A DHCP reservation gives a device a consistent local address through the router. It can help with network administration and local discovery, but it does not raise stream quality or fix a congested internet route.
Use a real administrative need
A reservation is useful when a documented local integration expects a stable address. Ordinary outbound playback rarely needs one. Start with the problem you are solving rather than assigning static addresses to every television as a performance ritual.
Reserve at the router
Where supported, create the reservation in the DHCP interface using the correct device identity. Follow the vendor's instructions and avoid overlapping manual settings on the player. Private or rotating Wi-Fi addresses may affect how the router identifies a device.
Check after reconnection
Reconnect the device and verify that it receives the intended configuration. Keep the original automatic setup available. If playback behaves exactly as before, do not describe the reservation as a speed improvement merely because the address is now predictable.
