2.6.1. Configuring IEEE 802.11b-Related Settings
Before the TCP/IP networking system of a wireless client computer can communicate with other hosts,
the underlying wireless link must be established between this wireless computer and a deployed AP or
the wireless access gateway’s built-in AP.
To establish a wireless link to an AP:
1. Launch the configuration/monitoring utility provided by the vendor of the installed WLAN NIC.
2. Use the utility to make appropriate operating mode , SSID and WEP settings.
NOTE: A wireless client computer must be in infrastructure mode, so that it can associate with a
wireless access point.
NOTE: The SSID of the wireless client computer and the SSID of the deployed APs must be identi-
cal. Or, in case the SSID broadcasts capability of the deployed APs is enabled (by default), the SSID
of the wireless client computer could be set to “any”.
NOTE: Both the wireless client computer and the deployed APs must have the same WEP settings for
them to communicate with each other. Therefore, unless IEEE 802.1x EAP-TLS, which supports dy-
namic WEP key distribution, is used, it’s strongly suggested not to enable WEP functionality of the
deployed APs for
hotspot applications.
NOTE: If IEEE 802.1x authentication is to be used, see the IEEE 802.1x-related white papers on the
accompanying CD-ROM for more information on setting up the wireless client computer.
2.6.2. Configuring TCP/IP-Related Settings
If a wireless user use a Windows computer, he/she can use Windows Network Control Panel App-
let to change the TCP/IP settings of his/her computers, so that the IP addresses of the client computers
and the IP address of the gateway are in the same IP subnet. If the access gateway is to be used in a
hotspot, the client computers must be set to obtain IP addresses automatically by DHCP.
NOTE: Set the client computers to obtain IP addresses automatically by DHCP.
NOTE: Configure the client computers so that Web browsing is not through any Web Proxy servers;
otherwise the Web redirection-based authentication will not work properly.
If a client computer is already set to obtain an IP address automatically, you can use the Win-
dows-provided tool,
WinIPCfg.exe (on Windows 9x) or IPConfig.exe (on Windows 2000), to
re-obtain an IP address from the gateway. WinIPCfg.exe is a GUI program, and has command but-
tons for releasing the current IP address and re-obtaining an IP address. IPConfig.exe is a com-
mand-line program, and the /release option releases the current IP address and the /renew option
triggers the Windows DHCP client subsystem to re-obtain an IP address.
2.7. Confirming the Settings of the WLAN Hotspot
Access Gateway and Client Computers
To make sure whether you have correctly set up the gateway for Web redirection-based authentication
or not, follow the procedure below:
