Defines the number of times a packet is resent if the initial transmission
is unsuccessful.
Range: 1 to 128
Default: 16 (2.4-GHz client adapters) or 32 (5-GHz client adapters)
Note
Defines the threshold above which an RF data packet is split up or
fragmented. If one of those fragmented packets experiences
interference during transmission, only that specific packet would need

Throughput is generally lower for fragmented packets because the fixed
packet overhead consumes a higher portion of the RF bandwidth.
Range: 256 to 2312
Default: 2312
