Start with the basics: restart your TV and router

Most Samsung TV WiFi problems clear up with a restart. Power off your TV completely—not standby mode, but fully off—and unplug it from the wall for 30 seconds. While it's unplugged, unplug your router too. Plug the router back in first and wait for all its lights to stabilize (usually 2 to 3 minutes), then plug in your TV and turn it on.

This clears temporary connection glitches that build up over time. If your TV connects after this step, you're done. If not, move to the next section.

Key Takeaways

  • Restart your TV and router completely by unplugging both for 30 seconds, plugging the router back first, then the TV.
  • Check that your TV is in range of your router and that your WiFi password is entered exactly as it appears, including capital letters and special characters.
  • Forget the network on your TV and reconnect from scratch, because stored passwords sometimes corrupt and prevent reconnection.
  • Move your router closer to your TV or remove obstacles like metal objects and microwaves that block the signal.
  • If your router uses a 5 GHz band only, your TV may not support it—check your router settings and enable the 2.4 GHz band instead.

Check your WiFi password and network name

Open your TV's network settings by going to Settings > General > Network > Open Network Settings. Select your WiFi network from the list. When you enter your password, type it exactly as it is—WiFi passwords are case-sensitive, so "MyPassword" is different from "mypassword". Check for capital letters, numbers, and special characters. A single wrong character will block the connection.

If you're not sure what your password is, log into your router's admin page (usually printed on the router itself) or check your internet bill or account with your provider. Write down the exact password and enter it again on your TV.

Forget the network and reconnect

Sometimes the password your TV has stored becomes corrupted, even if you entered it correctly the first time. Go to Settings > General > Network > Network Status, then select your WiFi network and choose "Forget". This removes the stored connection completely.

Now go back to Open Network Settings, find your network in the list again, and enter your password fresh. This forces your TV to create a new connection file instead of using the old one that may have gone bad. Wait 10 to 15 seconds after entering the password—the TV needs time to authenticate.

Check your router's WiFi bands and channels

Older Samsung TVs support only the 2.4 GHz WiFi band, not 5 GHz. If your router is set to 5 GHz only, your TV cannot see or connect to it. Log into your router's settings (usually through a web browser or the router's app) and check which bands are active.

If your router has both bands available, make sure the 2.4 GHz band is turned on. Some routers call this "dual-band" mode. You can also check your TV's manual or Samsung's support site for your specific model number to confirm which bands it supports. If you're unsure how to access your router settings, contact your internet provider—they can walk you through it or make the change remotely.

Move your router closer and remove obstacles

WiFi signal weakens with distance and through obstacles. If your router is in a back bedroom and your TV is in the living room on the opposite side of the house, the signal may be too weak to connect reliably. Move the router closer to the TV temporarily to test whether distance is the problem.

Also check for metal objects, microwaves, and cordless phones near either the router or TV—these interfere with the 2.4 GHz band that most Samsung TVs use. Move the router away from these devices or move it to a higher shelf or more central location in your home. If moving the router solves the problem but you can't leave it there permanently, you may need a WiFi extender or mesh system to reach that room reliably.

Update your TV's software

Samsung releases software updates that fix WiFi connection bugs. Go to Settings > Support > Software Update and select "Update Now". Your TV will check for available updates and install them if found. This process can take 10 to 20 minutes, and your TV may restart several times. Do not unplug it during the update.

After the update completes, try connecting to WiFi again. If your TV cannot connect to WiFi to read the update, you can update it using a USB drive—check Samsung's support site for your model number to find the update file and instructions.

Check for hardware problems or contact Samsung support

If you've worked through all the steps above and your TV still won't connect, the WiFi module inside your TV may be faulty. This is a hardware problem that requires professional repair. Before you contact Samsung, have ready your TV's model number (usually on the back or in Settings > Support > About This TV) and a list of the steps you've already tried.

Samsung support can be reached through their website or by phone. If your TV is still under warranty, repair may be covered. If it's out of warranty, ask about the cost of repair versus replacement—sometimes a WiFi extender or a streaming device like a Roku or Fire Stick is a cheaper option than repairing the TV's built-in WiFi.

Frequently Asked Questions

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

This usually means your TV is too far from the router or the signal is weak. Try moving the router closer, or check whether other devices in your home are also dropping connection—if they are, the problem is your internet connection, not your TV. Restart your modem and router, and contact your provider if the problem continues.

My TV says "incorrect password" but I know the password is right. What do I do?

Forget the network on your TV and reconnect from scratch. If that doesn't work, reset your WiFi password in your router settings and enter the new password on your TV. Make sure you're typing it exactly as it appears, including capitals and special characters.

Can I use a USB WiFi adapter if my TV's built-in WiFi doesn't work?

Most Samsung TVs do not support external USB WiFi adapters. Your best option is a streaming device like a Roku, Fire Stick, or Apple TV, which plugs into an HDMI port and has its own WiFi. You can also use an ethernet cable if your router is close enough to your TV.

Does a WiFi extender work with Samsung TVs?

Yes. A WiFi extender creates a stronger signal in rooms far from your router, and Samsung TVs connect to it the same way they connect to your main router. Place the extender halfway between your router and TV for best results.

What if my TV connects to WiFi but the internet is very slow?

Slow internet on your TV usually means weak signal, not a TV problem. Move the router closer, remove obstacles, or use a WiFi extender. If other devices are also slow, restart your modem and router, and contact your internet provider if the problem persists.
