I have enabled tracing in XP but it gives almost no useful information. 
Its all gobbledygook to me but I will attach it for some better eyes to 
look over it.
  What I have done is try the linux WPA_Supplicant under XP and it 
behaves the same.
  Ive worked out its somewhere in the ndis drivers. I get this in 
wpa_supplicants output.

ndis: media disconnect event
msndis_status_media_disconnect

There is no other useful information in the logs. I get the same output 
from a different working AP but without the disconnect message.

Trying to get logs from the ndis driver I see the same.

General Status : NDIS_STATUS_MEDIA_DISCONNECT (0x4001000C)

What makes this happen ? What does the NDIS driver look for to see if 
the media link status is up or down ?

Could it be my ralink rt73 hardware on hostapd? Next step is to try a b43.

If I keep pinging the interface from the client all is good and the link 
stays up. As soon as the interface is quiet for a few secconds it starts 
doing its disconnect and reauth thing, over and over.
  Searching google seems some users have the same problem with the 
ralink chipset but nothing involving hostapd.

Below is the windows XP EAPOL trace and WZCTrace. I only took a portion 
of it as it was huge.

Ive marked it in the middle where the disconnect happens.
Let me know if I need more logs.
