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.
I am having a similar problem, I have had no issues connecting prior but for the past 4 days I cannot get the tv to connect with my Wi-Fi, I have no issues with the Wi-Fi with all my other connected devices, its just the Samsung tv that has problems connecting. I believe I am up to date with the software updates. I have tried all the reboot, restart, manual dns, etc nothing worked . I need help please. Here is my tv info;
Software version: T-KTMAKUC-1240.4
Sub-micom version: T-KTMATSCL-3.0.1
