How to Fix It
-
Reset network settings: Settings > General > Network > Reset Network.
This clears all saved WiFi data. Reconnect to your network with the current password.
-
Change DNS to Google: Settings > General > Network > DNS > 8.8.8.8.
Samsung TVs sometimes have DNS issues with ISP-provided DNS. Google DNS (8.8.8.8) is more reliable.
-
Restart both the TV and router.
Unplug both for 30 seconds. Plug in the router first, wait 2 minutes, then power on the TV.
-
Try connecting via Ethernet cable to test.
If Ethernet works but WiFi does not, the TV's WiFi module may be faulty.
