I have the same problem. The TV cannot find any WiFi networks. I get the screen where it searches for wifi networks. I click on Start, then it goes right back to the screen where I can only enter start or cancell. I have model UN55ES8000FXZY. My WIFI works on all other devices (Iphone, tablets, etc). I used to be able to have Wifi on this TV, but haven't had it for a long time. The software version is T-ECPAKUC-10570.
I just updated my firmware via USB card. Still did not make a difference My TV still cannot detect any wifi networks. So, I still cannot use apps on the samsung hub. The next TV we get will NOT be a samsung.
