A smart TV that won’t connect to WiFi is surprisingly common, and usually fixable without calling anyone out. Work through these steps before assuming something is broken.
Start with a proper restart of everything
Before doing anything else:
- Turn the TV off using the remote, then unplug it from the wall completely (not just standby)
- Unplug your router from the wall
- Wait a full 60 seconds
- Plug the router back in and wait until all its lights are settled (usually a minute or two)
- Plug the TV back in and turn it on, then try connecting to WiFi again
This clears both devices’ network state and resolves a surprising number of connection problems.
Forget the network and reconnect from scratch
If the TV can see your WiFi network but won’t connect, or connects but loses connection frequently, try forgetting the network and starting fresh.
On most smart TVs, go to Settings > Network > WiFi (or similar, as the exact menu varies by brand), find your network name, and select Forget or Delete. Then reconnect as if for the first time, entering your WiFi password again.
This helps when the TV has stored old or corrupted connection settings.
Check your WiFi password
WiFi passwords are case-sensitive. A capital letter in the wrong place will prevent connection. When entering the password on the TV’s on-screen keyboard, go slowly and check each character.
If you’re not sure what your password is, it’s usually printed on a sticker on the back or bottom of your router. It may be labelled WiFi Key, Wireless Key, or Password.
Check the TV can actually reach your router
Smart TVs often have weaker WiFi antennas than phones and laptops. Just because your phone has full signal in the living room doesn’t mean your TV does, especially if your router is in a different room or on a different floor.
Try temporarily moving your router closer to the TV (or vice versa) and testing the connection. If it works when close but not from across the house, distance and obstacles are the problem.
Solutions:
- WiFi extender: a plug-in device that repeats your WiFi signal further into the house
- Mesh WiFi system: a more capable version of the above, covering the whole home
- Ethernet cable: if your TV has an ethernet port (most do), a wired connection is the most reliable option
- Powerline adapter: runs the connection through your house’s electrical wiring, good when running a cable isn’t practical
Try changing the DNS settings
Your TV uses DNS servers to look up websites and streaming services. Sometimes the default DNS from your internet provider is slow or unreliable.
On most smart TVs: go to Settings > Network > IP Settings (or similar) and switch from Automatic/DHCP to Manual. Enter 8.8.8.8 as the primary DNS and 8.8.4.4 as the secondary (these are Google’s DNS servers, free and reliable). Leave other settings as they were and save.
This sometimes resolves issues where the TV connects to WiFi but streaming apps won’t load.
Check if the problem is WiFi or the apps
There’s a difference between the TV not connecting to your WiFi at all, and the TV connecting to WiFi but specific apps not working.
If the TV shows it’s connected but Netflix, BBC iPlayer, or other apps aren’t loading:
- Check whether those services have any outages (search for “[service name] down” on your phone)
- Try a different app. If one works and another doesn’t, it’s likely an app issue rather than a network issue
- Check if the app needs updating, as older app versions sometimes lose compatibility with streaming services
Factory reset as a last resort
If nothing else works, a factory reset returns the TV to its out-of-box state, which often resolves persistent connection problems caused by corrupted settings or firmware.
Warning: this will delete all your accounts, app logins, and settings. You’ll need to set everything up again. Only try this after exhausting the other options.
Most TVs have the factory reset option under Settings > System > Reset or similar. Consult your TV’s manual if you can’t find it.
