How close the two radios in each AP are to eachother? Are you using
external antennas or have you done anything to limit the interference
the other radio is going to give? At least try using channels that are
further apart (e.g., 1 and 11).

IEEE 802.11 uses acknowledgement of the frames, so in fact, cards are
still both transmitting and receiving frames. I don't think this is the
major issue. However, the receiver will have hard time trying to avoid
problems when the radio next to it is sending..
