A city NOC captures while troubleshooting voice-SSID dropouts but leaves the adapter scanning channels. The failure never appears in the trace. What capture-method lesson applies?
Select an answer to reveal the explanation.
Short Explanation
If the radio is channel-hopping like a tourist, it'll miss the exact moment the voice call dies on the real channel. Lock the capture to the BSS channel and width. NetFlow won't show you 802.11 retries and roams.
Full Explanation
Protocol analysis of a voice failure requires frames from the channel (and channel width) where the BSS operates at the time of the symptom. Scanning adapters spend limited dwell time per channel and can miss short exchanges. NetFlow and unrelated fixed-channel choices do not substitute for an on-channel 802.11 capture.
