Code of the most common router lights

- Internet: This is where we enter the realm of your connection. Labeled "Internet" or "Network", this light indicates that the router is receiving a signal from outside, whether fiber, ADSL or another type. If it is on, there is a line. If not, Houston, we have a problem.
- WLAN / WiFi: This crucial light indicates that your home or office WiFi network is up and running. It doesn't necessarily mean that devices are connected, just that the network is active. On some routers, this light only turns on when at least one device is connected. Additionally, the flashing of this light can give you an idea of the traffic on the internal network.
- LAN1, LAN2, etc.: These lights correspond to the router's physical Ethernet ports, where you can connect wired devices. Each light will light and flash based on the data traffic of the device connected to that specific port.
- PHONE/Tel: If your router has a port to connect a phone, you will have a light labeled "PHONE", "TEL" or with a phone icon. It will light up to indicate that the port is operational and running smoothly.
- USB: If your router has a USB port, this light will turn on when a device is connected, such as a printer, a hard drive or a pendrive. It does not usually flash depending on data traffic.
- WPS: This light indicates that the router's WPS function is active, allowing you to connect devices without entering the password. It is activated by pressing the WPS button and usually turns off after a minute. If it remains on for too long, it is worth checking the security settings.

In general, the lights come on in bright yellow or green color to indicate normal operation. However, colors can also signal problems:
- Without light: The function is off, either because the router is not connected, there is no Internet signal, or there are no network cables plugged in.
- Bright yellow or green light: Everything works correctly. Flashes indicate activity.
