Ethernet: strengths and limits
A wired connection is usually less affected by walls, neighbouring networks, and radio interference. It can be a good test when playback freezes or varies by room. However, the result still depends on the router, internet service, cables, and provider stream. Some TVs also have Ethernet ports with lower maximum link speeds than modern Wi-Fi, though that may still be enough for the stream.
Wi-Fi: strengths and limits
Wi-Fi avoids running a cable and can work well when the TV has a strong, stable signal. Performance depends on distance, walls, interference, band selection, and the number of active devices. A strong signal indicator does not always guarantee low congestion or packet loss.
Which should you choose?
If the router is nearby, try Ethernet first when diagnosing instability. If a cable is impractical, place the router in an open, central position and test the TV’s actual location. Compare the same stream at the same time and avoid changing other variables during the test.
FAQ
Is Ethernet always faster? Not in every real-world setup, but it often provides more predictable local connectivity.
Can Wi-Fi handle 4K? It can when the wireless connection consistently supports the stream’s actual bitrate.
QA: Avoid absolute claims; compare reliability and convenience, not just theoretical speed.
