Samsung TV won't connect to wifi network

[Sasa_4]

Hi! I have an issue with my Samsung TV. Since about two weeks it can't connect to wifi anymore. The issue is that it searches for wofi networks but doesn't find any, it just exits the search. I contacted samsung support already, they told me that the tv was faulty. As my warrancy expired I lost all hope, but today, I tried it once more and it actually found all available networks and connected succesfully to mine but only for about 5 minutes and then the old issue came once more.
I have already gone through the forum and tried the suggested sollutions (setting the wofi area to A, manually setting DNS to 8.8.8.8, 4.2.2.1, factory reseting the TV), but none of them worked.
Any further suggestions would be appericiated.

You have done all you could.

Hookup with hardwired ethernet if it has one or a USB-WIFI dongle, consult manual whether this is do-able.

Thanks for the reply! I will try with USB-WiFi.
