrity Protocol (CKIP) and MMH message integrity check (MIC) for data protection.
o Check Use Windows User Name to use the Windows user name as the LEAP user name. o OR: Check Manually Prompt for LEAP User Name and Password to manually login and start the LEAP authentication process. Select to Use Saved User Name and Password by choosing the radio button: o Specify the LEAP user name, password, and domain to save and use. 3. Enter the user name and password. 4. Confirm the password. 5.
5. Enter the WPA passphrase (for ASCII text, enter 8-63 characters, for hexadecimal, enter 64 characters). Click OK. 6. Click OK and enable the profile. 3.4.3 Pre-Shared Encryption Keys To use Pre-Shared Key (static WEP) security In the Atheros Client Utility, access the Security tab in the Profile Management window. 1. In the ACU, edit the security settings by clicking New or Modify on the Profile Management tab. 2. Choose a profile to edit, or name the new profile in the Profile Management window.
configuration security. At least one Shared Key field must be populated to enable security using a shared key. Click on the radio button to set the key as the default encryption key. WEP Key Size 4. Defines the size for each encryption key. The options include: o 64- bit (enter 10 digits for hexadecimal, 5 ASCII characters) o 128- bit (enter 26 digits for hexadecimal, 13 digits for ASCII) o 152-bit (enter 32 digits hexadecimal, 16 digits for ASCII) Click OK for the changes to take effect.
4 Troubleshooting This chapter provides solutions to problems usually encountered during the installation and operation of the adapter. 1. For Windows 98SE computers, if the Atheros Client Utility fails to load after properly installation, click on the windows “Start” button on your toolbar, select the “run” button, and enter “C:\Windows\system\aegis2.exe” into the dialog box, then press enter, a dialog box will pop up, please select “install” then press “enter”. 2.
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 802.11g standard requires backward compatibility with 802.11b. The standard specifically calls for: A. A new physical layer for the 802.11 Medium Access Control (MAC) in the 2.4 GHz frequency band, known as the extended rate PHY (ERP).
8. What is TKIP? TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security, especially the reuse of encryption keys. TKIP is involved in the IEEE 802.11i WLAN security standard, and the specification might be officially released by early 2003. 9.
looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
