Consider the following scenario.
Windows cannot connect to access_point.
This problem occurs when you try to connect to a wireless network access point that uses shared-mode network authentication.
The Wireless service in Windows Vista performs a scan for available wireless network access points. The results of the scan are shown in the list of available networks in the Wireless Network Connection dialog box. Access points broadcast an identifying beacon that uses a format that is defined by the IEEE 802.11 standard. This format does not include the authentication mode that is used by the access point. Because most access points use open authentication, the wireless service assumes that all access points use open authentication for connections.
Note For networks that do not use Wi-Fi Protected Access (WPA), we recommend that you use open authentication together with WEP encryption instead of using shared authentication with or without encryption. This helps provide additional security for your wireless network. If you use a shared key instead of open authentication together with WEP encryption, an unauthorized user could decrypt the shared key to obtain access to all the computers in your wireless network.
To work around this problem, manually create a network profile by using the Manually Connect to a Wireless Network Wizard and by selecting shared-mode network authentication. To do this, follow these steps:
