The phone does not see the TV via wi-fi

Still have questions? Write a comment! Good luck!

Earlier, I already wrote about how to connect a TV to a computer in different ways, but the instructions were not about wireless Wi-Fi, but about HDMI, VGA and other types of wired connection to the output of a video card, as well as setting up DLNA (this will be and in this article).

This time I will describe in detail the various ways to connect a TV to a computer and a laptop via Wi-Fi, while several areas of application of a wireless TV connection will be considered. for use as a monitor or for playing movies, music and other content from a computer’s hard drive. See also: How to transfer image from Android phone or tablet to TV via Wi-Fi.

Almost all of the described methods, with the exception of the last one, require the TV to support Wi-Fi connection (that is, it must be equipped with a Wi-Fi adapter). However, most modern TVs Smart TVs can do this. The instructions are written for Windows 7, 8.1 and Windows 10.

Playing movies from a computer on a TV via Wi-Fi (DLNA)

For this, the most common method of wirelessly connecting a TV, in addition to the presence of a Wi-Fi module, it is also required that the TV itself be connected to the same router (i.e. to the same network) as the computer or laptop on which video and other content (for TVs with Wi-Fi Direct support, you can do without a router, just connect to the network created by the TV). I hope this is already the case, and no separate instructions are needed. the connection is made from the corresponding menu of your TV in the same way as connecting to Wi-Fi of any other device. See separate instructions: How to set up DLNA in Windows 10.

The next item is to set up a DLNA server on your computer or, more clearly, to share folders on it. Usually, it is enough for this to be set to “Home” (Private) in the parameters of the current network. By default, the folders “Videos”, “Music”, “Pictures” and “Documents” are publicly available (you can share a particular folder by right-clicking on it, selecting “Properties” and the “Access” tab).

One of the quickest ways to enable sharing is to open Windows Explorer, select Network and if you see the message “Network discovery and file sharing are disabled,” click on it and follow the instructions.

If such a message does not follow, and instead computers on the network and media servers are displayed, then most likely you have everything set up (this is quite likely). If it did not work, then here is a detailed instruction on how to set up a DLNA server in Windows 7 and 8.

After DLNA is enabled, open the menu item on your TV to view the contents of the connected devices. On Sony Bravia, you can go to the Home button, and then select the section. Movies, Music or Pictures and watch the corresponding content from your computer (Sony also has a Homestream program that simplifies everything I have written). On LG TVs. the SmartShare item, there you will also have to see the contents of the shared folders, even if you do not have SmartShare installed on your computer. For TV of other brands, approximately similar actions are required (and also have their own programs).

Additionally, with an active DLNA connection, by right-clicking on the video file in the explorer (we do this on a computer), you can select the “Play on TV_name” menu item. When you select this item, the wireless video stream from the computer to the TV will start.

Note: Even though the TV supports MKV movies, these files do not work for “Play To” in Windows 7 and 8, and they do not appear in the TV menu. A solution that works in most cases is to simply rename these files to AVI on a computer.

We connect a regular TV via Wi-Fi without a wireless adapter

If you don’t have a Smart TV, but a regular TV, but equipped with an HDMI input, then you can still connect it wirelessly to your computer. The only detail is that you need an additional small device for this purpose.

  • Google Chromecast, allowing you to easily cast content from your devices to your TV.
  • Any Android Mini PC (USB-like device that connects to the HDMI port of the TV and allows you to work in a full Android system on TV).
  • Coming soon (presumably early 2015). Intel Compute Stick. a mini-computer with Windows connected to the HDMI port.

I described the most interesting options in my opinion (which, moreover, make your TV even more Smart than many of the Smart TVs produced). There are others: for example, some TVs support connecting a Wi-Fi adapter to a USB port, and there are also separate Miracast set-top boxes.

I will not describe the work with each of these devices in more detail within the framework of this article, but if you suddenly have questions, I will answer in the comments.

TV as a wireless monitor (Miracast, WiDi)

If the previous section was about how to play any files from a computer on a TV and have access to them, now we will talk about how to broadcast any image from a computer or laptop monitor to a TV via Wi-Fi, that is, use its like a wireless monitor. Separately on this topic Windows 10. How to enable Miracast in Windows 10 for wireless broadcast to TV.

The two main technologies for this are Miracast and Intel WiDi, with the latter reportedly becoming fully compatible with the former. Note that such a connection does not require a router, since it is installed directly (By Wi-Fi Direct technology).

  • If you have a laptop or PC with a 3rd generation Intel processor, Intel Wireless Adapter and Intel HD Graphics, then it must support Intel WiDi in both Windows 7 and Windows 8.1. You may need to install Intel Wireless Display from the official website
  • If your computer or laptop was preinstalled with Windows 8.1 and equipped with a Wi-Fi adapter, then they must support Miracast. If you installed Windows 8.1 yourself, you may or may not be able to support it. No support for previous OS versions.

And finally, support for this technology is also required from the TV. Until recently, it was required to purchase a Miracast adapter, but now more and more TV models have built-in support for Miracast or receive it during the firmware update process.

The connection itself looks like this:

  • The TV must have support for Miracast or WiDi connection enabled in the settings (it is usually enabled by default, sometimes there is no such setting at all, in this case, the Wi-Fi module is enough). On Samsung TVs, the feature is called Screen Mirroring and is located in the network settings.
  • For WiDi, launch the Intel Wireless Display program and find the wireless monitor. When connected, you may be prompted for a security code that will be displayed on the TV.
  • To use Miracast, open the Charms bar (on the right in Windows 8.1), select Devices, then Projector (Transfer to Screen). Click on the “Add a wireless display” item (if the item is not displayed, Miracast is not supported by the computer. Updating the Wi-Fi adapter drivers may help.). details on the Microsoft website:

I note that I could not connect my TV via WiDi from a laptop that exactly supports the technology. There were no problems with Miracast.

DLNA technology

The optimal technology for such manipulations with media content is DLNA.

Windows supports it right from the factory, so you don’t have to install anything. Smart TVs of all generations and manufacturers usually start with it without any problems too. LG, Samsung and others should work right away. The topic of this article is general, it is better to try to find detailed instructions for each model in advance through the search on our website.

If something didn’t work out for you. ask your question in the comments to this article.

To use the technology, both the computer and the TV must be on the same local network. be connected to the same router by wire or by air. Usually, all the difficulties with connecting people arise at this stage, tk. one of the devices receives incorrect network settings, and as a result, they do not see each other. Ideally everything works right away.

But DLNA technology has a limitation. through it, it is excellent to transfer video from a computer to a TV. Transferring the desktop will not work, another technology is better suited here. Miracast (WiDi) or cable.

Miracast or Intel WiDi technology

These 2 technologies of the Wi-Fi Direct family are just right for us to broadcast the screen to the TV. Usually supported by both the operating system and modern TVs. If DLNA technology (described below) only allows you to transfer files to the network (perhaps this is what is relevant for you), then with these you can do exactly what is written in the title of the article. duplicate the screen.

  • Intel WiDi (Wireless Display) —You have a 3rd generation Intel processor or higher and have an integrated Intel graphics card. This is usually enough.
  • Miracast. any Wi-Fi adapter and operating system not lower than Windows 10.

Televisions now usually support these technologies (the very old one, but everything works). Although older models were previously offered to buy special Miracast adapters.


Usually everything is played right away. But sometimes this window can come out:

Click on “Enable streaming on media” and it should work. For greater persuasiveness, here you should make sure of the broadcast permission for your TV. There should be a check mark “Allowed”:

Once enabled, for further transmission attempts, this window should not appear. Any file will be transferred immediately.

Possible problems

The main fix: reboot everything. Step by step:

  • Turn off the computer.
  • Turn off the TV.
  • Turn off the router.
  • We wait 1 minute.
  • Turn on the router.
  • Turn on the computer.
  • Turn on the TV.

Most of the network problems will go away immediately. Other problems:

  • Doesn’t see the TV. the main thing here is to check that everything is on the same network, on the same router, and everything is connected. The other will usually save a reboot. Well, do not forget. the TV must support DLNA or be just Smart TV (old “boxes” will not fit for sure).
  • The format is not supported or The file is unavailable for reading and writing. check all codecs, is this file played by itself on the computer? In extreme cases, a glitch is possible on the TV, but usually the trouble is on the computer, the main thing is that everything is reproduced and so.
  • The movie slows down and stutters. usually the problem is in the speed of your network and router. The larger the film, the more difficult it will be to deliver it “on time”. So we either improve the bandwidth of our network, or compress the transmitted video file, or connect via cable.

Addition. I remembered another common reason why the TV is not visible on the network. network detection is turned off. The easiest way to fix this is:

  • Go to Explorer
  • Selecting the Network
  • We click on the yellow plate on top with a warning. Everything should work:

If this warning is not present, and other computers and devices of your home are quietly displayed in the window, everything is fine, the problem is something else.


And now a frankly simple instruction, which may surprise. usually, when we work, we simply do not notice this function in the most conspicuous place. Let’s try to play the video on a TV. We select it, right-click, select “Transfer to device”, where our TV should be (Windows 10):

On Windows 7, this item is called “Play To”.

A window for control will immediately open, and our

In fact, this is a regular player. Here you can add other files to the queue, control rewind and do the same thing that can be done when viewing on a computer.

You can broadcast an entire folder in this way. All the same “Transfer to device” or “Play to”. The entire folder will go to the playlist. Works for both image and video transmission.

Cinema and TV

Windows 10 has a built-in Movies & TV app that you don’t usually use. But it also has the same “Transfer to” function. Those. you can safely watch a movie and, if you wish, switch to TV:

On previous generations of operating systems, the same functionality is obtained through the beloved Windows Media Player.

What is it for?

In fact, you know better. Personally, I see several possible tasks in this:

  • For watching movies. this is the main purpose. Your computer is far away, there is no wire, you run a movie on it and display it on the TV screen. As for me, it’s better to immediately throw the film on a USB flash drive and stick it into a TV set, but there are all sorts of cases. See the DLNA section right away.
  • Viewing photos together is great.
  • Play games. some people do that. But here it is still better to use a wire, the response will be many times better, and the game will become comfortable. Delays and freezes are possible wirelessly.
  • The second monitor and screen demonstration. just for browsing websites or doing some design work, or maybe for everyday activities (I just have one of the TVs connected to a PC). in general, for work purposes. Here, the delays are not significant either, so you can use.

The section is more for commenting on the fact that connecting a TV over Wi-Fi is not always a good idea. Sometimes it’s easier to consider using a wire or find an alternative (like watching movies through a USB flash drive).

Everything has been successfully tested on Windows 7 and Windows 10.

Using Miracast and Intel WiDi

  • Turn on Miracast. WiDi on the TV. Some models turn them on by default. For some reason, everything was turned off on my LGs. On Samsung it is generally called differently. “Screen Mirroring”. But the main thing here is to go into the settings, try to find and enable. If it is turned on or there is nothing like that, it’s okay, but they checked.
  • For Miracast. Everything is in the box initially. We click on the notifications in the lower right corner (Windows 10), select “Send to screen”, then “Connect to a wireless display.” We select our TV and connect. The TV may prompt you to connect.
phone, does, wi-fi
  • For WiDi. You need to download the program from Intel “Wireless Display” and through it display the screen:

Everything connects, the screen is duplicated, but delays In general, not very good for games, but if you need to watch movies, there is DLNA technology.

The TV does not connect or does not see the Wi-Fi network, what can be done.

Good day!

How To Mirror Phone To TV (No Wifi, Cable or Chrome Cast Needed)

The most common way to connect TV to the Internet is to use Wi-Fi wireless technology. However, in some cases, the TV either does not see the network we need, or even after connecting to it, it still remains without the Internet.

Actually, since There are a lot of questions on such a problem (and especially they have become more frequent after the transition to digital television), I decided to sketch this small note.

Going through it sequentially (according to the steps below). I think many users will be able to fix this problem on their own (and save some money without paying for the services of specialists).

By the way, I can’t help but note that in order to connect a TV to the Internet, it must have a Smart TV function. To find out if it is there, just look at the TV specifications (how to find out the exact TV model).

TV does not see Wi-Fi network at all

This is the most common type of problem. Usually it consists in the fact that when you want to connect to Wi-Fi, the TV simply does not find it and does not display it in the list of available ones (or, less often, it is grayed out and cannot be connected to it.).

Among the list of networks (which TV sees). yours is not there.

check the range of the router (2.4 and 5 GHz) and the working channel

Modern routers can operate in two bands: 2.4 GHz and 5 GHz (the latter is preferred, since the data exchange rate is higher). However, not all TVs support 5 GHz, therefore, I would recommend turning on broadcasting in 2 bands at once in the router settings.

5 GHz or 2.4 GHz. configuring a TP-Link router

Another important point: TVs for Europe and the CIS can see the 5 GHz network only on 4 channels 36, 40, 44 and 48 (a channel is a special setting in the router that tells it the exact frequency of the network on which it works). If we talk about the 2.4 GHz network, then the operating range is from 1 to 13 channels (For Russia and the CIS).

Channels are also set in the router settings (in the “Wireless mode” section).

Wireless mode. channel settings (TP-LINK router)

By the way, it should be said that if your TV or router is not localized for the countries of Europe or the CIS, it is possible that it “does not see” some of the channels. Try alternately as an experiment to change several channels in the web interface of the router.

Setting up a channel in a Wi-Fi router, how to choose a free one: or why frequent Wi-Fi cuts, low speed, poor quality of coverage.

TV sees Wi-Fi network, but does not connect: error

Double-check the name of the network and the password for accessing it (one friend of mine stubbornly wanted to connect to a neighbor’s Wi-Fi network (the network was called almost the same as his )). It is very convenient to use a Wi-Fi-enabled mobile phone for this.

In general, also pay attention to the error code (if displayed) and its description. In some cases, only this code allows you to get to the “truth” (especially when developers have made some mistakes in the software).

Next, check the router settings (tab “Wireless settings”). Is the name of the Wi-Fi network and the password correct when you try to connect the TV?

By the way, as a diagnostic, I would recommend changing the name of the network and its password. After that, immediately try to connect the TV (as the first device) using these changed data.

Also, take a look at the “Bandwidth Control” settings section. If there is a similar option in your router model. in some cases it may start blocking access to the Internet for certain devices (including TV).

If you do not know how to disable it (or cannot find it at all), try resetting the router settings to default.

Bandwidth control (Tenda router as an example)

In some cases, the old settings “do not allow” to establish a network connection (if the TV was previously connected to another network). To accurately eliminate the causes associated with this, it is recommended to reset the TV parameters for diagnostics:

  • LG TVs have the following menu: “Settings. Advanced. General. Reset to factory settings”;
  • for TV Samsung: “Support. Self-diagnosis. Reset” (see screenshot below).

By the way, when you reset the TV settings, not only the network parameters will be cleared, but also the TV channel lists. You will have to re-configure them.

Try to use WPS technology instead of a regular connection to a Wi-Fi network (with entering a password in manual mode). In short: then by pressing the special. button on the Wi-Fi router and TV. the devices will automatically connect to each other.

Conveniently?! Undoubtedly! In addition, in such cases as ours, it saves a lot of time.!

    first you need to go to the TV settings and turn on WPS;

then press the “WPS / Reset” button on the router for 1-3 seconds. (no longer, because this can lead to a reset of the settings!);

WPS button on different router models (layout options)

  • if everything went well, in a few seconds the TV will have access to the Internet.
  • phone, does, wi-fi

    WPS button on a Wi-Fi router: why is it needed and how to use it.

    If all of the above did not work, then perhaps, as a temporary measure, you will be satisfied with connecting TV to a phone or computer (which have Internet).

    This will allow you to view movies and photos (which are saved on them), play computer games on a large screen, surf the Internet, looking at Internet pages at their full size.

    I gave a couple of articles on connection and configuration below.

    In rare cases, the fault of the TV’s incorrect operation with the Internet may be the firmware (i.e. the software that is installed in the device). To eliminate this defect, you need to download the correct firmware from the manufacturer’s website and update it.

    I warn you that such a procedure is often the reason for the refusal of warranty service (moreover, it can cause damage to the TV).

    information about TV firmware:

    does TV see at least one network?

    And the last thing: does your TV see at least one Wi-Fi network at all? If you live in a city (in an ordinary apartment building). you should find at least 3-10 Wi-Fi networks of your neighbors

    If this does not happen, you may have a damaged Wi-Fi module. Alternatively, you can try to connect the TV to the router using a network cable, or use an external Wi-Fi adapter.

    Connecting TV to a router using a network cable

    restart TV and router

    This step is quite trivial, but very effective (after all, when the devices are rebooted, they are re-initialized and paired, which eliminates many software malfunctions).

    By the way, if you do not know how to reboot the Wi-Fi router, then it is enough to disconnect it from the power supply for 20-30 seconds. (this is necessary so that the previous Internet session with the provider was closed).

    check how far the TV is from the Wi-Fi router

    Pay attention to the distance between the Wi-Fi router and the TV: the farther they are from each other, the worse and weaker the signal will be (i.e. the quality of the Internet). By the way, it should be noted that walls, furniture (especially mirrors), and other radio devices can significantly weaken the radio signal.

    Below on the screen I presented a typical layout of a 2-room apartment: on the right. the location of the router is good; left. Not really.

    Location of the router in the apartment: on the right. the option is much better

    In order to diagnose and find the cause of the problem, I would recommend the following:

    • try to take the phone and, being near the TV, also connect it to Wi-Fi (will it see the network? What will be the signal strength?);
    • if possible, move the router closer to the TV (or vice versa). Will there be a signal.

    Replacing the WI-FI adapter with an external one

    This method will not correct the problem 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 WI-FI adapter resembles an ordinary 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 WI-FI. 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.

    A router with 5 GHz support: how it is useful now?

    All of the above, of course, sounds very cool. But in reality, such an Internet simply does not exist yet. at least on the scale when it can be called publicly available. Modern Russian providers offer tariffs for a maximum of 1 Gbit / s, and even those are mainly in the capital.

    READ  Connecting Phone To TV Via HDMI

    If you are lucky enough to be a subscriber of one of the fast tariffs, then a router with support for 802.11ac, tuned to a frequency of 5 GHz, is a must for you. Otherwise, you simply will not get your gigabit. at 2.4 GHz, about half the speed will be “cut off”.

    In addition, the 2.4 GHz band is now overloaded: many routers, all Bluetooth-enabled devices, as well as a host of other equipment, including microwaves, work in it. Naturally, they compete with each other, interfering with each other’s work.

    2.4 GHz router and microwave oven work on the same frequency

    Only Wi-Fi works at 5 GHz. So even if your tariff is not very high, you can buy a dual-frequency router and turn on the distribution of the Internet on it in the 5 GHz range. Then your devices that can “catch” Wi-Fi at this frequency will be able to freely use the Internet without interference.

    Speaking of interference, the 5 GHz Wi-Fi signal is shorter, and this is a real gift in an apartment building. Your Wi-Fi will only work inside your apartment and will not be disturbed by the neighbors’ routers. Most likely, the neighbor will not even see your network in the list of available ones (and will not be able to hack it).

    Finally, with support for MIMO and Beamforming technologies, each of your 5 GHz devices will receive a stable signal on a separate channel directed directly at it. Therefore, despite the lack of speeds, it is already very profitable to use a 5 GHz router.

    TV firmware

    In order for Smart TV services to function correctly and without any disruptions, you need to update the software in a timely manner. There are 2 main methods for updating the operating system firmware: via the Internet or using a flash drive. Step-by-step instructions for installing updates on Samsung TV from a USB flash drive:

    • Open the official web portal of the manufacturer.
    • Enter the model name of the device you are using in the search bar.
    • Switch to the “Support” tab.
    • Go to the “Software” section.
    • Select the latest firmware from the drop-down list.
    • Follow the link to download the update files.
    • Create a folder “Samsung_dTV”, and then upload the downloaded files there.
    • Insert the USB flash drive into the USB connector of the TV.
    • The system will automatically offer to install system updates.
    • Click on the “Run” button.

    Never turn off the TV until the update installation process is complete. It is advisable to use an uninterruptible power supply. Since voltage drops cannot be ruled out.

    Now you know what to do if Wi-Fi is missing on your Samsung TV. If the TV device stops picking up the signal or the Internet speed is very poor, use one of the listed solutions.

    If the user has connected an external Wi-Fi adapter, and the TV does not see the device, then this indicates a compatibility problem. To avoid such difficulties, buy only branded devices. It is advisable to purchase a device from the same company as the TV.

    Checking for 5 GHz Wi-Fi support in your phone via settings and Wi-Fi Info app.

    Wi-Fi 5 GHz is a wireless network that operates on the 802.11ac standard (more detailed description). It provides high speed Internet due to the fact that this frequency is less congested compared to 2.4 GHz Wi-Fi. But how do you know if your phone supports 5GHz Wi-Fi?

    You can find out whether a mobile device supports 5 GHz Wi-Fi or not in several ways:

    • Examine the specifications of the gadget. In the section with information about the network, there should be a note that the device works with the 802.11ac standard. You can find out these data on the official website of the manufacturer or in the instructions that come with the smartphone.
    • You can find out 5 GHz Wi-Fi support in the device settings. To do this, go to the section of the signal frequency range. All the information you need is displayed here. This is true for gadgets that run on Android.
    • Wi-Fi Info app. Through the program, you can see if the gadget has support for the modern wireless network standard. Information is shown in the 5Ghz Support section. True. there is support, False. no.

    As a rule, this standard is supported by all modern gadgets. smartphones and tablets. Check if 5 GHz Wi-Fi is working on your phone or not, you need to on old devices.

    There are 10 main ways to restore WI-FI 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:

    IEEE 802.11 ac standard: what gives 5 GHz frequency?

    Most routers distribute wireless Internet at 2.4 GHz. the same frequency that phones and microwaves emit their waves. This frequency was allocated as a working frequency for old wireless communication standards. IEEE 802.11 versions b, g, n.

    Since 2009, Wi-Fi standards have gradually begun to use another frequency. 5 GHz, and in 2016 the Ministry of Communications of the Russian Federation officially allowed the use of the 5 GHz band for wireless Internet access. 5 GHz frequency support first appeared in the 802.11n standard and became permanent in the latest version. 802.11ac, with which the most current routers work today.

    The new standard is backward compatible with the old ones, so devices that support 802.11ac are able to distribute the Internet in two frequency ranges: 2.4 and 5 GHz. Thus, all gadgets can be connected to them. both new ones that “understand” the 5 GHz frequency, and old ones that can only catch Wi-Fi in the 2.4 GHz range.

    Here are the main advantages of a router that operates on the 802.11ac standard at 5 GHz.

    • Huge bandwidth. up to 160 MHz.
    • MIMO technology. Wi-Fi signal can include up to 8 spatial streams, while at 2.4 GHz there can be only 3.
    • Beamforming technology. the router detects where the device is using the network and directs the signal from the antennas directly to it.

    How to Fix All Wi Fi Problem for Android Smart TV (Not Connected, No Internet, Authentication)
