Hi, If your TV is having trouble maintaining a wireless connection, please try the following: 1. Distance matters – Keep your TV within 50 feet of your router. Avoid placing the router behind walls, furniture, or electronic devices. 2. Minimize interference – Turn off nearby wireless devices that may disrupt the signal. 3. Power cycle both devices – Unplug the TV and router for 30 seconds, then plug them back in. 4. Run diagnostics: o Settings > Support > Device Care > Self Diagnosis > Smart Hub Connection Test o Settings > Support > Device Care > Self Diagnosis > Wi-Fi 5. Update firmware: Settings > Support > Software Update > Update Now 6. Factory reset (if needed): Settings > All Settings > General & Privacy > Reset > Factory Data Reset If you continue to experience issues, please contact Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun).
