When the LOS light is off, it is in a normal state, which means that the router device has received the optical signal; when the LOS light is flashing red, it is in an abnormal state, which means that the router device has not received the optical signal. , so we can’t access the Internet even when connected to Wi-Fi.

Using a broadband router to share the Internet often disconnects, and the connection to the network can only be disconnected periodically, which indicates that the problem still lies with the broadband router itself. , such as stability and settings.

4. Unable to log in

Cannot log in to the broadband router settings page. If you have successfully entered the setting interface before, please first check the hardware connection between the broadband router and the computer, and set the network card to "obtain an IP address automatically", otherwise the local address must be set to the broadband router.
