Just a quick post to let you know that the same thing has happened to my LG TV after the recent update. WiFi doesn't work at all. In network settings WiFi is disabled, and when I try to enable it the TV freezes.
I had the same issue in my 4k lg tv. Now it works flawlessly. It is unbelievable but the solution is to open the tv and extend the flat ribbon cable that goes from the mainboard to the wifi card. This cable comes bended multiple times from factory. You just have to unroll it and route it with gentle and big bending radius. It is basic theory of transmission lines. At high freq. you shouldn’t roll the cable with small bending radius. I was desperate and did it as a last resort. The internet connexion now works without buffering stops. Good luck!
WiFi not connecting. No available networks is showing.
