Ethernet is worth considering when Wi‑Fi is weak or erratic in that room and you can run a cable conveniently. Neither connection guarantees faster streaming or prevents buffering: performance also depends on your internet service, network congestion, TV hardware, and the route to the streaming service.
When Wi‑Fi is the better choice
Choose Wi‑Fi if the TV has a reliable signal and you would rather avoid routing a cable across the room. If streaming works consistently at the quality you want, switching to Ethernet may not make a noticeable difference.

When Wi‑Fi is unreliable, try improving the signal before changing connections. Netflix recommends moving the router and TV closer together, placing the router in an open, elevated location, and moving it away from other wireless devices and appliances. Netflix’s connection troubleshooting guide lists these steps for poor wireless performance.

When Ethernet is worth using
Ethernet connects the TV to the router with a cable, bypassing the wireless link between those devices. That can help if Wi‑Fi is weak or inconsistent in the TV’s room. It will not fix an internet-service outage, congestion elsewhere in the network, or every cause of buffering.

Before planning a cable run, check that your TV has an Ethernet port and that you can connect it to the router. Samsung’s TV connection guide describes wired Ethernet and wireless connection options; check your specific TV’s manual for its ports and setup steps. Ethernet requires a suitable cable reaching both devices, while Wi‑Fi does not.
How much speed does streaming need?
Use the streaming service’s own guidance rather than treating one speed figure as universal. Netflix recommends the following stable connection speeds for its listed video qualities:

These are Netflix recommendations, not guarantees or requirements that apply to every streaming platform. Netflix says that “Many factors can affect streaming video quality.” Its internet connection speed help page also explains how to check speed through the Netflix app on a TV or TV-connected device. A test reflects conditions at that moment; it cannot guarantee the connection will stay the same.

Pick the symptom - the matching free tool is one click away.
How to choose for your setup
- Wi‑Fi is stable at the TV: Keep using it unless you have a specific problem to solve.
- Wi‑Fi is weak or erratic in that room: Improve router placement or consider Ethernet if a cable route is practical.
- You are unsure whether speed is sufficient: Run the streaming service’s connection test on the TV and compare its result with that service’s recommendation for your viewing quality.
- You need to know which connection is faster on your model: Check the TV’s specifications. The available guidance does not establish that every TV’s Ethernet port is faster or slower than its Wi‑Fi hardware.
What to do if the TV buffers
- Run the streaming app’s network-speed check on the TV or connected device, if available, and compare the result with that service’s guidance.
- Restart the TV and home network as appropriate, then try the stream again.
- If the TV uses Wi‑Fi, improve the router’s position and reduce obstacles or nearby sources of wireless interference. If the signal remains poor and a cable is feasible, try Ethernet.
- If the problem continues, contact your internet service provider. Netflix recommends explaining whether the issue affects one device or several and whether the TV connects by Wi‑Fi or cable; those details can help narrow down where the problem occurs.
Buffering can arise from more than the TV-to-router connection. Netflix notes that congestion along the route to its service and the number of devices using the home connection can affect streaming quality. Its troubleshooting guidance recommends contacting the ISP if its suggested steps do not resolve the issue.
