What does Dynamic Frequency Selection mean?
Dynamic Frequency Selection, or DFS, is behaviour used on certain Wi-Fi channels to meet spectrum-sharing requirements, including radar detection. Equipment may need to move channels when required. Available channels and rules depend on the region and device.
Why it matters
A resulting radio transition can interrupt a client briefly, but not every pause is a DFS event. Compare router event information with the actual failure time before assigning that cause. Use only supported regional settings and do not defeat regulatory protections. If repeated events affect viewing, consult the manufacturer's guidance for an appropriate alternative channel plan.
