I have a TU8000 TV - Model #UN55TU8000FXZA. Previously, the TV was connected to the internet no problem, and now the TV will not connect to the internet. It keeps telling me the Wifi password is incorrect, but I know the Wifi password is correct. All the computers and devices are connected to the internet, so I know the password is correct. Yet, no matter what I try, I cannot get the TV to recognize the Wifi password. I have tried reseting the entire TV along with a host of other solutions, and every time it tells me the Wifi password is incorrect. At a loss for what to do.
