Command
$ netsh wlan show wlanreport

02What it does

This forgotten command correlates the WLAN-AutoConfig event log into a timeline: every connection, disconnection with reason code, radio state change and signal-quality graph over roughly three days. It is the fastest way to answer 'why does my Wi-Fi drop every few hours' without installing anything. Combine with netsh wlan show interfaces for the live snapshot and netsh wlan show profiles for saved networks.
