In this article, we’ll delve into the possible reasons behind the WAN blinking red and provide you with troubleshooting steps to resolve the issue.
Understanding the WAN Light
Before we dive into the reasons behind the WAN blinking red, let’s first understand what the WAN light represents. WAN stands for Wide Area Network, which refers to the connection between your local network and the internet. The WAN light on your router indicates the status of this connection. Typically, the WAN light is steady green or blue when the connection is stable and working properly. However, when the light starts blinking red, it’s a sign that something’s amiss.
Possible Reasons for WAN Blinking Red
There are several reasons why the WAN light on your router might be blinking red. Here are some of the most common causes:
