When your Samsung QLED TV won't connect to the internet, all your streaming apps and smart features are locked out. The issue can be the TV not finding your network, connecting but having no internet, or dropping the connection randomly. Here are the most effective ways to get back online.
Restart Your TV and Router
Unplug your Samsung QLED TV from the wall outlet for a full minute. While you're waiting, unplug your router and modem for 30 seconds as well. Plug the modem and router back in first, wait for them to fully boot, then plug the TV back in. This power cycle clears temporary glitches in both the TV's network module and your home network.
Check Your Network Password
Double-check you're entering the correct WiFi password on the TV's on-screen keyboard. It's easy to make a typo with a remote. Pay close attention to uppercase letters and special characters. If you recently changed your router's password, you'll need to update it on the TV as well.
Forget and Re-add the Network
On your TV, go to Settings > General > Network > Open Network Settings. Select your WiFi network name and choose Forget. Then, scan for networks again and select yours to re-enter the password. This creates a fresh connection profile, which often resolves issues where the TV connects but has no internet access.
Test Your Internet Connection
Use the built-in network diagnostic tool. Go to Settings > General > Network > Network Status and select IP Settings or run the diagnostic. It will check the connection to your router and to the wider internet, helping pinpoint where the failure is happening.
Switch WiFi Bands
If your router broadcasts both 2.4GHz and 5GHz networks, try connecting to the 2.4GHz band. The 5GHz band is faster but has a shorter range and doesn't penetrate walls as well. If your TV is far from the router, the 2.4GHz signal is often more reliable for a stable connection.
Update Your TV's Software
Outdated software can cause network bugs. Go to Settings > Support > Software Update. If you're connected to the internet, select Update Now. If you can't connect at all, you can download the latest firmware from Samsung's website onto a USB drive and update manually.
Change the DNS Server
A slow or unresponsive DNS server from your ISP can cause connection problems. In your TV's network settings, under IP settings, change DNS from automatic to manual. Enter 8.8.8.8 for the primary DNS and 8.8.4.4 for the secondary. This uses Google's public DNS, which is often faster and more reliable.
Use a Wired Ethernet Connection
For the most stable connection, plug an Ethernet cable directly from your router into the TV's LAN port. This eliminates WiFi interference entirely. If your router is in another room, a powerline network adapter kit can send the internet signal through your home's electrical wiring.
Check for Router Compatibility Issues
Some newer routers with advanced security features or specific WiFi 6/6E settings can have compatibility issues with smart TVs. Try temporarily disabling features like "Smart Connect" (which bands devices automatically) or "WPA3" security on your router, reverting to WPA2, to see if your TV can connect.
Reset the TV's Smart Hub
This resets all smart features, including network settings, without doing a full factory reset. Go to Settings > Support > Device Care > Self Diagnosis > Reset Smart Hub. You'll need to log back into your Samsung account and apps afterward, but it can clear deep-seated software conflicts.
