Sounds like you're using TKIP and the ap detects MIC errors in the 
frames you are sending.  When this happens it is required to enable 
countermeasures that include dropping traffic for a period of time. 
Check if your station negotiated WME; there have been problems with 
using h/w TKIP together with WME that require doing the MIC calculations 
in s/w.  The crypto support in current doesn't have all these changes.

If there's no WME negotiated then I'm not sure what to say; TKIP works 
fine in both h/w and s/w use in all my testing but I brought in a number 
of fixes (some WPA-related) shortly before the freeze.
