Root-cause analysis

Diagnosed cause

Severe airtime contention from co-channel interference

RCA confidence79%

Above the 70% threshold — a fix can be pre-formed.

Reasoning

Channel utilization is saturated with an elevated retry rate, the classic co-channel interference signature. An RF channel rebalance should relieve it.

Generated by heuristic

Evidence trail

channel_utilizationChannel utilization: 84%

Channel airtime is saturated.

retry_rateWireless retry rate: 27%

High retry rate confirms contention rather than client-side issues.

Channel utilization84%

Wireless retry rate27%

Proposed fix

Reassign the AP channel to reduce contention

Move the access point off the congested channel via the controller to lower airtime utilization and improve client throughput.
