These are the common cause why your Samsung TV keep disconnecting from WiFi: old firmware. problems with router DNS settings or MAC address failing. poor internet connection.
If your Samsung TV isn't detecting a wireless network (or continuously loses its network connection), the problem might be that your TV simply isn't properly connected to your network. There are a few things that can lead to connection issues, like old firmware or your smart TV needing a reset.
Power Cycle Network Devices
Like all electronic devices in our homes, routers can glitch, causing them to randomly disconnect from other devices. The easiest way to resolve these glitches is by power cycling your router and modem.
Restart the router. Unplug the power, wait about 1 minute, and reconnect. Try connecting another device to the router. If it works, it's a TV problem, and if it doesn't, it's a router problem.
If your internet keeps dropping, the issue is most likely with your wireless connection, not the device itself. The main reasons for Wi-Fi connectivity issues include a weak Wi-Fi signal, a congested internet service provider (ISP) network or hardware issues.
You can usually find them under Advanced, Power Saving, or a Wifi menu. Most menus have a search field; try typing power-saving or wifi. On some of the highest options, you will notice that wifi is disabled. Either choose a different mode that does not switch wifi off or pick a setting that always keeps it on.
Restart your smart TV and Wi-Fi router
A restart will refresh the settings on your smart TV without erasing any of your data. Just unplug your smart TV, wait 30 seconds, then plug it back in. To restart your Wi-Fi router, unplug it, wait 30 seconds, then plug it back in too.
Using your TV's remote, navigate to Menu, then select Settings, and select Support. Select Software Update, and then select Update Now. New updates will be downloaded and installed on your TV. Updates usually take a few minutes; please do not turn off the TV until the update is complete.
One of the most common causes of random Wi-Fi drops is poor Wi-Fi signal. Your Wi-Fi signal may be weak because your too far from your router, or you may be experiencing interference from obstructing materials or other Wi-Fi networks.

Wi-Fi Protected Setup (WPS) is a feature supplied with many routers. It is designed to make the process of connecting to a secure wireless network from a computer or any other device easily.
Wireless interference (channel overlap) with other WiFi hotspots or devices nearby. WiFi adapter outdated drivers or wireless router outdated firmware. ISP issues.
Your Wi-Fi connection could be cutting in and out, or dropping entirely due to a weak signal, distance from the router, interference from other devices, or outdated firmware. You can try moving closer to the router, reducing interference, updating firmware, or getting a Wi-Fi extender.
Open the Device Manager (You can do this by pressing the Windows but and typing it out) Right click on your wireless adapter and choose Update Driver Software. Choose the option to Browse and locate the drivers you downloaded. Windows will then install the drivers.
Try connecting to a different network. Switch on hotspot on your phone, and then connect to that network via your Smart TV's network settings menu. If the Smart TV can access the Internet over other networks, the issue is likely to be in the router or Internet connection itself.
Additionally, there is also typically a higher bandwidth with a wired connection. Higher bandwidth means quicker connections and no interrupting frequencies from other smart devices. Anyone looking for the most stable connection should consider using an Ethernet cable.
If you are still having issues with your Smart Hub, you can perform a factory reset. When you do this, all Smart Hub settings will revert to their factory defaults and all information related to Samsung accounts, linked service accounts, Smart Hub service agreements, and Smart Hub apps will be deleted.
Restoring your device to its factory default settings will remove all user data. Power on your TV. Press the Menu button. Select Support, then Enter.
