Some troubleshooting steps to try:
- Move the WiFi router closer to the TV to improve signal strength[1]
- Double check the WiFi password entered is correct[1][3][11]
- Try connecting via Ethernet cable instead of WiFi to rule out wireless issues[1][2][4]
- Restart the router and TV[1][7][11]
- Factory reset the TV to erase any software bugs[5][9]
- Update TV and router firmware[2]
- Temporarily disable VPNs, proxies or antivirus software on TV[5][11]
- Try a different HDMI port or cable if display issues[10]
