Tab This Tab contains all Authentication and Encryption settings Authentication:

OpenWith the Open method, every wireless station can request authentication.

SharedWith the Shared authentication, the station requesting authentication must provide a secret key (which can be obtained from network administrator) using a secure channel (independent of the 802.11 wireless communications channel).

LEAP(Light Extensible Authentication Protocol) is an EAP authentication method used primarily on Cisco Aironet wireless networks. This protocol encrypts transmitted data using dynamically generated WEP keys, and supports two way authentications.

WPA and WPA2IEEE 802.1x protocol is used for authentication and AES or TKIP for encryption.

WPA PSK and WPA2 PSKStation requesting authentication must provide a WPA Preshared Key. AES or TKIP are used for encryption.

Authentication: Open and Shared AuthenticationChange authentication method. EncryptionSelect None or WEP. Use 802.1xCheck this option to use IEEE 802.1x for authentication. IEEE 802.1x supports full user authentication and control. This will also enable 802.1x Tab, where 802.1x can be configured. WEP Key / Key#1 4When you select WEP encryption or Shared authentication without 802.1x, you need to enter a correct WEP key.

If a 64-bit WEP key is used, enter 10 Hexadecimal characters or 5 16 http://www.Lcom.com

AES (Advanced Encryption System) uses symmetrical 128-bit data block encryption.

TKIP (Temporal Key Integrity protocol) uses stronger encryption algorithms and MIC (Message Integrity Check) to provide security against hackers. WPA and WPA2 use IEEE 802.1x protocol for authentication. After selecting encryption method go to 802.1x Tab, where 802.1x settings can be configured.

All information can be obtained from wireless network administrator. Appearance of this Tab depends on options selected from EAP method and Tunnel Authentication lists.

PEAPProtect Extensible Authentication Protocol. PEAP transports secured authentication data by using tunneling between PEAP clients and an authentication server. PEAP can authenticate wireless LAN clients using only server-side certificates, thus simplifying the implementation and administration of secure wireless network.

TLS/Smart Card Transport Layer Security. Provides for certificate-based and mutual authentication of the client and the network. It relies on client-side and server-side certificates to perform authentication and can be used to dynamically generate user-based and session-based WEP keys to secure subsequent communications between the WLAN client and the AP.

TTLSTunnel Transport Layer Security. This security method provides for certificate-based, mutual authentication of the client and network through an encrypted channel. Unlike EAP-TLS, EAP-TTLS, it requires only server-side certificates.

EAP-FASTFlexible Authentication via secured Tunneling. It was developed by Cisco. Instead of using a certificate, mutual authentication is achieved by means of a PAC (Protected Access Credential) which can be managed dynamically by the authentication server. The PAC can be provisioned

(distributed on time) to the client either manually or automatically. Manual provisioning is delivered to the client via disk or secured network distribution method. Automatic provisioning is an in-band, over the air, distribution. For tunnel authentication, only support Generic Toke Card authentication now.

MD5-ChallengeMessage Digest Challenge. Challenge is an EAP authentication type that provides base-level EAP support. It provides for only one-way authentication, there is no mutual authentication of wireless client and the network. 19

The Wireless USB Adapter does not work properly.

Reinsert the Wireless Adapter into your PCs USB port.

Right click on My Computer and select Properties. Select the device manger and click on Network Adapter. You will find the Adapter if it is installed successfully. If you see the yellow exclamation mark, the resources are conflicting. You will see the status of the Adapter. If there is a yellow question mark, please check the following:

Make sure that your PC has a free IRQ(Interrupt Request, a hardware interrupt on a PC).

Make sure that you have inserted the right adapter and installed the proper driver. If the Adapter does not function after attempting the above steps, remove the adapter and do the following:

32 2. http://www.Lcom.com

Uninstall the driver software from your PC.

Restart your PC and repeat the hardware and software installation as specified in this User Manual. I cannot communicate with other computers linked via Ethernet in the Infrastructure configuration.

Make sure the power of the PC with Adapter associated is on.

Make sure that your Adapter is configured on the same channel and with the same security options as with the other computers in the Infrastructure configuration. 3. What should I do when the computer with the Adapter installed is unable to connect to the wireless network and/or the Internet?

Check the LED indicators from the broadband modem, see if LED indicating normal activity. If not, there may be problem with the broadband connection.

Check the LED indicators on the wireless router or AP to see if they are functioning properly. If not, check if the AC power and Ethernet cable are firmly connected.

Check the IP address, subnet mask, gateway and DNS settings are

correctly entered for the network. In Infrastructure mode, make sure the same Service Set Identifier (SSID) is specified on the settings for the wireless clients and access points. In Ad-Hoc mode, both wireless clients will need to have the same SSID. Please note that it might be necessary to set up one client to establish a BSS (Basic Service Set) and wait before setting up other clients. This prevents several clients from trying to establish a BSS at the same time, which can result in multiple singular BSSs being established, rather than a single BSS with multiple clients associated to it.

Check if the Network Connection for the wireless client is configured

properly. If Security is enabled, make sure the correct encryption keys are entered on both the Adapter and the access point. 33 Appendix A: Specification http://www.Lcom.com Standards Compliance Chipsets Solution Frequency Band Transmission Power Transmission Rate Sensitivity Antenna Type Security Systems USB Temperature Network Management System OS Support Warranty IEEE 802.11b/g/n USB v1.0/1.1/2.0 RT3070L America/FCC2.412~2.462 GHz (11 channels) Europe CE/ETSI2.412~2.472 GHz (13 channels) Japan : 2.412~2.484 GHz (14 channels) 30dBm IEEE802.11b: 11 Mbps IEEE802.11g: 54 Mbps IEEE802.11n 150 Mbps IEEE 802.11n: -90dBm @ HT20 IEEE 802.11g: -92dBm @ 54Mbps IEEE 802.11b: -95dBm @ 11Mbps External 4dBi Dipole Antenna(Optional) 64/128-bit WEP,WPA,WPA2,TKIP,AES,Cisco CCX,WAPI-CERT USB 2.0 with 5m cable 32~122F (0 ~50C) Windows 2000/XP/Vista, Windows 7, Linux, Mac X One year limited 34
