Samsung TV Keeps Disconnecting From Wi-Fi

An intermittent Samsung TV connection can come from weak signal at the TV, a router problem affecting the whole home, or the TV’s saved network state. Test at the television’s location rather than assuming a phone across the room sees the same signal.

Run Network Status when the problem occurs

On current models, open Settings > All Settings > Connection > Network > Network Status. Older models may put Network under General.

Note whether the diagram or message shows a break:

• between TV and router
• between router and internet
• only inside one streaming app

Then connect a phone to the same Wi-Fi and hold it beside the TV. If the phone also has one or two bars or loses internet, improve the home network rather than resetting the television.

Restart the TV and network

Samsung supports a cold reboot by holding the remote’s Power button until the Samsung logo appears on compatible models. You can also unplug the TV briefly.

For the full network path:

1. unplug the modem, router, and TV
2. start with the device connected to the incoming internet service
3. wait for it to finish booting
4. power the next router or mesh unit
5. power the TV last

This order prevents the TV from reconnecting before the router has internet.

Forget and reconnect Wi-Fi

Open Settings > Connection > Network > Open Network Settings > Wireless. On supported models, open Manage Saved Networks, select the home network, and delete it. Reconnect with the current password.

If the network name changed, remove the old profile. Check that the TV is not joining a guest network, extender with poor backhaul, or neighbor’s similarly named network.

Improve the signal and band

Samsung advises checking signal strength at the TV. Move the router or mesh node into a more open position, reduce walls and metal obstructions, or use a wired Ethernet connection where practical.

If the TV supports both bands, test 2.4 GHz for range and 5 GHz for shorter, less congested links. Restore router settings that changed immediately before the drops. Do not disable security or expose the network.

Reset only network settings first

Use Settings > Connection > Network > Reset Network, then reconnect. Menu paths vary by year and model.

This is narrower than resetting Smart Hub or the entire TV. A full TV reset signs out accounts and changes more settings, so reserve it for a confirmed TV-only problem after software updates and network reset.

Connect briefly by Ethernet if possible. Stable Ethernet with unstable Wi-Fi isolates the issue to wireless signal, router Wi-Fi, or the TV’s wireless hardware. If both fail while other devices work, contact Samsung with the Network Status result.

Frequently asked questions

Why does the TV disconnect while phones stay online?

The TV may sit behind a large panel or cabinet, use a different Wi-Fi band, or have a weaker saved connection. Test a phone beside the TV and run Network Status.

How do I reset just the Samsung TV network?

On many current models: Settings > Connection > Network > Reset Network. Consult the model manual if the menu differs.

Should I enter a manual DNS server?

Not first. Signal, router service, saved network, and restart tests are easier to reverse. Use manual DNS only when a confirmed DNS problem remains.

Will resetting Smart Hub fix Wi-Fi drops?

It is broader than necessary and signs you out of apps. Reset the network first.

When might the TV need service?

When it disconnects on multiple known-working networks, including near the router, after software and network steps—or when Network Status repeatedly identifies the TV side.
