About this tag
The dfs channels tag on WindowsForum.com covers Wi-Fi disruptions caused by Dynamic Frequency Selection on 5 GHz networks. The tagged discussion explains how a router detecting radar on a DFS channel must abandon that channel, producing interruptions that resemble random Windows disconnects: a Teams call freezes, a stream stops, and the PC reconnects moments later without an obvious error. Disabling DFS channels is presented as a plausible router-side diagnostic step rather than a universal fix, with FCC rules requiring equipment to detect radar, stop transmitting, and vacate the affected channel. The focus is practical troubleshooting of unstable Wi-Fi and unexplained dropouts.
