Actual exam question for CWNP's CWAP-405 exam
Question #: 24
Topic #: 1
You are troubleshooting a client that is experiencing slow WLAN performance. As part of the troubleshooting activity, you start a packet capture on your laptop close to the client device. While analyzing the packets, you suspect that you have not captured all packets transmitted by the client. By analyzing the trace file, how can you confirm if you have missing packets?

Suggested Answer: A Vote an answer

Each 802.11 data frame includes a sequence number in the MAC header that increments for successive frames within a traffic stream. If sequence numbers are not consecutive and there are gaps without corresponding retransmissions, this indicates that some frames were transmitted but not captured by the analyzer, confirming missing packets in the trace.
