What does Signal-to-noise ratio mean?
Signal-to-noise ratio compares the desired radio signal with the surrounding noise level. It adds context that signal strength alone cannot provide. A useful Wi-Fi connection depends on receiving the intended transmission clearly enough amid the actual radio environment.
Why it matters
Different devices expose different diagnostics, and a single number should not become a universal quality promise. Interference and channel use can change over time. Compare the usual viewing period and keep placement consistent. Router documentation or vendor support can help interpret the available measurement for the particular model rather than applying thresholds copied from unrelated equipment.
A practical example
Two rooms can show similar signal strength but behave differently because one has a noisier environment. That can help explain why moving a player or access point slightly changes reliability without changing the broadband package.
