Fortunately, there are several things you can try to diagnose and resolve WiFi connection problems on your Samsung TV. Here are the most common reasons for Samsung TV WiFi issues and how to fix them:

Causes of WiFi Not Working on Samsung TV

There can be various factors causing WiFi connectivity problems on your Samsung TV. Here are some of the most common ones:

Samsung TV Disconnecting from WiFi: What to Do?

If your Samsung TV keeps dropping its WiFi connection, don’t worry. Here are some useful troubleshooting tips and fixes you can try:

Check the WiFi Router Connection & Placement

  • The first thing to check is whether your WiFi router is working fine and has strong enough wireless coverage in the room where your TV is located.
  • Ensure your router is centrally placed and away from objects that can obstruct WiFi signals.
  • Also, verify that other devices, like your smartphone or laptop, can connect to the same WiFi network without any drops.
  • Reboot your wireless router if connectivity seems unstable.

Analyze the WiFi Signal Strength

Signal Strength Samsung TV

  • Run an internet speed test on your TV to analyze the WiFi signal strength.
  • Go to Settings > General > Network > Network Status to check wireless signal levels.
  • A weak signal under -70dBm can cause connectivity drops.
  • If the signal strength is low, try moving your WiFi router closer to the TV or install a WiFi range extender.

Switch WiFi Channels

  • Interference from nearby wireless devices can severely impact WiFi connectivity.
  • Log in to your router admin console and switch to a different WiFi channel like 1, 6, or 11.
  • Also, if available, set the router to a 5GHz band instead of the more crowded 2.4GHz band. This can reduce interference.

Forget the Wireless Network

Reconnect Internet on Samsung TV

Deleting your existing WiFi network connection profile and reconnecting afresh often fixes connectivity issues.

  • Go to Network settings on your TV,
  • Select your troublesome WiFi network and choose ‘Forget’.
  • Now, search and reconnect to the network by entering the correct password again.

Update Your TV and Router Firmware

Samsung Tv Software Update

Keeping your Samsung TV and WiFi router firmware up-to-date will ensure you have the latest wireless protocols and connectivity fixes:

For your TV firmware

  • Go to Settings > Support > Software Update > Update Now on your TV. This will check for and install any available updates.

For your router firmware

  • Log into your router’s admin interface via a web browser. Check the router manufacturer’s website for exact steps.
  • Look for a Firmware or Software update section. Download and install any new firmware.
  • Consult your router manufacturer’s site and your router admin interface to find the current firmware version and release notes. This will reveal if new firmware resolves WiFi problems.

Both TV and router manufacturers periodically release firmware updates to improve connectivity. Keeping firmware updated should fix wireless bugs.

Adjust WiFi Settings on the TV

Check that the WiFi network settings configured on your Samsung TV are correct:

  • Verify the name of the wireless network matches your router’s SSID.
  • Ensure the security encryption setting is identical to your router (WPA2 is typical).
  • Confirm that the WiFi password entered is correct.
  • Set IP settings to DHCP instead of static.

Renew the IP Address of the TV

  • If your TV has connectivity but pages don’t load, renewing the IP address assigned to your TV may help.
  • Go to Settings > General > Network > Network Status > View Details of Selected Network and choose Renew IP Address.

Connect the TV to Ethernet

Try Ethernet Instead of WiFi

  • If your TV keeps disconnecting from WiFi, no matter what, did you try
  • Use an Ethernet cable to connect your Samsung TV directly to your router for a stronger, uninterrupted wired connection
  • This will provide the most reliable 4K/HD streaming and gaming connectivity.

Replace Faulty WiFi Antennas

If your Samsung TV uses internal WiFi antennas to connect and the above steps don’t help, the antennas may be defective. You can replace just the antennas in some models rather than the entire wireless module.

Here are the steps to replace WiFi antennas

  • Unplug the TV power and remove the TV from the wall mount if needed.
  • Open the rear TV cover and locate the WiFi antennas. They are small wires attached to the wireless module.
  • Detach and remove the existing antennas. Make a note of their original position.
  • Attach the new replacement antennas in the same positions. Make sure connections are secure.
  • Close the rear cover, then reinstall the TV if wall-mounted. Restore power – the new antennas should work!

When shopping for replacement antennas, look up the exact Samsung TV model to get the correct compatible parts. Follow installation directions closely. Getting the right antennas in the right positions is key.

Factory Reset Your TV

Factory Reset Samsung TV

If all else fails and your Samsung TV’s WiFi issues persist, perform a factory reset. This will erase all device settings and refresh the TV to its default state, which can resolve software glitches.

  • Open Settings, and then select General.
  • Select Reset, enter your PIN (0000 is the default), and then select Reset.
  • To complete the reset, select OK. Your TV will restart automatically.
  • If these steps don’t match your TV, navigate to Settings, select Support, and then select Self Diagnosis. The rest will be located on that menu. You can also check the user manual for exact instructions for your TV model.


A Samsung smart TV that loses internet connectivity can ruin your entertainment experience. Thankfully, problems like frequent WiFi disconnections can usually be fixed with some simple troubleshooting.

Follow the tips outlined in this article to determine what’s causing the WiFi drops and take appropriate measures to restore smooth and stable wireless connectivity on your Samsung television.
