Description: This counter shall increment when an ACK is not received when expected.
What is dot11ACKFailureCount?
This counter increments each time an expected acknowledgment (ACK) for a transmitted frame is not received. An admin watches this counter as an indicator of wireless link quality, since a high ACK failure rate typically precedes retransmissions and contributes to the overall failed-transmission count. A steadily rising ACK failure count alongside growing dot11FailedCount readings points to a genuinely degraded RF link rather than a transient issue.
