Hi! I have a similar problem: My 50" NU7100 TV seems to forget the wi-fi connection every other time I switch it on. So, to be clear: When I switch it on and try to start any of the apps on it, I just get the error message, telling me that I need to check the connection. After that, I reboot the TV by pressing the On/Off Button on the remote for a few seconds until I see the Samsung logo. After that reboot, the Wi-Fi connection works immediately. I have already reset the SmartHub and the TV is on the latest firmware, as far as the Update tool on the TV goes. As this is the only device, that seems to have problems on my wi-fi, I suspect there is a software issue on the TV. Is there an older firmware I can roll it back to? The problem seems to have occured on one of the latest updates. Thanks!
