You associated with the ap then fell off either because the ap dropped 
you or your station initiated it.  The easiest way to see which is to 
enabling debugging; I prefer to use 80211debug from tools/tools/ath; e.g.

80211debug state+assoc

or probably

ifconfig ath0 debug

will give you enough info.  The output of 80211stats should also tell 
you what happened.

I've been testing ath w/ static key wep today and seen no problems. 
Please get some more info.
