For example, "use Wi-Fi Protected Access 2 (WPA2) security" is a technology best practice, whereas "train employees not to connect to ad hoc WLANs" is a procedural best practice.

This article describes the changes to protocols and core networking components, wireless and 802.1X-authenticated wired technologies, and network infrastructure components and services in Windows Server 2008 and Windows Vista.
I have 2 old laptops both running on Windows XP, which I am trying to connect via WIFI to a Belkin router. One works fine but the other will not accept the network key which I know to be correct.
I can see that the "properties" of the connections are different but can't see how to change them.
Make sure that the WLAN light is on or flashing, check the settings whether the SSID is broadcasted or hide. When you connect to a wireless network, the settings and profile of that specific network is saved on your computer so that you won’t have to re-enter your network credentials, such as the wireless security key to connect the next time.
Change the Wireless Network Name and Channel, save and reboot. Try to change different security type to see whether you meet the same problem. Below are FAQs about how to remove wireless profile: Windows XP; Windows Vista; Windows 7; Windows 8; Windows 10; MAC OS.When try to connect the wifi, it always shows “waiting for the network …”, and it disappears after you entering the security key. Please check the Service Pack of your laptop to see whether it’s SP1 、 SP2 or SP3 ( Click on Start, find my computer, right click on my computer and choose properties) SP1 can support WEP ony; SP2 can support WEP 、 WPA-PSK(WPA-personal); SP3 can support WEP 、 WPA-PSK （ WPA-personal ） 、 WPA2-PSK （ WPA2-personal ） Please make sure of the SP version of your laptop and set the corresponding security type. Once connected to the wifi, it shows “Validating identity” （ Windows cannot find a certificate to log you on the network ） Please try to cancel the authentication by click Here 4. Try to change your SSID and channel on the router’s configuration page. The Next Generation TCP/IP stack is a complete redesign of TCP/IP functionality for both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) that meets the connectivity and performance needs of today's varied networking environments and technologies.For a complete list of resources, see the Next Generation TCP/IP Stack Web page.This three-part expert lesson provides best practices for securing a WLAN in the enterprise.
