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:
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.
