7500 isn't very many packets.

Try ping -f.  (f for flood, need to be root)

It takes me 13 seconds to get to 7500 packets.

If that doesn't find a problem, try longer packets.

In case you don't have a man page handy...
  -c xxx (c for count, stops after xxx packets)
  -s xxx (s for size, sends packets of xxx bytes)

-f puts an "interesting" load on things.  You might try XO to XO rather than 
going through the AP and/or loading the router.  (but the lights on the AP 
and/or router might be helpful)  Or XO to PC rather than router...
