Ethernet removes wireless airtime competition from the player's local connection. Wi-Fi remains practical where cabling is inconvenient. Compare real playback and port capability before assuming either connection will be faster for your particular television.
Read the port specification
Some televisions have Ethernet ports slower than their newer Wi-Fi radios. A stable wired link can still be ample for the stream, but it should not be described as automatically faster. Check the device's network specification rather than the appearance of the socket.
Try the cable route
Use a sound cable and a known working router port. Route it without tight bends, door pressure or trip hazards. An intermittent connector can create a new fault that resembles the wireless problem you were trying to remove.
Judge stability over a session
Let a familiar programme play through the time when interruptions usually occur. Compare consistency, startup time and remote responsiveness. Leave other settings alone so the result reflects the connection change rather than a simultaneous quality reduction.
