UnpollerHighVAPErrorRate

A UniFi access point VAP is experiencing more than 10 errors per second (combined receive and transmit) for over 10 minutes.

Impact

Wireless errors indicate physical-layer or driver-level issues that degrade client connectivity, throughput, and reliability.

Diagnosis

• Check for RF interference sources near the affected AP.
• Review channel utilization and noise floor levels.
• Verify antenna connections and physical hardware condition.
• Check if errors correlate with specific firmware versions.
• Look for CRC errors, fragmentation, or crypto errors in the metrics.

Mitigation

• Change wireless channel to avoid interference.
• Reduce transmit power if signal reflections are causing issues.
• Update firmware to address known driver bugs.
• Replace hardware if physical defect is suspected.
