Plenty of factors influence the performance of television but if your Samsung Smart TV keeps losing Internet connection, one of the following may be responsible


If you turn off your Samsung Smart TV with the remote for a period of time, there is a chance that a bug would manifest. This bug corrupts the network settings of your television and the loss of the Internet connection is a possible consequence. Fortunately, you don’t have to use much effort to get rid of the bug.

MAC Block 

For your information, MAC stands for Media Access Control and each device that supports connectivity receives a unique MAC address. In the case that your Internet Service Provider blocks the MAC address of your Samsung television for some reason, it cannot connect to the Internet.

Improperly Configured DNS 

To hook up your Samsung Smart TV to the WiFi network and secure Internet connection, you need to properly configure its DNS settings in advance. If you mess up the configuration, conflicts inevitably surface between your television and the router of the WiFi network which affects connection to the Internet.

Router Location, Setting, Bandwidth, …

Everything seems to be in order with your Samsung television? If that happens to be the case then the router should be the one responsible for the loss of Internet connection.

For example, your Samsung Smart TV would have a hard time connecting to the router if the distance between them proves to be too big. In addition to that, the Guest Mode on a couple of routers could get in the way of the Internet connection setup of Smart TV. Lastly, if you connect multiple devices to the router at once, its bandwidth may be congested and prevent your television from having a steady connection.
