How about a wifi router reboot then try any other WiFi router set to all Defaults. If this fails and the TV does this I'd arrange for service. Why? Prior discussions seem to point me to a service call.
I have a Samsung UE46ES8000 and everything worked fine but today I tried changing the wireless connection and got a very strange error.
Whenever I access the Network Settings menu and search for available wireless networks the TV will find and display available networks for half a second and then completely exits the menu. If I cancel the process and try to add a SSID manually the Network Settings window is closed. It does this every single time.
I tried unplugging the TV, updated the firmware to the latest release and even did a few factory resets.
After a factory reset the TV asks me to choose the Wireless network I want to connect or if I want to connect to the initial network. I can see the full list of available networks but the TV can't connect to any of them (not even the one I was previously connected to if I choose it from the list). After another factory reset I instructed the TV to keep the previous network settings and managed to connect it to the initial wireless network.
I have no idea what is wrong with it or how to fix it. Any thoughts on this issue?
