You have installed a new 802.11ac WLAN configured with 80 MHz channels. Users in one area are

complaining about poor performance. This area is currently served by a single AP. You take a spectrum

analysis capture in the poor performing areA. While examining the waterfall plot you notice the airtime

utilization is higher on the first 20 MHz of the 80 MHz channel when compared to the rest of the channel. What do you conclude?

When performing protocol analysis, you capture an 802.11ac data frame on channel 52, transmitted at MSC 8.

At what data rate was the PHY Preamble transmitted?

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?
