This article will provide a set of proven solutions to address this issue, along with possible reasons why the WiFi feature on the TV might be malfunctioning.

What Prevents Samsung Televisions from Connecting to WiFi?

Our investigation has revealed that there is no single cause for the problem, which can arise due to various reasons. Some of the most prominent causes include:

  • Outdated Firmware: A television’s firmware that hasn’t been updated to the latest version might not function correctly. The TV needs the newest firmware to ensure all settings are appropriately configured based on the region.
  • General Bug: There have been reports of a common software bug in Samsung Smart TVs. If the TV is turned off using the remote for longer than 10 to 15 minutes, network settings may become corrupted and require resetting to establish a proper connection.
  • MAC Address Block: Each device connects to a WiFi router using a unique MAC address. Should this address be blocked—either by the user or the ISP—the TV will no longer connect to the WiFi router until the block is lifted.
  • DNS Settings: Incorrectly configured DNS settings on the TV can lead to conflicts with the router while attempting to connect to the internet. These settings may need to be manually adjusted by the user for the internet to function correctly.

Equipped with an understanding of why the problem occurs, we can now explore the solutions. It’s recommended to follow these solutions in the given order to prevent potential conflicts.

Solution 1: Restarting the TV

In some cases, the network settings may become corrupted if the TV is turned off with the remote for an extended period.

  1. Power on the TV as you usually would and let it run for 5 minutes.
  2. Instead of using the remote, unplug the power cable directly from the wall socket.
  3. Wait for at least 20 minutes before powering the TV back on.
  4. Enter the WiFi password if prompted, and verify if the issue has been resolved.

Solution 2: Restarting the Internet

The issue might lie with internet connectivity or incorrect DNS settings of the router, preventing the TV from accessing the internet.
