Did you configure the WinXP Home laptop to use shared key

This message is printed out when authentication failed and a station
entry was not added. The most probable cause for this is that the client
tried to repeatedly use open system authentication. You can verify this
by uncommenting a debug entry in driver/modules/hostap_ap.c. In the end
of handle_authen() function, change "#if 0" to "#if 1" and the driver
will print out the reason for this authentication failure.
