This article describes why an outdated network router may not function correctly when you use it together with new networking features in Windows Vista. When you use an older router together with Windows Vista, you may experience any of the following problems:
- Slow network connection speeds or Internet connection speeds
- Gradual loss of network performance
- Lack of support for new features or for networking technologies
Windows Vista uses a new network stack and provides new networking features that may not be fully compatible with an outdated network router. For example, Windows Vista uses UPnP-certified standards much more than Microsoft Windows XP. An outdated or less robust network router may be unable to handle the increased UPnP traffic that is generated by Windows Vista. Therefore, network packets may be dropped. When this problem occurs, you may experience any of the following problems:
- Page errors occur when you surf the Internet.
- Network performance is reduced.
- The network router may stop functioning, and you must reset the router.
