automatically connect to the device in general. Due to the high heat of the ADSL modem, the hand is very hot when it is touched. To work stably with the equipment, it is still placed in a well ventilated place. Because the IP address of ADSL is dynamically allocated, sometimes the IP address needs to be adjusted, and a sudden disconnection may occur, after a few seconds, you can connect automatically. If you cannot connect, press reset Io to close the connection and start the connection. If the
