I also have had two different Samsung TVs in my den, the newest being a recently purchased 4K model (UN65KS8000), all of which have never had any disconnection problem. I never had this problem with my prior bedroom TV which was another Samsung HD TV in the same spot as my new one.


But why? I have had three other Samsung TVs connected to my same routers without any internet disconnection problem. The only troubleshooting I have not yet tried is a different router. I called Samsung support one time and the agent did not offer any solution. I even exchanged the TV in hopes that there was something defective with my first unit, but the new TV is doing the exact same thing. change settings, use manual or modified IP settings, manually add new or existing network, unplug, factory reset, software updates, use reserved DHCP, try unsecured guest network, etc, etc. I have been troubleshooting for months and tried nearly every possible fix that I can find (e.g. However, when the TV is turned off the internet disconnects.

As long as the TV is turned on, the connection is fine and there are no disconnection problems. I have to re-input my security code each time (or connect using WPS) and the internet then immediately reconnects. When the TV is initially turned on, there is no internet connection even though the router is close by and the wifi signal strength is very strong. My new Samsung 4K TV (UN50KU6300) in my bedroom disconnects from the internet whenever the TV is turned off for even a short period of time.
