Thank you Nothrem, for giving us the Windows service file name to allow through the firewall . That worked for me like a charm - great surprize.
People, you do not need to care about changing the WiFi driver from Intel to Microsoft one. I tried that, and the older MS driver did not help. Stick to the newest Intel.
So, only this trick solved my problem with connecting to S8 Ultra, via standard Windows Wireless Monitor app (Win-K). I do keep the Samsung Second Screen app installed - and it does not harm much. Will test that up later, but standard MS works.
But note this: if you have some anty-viris software, like I have - it can stay on. I repeat. The virus protection can stay on. But often, such a software also has a firewall, that takes over the functionality of standard Windows Defender Firewall. You need to note that in the Windows settings. In such a case, manipulating in the settings of Windows Firewall , will not help.
Instead, go to the settings of your firewall in your custom protection software, and add the exception rule there. Use the great hint that Nothrem provided - the file name. Add the service via the file name. Allow trafic in both directions , and both for TCP/UDP.
You can also add the notiffication - if that particular rule of the custom firewall is reached. I added this, and everytime I connect to the S8+ Tab for second screen , I get this in Windows:
This also pops-up from time to time, when I do not use the laptop for a while , and it needs to re-establish the connection.
Try with the firewall disabled first, and then - if works, add this exception rule and enable the firewall.
It is just it , really. Just this service, that is needed.
Good luck people and enjoy.
TM.
