Samsung TV Not Connecting to Wifi? How To Fix

  • Samsung is a well-known multinational company from Korea. The company is famous for its quality electronic products such as TVs, phones, microwaves, and other products. Samsung’s Smart TVs are popular with many for their ease of connectivity and high-quality screens.
  • However, many users have reported having issues with the Samsung TV not connecting to Wifi.

What Prevents Samsung Smart TV from Connecting to the Wifi?

As mentioned, the Samsung TV has problems connecting to the Wifi, which could be due to several reasons.

Old and outdated firmware

Suppose your TV has old firmware that has not been updated to the latest firmware version. In that case, it might not work because it needs a firmware update for its settings to be configured appropriately according to regions. Check online if there is the latest update.


There have been numerous reports about the TV software being affected by a general bug. If you turned the TV off via the remote for more than 15 minutes, the network settings become corrupted. This means you have to reset them for the connection to work. You might also have downloaded a bug from the internet.

Mac Address Block

All smart devices connected to a Wifi router use a specific address to connect to the internet, also known as the Mac address. Sometimes, the Mac can be blocked from Wi fi connection, either by the ISP or the user. If this happens, the TV will not establish an internet connection until the ISP or user removes the block.

DNS Settings

The DNS establishes a server via which the TV will establish the connection. In some situations, the DNS settings on the TV may not be configured appropriately.

This results in conflicts between the TV and the router while attempting to connect to the internet. You have to manually change the settings for the TV to connect correctly to the internet.

Router or Modem issues

If your router or modem has an issue, your Samsung TV will not connect to your wireless network. You can replace the modem to solve the connectivity issues on your TV.

How to Fix Your Samsung Smart TV

With this basic knowledge of the potential problems, we shall look at the solutions. 

Restart or Reboot the TV

When your TV gets a bug, it becomes difficult to configure its settings. If the Samsung TV not connecting to Wi fi is an issue, you may need to restart the TV to get rid of the bug. There are two ways to restart a Samsung not connecting to Wi fi and fix Samsung TV. The first step is:

  • Ensure your TV is on.
  • On the remote, hold the power button
  • Long hold it until the Samsung log appears on your TV screen
  • The red LED light on the TV will start to blink fast
  • When the TV comes on, try to connect it to your Wi fi network

The second method to fix Samsung TV is:

  • Turn on your TV and keep it on for five minutes.
  • Turn it off, but do not use the remote. Unplug the cable from the power source
  • Please wait at least 30 minutes for it to continue resetting. 
  • After 30 minutes, please turn on your TV normally and try to connect it to the Wifi. If the TV doesn’t connect, try another solution.

Check Your Password

Using the wrong password is one of the most common reasons for your Samsung TV not connecting to Wifi. In such scenarios, the user might type in the wrong password by mistake. Ensure you type in the password correctly to prevent such an internet connection issue from occurring. 

The typing error happens because the on-screen Samsung Smart TV keyboard is not as easy to use as a phone or computer keyboard. If your TV can detect your wireless network but cannot establish a connection, try to re-enter your password correctly to fix Samsung TV.

  • On your remote, press the Home button
  • Go to Settings>General>Open Network Settings> Wireless
  • Select the Wireless network you want your Samsung Smart TV to connect to and carefully type in your password. You can see the password you are typing in by enabling the Show Password option.
  • If your password is too long or complicated, change it to a short and simple one to prevent a similar problem from occurring.

Reset the Network Settings on your Samsung Smart TV

If your TV is not establishing a connection to Wifi or won’t detect your wireless network, it may be an issue with the network settings configuration. To fix Samsung TV, reset the network on your Samsung Smart TV.

  • On the TV remote, press the Home button
  • Go to Settings>General>Network
  • Click on Reset Network and click Yes
  • Restart your TV and reconfigure the TV’s network settings 

Disconnect Any Devices Connected to Wi-Fi

Some Wifi routers come with a preset limit of devices they can connect to. If you are attempting to connect to a wireless mobile hotspot via a smartphone, go to the device mobile hotspot settings and check if there is a limit of devices. Try disconnecting all other devices, then connect the TV alone and see if the problem persists.

Try to Connect to Another Wireless Network

The Samsung TV not connecting to Wifi may also be one of two scenarios:

  • Your Samsung can find the available networks but cannot connect to them
  • Your Samsung TV cannot detect any wireless network

If you want to fix Samsung TV, try to connect the TV to a mobile hotspot on both issues. If the Smart TV does not connect to one mobile hotspot, try another smartphone or Wi fi router.

If your TV establishes a connection to a wireless network, either the router or hotspot, your Samsung Smart TV has no issue. If your router has too many connected devices, it might not handle all the devices, and you may experience connectivity issues. Reduce the connected devices to solve the issue.

Check if the other connected devices can connect with no issues. If all the devices connect with no problem, then your TV has an issue.

Manually set the DNS Server

The DNS (Domain Name System) settings may be the problem and conflict with your internet router, preventing a Wifi connection to the internet. Typically, devices like Smart TVs, smartphones, or computers resolve DNS through the IP to establish an internet connection. If your TV cannot do this, you can manually reset the DNS server.

  • On your remote, press Menu> General> Network Status
  • Click Start>IP Settings
  • Under Ip settings, select DNS mode and select “Enter manually.”
  • Press OK
  • Enter After typing the first 8, use the > button to navigate to the next field to enter the next 8 until you are done. Press the Done button on the number selection bar. Try to make the connection to the internet.

Check Your Network Signal Strength

If your TV keeps losing its internet connection, the solution might be:

  • Go to Settings> Network> Network Settings>Wireless
  • Check how many bars your Wifi network has. If it has one or two network bars or keeps changing, your internet connection may be unstable. 

In this unstable Wifi connection scenario, your Samsung Smart TV will establish a connection, but you cannot load or stream anything on the internet. This happens if the router is behind several walls. The solution for this issue is to move the device nearer your TV or buy a Wifi repeater to make the signal stronger.

Restart your Router

This solution should help your Smart TV connect to a Wifi connection if there is a problem with your router or hotspot.

  • Unplug the Wifi router from the main power source
  • Wait at least five to ten minutes and restart
  • Let the device load internet settings for about 5 minutes
  • Go to Settings>General>Network> Network Settings> Wireless
  • Select the preferred Wifi network you want your Smart Tv to connect to
  • Check if this solution has worked

Network Compatibility with Your Samsung Smart TV

Any Samsung Smart TV model launched before 2018 may only support 2.4 GHz networks. Your Wifi router might support a 5GHz network, and your older Samsung TV model will not detect this wireless network. In this case, you need to contact your Internet Service Provider to step down your Wifi network settings to 2.4 GHz.

Unblock Mac Address

Mac address failures or system complications might cause your Samsung TV Wifi connection problem. You can perform a factory reset on your Samsung TV as a possible solution.

  • Go to Settings>General
  • Press Reset
  • Enter the PIN to activate the system or factory reset. The default PIN for this is 0000

Unblock MAC Address

If the problem is a block on your Mac address, by ISP or router, you can unblock it.

  • To find the Mac Address of your Samsung TV, go to Support and About this TV.
  • Note the Mac Address and write it down
  • Give the address to your internet service provider and request for them to unblock 

Change Modem or Router

If all the above solutions do not work, and your Samsung TV is still not connecting to the internet, request your ISP to swap your Wifi router or internet modem for a newer version. When the internet modem or Wifi router is changed, restart your TV before you attempt to connect your Samsung TV.

Update TV Software

In finding a solution to the Wifi connection issue, you can update to the latest firmware on your Samsung TV. As the problem is the internet connection, you need to update the firmware and manually install it. Ensure the firmware is the latest version before you download it.

Edit Your Router Settings

Your router configuration settings could be an issue. You can:

  • Ensure your router firmware is up to date and check if the issue is resolved.
  • Disable PiHole, Nvidia Shield, etch to check if they were blocking your Wifi connection
  • If your router is dual-band (2.4 or 5 GHz), check if disabling one frequency or changing the frequency names will solve the Wifi connection issue.


If you try all these tips to fix Samsung TV and none works, you may have to involve a professional. Do not attempt to open up the TV, as this will void your warranty if still active. Contact the Samsung Support Center and arrange for a professional to look at your Samsung Smart TV. If your TV only has a connectivity issue, one of these solutions will work. 

If not, then you can take the next step. By going to the Samsung website or looking at customer reviews online, you can easily gauge what you are experiencing with your TV. Due diligence before taking the TV to a repair shop is advised. Have patience and go through each one of the steps until you are sure none of them works.
