Windows 10 & 8.1 Miracast Issue: Samsung Smart TV Not Detected, Stopped Working - Solutions?

Welcome,
I do not know if I put a topic in a good section, so if I did it wrong, I apologize and I am asking you to move or indicate the right department for this problem.

I wonder if the problem only occurs with me or maybe someone of you also observed something similar, namely I have 2 TV samsung with smart TV. Until now, without any problem, I connected 2 computers with one window, 8.1 with Windows 10 as wireless screens, and thanks to that I could share the desktop on TV. Of course, everything via WiFi. It worked quite well. Ok, 2 weeks I did not use this function, today Friday, I want to cast a movie on TV and here the end, the computer can not see TV. I have removed devices, I want to add them again, windows 10 does not detect TV at all, windows 8 detected TV as a non-certified device. I have no idea what happened. TV updated. I restored the factory settings. Zero effect. Nothing helps. I do not know what else to do anymore. Is microsoft kicked something up in some update, so this function stopped working? Can anyone possibly verify the operation of this option at home? Thank you in advance for your help.

Nothing has changed on the web?

Is the IP of the TV in the same network as the IP of the computer?

Can you ping the TV from your computer?

Yes, I checked it too. TVs are on the same network and the computer can ping them easily . I also tested it on another network and it is unchanged

Maybe the miracast device broke down?

But it's on 2 computers at the same time? It seems unlikely

Miracast is a device plugged into the TV to the HDMI port.
Communicates with the computer via WIFI.

THIS device (connected to the TV to the hdmi port) could be broken,

Try to configure the miracast device again.

As miracast fell on both computers (win10, win8) it is rather unlikely that it would be the fault of software in computers, I would rather point to a device problem.

As miracast is built into the TV, try reconfiguring.

But I have 2 TV and on both is exactly the same problem. Only winows 8 can see them but I can not connect with them because they claim that they are uncertified devices for Windows and the end. And before that he normally connected with them and everything could be shared.

Well, they probably did not get both equipment at once

Try to Disable the wine barrier 10.

Hey,
You know what, it's all getting weird. I turned off the firewall and the situation is as follows (I tested on 2 different networks). TV and computer connection with WiFi network. I have IP from the same subnet. Gate: 192.168.1.1, computer: 192.168.1.101, TV: 192.168.1.104 (ip dynamic). I release PING to the network, pass, release PING on TV, pass elegantly. Ok, I'm going to search. I find TV, I am trying to connect, all the information "Connecting" on the computer and a circus is starting because merging continues all the time and of course it does not connect but something strange happens with the network, ie I lose internet access and I am unable to connect pause neither router nor TV. I can not even enter the router's configuration page. Absolutely nothing. Only when I do a computer reboot or disconnect from the network and connect again it all returns to normal until I try to connect to the TV again. Then the same thing happens. The situation takes place on 2 networks, one Netgear stationary router, the second portable huawei with mobile internet. I give you a word that I did not have such problems before. I could connect to TV without any problems. Anyway, I used it for a few months, watched movies, sometimes TV served me as a second monitor. There were never any problems, nothing broke, it was great. And suddenly something like that.

I forgot to add, this is the message I receive when pinging TV and router in the course of TV together: "Request timed out"

Second WIFI router in the network?
Someone moved the antennae to the router?

connect neta, cmd.exe
ping 8.8.8.8
ping and p-TV
ipconfig / all
arp -a

Wait until it is jammed and ping tv is not responding
ping 8.8.8.8
ping and p-TV
ipconfig / all
arp -a

Scan the WIFI network inssider 2.x where there is a TV where you use a laptop

show all results.

Generally, I solved the problem by restoring the factory settings in the router but it does not mean that I did not want to know what was causing it. I did everything that you wrote about, maybe something that disturbs you. As for routers, they are not on the network. These are two independent routers operating separately.

The results were fresh after connecting to both the computer and TV network (no attempt was made to connect the computer to the TV):






Results during the connection of the computer to the TV (on the computer with W10, the option of searching for a wireless screen which was obviously not found):

Upload the diagram (routers, tv, your computer, other devices, internet connections)

Sorry, I'm reheating, but I'll leave it for posterity. This is not the fault of the router, only Windows 10 and Intel. I write that it works on win8 and on win10 it does not. After one of the updates, it did. You need to combine with the Intel controllers under the wifi card
Intel has ceased to develop WIDI technology, hence Miracast.

What do you mean with this combination with drivers? Do you have a specific solution, where do you get some working drivers from? I have a problem with Lenovo, HP and Samsung ...
Evident Windows 10 fault.

you're misleading a bit. In fact, intel stopped supporting and developing from his WiDi. However, miracast is a completely different technology and how you can read on the official website of the Intel:
[url=]https://www.intel.com/content/www/us/en/support/articles/000021693/emerging-technologies.html[/url]
it is supported natively by Windows 10.
You need to look for a problem with the e-network, it may also be the fault of one of the Windows 10 updates and maybe we will see some amendments soon. Answer a lot after time but now I am looking for a solution myself because this function ceased to work (laptop dell inspirion 5577 and samsung ue55mu6452) while samsung s7 and s9 + phones worked but for a moment had a problem finding a TV for this smart things worked without charge on both . At home, I will try to check the router settings, connect the TV directly to the laptop via the host or use one of the phones as a host for the laptop and tv and write about the effects soon.

As for the miracast connecting forever and unsuccessfully and reporting errors, it helped me on the dell precision 5530 to enable sharing of all network resources and restart the laptop ...

I checked everything, i.e. router settings, network card and I do not know what else ....
