I am unclear still on what happens.  I believe you are saying:

ping 192.168.0.1

from the station to the ap fails.  If so what does 80211stats show on 
the ap when this happens (do releveant error stats go up)?  If you do

80211debug +input

on the ap do you get any log msgs about discarded frames?

You also seem to say the sta resolves the ip w/ arp.  Is the same true 
for the ap (i.e. that it resolves the ip address of the sta)?  I'm 
assuming you are NOT running firewall rules do not have crypto setup and 
have not fiddled with parameters like apbridge (you didn't provide 
ifconfig output for each side).

I rarely test direct communication between sta+ap; usually I bridge to a 
wired net and communicate with stations on the wired net (it's always 
what I'm doing when I report netperf numbers).  Does bridged 
communication to a sta on another network work?
