what is los in modem

LOS stands for Loss of Signal, which is an indicator on a networking device that shows a signal or connection is dropped or terminated. In the context of modems, LOS means that there is a problem with the signal reaching the device, and it cannot communicate with the ISP due to signal loss. This can be caused by various reasons, such as unpaid bills, maintenance issues, or loose cable connections. Different modems provide different indications for when there is a loss of signal, and the LOS light blinking red on a Huawei router usually indicates a problem with the fiber optic connection. To fix LOS, one can try restarting the modem, checking for loose cable connections, or waiting for the problem to resolve itself.
