Wireless Client Cannot Reconnect to a Wireless Access Point (828940)



The information in this article applies to:

  • Microsoft Windows XP Professional
  • Microsoft Windows XP Home Edition

SYMPTOMS

On a Microsoft Windows XP-based computer, you successfully make a wireless network connection to your network. However, you lose the connection and you cannot reconnect to the network unless you do one of the following:
  • Restart your computer.
  • Eject and then re-insert the network card.
  • Disable and then re-enable the network card.

CAUSE

This problem occurs because the wireless access point receives a connection request while the access point is trying to re-authenticate the wireless client for the same wireless network card. This later reconnection request is interpreted as a network attack on the access point. When this event occurs, the access point rejects the connection from the wireless client.
