High Retransmissions
The number of retransmitted frames per second exceeds the threshold set in Expert Thresholds. Retransmissions occur when the transmitting station fails to receive an acknowledgment for a transmitted packet.
Possible reasons for this event:
Two or more stations are transmitting simultaneously, generating collisions.
The receiving station is out of range.
The receiving station is down.
Any one of these can cause both devices to back off and retransmit at random times. Too many retransmissions can indicate a system problem.
