You can watch TV on the Internet at home but you can't connect to your mobile phone because the TV uses a wired Internet connection and the mobile phone connects to your home wireless network.
This may be due to insufficient router signal coverage of the home wireless network, causing the phone to be unable to connect to the network. At the same time, there may be too many network connected devices at home, which will also affect the stability of the home wireless network.
It is recommended to enhance the signal coverage of the home wireless network to avoid overcrowding caused by too many connected devices.
