Probably better to post this sort of thing to mobile or hardware, but
I'll take a shot at it.

Is it possible that you have power management enabled? For a Orinoco
or Prism ][ based card, this will cause a significant delay in the
start of transmission as the transmitter is powered on. 200 ms. is a
bit long. For the wi driver, the default is 100 ms.
