You may refer to the following 3 examples of Surveying the Network Neighborhood, File Sharing and Using the Shared Folder. 8.1 Surveying the Network When multiple base stations are up and running in your wireless network, you can use the procedure described below to display the other computers:
Double-click My Network Places to display all stations in your Microsoft Windows Network Group. To display other workgroups in the network environment, double-click Entire Network. If there is a second network operating system running in your network environment (for example a Novell NetWare network), the Entire Network window will also display available servers running under the second network operating system. If you click on these servers, you may be asked to enter your user name and password that applies to the other network operating system. If you cannot find it, verify whether the other wireless computers are:
Powered up and logged on to the network. 36 8. Network Application Configured to operate with identical Microsoft Network settings concerning:
?? Networking Protocol.
?? Wireless Network Name. To enable the sharing of Internet access, you should set your WLAN mode as Infrastructure and connect to the access point. 8.2 File Sharing 802.11g USB 2.0 Adapter allows the sharing of files between computers that are logged onto the same wireless network. If you want to share your folder My Documents with other computers of the wireless network, please highlight the folder My Documents and drag it to Shared Documents folder. 37 8. Network Application Sharing files in the IEEE802.11g wireless network will be like sharing files on a wired LAN. 8.3 Using the Shared Folder If you would like to access a shared folder stored in other stations of same network, please follow the process below:
Double-click the My Network Places icon, and then double-click the computer where the shared folder is located. Double-click the folder you want to connect to. Now you may open the needed file(s). Note!
If a password is required, the Windows will prompt a password column to you. Then you need to enter the password that had been assigned to this shared folder. 38 9 Item Frequency Range 9. Specification Description

PEAP: Protected Extensible Authentication Protocol is a two-phase authentication like TLS. In the first phase the Authentication Server is authenticated to the Supplicant. Using TLS, a secure channel is established through which any other EAP-Type can be used to authenticate the Supplicant to the Authentication Server during the second phase. A certificate is only required at the Authentication Server. PEAP also supports identity hiding where the Authenticator is only aware of the anonymous username used to establish the TLS channel during the first phase but not the individual user authenticated during the second phase. SSID: Name of wireless network. TLS: TLS is an EAP-Type for authentication based upon X.509 certificates. Because it requires both the Supplicant and the Authentication Server to have certificates, it provides explicit Mutual Authentication and is resilient to man-in-the-middle attacks. After successful authentication a secure TLS link is established to securely communicate a unique session key from the Authentication Server to the Authenticator.
- WPA: Wi-Fi Protected Access is a replacement security standard for WEP. It is a subset of the IEEE 802.11i standard being developed. WPA makes use of TKIP to deliver security superior to WEP. 802.1X access control is still employed. The Authentication Server provides the material for creating the keys. 40
