LG WebOS UJ630V Wi Fi Stays Off and I Cannot Connect to Any Networks

My LG WebOS UJ630V TV does not connect to Wi-Fi. The Wi-Fi remains permanently off, and I cannot connect to any networks. Although I have Wi-Fi at home, I cannot use it on my TV. I have tried restarting the TV, resetting the network settings, and even updating the software, but nothing works. It is incredibly frustrating not being able to access streaming services or even simple internet features on a smart TV. I believe this is a chronic issue with LG TVs, and I urgently need a solution. I am in a difficult situation and request that the necessary actions be taken as soon as possible.
