hard to say since you haven't shown us any of the configuration you have on ssid. do you have a controller or is it in stand alone setup? in controller mode you create ssid with default settings on everything except ssid name and password and see if it works.

  @MR.S I have a controller in docker.

current ssid config below, just a note that I tried all WPA modes and single band setup andfactory reset the AP's

  @eab69 

It didn't show much, what are WPA Mode and PMF settings

@MR.S Sorry only uploaded one image, below the rest.

Ok, try to make an SSID exactly like this exept SSID :-) this is default settings when create a SSID

Have you done any configuration in site settings under Wireless Features? 

@MR.S Tried it again, something I already did before :-)  Unfortunately it doesn't work. Even tried to set the IP address manually on the TV when trying to connect, without luck. Even security set to none doesn't work.

I toggled most of the settings off on the site settings as well, below current settings:

very strange, I have several samsung tvs in different networks and there has never been any problem with them, even my own tv from 2012 works on wifi,

how is the Beacon Control settings then? is it like this on both 2.4 and 5 Ghz?

  @MR.S thanks for your help. 
the setting for the beacon was on auto, changed that to 100ms, but still no luck. The TV is new and knowing that WiFi works when connecting to Google WiFi AP. Not sure what else I can do. Will also try to contact Samsung, but I bet they will point to tp-link.

I don't know what it could be, what about the firmware on the access point and TV, are they up to date?

  @MR.S all latest versions.

I think I toggled every setting for AP's and switch. Not sure what it can be.
