Why is my Wi-Fi connection not working with the Fire TV Stick?

Ensure your internet is functioning properly and try restarting your router and modem, which resolves most Wi-Fi issues. Avoid placing your wireless router or Fire TV Stick in a cabinet, as it may impact Wi-Fi signal strength. Use the 5 GHz band on your wireless router if available, and consider using the included HDMI extender to improve Wi-Fi signal.
