Supplicant: Wireless Network PC Card Here is the setup for the Wireless Network PC Card under Windows XP, which is the only Operating System that our driver supports for 802. 1x. Microsoft is planning on supporting 802. 1x security in all common Windows Operating System including Win98SE/ME/2000 by releasing Service Pack in 2003. 40 Please note that the setup illustration is based on our 22Mbps wireless PC Card. Go to Start > Control Panel double-click on "Network Connections" right-click on the Wireless Network Connection that you use with our 22Mbps wireless PC Card. Click "Propert ies" to open up the Properties setting window. 41 5. Click on the "Wireless Network" tab. 42 6. Click "Properties" of the available wireless network, which you wish to connect or configure. Please note that if you are going to change to a different 802. 1x authentication EAP method, i. e. switch from using MD5 to TLS, , you must remove the current existing wireless network from your Preferred networks first, and add it in again. To configure for using TLS authentication method, please follow steps 7 ~ 25. Please follow steps 26 ~ for using MD5 authentication method. 43 TLS Authentication 7. Select "The key is provided for me automatically" option 8. Click "OK" to close the Wireless Network Properties window. 44 9. 11. Click "Authentication" tab Select "Enable network access control using IEEE 802. 1x" option to enable 802. 1x authentication. Select "Smart Card or other Certificate " from the drop-down list box for EAP type. 12. Click "OK" to close the Wireless Network Connection Properties window, thus make the changes effective. The wireless client configuration in the zero-configuration utility provided in Windows XP is now completed for TLS configuration. Before you can enable IEEE 802. 1x authentication and have wireless client authenticated by the Radius server, you have to download the certificate to your local computer first. 45 TLS Authentication ­ Download Digital Certificate from Server In most corporations, it requires internal IT or MIS staff's help to have the certificated downloaded to your local computer. One of the main reasons is that each corporation uses its own server systems, and you will need the assistance from your IT or MIS for account/passwo CA server location and etc. The rd, following illustration is based on obtaining a certificate from Windows 2000 Server which can act as a CA server, assuming you have a valid account/password to access the server. Connect to the server and ask for access, and the server will prompt you to enter your user name and password. Enter your user name and password, then click "OK" to continue. Please note that we use IP addresses for connection with the server for our illustration, and the IP of the server is 192. 168. 1. 10. After successful login, open up your Internet Browser, and type the following in the address field. http://192. 168. 1. 10/certsrv This is how we connect to the Certificate Service installed in Windows 2000 server. 46 16. Now we are connected to the Certificate Service. Select "Request a certificate ", and click "Next" to continue. 47 17. [. . . ] During transmission, the PSDU shall be appended to a PLCP preamble and header to create the PPDU. Two different preambles and headers are defined as the mandatory supported long preamble and header which interoperates with the current 1 and 2 Mbit/s DSSS specification as described in IEEE Std 802. 11-1999, and an optional short preamble and header. At the receiver, the PLCP preamble and header are processed to aid in demodulation and delivery of the PSDU. The optional short preamble and header is intended for application where maximum throughput is desired and interoperability with legacy and non-short-preamble capable equipment is not consideration.
