For service providers and enterprise support staff alike, todays' networks depend heavily on Wi-Fi WLAN as the last hop to the end user and IoT devices.  Once interference and proper WLAN operations are verified and eliminated as possible causes for issues, the only remaining method to troubleshoot the WLAN is to sniff packets, analyze the network performance and understand what problems may be arising.

Wireshark can be very helpful in illustrating performance issues, and possible WLAN behavior issues.
