Stop unnecessary downloads and streams
Close other applications using bandwidth to get a clearer reading of available speed.

Measure the connection where your streaming device is used and consider stability, Wi-Fi quality, network congestion and simultaneous usage—not only headline speed.
Close other applications using bandwidth to get a clearer reading of available speed.

Run the test where the streaming device is normally used, especially when connected through Wi-Fi.
Choose a well-known testing service to measure download speed and connection performance.
Network performance can vary during busy periods, so compare results across the day.

Check whether measured download speeds align with the approximate range for the preferred quality.
Test close to the router and at the device location to understand the effect of signal quality.

A wired connection can provide more consistent performance than Wi-Fi.
Place the router in a central, open location and avoid hiding it behind furniture.
Pause large downloads or other streams to free bandwidth for playback.
A restart may clear a temporary fault and refresh the connection.
Install available updates for the streaming device and compatible application.
Comparing devices helps determine whether a problem is device-specific.
