Do you remember a time when you’re so engrossed in watching a movie and you’re so excited, but then it keeps buffering! Irritating, right? That’s precisely what happens when your Samsung TV keeps disconnecting from WiFi.
Various factors cause the Samsung TV to disconnect from WiFi, including a bug, misconfigured settings, or an overload of devices. To fix this, unplug the unit, reset the internet connection, update the software, or do a factory reset.
As you can see, there are many causes and solutions to this issue, so we’ll show you 10 proven fixes to help you resolve the WiFi disconnection issue on your Samsung TV in less than an hour!
1. Power off and on your Samsung TV.
Powering off your Samsung TV and turning it back on is one of the first things we recommend you do when troubleshooting its WiFi connectivity issue. This method is an effective first-aid solution for fixing minor errors and bugs on your Samsung.
Plus, it’s also quick and easy to do, which makes it the perfect troubleshooting trick to perform first. Doing so allows your Samsung TV to shut down everything in its system, such as apps and processes, to refresh itself once it reboots.
The best way to power off and off your Samsung TV is to conduct a soft reset or restart. Follow the steps below to do these!

2. Troubleshoot your Samsung TV’s internet connection.
The internet connection you’re connected to can run into all sorts of issues, which might explain why your Samsung TV keeps disconnecting from WiFi. Thus, internet issues can be resolved by addressing them directly.
One way to do this is to switch from a 2.4GHz frequency network to a 5GHz frequency network. WiFi networks that use a 2.4GHz frequency band are susceptible to signal interference due to most wireless devices using the same type of frequency.
This overlap causes the frequency band to be overcrowded, resulting in frequent WiFi disconnections due to interference. Luckily, not as many wireless devices use a 5GHz frequency band, making it less likely to get disconnected.
If the internet connectivity issue is due to your WiFi modem and router malfunction, you must conduct a soft and factory reset on both devices. We also recommend contacting your ISP if the issue results from technical difficulties on their end.

If your Samsung TV keeps disconnecting from WiFi networks, it’s likely the result of misconfigured network settings. It can happen when you or somebody else accidentally changes any configuration on the network settings of your Samsung TV.
The tricky part of this problem is identifying which network settings to change to fix the WiFi disconnection issue. We highly recommend resetting your Samsung TV’s network to its default factory settings to return it to its previous working state.
Resetting your Samsung TV will delete your network settings and save WiFi connections. Once the network reset ends, you must reconnect to your WiFi connections and reconfigure the network settings.
| Step 1: Open Samsung Smart Hub on the display screen by clicking Home  on the TV remote control. |
Step 2: Go to the system settings menu by scrolling left/clicking Settings. |
Step 3: Go to the general settings menu by scrolling down/clicking General. |
Step 4: Go to the network settings menu by scrolling down/clicking Network. |
| Step 5: Reset the network settings on your Samsung TV by scrolling down/clicking Reset Network.  |
| Step 6: Confirm the Samsung TV network reset by clicking Yes in the confirmation pop-up.  |
That should be easy. Still, if the issue remains, the next solution should be more potent.
4. Place your WiFi modem/router closer to the Samsung TV.
All WiFi networks transmit a signal to a limited range around it for your wireless devices to receive and connect to. Placing your modem and router away from your devices could explain your Samsung TV/WiFi disconnect.
Thus, we suggest placing your WiFi modem and router closer to the location of your Samsung TV. If you think your WiFi modem and router are already placed strategically, move your Samsung TV to reduce the distance between them.
As we suggested earlier, doing so is especially helpful when connecting to a 5GHz frequency network. While 5GHz networks can provide faster internet speeds, they’re also limited by their shorter range and rely on being close to your devices.
5. Use a public DNS server on your Samsung TV.

| Things needed | TV remote |
Manually setting up the DNS server settings on your Samsung TV helps you use the fastest option that suits your location. You can choose between the most popular public DNS servers and stick to the one that works best on your Samsung TV.
The Cloudflare DNS server is considered the fastest among all available options, but that may not be the case in your location. Since DNS servers work differently based on your origin, it’s better to determine the best one yourself.
With that, we also recommend trying out the public DNS servers of Google and Quad9. You can swap between these DNS servers to determine which is better to use when your Samsung TV keeps disconnecting from WiFi networks.
| Step 1: Open Samsung Smart Hub on the display screen by clicking Home on the TV remote control. |
Step 2: Go to the system settings menu by scrolling left/clicking Settings. |
Step 3: Go to the general settings menu by scrolling down/clicking General. |
Step 4: Go to the network settings menu by scrolling down/clicking Network. |
| Step 5: Select/click Network Status and let your Samsung TV check the status of your network connection.  |
Step 6: Go to the Internet Protocol settings by selecting/clicking IP Settings. |
Step 7: Scroll down/click the DNS setting. |
Step 8: Select/click Enter manually to input a DNS server yourself. |
Step 9: Enter the Cloudflare public DNS server (1.1.1.1) and click Done to confirm. Note: You can also use Cloudflare’s second public DNS server (1.0.0.1). We also recommend trying the public DNS server of Google (8.8.8.8) and Quad9 (9.9.9.9) to see what works best on your location. |
6. Avoid overcrowding the WiFi network.
While most WiFi networks can support multiple connected devices simultaneously, avoid connecting a lot. Connecting too many wireless devices might explain why your Samsung TV keeps disconnecting from WiFi networks.
Even when the limit hasn’t been reached, you can already start experiencing internet connectivity issues such as slow loading. It’s likely to happen to WiFi networks subscribed to cheap data plans with average internet speeds.
You can avoid the WiFi disconnection issue on your Samsung TV by reducing the number of wireless devices connected to your network. Whenever you start experiencing any connectivity issues, this should also be your go-to solution.
7. Set the Samsung TV IP settings to “Obtain automatically.”
