When a Smart TV keeps losing its Wi-Fi connection, the cause is often the network rather than the TV itself. A few quick checks will show you where the problem is, and many of the fixes take only a few minutes.
Is it the TV, the router or the internet?
- Other devices also drop out or are slow: the problem is likely your router or internet connection.
- Only the TV drops out, while other devices near the TV are fine: the problem is more likely the TV’s settings, software or Wi-Fi hardware.
- The TV drops out only in some apps: the app or the streaming service may be the problem.
Common causes
- A weak signal where the TV is. Distance, walls and furniture weaken Wi-Fi, and TVs are often far from the router.
- Interference or a busy network. Neighbouring networks and other devices can crowd the 2.4 GHz band in particular.
- The Wi-Fi band. 2.4 GHz reaches further but is slower and more crowded. 5 GHz is faster but has a shorter range. Some older TVs only support 2.4 GHz.
- Outdated TV software. Software updates can fix connection problems.
- Router problems. Routers sometimes need a restart, and older routers may struggle when many devices are connected.
- A Wi-Fi fault in the TV. This is less common, but possible if the TV can’t find any networks at all.
What you can try
1. Restart the router and the TV
Switch both off at the wall. Switch the router on first and wait a few minutes until it’s fully connected, then switch on the TV.
2. Check the signal strength at the TV
Most Smart TVs show the signal strength in their network settings. If it’s weak, try moving the router closer or higher up, or consider a Wi-Fi extender or mesh system.
3. Use a network cable if you can
Most Smart TVs have a network (LAN) port. A cable from the router to the TV usually gives a more stable connection for streaming than Wi-Fi.
4. Try the other Wi-Fi band
If your router has both 2.4 GHz and 5 GHz networks, try connecting the TV to the other one. 2.4 GHz is often better when the TV is far from the router, and 5 GHz when it’s close.
5. Update the TV’s software
Look for a software or firmware update in the TV’s settings and install it. Where to find it differs between brands; it’s often under Support or System.
6. Forget the network and reconnect
Remove the saved Wi-Fi network from the TV, then connect again and type the password carefully.
7. Check the date and time
A wrong date or time on the TV can stop apps and secure connections from working. If your TV has the option, set the time to update automatically.
8. Check power-saving network settings
Some TVs switch off network features in energy-saving or standby modes. If your TV loses its connection after standby, check these settings in its manual.
When to contact your internet provider
If other devices also lose their connection, or the internet is slow throughout the house, contact your internet service provider. They can check your line and router.
When the TV may need a technician
- The TV can’t find any Wi-Fi networks, even close to the router.
- It still disconnects when it’s connected with a network cable.
- The problem started after a power surge, or along with other faults.
