Sorry, engage brain before opening mouth.

I don't know what you're trying to do but you're looking in the wrong 
place and I suspect you're confused about some stuff.  When you attach 
your wired nic to a bridge and and turn the bridge on the nic gets set 
in promiscuous mode.  This is likely why you can ping the other wireless 
station through the wired nic.  To ping the wireless station through 
your AP then AP must either fwd the packet directly or bridge it using 
some mechanism.  You cannot bridge a wireless interface unless it's 
operating as an ap.  Either way it's an issue at the AP.

You can diagnose all this with tcpdump.
