What does Ethernet mean?
Ethernet is a family of wired local-network technologies. For a stationary television, a supported Ethernet connection can remove wireless airtime and reception from that local hop. It does not eliminate limitations elsewhere between the device and the media source.
Why it matters
Read the actual port specification: some televisions use a lower-rate Ethernet port than their Wi-Fi radio's advertised maximum. Stability can still make the wired link useful. Cable quality, connectors and router ports matter too. Use a sound supported cable and compare the same programme over a normal session. An Ethernet icon does not establish the whole internet route's speed.
A practical example
A wired comparison that removes repeated pauses points toward the previous wireless path, provided the player and source stayed unchanged. It does not automatically prove that every future source fault is local.
