Reason=4 is in fact "Inactivity timer expired and station was 
disassociated". According to my router log:
"Tuesday April 01, 2008 09:08:54 Disassociated: 00-19-D2-4F-22-4D 
because idle 300 seconds"

Indeed, the default behaviour goes for a reassocation but my hw/sw 
combination (intel3945/dlink/wep) fails with a status=17 (AP unable to 
handle new status). After 3 tries, it dies with an AP association 
timeout. From there is no recovery till I set the interface down and up.

That's why I solved it (perhaps not in the best way) ignoring the 
disassociation. Now it works.
