About this tag
The windows wlan tag collects WindowsForum discussions about wireless networking on Windows PCs, from unexplained Wi-Fi disconnects to the router-side causes behind them. One recurring theme is 5 GHz DFS radar events, where a router must abandon a channel after detecting radar, producing an interruption that looks like a random Windows disconnect during a Teams call or stream. Coverage treats disabling DFS channels as a plausible router-side diagnostic step rather than a universal fix, and explains the FCC rules requiring radar detection and channel vacation. Expect practical troubleshooting for unstable Wi-Fi, plus context on how Windows reconnects and reports such events.
