Wifi on the TV, what to do if we have problems with signal reception. Life hack How to improve the Wi-Fi signal of a home router in five minutes Why does it badly catch Wi-Fi on the TV

What progress has reached - now, in order to watch videos on YouTube or search for the necessary information on the Internet, you do not need to run for a laptop or grab a smartphone. Anything you want can be done through the TV. The only prerequisite is the Smart TV function. Electronic stores offer a fairly wide selection of TVs from different manufacturers with the Smart TV function, which, by the way, are not cheap.

But the end justifies the means. Convenience, comfort and pleasure from viewing such TVs with excellent image quality, and even with the ability to access the Internet, is hardly worth discussing. Undoubtedly, Samsung Smart TVs have become one of the leaders in this segment of goods.

What should you know before setting up your Smart TV?

Your dream has come true and you have taken out that very Samsung Smart TV from the box. We determined its place, put it there and now it's time to start setting up. What do you need to know and be able to in order to use the Smart TV function smoothly?

Let's start in order and analyze the order of TV settings via Wi-Fi. Of course, there is an option to connect the TV directly through a wire, but this is not a very convenient option.

Additional cable, wire knots - all these are hassles and inconveniences that are unlikely to please. There will be opponents and connections via Wi-Fi, because many believe that such a connection is not capable of providing an uninterrupted connection to the Internet. But this is not true. The interruption of communication and the lack of its stability is exclusively a problem of the router. If the processor of the router is strong enough and the Internet provider provides fast Internet, then there will be no problems. Otherwise, either change your router or internet service provider.

Before proceeding with the Smart TV settings, you need to clarify a few points, namely:

Does your Samsung Smart TV come with a built-in Wi-Fi adapter? If yes - this is great, if not - then you need to purchase it. If you buy an adapter, be sure to pay attention to the fact that it is individual for each Smart TV model.
Is the router configured and working properly? But, if the router is not new and your smartphone or tablet already has an Internet connection, then you can skip this item, because all the necessary settings have already been made. Otherwise, setting up a router for Internet access will require specialist intervention.

What do I need to do to set up Smart TV over Wi-Fi?

The Samsung Smart TV will probably automatically prompt you to go to settings the first time you turn it on. But this point can be omitted - when buying a TV, you have already turned it on in the store. If the purchase was carried out via the Internet, then such an offer from the device should be expected. Samsung Smart TV will also start searching for wireless connections on its own, if you are not using a direct network connection via cable, for example. Smart TV step-by-step setup looks like this:

Turn on the TV, press the button on the TV remote control Settings«.

In the TV menu, go to the tab Network and select the item Network connection.

Next, the possibility of a wired or wireless connection is displayed. Push the button "Configure connection".

Choose from the list the desired wireless network. Attention! If there is a need to set your own parameters when connecting, then you must select the item Manual configuration... For example, this will be needed to connect to a network with a hidden SSID, when using a static IP address, or to connect using WPS technology and other possible options.

Next, you need to specify password to connect the TV to a Wi-Fi hotspot.

Push Ok.

On the next window, you will see the connection status. The network is connected, the signal is stable. Click the button.

If you are prompted to enter IP and DNS, then select "receive automatically". You can use the functions of the technology! If Smart TV mode is activated, then at the top you will see an icon showing an Internet connection.

After you have successfully connected to the network via Wi-Fi, you will need to go to the “Menu” again and select the “Smart Hub” function in the “Support” tab. She is able to open access to many information resources on the Internet. With its help you can watch videos on YouTube or visit other Internet pages.

What to do if Smart TV connection fails?

It often happens that everything seems to be done correctly and the sequence is followed, and the Samsung Smart TV stubbornly refuses to connect to the network via Wi-Fi.

In this case, you need to understand the reason for this behavior and eliminate it. Among the most common are incorrect router settings. Check connectivity on other devices in your home - phones, laptops, tablets. If they also do not see the network, then of course move towards fixing the problem in the router. If the Samsung Smart TV refuses to connect, then your next action will be to correct the error in setting up Smart TV.

This technology has both smartphones, laptops and desktop PCs, as well as refrigerators, TVs and other household appliances. Many users use routers to connect their devices to the Internet, they can have a LAN port to connect using a cable, or a Wi-Fi adapter to distribute the Internet to other devices that also have Wi-Fi technology. Unfortunately, the coverage area of the wireless signal is not very large, and if there are obstacles in the way, it is generally very small. Of course, there are many standards on which the signal strength depends, and the number of antennas is also an important parameter.

If you are using Wi-Fi technology, but do not know what you can do to strengthen the WiFi signal of your adapter, then this article is for you. Here I will try to explain the hardware and software ways to improve the signal.

But before we start, I would like to note one important point.

Pay attention to the location of the router. It would be nice if he was closer to the middle of the room and the whole house, so that the signal spreads evenly and you feel comfortable using the wireless network. Signal degradation can be caused by many factors. At home, these are walls, and if it is also concrete, then it will be much worse to transmit radio waves. Any thing - from a picture, a drawing or a mirror can deteriorate signal reception to some extent. Therefore, I want you to try to position your router in such a way that the signal is available in all areas of the house. If possible, remove things that might interfere.

How to improve WiFi signal reception using programs?

Many users out of inexperience leave the default settings of the router, unless they change the network name and password. This is not entirely correct and now I will explain why.

Channel frequencies coincide with other Wi-Fi networks

If you live in an apartment building, then there is almost a 100% chance that there is a Wi-Fi network that broadcasts over the same channel as you. This phenomenon often interrupts signal reception. In the settings of the router, you need to change the channel to a free one or to the one with the least other wireless networks.

You can see who is sitting on which channel using the program inSSIDer... Download it from here and install it on a PC with a mongrel adapter.

The found wireless networks will be indicated in the program window, and in the column "Channel" the channels they occupy are exposed. In the Russian Federation, only thirteen channels are usually used, in other countries either more or less.

We figured out the channels, then we will start changing the settings of our router. Usually the following addresses are used for this, which must be entered into the address bar of the browser: http://192.168.0.1 or http://192.168.1.1... Next, you will be asked to enter your username and password, if you have not changed anything, then by default it is admin (and username and password).

You need to find the functions related to the wireless network Wi-Fi, it can be written Wireless. There will definitely be a section Channels(Channel), among which you can select a number from 1 to 13.

Change the channel to free and save. After this action, you will suffer much less interference and the signal will be more stable.

Low router transmitter signal

By default, some routers may have a low transmitter power. But it can be changed. Find the parameter in the same router settings Transmission power(Transmit Power), and set the value to 100%. Or you need to select a value High(High).

Of course, this function is not available on all models. Sometimes special firmware for such models helps, if any.

802.11n is faster

In Wi-Fi, there are many standards by which a wireless network can operate. The fast is, of course, 802.11n, which still gives a wider range if multiple antennas are used. You also need to take into account the support of this standard by other devices, because if you switch to it, some devices, due to underexposure of the range, will not detect your network.

In the parameters of the router, look for "Mode of operation" or "Wireless network mode", or "Wireless mode" and switch to 802.11n. Restart the router for the changes to take effect.

Using the 5 GHz band

The use of the 802.11n standard makes it possible to use two types of bands in expensive models - 2.4 GHz (used by all devices) and 5 GHz(Not used by everyone). The 2.4 GHz band is very busy, it is used by many devices around us, and these are not only wireless adapters, but even a microwave oven can create problems for us. The 5 GHz frequency range is now almost free, so it is advisable to transfer all devices to it.

Improving Signal in Windows

At this point, more attention is focused on laptops. The fact is that when you set "Energy saving" in the power consumption settings, it can affect the strength of the Wi-Fi signal. Therefore, it is better to expose "Balanced" mode, or "High performance"... Then you will receive the signal from a greater distance.

Who does not know, the power settings are in the following place: right-click on the battery icon on the taskbar and select "Power supply" and set the required control scheme.

Signal strength limiting and can it be removed?

I would like to note that all routers have a hard power limit of 100 mW. Of course, there are adapters in Chinese stores that are capable of taking distances up to several kilometers, but you will not find this in ordinary electronics stores. Is it possible to increase the signal strength by software? Answer: partially you can.

Unfortunately, there is some difficulty - you need to use a Linux distribution, for example, Kali Linux, or an analogue - Backtrack 5r3, whose support has ceased.

The fact is that in most countries the power of a wireless transmitter is limited to 100 mW, but for Bolivia and some other countries there is no such limitation, so in the terminal you need to enter a number of such commands:

In this example wlan0 Is the wireless adapter you are using and 100 - exposed power in mW (milliwatts).

How to strengthen WiFi signal by hardware method?

All means are good, which means that together with software methods we will be able to achieve a stable and high transmitter signal. Even if the programmatic methods did not work, the following methods may help.

Signal improvement with antenna upgrades

I have seen many ways to amplify the Wi-Fi signal on the Internet. For example, people make a directional antenna that works in all directions and for this they use foil or a can of Pepsi or beer. Of course, the use of such methods is doubtful, but for whom how.

More powerful antennas, which can be purchased at the store, are more effective. You need to make sure your antenna is 2-3 dBi, then they can be replaced with 8 dBi antennas.

Using a repeater to amplify the reception signal

These devices are also called repeaters, and they can greatly increase the coverage area. The repeater connects to your wireless network and increases its range.

Buying a more powerful Wi-Fi adapter

You can do this: if you have a laptop that has insufficient signal reception on the wireless adapter, replace it with a more powerful one. This also applies to desktop computers. It is best to get an adapter that is connected via USB and has an antenna, which, perhaps, can be replaced with a more powerful one.

If you have other ways to increase the signal of the wi-fi adapter, write about it in the comments, everyone will be interested.

Of course there is a solution called Smart TV.

Connecting to the Internet on modern devices is the easiest procedure. If we want to watch a movie or receive a service via Wifi, we need a router.

Probably all of them have, I emphasize, a router with Wifi.

Note that not every modern TV has

But if such a module is not installed initially, the issue is solved simply. It is advisable to purchase and install Wifi via USB!

Of course, first find out which USB modules the manufacturer recommends. So you save yourself the headache with the selection of compatible devices.

Check your router settings before connecting directly. The main thing is that the DHCP service is connected in the LAN settings.

The connection itself. Connecting a TV to the Internet is no more difficult than connecting a computer. Of course, each device has its own unique features, but the idea is the same everywhere.

Setting up the connection.

*Turn on the TV and press the Settings button on the remote. Maybe it will be called something else. But the meaning is the same. You should get into the settings menu. Next, I will explain using the example of an LG TV. As already noted, I have exactly LG.

*In settings there is a "Network" tab. In it you need to select the "Network Connection" item.

*On the screen a list of available wireless networks will appear. We choose the right one.

*Enter your password, if, of course, there is a need for this, and such a need will be if the router already has a password.

If the password was entered without errors and there are no problems with the network, a message will appear on the screen saying that the wireless network is working properly. Confirm by clicking ok.

Why clicking?

I'm kidding, my TV has two remotes. So in the working (small) there is a bear function, like on a computer, An arrow is visible on the TV screen, which you point to the desired one and click with the remote control wheel.

Distracted, but not a problem, CONTINUE.

Sometimes you may be asked to enter IP or DNS. Select "Automatic". A network map can be created in the same way. As you can see, there is nothing difficult to start watching movies on TV via wifi.

If your router and TV support WPS technology, then you are a lucky person!

Just press the WPS button on the router and in the TV settings select the appropriate item - "WPS". The TV will immediately connect to the network and will not require additional data to be entered.

But if you connected and the signal is bad, even with interference, then it makes sense to dig further.

The wifi channel in the router settings.

Due to the fact that interference appears on the channel, many problems arise in the operation of the Internet via Wi-Fi. We are talking about router channels, yes, there are such channels!

Frequent breaks, low connection speed, unstable work, etc. All this may be due to the fact that other networks start working on the channel on which your network operates and it turns out that the channel is very busy.

Because of this, there can be problems with Aunt Shura, and of course if you watch a movie from a computer on TV.

So there is only one conclusion, the signal of your router and the neighbor's (house, entrance, apartment) intersect, which means that they work on the same channel. Because of this, unpleasant problems arise: low speed of the Internet, disconnected connection and many, many other problems.

As a result, something should be done with this byaka.

We think it is logical, at the factory settings, some one channel is selected, to which all Vasya's neighbors are connected, after all, they also do not know about the channels in the router. Therefore, it is best to set it to AUTO at the beginning.

This means that the device itself will search for a less loaded element and connect with its help.

But this does not always give success or, I shall say, the best choice.

To select a static value, analyze your network with the inSSIDer utility. It will show the load of all elements. So you can choose the most free one for further connection to it.

Change settings.

The change occurs in different ways on different devices, so below I will show how to do this on popular models.
TP-Link

First you need to go to the control panel of the device. After connecting to it, enter the address in the address bar,

Login and password are the same everywhere: admin.

Now take a close look at the panel on the left. Find the same menu item highlighted in the photo below. In the "Channel" item, select the required number.

Save your changes.

As you can see, this is very easy to do. Just reboot the router so that it rebuilds to a new value.

D-Link

Entering the settings is exactly the same as for the above-described router.
With this router, the situation is much simpler. Open the tab named "Wi-Fi" and find the appropriate item.

Just enter your number and save.

By the way, in some models you can see the load of each element, so there is no need for different programs.

Asus

The input is the same, so go to the settings and solve the problem with the knowledge gained. Finally, if you have one.
Here, changing the Wi-Fi channel in the router settings is similar to the D-Link device. Only the tab is called “Wireless Network”.

After saving the settings, you don't even need to reboot. He will do it himself.

Zyxel

The login information remains the same as for other routers. Go to the "Wi-Fi network" and change the data in the corresponding item. Save all changes.

Tenda

It may not be the most popular router, but to someone it is nicer than all the rest. The login is the same, but you don't have to specify the password. Open the highlighted tab. And in the "Channel" point, enter your value.
Save your changes.

* Do not put 12 or 13 values. Some devices may simply stop seeing your Wi-Fi, so don't risk it. Choose any unoccupied number.

* When making the necessary changes to the settings of your router, be sure to check if it correctly identified your country. This is necessary for the correct display of the items available to you.

* After scanning your network, you find that all the elements are busy, then you need a 5 GHz router.
Buying a new device with a different frequency will solve your problems. The speed is much better there due to the low workload, so if you can get a new device, choose with that frequency.

* HOWEVER, I think that everything should work well in auto mode. If there are any problems, then you can reboot the router and it will choose a different channel.

And if you forcibly install, say, a second channel, which is still chosen by several people, then nothing good will come of it.

So we act as mentioned above!

If nothing good came out of this, or you have a desire, then you can use the inSSIDer program, or WiFiInfoView to find a free channel.

Good luck Friends!

There are 10 main ways to restore WiFi to work on modern TVs. Most of them are related to correcting wireless settings. Required settings on Samsung, LG, Panasonic and Sony devices can be changed at home without contacting a service center.
Let's take a look at all the main ways to fix configuration errors in turn:

1. Reboot TV and router

The first steps to take if WiFi is not working on the TV is to reboot the Smart TV and the router. The malfunction can be programmatic and can be easily corrected by reinitializing the device drivers. To restart the TV, turn it off and on again. Some experts also recommend removing the plug from the electrical outlet and then plugging it back in. This advice makes sense for those TVs that remain connected to the local network even after the screen is turned off.

During the reboot of the router, you must wait 10-20 seconds between turning off and turning on. During this time, the previous Internet session will be closed on the provider's side. Therefore, the connection will be made anew, with the settings reset to zero. When Smart TV and router turn on again, try to connect WiFi.

2. Manual specification of connection data

Using the built-in Smart TV menu, navigate to the WiFi connection options. Select the manual mode for specifying settings if the DHCP server is disabled on the router, and the connection with automatic parameter detection does not work. In the "IP address" line, enter any IP from the local range. Valid start and end addresses are available for clarification in the admin panel of the router.

In the "Subnet mask" field, you must specify which part of the IP range will be used to address clients on the local network. The common value for this parameter is 255.255.255.0. In the "Gateway" line, enter the IP address of the router, which is used to enter the settings.

Advice! The subnet mask and gateway can also be checked through any computer connected to your router. To do this, select Command Prompt from the context menu of the Start button. In the window that opens, enter the command: "ipconfig / all" and press "Enter".

3. Troubleshooting DNS server errors

This method is especially relevant for Samsung TVs. Accessing the Internet and multimedia content through the Smart Hub becomes difficult when Samsung's servers are overloaded. When specifying your DNS server addresses, the connection to Internet resources will be made directly, without using the manufacturer's infrastructure.

DNS server addresses are specified in the provider's support. You can also use the free public DNS. This service is provided by Google, Yandex, OpenDNS. For example, to use Google's address servers, it is enough to enter the IP of the main server: 8.8.8.8 and the additional one: 8.8.4.4. If there is no text field for entering an alternate server, enter only the first address in the DNS settings.

4. Using a different WiFi connection method

If you established the connection by manually entering the password from the wireless network, try connecting via WPS. WiFi Protected Setup technology allows you to activate the fast connection mode in the TV settings. After that, a similar mode must be activated on the router. This is done through the control panel or a dedicated button on the back of the case.

To access the router's web interface, turn the device over and find the login sticker. It is usually located on the bottom side and indicates the standard IP address, username and password. Enter the IP in any browser and enter the account information available on the sticker. Then go to the "WPS" section and activate this function. The fast connection will be available within 1-2 minutes.

In the case when the WPS protocol was used initially, but at the moment the connection cannot be established, enter the information manually. When connecting to a hidden network, you will need to specify not only the access key, but also the WiFi name (SSID). TVs with earlier firmware versions do not always support Hidden Network Search. Therefore, before updating the software, it is recommended to remove the hiding of the network name in the router settings.

5. Reset TV settings

A quick way, which in some cases helps to solve problems with WiFi on Smart TVs, is to restore factory settings. Before executing it, it is advisable to rewrite the values of the main parameters that are not related to the network. After the reset, you can get them back based on the information recorded. Menu path to restore factory settings on popular TV models:

Lg: "Settings -> Advanced -> General -> Reset to factory settings."
Samsung: "Support -> Self-diagnosis -> Reset".
Panasonic: "Settings -> System menu -> Initial settings".

Note! Factory reset will return more than the default network settings. Picture, sound, power saving and other Smart TV settings will not be saved.

6. Changing the location of the router

Problems with the wireless network on the TV may be due to poor signal reception from the router. If possible, move the router closer to the Smart TV and install it so that there is less interference in the path of radio waves. The main obstacles to signal transmission are walls, furniture and working appliances.

Installing the hotspot on an elevated level will help ensure better WiFi connectivity. For example, you can put the router on top of a cabinet or hang it over a door. If you cannot move the router closer to the TV, connect a stronger antenna to it. The higher the antenna gain, the better the Smart TV network will work.

7. Finding problems with a WiFi router

If you are having difficulty connecting to a wireless network, it might be due to incorrect router settings. To change them, go to the control panel. Click the DHCP tab and make sure the DHCP server is enabled and working properly. Disabling it will not automatically assign a local IP address to the TV and other network devices. Normal routing and Internet access will not be possible.

Check the "Security" tab in the router settings. If client MAC filtering is enabled, disable it. On routers ASUS, TP-Link, D-Link, Huawei and some other manufacturers, the MAC address of any device can be whitelisted. In the future, connections of devices from this list will not be blocked, so normal WiFi operation on the TV will be restored.

The MAC address of Smart TV is specified in the settings. The exact path differs depending on the brand, on most TVs of popular manufacturers, the necessary information is in the menu:

Samsung: "Support -> Contact Samsung -> Down arrow -> MAC of the wireless interface".
Lg: "Settings -> Support -> Product Information".
Philips: "Installation -> Manually configure the network -> View network settings -> Start".

Important! After adding MAC address of Smart TV to the "white list" or changing other parameters of the router, restart it. To do this, use the menu item "System" or "System Tools". You can also use the power button on the case or temporarily unplug the device from the outlet.

8. Updating the TV's firmware

Smart TV built-in software needs to be updated in a timely manner. Errors can accumulate as you work, making it difficult to connect to the Internet via WiFi. Depending on the TV model, the update can be done in several ways:

Through a wireless network;
Using the cable Internet;
Via an external USB storage device (USB flash drive or hard drive).

If WiFi on Smart TV does not work, use the second or third option to download the new software version. Detailed instructions for updating the software are usually posted on the website of the company that released the TV. Possible names for the desired section: Help, Support, or Help Center.

While the utility is running, it is important not to disconnect or de-energize the device. Any interruption may affect the further functionality of the Smart TV. Do not use third-party firmware to avoid loss of warranty service.

9. Replacing the WiFi adapter with an external one

This method will not correct any problems with the internal radio. But if it is because of them that errors occur when connecting, use an external device. The form factor of such a WiFi adapter resembles a regular USB flash drive. Like most other devices, it works when connected to a TV via USB.

On sale there is another type of adapters for receiving WiFi. They have an external multi-directional antenna that provides better signal reception from the router. It is recommended to connect such modules via a USB extension cable, placing them at some distance from the TV. Thanks to this connection, interference from a working Smart TV will be minimized, and the data exchange speed will increase.

Important advice! Before purchasing an external adapter for connecting to a wireless network, check the list of supported devices in the instructions. This information can also be found on the manufacturer's website or in technical support.
