A router blinking red usually means there is a problem with the router. Here are a few things that can cause your router to blink red:
1. Connection problems: A red light flashing on your router may indicate that there is a problem with your Internet connection. You can check to see if your device is properly connected to the router's network, or try reconnecting to see if there is an improvement.
