When your Samsung Smart TV won't connect to WiFi, your streaming plans are on hold. Whether it's not finding your network, connecting but having no internet, or dropping the signal constantly, these steps will get you back online.
Perform a Soft Reset
Hold down the power button on your Samsung remote for about 10 seconds. The TV will turn off and then back on. This is a quick way to clear temporary glitches without unplugging anything, and I'd start with this one.
It's essentially a forced reboot for the TV's smart functions. This can resolve minor software hiccups that are preventing the WiFi chip from working correctly.
Power Cycle Your TV and Router
Unplug your Samsung TV from the wall outlet. Don't just use the remote. While it's unplugged, also unplug your router and modem from power. Wait a full 60 seconds before plugging everything back in.
Start with the modem, wait for its lights to stabilize, then plug in the router. Finally, plug your TV back in. This process clears the memory cache on the TV and gives your entire home network a fresh start.
Run the Built-In Network Diagnosis
Samsung TVs have a helpful self-diagnosis tool. Grab your remote and go to Settings > Support > Self Diagnosis.
Select Network Status or IP Configuration and run the test. The TV will check its connection and often provide a specific error code or suggestion, which can point you toward the right fix.
Forget and Reconnect to Your Network
Navigate to Settings > General > Network > Open Network Settings. Find your WiFi network in the list and select it.
Instead of entering the password, look for an option to Forget or Delete the network. Once it's removed, scan again, select your network, and carefully re-enter your password to establish a fresh connection.
Check for TV Software Updates
Sometimes a bug in the TV's firmware is the culprit. Go to Settings > Support > Software Update.
Select Update Now. If your TV can't connect to WiFi to download an update, you can download the latest firmware from Samsung's website onto a USB drive and install it manually through the same menu.
Switch Your WiFi Band
If your router broadcasts both a 2.4GHz and a 5GHz network, try connecting to the other one. The 5GHz band is faster but has a shorter range and doesn't penetrate walls as well.
The 2.4GHz band is slower but has much better range. If your TV is far from the router, forcing it to connect to the 2.4GHz network often solves intermittent dropout issues.
Change the DNS Server on Your TV
Slow or unresponsive DNS servers from your internet provider can make it seem like your TV has no internet. In your TV's network settings, look for an option to set the IP or DNS manually.
Change the DNS setting from automatic to manual. Enter 8.8.8.8 as the primary DNS and 8.8.4.4 (Google's DNS) as the secondary. This can significantly improve connection reliability and speed.
Check the Router's Wireless Settings
Certain router security protocols can be incompatible with older smart TVs. Log into your router's admin page (usually via a web browser) and check the wireless security setting.
If it's set to WPA3, try switching it to WPA2/WPA mixed mode. Also, avoid using special characters or spaces in your WiFi network name (SSID), as some TVs have trouble with them.
Use a Wired Ethernet Connection
For the most stable connection, plug an Ethernet cable directly from your router into the port on the back of your Samsung TV. This eliminates wireless interference and distance problems entirely.
If your router is in another room, a powerline network adapter kit can use your home's electrical wiring to extend a wired connection to your TV without running long cables.
Reset the TV's Smart Hub
If the issues seem tied to apps crashing or the SmartThings platform, resetting the Smart Hub can help. Go to Settings > Support > Self Diagnosis > Reset Smart Hub.
This will not delete your installed apps or network settings, but it will log you out of all your accounts and clear the app data cache, which can resolve software conflicts affecting connectivity.
