Fragment Threshold To fragment MSDU or MMPDU into small sizes of
frames for increasing the reliability of frame (The
maximum value of 4096 means no fragmentation is
needed) transmission. The performance will be
decreased as well, thus a noisy environment is
recommended.
RTS Threshold This value should remain at its default setting of
4096. Should you encounter inconsistent data
flow, only minor modifications of this value are
recommended.
