What is supposed to happen is that after 2 minutes of inactivity, a station
is dis-associated.  Some changes made to the host ap code incorrectly
changed
the time to 24 seconds (I submitted some fixes for that).  Still, I haven't
seen the behavior you describe with Windows XP.  Perhaps it's driver
related.

My windows XP machine keeps itself associated by sending occasional
do-nothing
LLC frames.  Maybe if the inactivity time-out value were larger (like 5
minutes), the LLC frames will come often enough to keep it from being
timed out. (?)  My freebsd client doesn't send LLC frames but it doesn't
care
if it gets dis-associated: it just reassociates without flapping the
interface.

Try the following change to wi_hostap.h:

120,121c122
< #define WIHAP_INTERVAL                        5
< #define WIHAP_DFLT_INACTIVITY_TIME    (120/WIHAP_INTERVAL) /* 2 minutes
*/
---
> #define WIHAP_DFLT_INACTIVITY_TIME    120     /* 2 minutes */


If that doesn't work, maybe I need to rethink how this disassociation
stuff works.
