Question

City hall’s VoWLAN SSID shows retry rates climbing above a 10% operational baseline during morning council prep, while associated RSSI still looks acceptable. How should the wireless expert interpret that metric?

Accepted Answer

Elevated retries indicate an RF or contention problem that needs remediation before chasing application settings — Retries are the WLAN’s early-warning light—like a check-engine lamp that flickers before the car stalls. When voice retries blow past a ~10% baseline, the RF/contention story is already unhealthy. Fix the medium first; don’t start by blaming the softphone settings.

Answer

Retries above 10% are normal for voice and can be ignored if MOS scores are unmeasured

Answer

High retries prove the RADIUS server is overloaded and authentication must be redesigned first

Answer

Retry growth means the controller license count is exhausted and new APs cannot join
