If the TV cannot connect to the 2.4GHz band wifi network successfully, please follow the below methods to do the troubleshooting:
- Check whether the TV could connect to the 5GHz band wifi network from the same wireless router. In addition, please confirm whether your mobile phone can connect to this WiFi.
- Please ensure that there are no special characters in the SSID and the wifi password, such as *&^%$#.
- Please check the Time and Date on the TV. If it is incorrect, please try to correct it.
- Try to restore the TV back to the factory settings: press the Home
button on the TV remote. Then select Settings-->Device Preferences-->Factory Reset.
If the issue cannot be resolved, please feel free to call the TCL hotline for further help.
