What Is the Blinking Lights on the Back of Xfinity Router Mean

Before we start, it should be noted that there is no specific standard when it comes to router LEDs. Each manufacturer sets their own criteria for the flashing and color of the lights. However, they are simple and intuitive when it comes to interpreting them with some basic concepts.

Evolution of routers in terms of LEDs

The passage of time has affected the performance of our home routers. We almost always had the same number, which usually ranged from five to eight. The moment the router blinks, whether the LED is on or not, it transmits information to us. If you look at the first ADSL routers, they had the following metrics:

• One of "Power" or turning on the equipment.
• One for each Ethernet port, of which there were usually 4.
• The other is for Wi-Fi.
• One that has an ADSL / DSL connection.

A typical example from this era would be the Zyxel 660 HW-D1.

However, in recent years the situation has changed somewhat. Although we have about the same number of LEDs, the way of displaying has changed with the advent of new technologies. In this sense, for example, the solution might be to have one LED for all LAN ports. Thus, the user is not so saturated with so much information.

We must remember that new LEDs have been added over time, such as WPS, 2.4GHz Wi-Fi network, and 5GHz Wi-Fi network.

Therefore, a good starting point is to get close to our home router. So if we look at this LED, it usually has an icon or name that describes it … For example, Wi-Fi is called WLAN and energy is called Power.

How to interpret router LEDs

One way to get information about the state of our router is to look at LED color … They usually use two colors:

• Green means that everything is in order and working properly.
• Red means an error has occurred or there is a problem. In this case, it is a sign that we have a connection problem, in the LAN ports or where it points to us.

Another thing that we should watch if the router is blinking or not … In most cases, this is due to whether there is traffic on our local network or Wi-Fi. Thus, we can establish that:

• If the router is blinking, this usually indicates that there is traffic on our network and that some equipment is connected to us.
• If the LED on the router is on continuously, it means there are no devices connected.

This is true when the router is blinking, as sometimes they have solid LEDs. When the LEDs are not blinking, there may or may not be traffic on our network. … Some manufacturers keep them fixed because we have more and more devices connected, and they will be interrupted almost all the time.

As for the LED indicators that we usually find in our router and which can give us information, we have:

• Inclusions : If the router has power and is turned on, it will remain unchanged, usually green.
• LAN – If lit, it means that you are connecting the computer with an Ethernet network cable. If it is intermittent, it means that it is transmitting data, that is, it is assumed that it is not one of those that always remain fixed. Their number can be different: from one for each Ethernet port, one for all, and even none.
• Wi-Fi : If it works, it means the Wi-Fi network is activated. If it blinks, it means data is being transmitted, suggesting that it does not always remain the same. Their number can be different: from one for each Wi-Fi band or just to one. An example would be one 2.4 GHz Wi-Fi network and another 5 GHz Wi-Fi network.
• Internet / ADSL / xDSL / FTTH : If the LED is on continuously, it means that the connection is correct. If it is intermittent, data is transferred between the router and the network, provided that it is not the type that always remains the same. If it is red or off, it usually indicates a failed or failed internet connection.
• WPS : If you don't know, it is used to establish a connection without entering a password. If the LED is on continuously, it means that it is active. When it blinks, it transmits our Wi-Fi password to another device for configuration.
• Phone / Fon / DECT : If we have a phone connected to the router, this indicator will be on continuously. The LED can also blink when we are talking on the phone.

Now, if the router is blinking or has LEDs of a certain color, you can understand what this means. It is also recommended that you download your router manual to help you interpret the LEDs.

Configuring and managing the LEDs of the router

This option is not usually found in routers that ISPs typically use. The ones that offer this are usually networking hardware manufacturers who have more advanced firmware in their routers. So, apart from configuring the LEDs, they usually have a Wi-Fi time programmer, a section for home automation, another one for Mesh networking, and more. In short, they offer a lot more options besides superior performance. Here we take FRITZ! Router Box 7530 as an example:

One of the features of this router, besides the fact that we can control and configure its LEDs, is that we can highlight an LED that says: Info »For the task assigned to him. To do this, we need to enter the configuration of the router, go to " System , Buttons and Indicators »And select Info LED …

Here are the options that will allow us to select information about the LEDs:

As you can see, it is very diverse, we could use it to find out if we have an active Internet connection, if a USB device is connected, or if we have a message on our answering machine. On the other hand, if we go to the section Indicators (LEDs) we can control and customize their behavior.

This way, for example, we can control the brightness of the LED indicators. For example, if there is a router nearby and you are worried about the light intensity, you can adjust it to your liking. Also, it may happen that you have a router in the room and you may be disturbed by the LED indicator before bed. In this situation, or if you just don't want them to be on, you can turn off all the LEDs.

As you have already seen, thanks to the LED indicators of the router, we will be able to see in general terms what is happening on the local network, as well as when connected to the Internet. If you are using a router not purchased from your carrier, it is possible that you can control the LEDs to turn on and off, and even configure them to indicate different states.
