A network technician is addressing user complaints of sporadic disconnections from the wireless network in a multi-floor office building. The issue is reported to occur mostly on the third floor, but no pattern is recognized regarding the time of day or specific client devices. What initial action should the technician take to best approach the problem replication process?
Reboot all wireless access points on the third floor and observe if the issue persists.
Change the router's wireless channel for the third floor to see if disconnections stop.
Use a WiFi analyzer tool to monitor for variations in signal strength and activity on the third floor.
Review the device logs on affected client devices for error patterns.
