When your Samsung Neo QLED TV won't connect to the internet, all those streaming apps and smart features become useless. Whether it's failing to find your network, connecting but having no internet, or dropping the signal constantly, these steps will get you back online.
Restart Your TV and Router
Start with the basics. Unplug your Samsung TV from the wall outlet for a full minute. This is more effective than just using the remote to turn it off, as it clears the TV's temporary memory and resets the network hardware. While you're waiting, unplug your router for 30 seconds too. Plug the router back in first, wait a couple minutes for it to fully boot, then plug your TV back in.
Forget and Reconnect to Your Network
Navigate to Settings > General > Network > Open Network Settings. Select your WiFi network and choose Forget. Now, scan for networks again and select yours to re-enter the password from scratch. This fixes issues where a corrupted network profile is causing the problem.
Check Your WiFi Password and Band
Double-check that you're entering the correct WiFi password, paying close attention to capitalization. Also, see if your router broadcasts both a 2.4GHz and a 5GHz network. The 5GHz band is faster but has a shorter range. If your TV is far from the router, try connecting to the 2.4GHz network instead for a more stable, longer-range connection.
Run the TV's Self Diagnosis
Samsung TVs have a built-in diagnostic tool. Go to Settings > Support > Device Care > Self Diagnosis. Run the Network Test. This tool can identify if the issue is with your network signal, your internet connection, or the TV's own network hardware, giving you a clearer direction for the fix.
Update Your TV's Software
Outdated software can cause all sorts of connectivity bugs.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 your TV manually using the same menu.
Change Your DNS Server
Sometimes the default DNS servers from your internet provider are slow or unreliable. In your TV's network settings, after selecting your network, choose IP Settings and change DNS setting to Enter manually. Set the primary DNS to 8.8.8.8 and the secondary to 8.8.4.4 (Google's public DNS). This can resolve pages that won't load.
Check for Router Interference
Other electronics can interfere with your WiFi signal. Make sure your router isn't tucked directly behind the TV, especially not in the media cabinet where the TV's own electronics and metal shielding can block the signal. I'd also try moving any wireless speakers, baby monitors, or microwave ovens away from the path between your router and TV.
Use a Wired Ethernet Connection
For the most reliable connection, use an Ethernet cable. Plug one end into an open port on your router and the other into the LAN port on your Samsung TV. If your router is in another room, powerline network adapters that use your home's electrical wiring can be a great alternative to a long cable run.
Reset the Smart Hub
This resets all your smart TV apps and network settings without affecting your picture calibrations. Go to Settings > Support > Device Care > Self Diagnosis > Reset Smart Hub. You'll need to log back into your Samsung account and your streaming apps afterward, but it often clears deep-seated glitches.
Perform a Full Factory Reset
If all else fails, a factory reset will wipe the TV back to its out-of-the-box state. Be warned, this will erase all your settings, including any custom picture calibrations you've done for different inputs. You can find this option at Settings > General > Reset. After the reset, you'll walk through the initial setup again, including connecting to your WiFi network.
