Connect via Wi-Fi or Ethernet — Which One to Use

Most Samsung TVs connect to the internet in one of two ways: Wi-Fi or an Ethernet cable. Wi-Fi is wireless and works from anywhere in your home. Ethernet is a physical cable that plugs directly into your TV's back panel and offers a more stable connection if your router is nearby.

Wi-Fi is simpler if you do not want cables running across your room. Ethernet is better if your TV is close to your router, if you stream 4K video often, or if your Wi-Fi signal is weak where your TV sits. Most people use Wi-Fi and have no problems. Choose Ethernet only if you have a specific reason — like buffering during streaming.

Key Takeaways

  • Access the Network settings from your TV's main menu, then select Wi-Fi or Ethernet depending on your setup.
  • For Wi-Fi, your TV will scan for available networks; select yours and enter your password exactly as it appears, including capital letters and special characters.
  • If your TV does not find your network, move your router closer, restart both devices, or check that your router is broadcasting the network name.
  • Once connected, your TV will show a confirmation message and you can then open apps like Netflix, YouTube, or Samsung's app store.
  • If connection fails, restart your TV and router, check your password, and move closer to the router to rule out signal problems.

Connect Using Wi-Fi on Your Samsung TV

Start at your TV's home screen. Press the Menu button on your remote (or the button marked with three horizontal lines). Scroll down to Settings and press Enter. From Settings, find General, then select Network. You should see Open Network Settings — select that option.

Your TV will now show a list of Wi-Fi networks in range. Find your network name (also called the SSID) and select it. A keyboard will appear on your screen. Type your Wi-Fi password carefully — passwords are case-sensitive, so "MyPassword" is different from "mypassword". Include any numbers, symbols, or capital letters exactly as they appear. Once you have typed it, select Connect.

Your TV will attempt to connect. This usually takes 10 to 30 seconds. You will see a message saying "Connected" or "Connection successful" when it works. If you see an error message instead, check the troubleshooting section below.

Connect Using an Ethernet Cable

An Ethernet cable looks like a thick phone cord with a plastic clip on each end. One end plugs into your router; the other plugs into the Ethernet port on the back of your Samsung TV. The port is usually labeled "Ethernet" or shows a cable symbol. Push the cable in until you hear a click.

Once the cable is plugged in, go to your TV's Menu, then Settings, then General, then Network. Select Open Network Settings. Your TV should detect the wired connection automatically and show "Connected" within a few seconds. If it does not, unplug the cable, wait 10 seconds, and plug it back in.

Ethernet cables are inexpensive — a 25-foot cable costs between $5 and $15 at most electronics stores. If you need a longer cable, buy one rated for your distance; longer cables work fine as long as they are Ethernet cables (Cat5e or Cat6).

What to Do If Your TV Cannot Find Your Network

If your Wi-Fi network does not appear in the list, the problem is usually signal strength or a router setting. First, move your router closer to your TV — even 10 feet closer can make a difference. Restart your router by unplugging it for 30 seconds, then plugging it back in. While it restarts, restart your TV the same way.

Check that your router is actually broadcasting your network name. On a computer or phone connected to that router, look at the Wi-Fi networks available — if your network name does not appear there either, log into your router's settings (usually through a web browser or the router's app) and make sure the network name is set to broadcast. Most routers have this turned on by default, but some do not.

If your network appears but your TV will not connect, the password is usually the problem. Double-check that you are typing it correctly. Passwords are case-sensitive and spaces count. If you are not sure of your password, check the sticker on the back of your router or log into your router's settings to see or reset it.

Fix Connection Errors and Timeouts

If your TV shows "Connection failed" or "Cannot connect to network," start by restarting both devices. Unplug your TV for 30 seconds, then plug it back in. Do the same with your router. Once both have restarted, try connecting again.

If the error persists, move your TV closer to your router temporarily to test whether distance is the problem. If it connects when close, your Wi-Fi signal is weak at your TV's location — consider moving your router, using a Wi-Fi extender, or switching to Ethernet.

If you see "Incorrect password" even though you are sure the password is right, reset your router to its factory settings (this erases your Wi-Fi password and network name, so only do this if you are willing to set them up again). Most routers have a small reset button on the back that you hold for 10 seconds. After reset, set up your network again from scratch.

Test Your Connection and Start Using Apps

Once your TV shows "Connected," open an app to confirm the internet is working. Press the Home button on your remote and look for Netflix, YouTube, or another streaming app you have used before. Open it. If the app loads and plays video, your connection is working.

If an app loads but video buffers or stops, your connection may be slow. This is common on older routers or when many devices are using the same Wi-Fi network. Restart your router and TV, close other apps running on your TV, and try again. If buffering continues, consider using Ethernet or moving your router closer.

Frequently Asked Questions

Can I connect my Samsung TV to a guest Wi-Fi network?

Yes. Guest networks work the same way as regular networks — your TV will see the network name in the list and connect using the guest password. Some routers broadcast the guest network separately; if you do not see it, check your router's settings to make sure the guest network is turned on.

What if I forgot my Wi-Fi password?

Check the sticker on the back or bottom of your router — it usually shows the default password. If you changed it and cannot remember it, log into your router through a computer or phone using the router's IP address (usually printed on the router) or use the router's app. From there you can reset the password or view the current one.

Do I need to enter my password every time I turn on the TV?

No. Once your TV connects successfully, it saves the password and reconnects automatically when you turn it on. You only need to enter the password once, unless you change your Wi-Fi password or forget the network.

Can I use a 5GHz Wi-Fi network instead of 2.4GHz?

Yes, most Samsung TVs support both. 5GHz is faster but has shorter range. If your router broadcasts both, try 5GHz first — if your TV is far from the router or the signal is weak, switch to 2.4GHz. Your router's settings let you see which frequency each network uses.

Why does my TV keep disconnecting from Wi-Fi?

Frequent disconnections usually mean weak signal, interference from other devices, or an outdated router. Move your router closer, restart both devices, or check that no microwave or cordless phone is running near your router (they can interfere with Wi-Fi). If disconnections continue, try Ethernet instead.
