Wireless LAN API KB918997 FroWindows XP SP2: un sous-ensemble de la fonctionnalité Native Wifi API d



Wireless Zero Configuration (WZC), also known as Wireless Auto Configuration, or WLAN AutoConfig, is a wireless connection management utility included with Microsoft Windows XP and later operating systems as a service that dynamically selects a wireless network to connect to based on a user's preferences and various default settings.[1][2] This can be used instead of, or in the absence of, a wireless network utility from the manufacturer of a computer's wireless networking device. The drivers for the wireless adapter query the NDIS Object IDs and pass the available network names (SSIDs) to the service. The service then lists them in the user interface on the Wireless Networks tab in the connection's Properties or in the Wireless Network Connection dialog box accessible from the notification area. A checked (debug)[3] build version of the WZC service can be used by developers to obtain additional diagnostic and tracing information logged by the service.




Wireless LAN API KB918997 FroWindows XP SP2




Initially, there was no Wireless LAN API in Windows XP for developers to create wireless client programs and manage profiles and connections. After the release of Windows Vista, Microsoft released KB918997,[4] which includes a Wireless LAN API for Windows XP SP2. It was later integrated into Windows XP Service Pack 3.


Best Practice: Just activate the Disable background scan tweak and leave the other tweaks untouched. If you experience problems, you can also try enabling streaming mode. Disabling autoconfig is notrecommended (it's pretty much the same as disabling background scan, but you won't see any wireless networks in Windows).


WLAN Optimizer starts fine, but it doesn't work! First of all, there has to be at least one connected wireless adapter. If you have a stable connection and experience just one lag per minute, try another combination of tweaks. Sometimes just disabling background scan doesn't work. Additionally enabling streaming mode can help. Every user has to find out the best combination for himself by trial and error. I recommend disabling background scan first. If this doesn't help try a combination with the other tweaks. If there isn't any working combination for you, you should try another driver. One user reported driver version 2.1.0.0 as a solution for problems with his RT61-chipset and WLAN Optimizer 0.10 Alpha.


Installing this set of application programming interfaces (APIs) will enable you to create applications that can manage wireless LAN profiles and connectivity on Microsoft Windows XP Service Pack 2 (SP2) using the native wireless functionality in Windows, called Wireless Zero Configuration (WZC) service.


Ultimately, this script will make use of the "WLAN.exe" tool on Windows XP and make use of the "netsh.exe" tool in Windows Vista and later in order to export all wireless profiles to a flash drive in a folder called "Backup\NameOfComputer\WirelessProfiles". Each Profile will be named as the "SSID.xml" You may then use the restore functionality to import all retrieved profiles back into the system.


So now when you import the reg file, it doesn't replace the registry entry, it adds yet another REG_BINARY for the same wireless network. So you still have to delete the generated REG_BINARY item that came after the WLAN import, and then your EAP type settings will take effect immediately.


I'm looking for a solution like this for Windows 7 as I'm trying to find a way to deploy or automate the process of adding pre-configured wireless profile. Although I successfully exported the profile from a previously configured machine vianetsh wlan export profile name="company-network" folder="H:\wireless-profile"


Lastly, I'm aware that Windows allows one to copy an already configured wireless profile to a USB flash drive, but its my understanding that the `setupSNK.exe` that gets created doesn't accept any of the standard silent/quiet switches. Furthermore, the file won't even launch when its not run from a flash; it simply doesn't launch or it launches and immediately quits.


Windows 2000 wireless support did not support seamless roaming and auto-configuration. Windows XP's Wireless Zero Configuration service supports automatic wireless network configuration with re-authentication when necessary thus providing seamless roaming capability and setting the preferred order of connections. In the absence of a wireless access point, Windows XP can set up an ad hoc wireless network. There is native support for WPA and WPA2 authentication in infrastructure networks with the latest service packs and/or updates applied. Windows XP includes a Wireless Network Setup Wizard which supports the Windows Connect Now: USB Flash Drive (WCN-UFD) method to ease setting up the wireless network for inexperienced users.


Beginning with Windows XP SP2, the audio volume taper is stored in the registry for on-screen keyboard and remote control applications and can be customized by third parties,[151] and Internet Explorer has improved Group Policy settings support beyond security settings. (KB918997) for Windows XP SP2 and Windows XP SP3 add a Wireless LAN API for developers to create wireless client programs and manage profiles and connections. There is IEEE 802.1X support for wireless and wired connections. In case, a PKI is not available to issue certificates for a VPN connection, there is support for preshared key for IKE authentication.[152] With KB912761 for Windows XP SP2 or on Windows XP SP3, users can configure whether EFS generates a self-signed certificate when a certificate authority is unavailable. Windows Firewall beginning with Windows XP SP2 also supports IPv6 stateful filtering. Applications and tools such as the Telnet client, FTP client, ping, nslookup, tracert, DNS resolver, file and print sharing, Internet Explorer, IIS have been updated to support IPv6. Windows XP SP1 and greater support the downloadable WIA Library v2.0 which provides access to WIA functionality through programming languages and scripting environments that support OLE Automation. 2ff7e9595c
