Start with the basics: power cycle and distance

The first step is almost always a power cycle. Unplug your Samsung TV from the wall outlet, wait 30 seconds, and plug it back in. While it restarts, also restart your router by unplugging it for 30 seconds. This clears temporary connection errors that block most TVs from finding your network.

Next, check your distance from the router. Samsung TVs with built-in WiFi work best within 20 to 30 feet of your router with a clear line of sight. If your TV is in a bedroom two rooms away or behind a metal filing cabinet, the signal may be too weak to connect. Move the router closer, move the TV closer, or remove obstacles between them and try again.

If your TV has an ethernet port on the back, plug in a wired connection instead. This bypasses WiFi problems entirely and is the fastest way to know whether the issue is your network or your TV.

Key Takeaways

  • Power cycle both your TV and router by unplugging each for 30 seconds, which fixes most connection failures.
  • Check that your TV is within 20 to 30 feet of your router with no major obstacles between them, since weak signal is the most common cause of connection loss.
  • Verify your WiFi password is correct by checking your router's label or settings, because a single wrong character will prevent connection.
  • Forget the network on your TV and reconnect from scratch if you changed your WiFi password recently, since the TV may still be trying to use the old one.
  • If your TV connects but then drops the connection, check for interference from microwaves, cordless phones, or other devices on the 2.4 GHz band.

Verify your WiFi password and network name

Open your TV's network settings and look at the WiFi network name (SSID) it is trying to connect to. Make sure it matches the name printed on your router or shown in your router's admin panel. If your router broadcasts two networks — one labeled with "5G" or "5GHz" and one without — your TV may be looking for the wrong one. Most Samsung TVs connect more reliably to the 2.4 GHz network, so try that first.

Check your WiFi password character by character. Look at your router's label on the back or bottom, or log into your router's settings page (usually 192.168.1.1 in your browser) to confirm the exact password. Passwords are case-sensitive, so "Samsung123" is different from "samsung123". Type it slowly and double-check before you submit.

If you changed your WiFi password recently, your TV is still trying to use the old one. Go to your TV's network settings, select the network name, and choose "Forget" or "Delete". Then search for the network again and enter the new password.

Check your router's WiFi band and channel settings

Samsung TVs sometimes struggle to connect when your router is set to broadcast only on the 5 GHz band. If your router has a setting to choose between "2.4 GHz only", "5 GHz only", or "Both", select "Both" or "2.4 GHz". Your TV will then have the option to use the more reliable 2.4 GHz connection.

If your router lets you choose a WiFi channel, try switching from the default. Channels 1, 6, and 11 on the 2.4 GHz band are the least likely to overlap with neighbors' networks. Log into your router's settings, find the WiFi channel option, and pick one of those three. Wait a few minutes for the change to take effect, then try connecting your TV again.

Some routers have a feature called "band steering" that automatically moves devices between 2.4 GHz and 5 GHz. Disable this feature if your TV keeps dropping the connection, because Samsung TVs do not always handle the switch smoothly.

Look for interference from other devices

Microwaves, cordless phones, baby monitors, and wireless speakers all use the 2.4 GHz band, the same frequency as most WiFi networks. If your TV connects but then loses the connection every time you use the microwave, or if it connects slowly when your cordless phone is in use, interference is the problem.

Move your router away from these devices, or move them away from your TV. If that is not possible, ask your router settings whether you can switch to the 5 GHz band instead — it has less interference but shorter range. Alternatively, if your TV has an ethernet port, use a wired connection to avoid WiFi interference altogether.

Update your TV's software and check for router compatibility

Samsung releases software updates that fix connection bugs. Go to your TV's settings menu, find "Support" or "About", and look for a "Software Update" option. If an update is available, install it and restart your TV. This often resolves connection problems that were not present in older software versions.

If your router is very old (more than 5 or 6 years), it may not support the WiFi standards your Samsung TV expects. Check your router's model number and look up its specifications online to see what WiFi standards it supports. If it only supports WiFi 4 (802.11n) or older, consider upgrading to a newer router that supports WiFi 5 or WiFi 6, which are more reliable with modern TVs.

Reset your TV's network settings

If none of the above steps work, reset your TV's network settings to factory defaults. Go to Settings, then Support, then Reset, and look for "Reset Network Settings" or "Network Reset". This erases all saved WiFi networks and passwords from your TV. After the reset, your TV will restart, and you can set up the connection from scratch as if it were new.

Before you reset, write down any other WiFi networks your TV was connected to, because you will have to re-enter their passwords. After the reset, search for your network, enter your password carefully, and wait for the connection to complete. This process usually takes 1 to 2 minutes.

When to check your internet service and contact Samsung

If your TV still will not connect after trying all the steps above, the problem may be with your internet service itself. Check whether other devices in your home — a phone, laptop, or tablet — can connect to the same WiFi network. If they cannot, contact your internet provider to check whether your service is working.

If other devices connect fine but your TV does not, the TV's WiFi hardware may be faulty. Contact Samsung support with your TV's model number (found in Settings > Support > About TV) and describe what you have already tried. They can walk you through additional troubleshooting or arrange a repair if the hardware is defective.

Frequently Asked Questions

Why does my Samsung TV connect to WiFi but then disconnect after a few minutes?

This usually means interference from another device on the 2.4 GHz band, or your router is dropping the connection because it does not recognize your TV. Try switching to the 5 GHz band if your TV supports it, moving your router closer to the TV, or using an ethernet cable instead. If the problem persists, update your TV's software and reset the network settings.

My Samsung TV says the password is wrong, but I know it is correct. What do I do?

Check that you are typing the password in the correct case — WiFi passwords are case-sensitive. If you recently changed your password, forget the network on your TV and reconnect with the new password. If the TV still rejects it, restart your router and try again, because sometimes the router takes a moment to register the new password across all devices.

Can I use a WiFi extender or mesh network with my Samsung TV?

Yes, but connect your TV to the main router if possible, not the extender. Extenders can cause connection drops on Samsung TVs. If you must use an extender, make sure it broadcasts the same network name as your main router, and place it in the same room as your TV for the strongest signal.

What if my Samsung TV does not have a WiFi option in the settings menu?

Older Samsung TV models may not have built-in WiFi. Check your TV's model number in Settings > Support > About TV, then search online to confirm whether it has WiFi capability. If it does not, you can add WiFi using an external device like a streaming stick, Roku, or Apple TV plugged into an HDMI port.

Does my Samsung TV need to be on the same WiFi band as my phone?

No. Your phone and TV can be on different bands — your phone on 5 GHz and your TV on 2.4 GHz — and they will both work fine. In fact, this is often the best setup because the 2.4 GHz band is more reliable for TVs, while 5 GHz is faster for phones and laptops.
