Router fiber optic signal turns red
If your router's red light is blinking, start by power cycling it—turn it off, wait a few seconds, then turn it back on. Check your cables and connections to make sure everything's secure, and if needed, reset your router to factory settings. The LOS light on your router indicates the status of your internet connection to the Internet Service Provider (ISP). Here are some steps you can take. We will explore common reasons behind the solid red.
