Thanks to Internet access, a modern TV with the Smart TV function serves not only for watching TV shows, but also expands other multimedia capabilities: social services, instant messaging, visiting websites, 3D games, listening to music, watching streaming video. The most common way to connect equipment to the Internet is a wireless connection using the built-in wifi module. Manufacturers have included this interface in new models. However, after some time, users note that the TV does not connect to the Internet using Wi-Fi.
Malfunctions can be varied: the device does not see the router or sees it, but cannot connect. In this review, we will highlight the main causes of this problem and ways to solve them.
How to properly connect to the Internet via a wireless connection
To understand the reasons for problems accessing the Internet, let's look at how to connect using a wifi interface. Perhaps this is where the solution to the problem lies. The following actions are performed.
- Turn on the router - the connection should be active.
- We go to the menu, the button of which is on the remote control.
- Select the “Network” option. Go to the “Network Settings” tab.
- The system will prompt you to select a connection method. Select “Wireless connection”.
- From the list of found wireless signals, select the desired name and click “Next”.
- Enter a unique code.
- After establishing the connection, click “Ok”.
From the step-by-step algorithm it is clear that connecting via the wireless interface is simple, and the user should not have any questions. If they do arise, read more about connecting a TV with Wi-Fi to the Internet. If the connection still disappears, we will consider possible problems and their elimination.

Smart TVs are modern, sleek and stylish devices that harness the power of the Internet to give viewers an endless supply of movies, TV series and other content available with just a few clicks. And you can understand the level of disappointment that engulfs viewers when, after turning on, the device cannot find a wireless network. Simple advice from experienced owners of the popular TV format will help you quickly restore lost connections in the Internet world.
Rebooting the equipment
If the TV does not connect to the Internet via Wi-Fi, then the first thing to do is restart the TV and router. Sometimes the crash is caused by driver or software errors, and restarting allows them to return to functionality without drastic measures.
To restart the TV, just use the power button on the remote control to turn it off and on. If the device has the function of maintaining an Internet connection even after being disconnected, then a reboot should be done by unplugging the plug from the socket.
The router reboots in the same way - by turning it on and off. But at the same time you need a break of 15-20 seconds. During this time, the previous session will end, that is, the connection will be made again with updated settings.
After turning your router and smart TV back on, try resynchronizing them.
Android TV does not connect to WiFi - reasons and solution
The situation when, when turning on an Android device, the user sees a message that there is no Internet connection, occurs quite often. That is why many already know the reasons and solutions. So most often this problem can be associated with work on the provider’s side. Solutions if your Internet provider has no problems:
- Reboot the router.
- Reboot the router.
- Checking all existing connections.
- Checking all wires and cables for connection to the outlet and structural integrity.
You also need to disconnect and reconnect your Internet connection.
Setting up the Internet manually
The connection error may be caused by the fact that the DHCP server, which is responsible for automatically detecting parameters, is disabled in the router. In this case, you need to go into the settings on the TV, find the “network” item and select “manual setup”. To set the IP address value, you must select any of the local ranges for this router. You can find out this range in the router settings in your browser.
The next field is “Subnet Mask” - here you specify the value for addressing the local network. Most often it is "255.255.255.0". "Gateway" is the IP address of the router. It is the same one that is needed to launch settings through a browser - it can be found in the instructions.
Advice! To find the necessary configuration data, you can also use any PC connected to this network. Having launched the “Command Line” application, enter “ipconfig / all” and look at the result.
Checking the router operating range (2.4 and 5 GHz) and working channel
There are two ranges in which current routers operate, these are 2.4 Hz and 5 Hz; most of all, companies give preference to five hertz, since the speed of operation increases significantly. However, not all TVs are capable of operating in the 5 hertz range. To do this, you need to enable both broadcast bands in the router settings.
One more important point should also be highlighted: some TVs for Russia and Europe see five hertz on certain four channels, these are channels 36, 40, 44 and 48. 2.4 hertz implies operation in the range from channel 1 to channel 13 for Russia and the CIS countries. In the wireless mode section, you can change the channel yourself.
It is worth saying that if your TV is not made for the CIS countries and Russia, and this also applies to the router, then they may not see some part of the channels. To find out, try changing channels one by one in the router settings.
Making an alternative connection to Wi-Fi
The most common way to connect to Wi-Fi is to enter the password manually. If this method does not help, then you can use the WPS function, provided that the router has it . To connect to the Internet using it, you need to activate a fast connection on the TV (WPS mode), and then do the same in the router. To do this, there may be a special button on the case, or you will need to go into its settings. To do this, the browser indicates the IP address from the sticker on the bottom panel of the device (you can find it in the instructions). The username and password for logging in are also written here. Next, go to the WPS section and activate the connection.
Important! The connection has a limited validity period; if you do not have time, you will have to activate it again.
If synchronization was initially performed via WPS, then try entering the password manually. If the TV does not see the network, then its visibility is probably hidden in the router - this can be corrected in the settings.
Useful tips
In addition to the recommendations already listed, it is worth considering the following factors:
- whether the password for the access point is entered correctly;
- whether the router is working, how it is configured (even if the indicator is green, rebooting will not harm);
- Does the TV even have a radio module? If not, or it is faulty, and there is no way to take the equipment to a service center, you can connect to the Internet wired, using a LAN cable.
There are many reasons why the TV stopped receiving WiFi. Some of the problems can be solved on their own, but sometimes you cannot do without visiting a service center. In any case, it is better to check the equipment step by step, including network equipment, for possible errors or incorrectly entered settings.
Strengthening the signal
Sometimes a connection problem is caused by the TV not being seen by the router, or the signal being too weak. In this case, it is worth placing the devices close to each other - ideally, in the same room. You should also make sure that the problem is not caused by interference. They can be created by working household appliances - refrigerator, microwave oven and others.
Advice! If you cannot change the position of the router, then you can strengthen its signal by installing a more powerful antenna or a repeater.
If the above recommendations did not help, then the radio module is probably broken.
Determining the malfunction of the built-in wifi module
To diagnose the possible cause of a malfunction in the Wi-Fi wireless modular element, you need to examine the TV to determine its performance. However, first of all, make sure that the device supports the wifi interface. If you don't have it, you need to buy an external adapter that is compatible with the user's TV model. It looks like a small drive or flash drive. Otherwise, you can check the correct operation of the wireless module as follows (let's take a Samsung TV as an example).
- First, determine whether the TV will be able to see other devices via the wifi interface. A telephone connected to wireless technology is suitable for this purpose. This method will allow the user to determine whether the built-in module in this Samsung TV is working or not.
- Go to the main menu by selecting the “Support” option, then “Contact Samsung”. Scrolling down the pages, look at the numbers in the MAC address line. If the values are in the form of zeros, dashes or monotonous parameters, then the wifi module does not function.
Troubleshooting DNS server errors
The Samsung TV does not see the router, a common problem on this model. When Samsung servers are overloaded, it becomes difficult to use the Internet and TV functions. If you specify your DNS address, the connection with the Internet will begin to interact directly, that is, the manufacturer’s data will not be involved.
Your provider's support will help you clarify your DNS servers.
As an alternative, public servers are available. Such servers are provided by Google.
To use them, you need to enter the IP of the main server: 8.8.8.8 and the additional one: 8.8.4.4. If your TV does not have a field in which an alternative server is entered, then enter only the main one in the DNS settings.
How to update TV firmware
In order for Smart TV applications to function correctly and the TV to work stably and at high speed, it is necessary to update the device software. There are two ways to update the firmware: directly via the Internet or using a USB drive. Let's look at how to install the latest firmware on an Lg TV from a flash drive. To do this, follow these steps:
- go to the lg company website;
- enter the TV model;
- select the “support” tab;
- go to “by”;
- select the new version from the list of firmware;
- click on the link and download the archive to your computer;
- create a folder called “lg_dtv” and place the downloaded file there;
- connect the drive to the TV;
- the system will offer to download the updated version;
- Click "Run".
Note! When the firmware is updated, you cannot unplug the equipment from the outlet. To avoid unexpected power outages, use an uninterruptible power supply.
In this review, we studied in detail how to establish a connection to a router via a wireless interface. Users are given answers to why the TV does not connect to the Internet via wifi and basic ways to troubleshoot problems are offered.
Router location
Any obstacle can greatly weaken the signal from the router. Therefore, if the router is located very far from the TV, the signal may reach very low levels. Often, if the router is low-power or outdated, the signal is completely lost. Therefore, the TV stops finding Wi-Fi, even if the Internet is working. In the best case, the connection will be successful, but the Wi-Fi signal will not be strong enough to watch even low-quality video. There will be a constant loading icon on the screen with periodic resumption of viewing for a few seconds.
It is recommended to install the router as close to the equipment as possible. This is especially important if there are many Wi-Fi consuming devices in the apartment. Then you need to place it near a device that requires more Internet resources. And television is just that. Modern television receivers can play video in 4K resolution, which requires a high-speed, stable Internet.
It happens that it is not possible to install a router close to the TV. For example, the cable that was installed when connecting the Internet to the apartment is not long enough. Then you need to try to organize the placement of equipment and the router so that there is direct visibility with a uniform distance.
You can always boost your signal using a powerful router. There are models in the region of 2-3 thousand rubles, equipped with several antennas. More expensive routers are worth buying only for large rooms with many pieces of equipment, for example, offices.
