I have a problem with my Dell laptop using Intel(R) Wireless-AC 9560 160MHz cart. Everytime when I try to connect with samsung tv unisng Win+K key I have an erro: "can't establish connection" and in windows log event I have a warning:
"6062 - Lso was triggered" with detailed information:

Intel(R) Wireless-AC 9560 160MHz
I use windows 10 (20H2), newest wifi driver (184.108.40.206). I never use this functionality before so I don't know if the problem existing from beginning or not.
I can try and assist with this. The feature you are referring to is the ability for Windows to "project" it's video to a different device, something other than the laptop display. What will be useful is for you to run the Intel System Support Utility. The SSU collects hardware and OS information from your laptop, nothing that is sensitive information. The link to the SSU is here: https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-
Run the SSU, leave the defaults and click Scan, then click Next, and Save. After you save the file, please post back and add that file as an attachment.
And just in the event there is some known issue, what model Samsung TV are you projecting to?
thank for reply. In attachment I send a file that you ask. Model of Samung is Samsung Q60 Series (55).
I also try to connect to this TV using a new laptop just bought (Dell Latitude 3410) and after reinstall new clean Win 10 OS (only with newest drivers) and laptop just connecting to tv without any problem.
I read over the SSU report. It appears you are using a driver for the AC-9560 that was not released by Dell. Often, laptop manufacturers release drivers that are designed specifically for their hardware. I also see the laptop's BIOS appears out of date. What I would recommend is using the Dell update suite that was provided with the laptop to bring the laptop up to current versions of Dell software. You may need to manually download the Dell network driver, uninstall the latest Intel driver(s), and then install the Dell package. It really is advised to use the Dell tools for maintaining drivers.
I am including the link I found for Dell Latitude 5400 software. The page is in English so you may need to change to the proper locale. Here is the link: https://www.dell.com/support/home/en-us/product-support/product/latitude-14-5400-laptop/drivers
Since projecting involves the graphics/video system of the laptop, I checked your video driver version. You are using a 2019 video/display driver. Dell has a newer version that is dated January 18, 2021. It's definitely worth updating your video driver to see if that corrects the problem. Again, the link to the Dell updates is here: https://www.dell.com/support/home/en-us/product-support/product/latitude-14-5400-laptop/drivers
Select the Video category. You should see the driver information and download.
I've been combing Internet to get some ideas, and learned a bit about the projecting to TV and how it works. The "project" feature is really using Miracast. I also read where others with the same wireless adapter also encountered LSO was triggered. There was no one solution that seemed to help everyone. A few things were mentioned, so I will list them here.
It was suggested to reset the PC's network. That really could make sense on a PC that has undergone several updates. To do a network reset, go to Settings, Network & Internet, and at the bottom of the page you should see Network reset. Click that, and you will be notified that the PC will restart in a few minutes. Allow the PC to do the restart. You will likely need to reconnect to the wireless in your house after the network reset.
If that doesn't work, the next step would be to use the Network troubleshooter. Select the wireless adapter if prompted to do so. Allow the troubleshooter to work and see if that resolves your issue.
Depending on how important and urgent it is that you be able to project to the Samsung TV, the fastest solution may be what you did with the other Dell laptop, and just save your volatile data, and put on a fresh install of the OS. I'm not a fan of just reinstalling an OS because of the need to reinstall so many other pieces of software.
If you are willing to press on and try to make it work, the next step I would recommend is to completely remove the wireless adapter, and then install the latest driver package from Dell. If that fails, then a reset of the TCP and IPv4 components of the laptop's network. To do that, open CMD with administrator privilege. Then enter the following two commands:
netsh int ipv4 reset
netsh int tcp reset
I look forward to seeing what success you get.
