Question
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?
Options
- AThe AP is misconfigured and needs to be reconfigured to 80MHz operation
- BRRM is enabled and has dynamically picked a 20 MHz channel
- CThe first 20 MHz is the AP's primary channel and higher airtime utilization on the primary channel
- DNon Wi-Fi interference is preventing the APs 80 MHz operation
