RAT runs fine over Wireless unless there's a lot of loss - do you see
loss of packets over the wireless? (check the reception quality
matrix). If you're seeing loss you could try enabling rendundancy in
menu->transmission. Typically a 802.11b or g or less are fine. If
you;re using multicast there may be issues due to the AP - though it
usually works ok on most APs unless there's alot of multicast.
