Router LEDs meaning the wireless router led plot

With the popularity of smartphones, wireless routers are already in the tens of thousands of households, while smartphones, tablets and laptops and other wireless devices Wi-Fi internet is mainly provided by wireless router wireless network. However, sometimes there will be some network problems, resulting in a computer or smart phone device this time we can usually use the router led to determine the status of the router, which can better find some of the cause of the failure.

First, let's take a look at the router's interface diagram. The general wireless router mainly includes antennas, 4 LAN ports, WLAN ports, power connectors, reset buttons, etc., as shown in the figure below.

Router interface meaning diagram

Where the antenna is mainly used to send WiFi wireless network, LAN port is mainly used to connect the computer, WLAN port used to connect the external network cable. Simple understanding, wireless router interface, the following is attached to a more classic wireless router and the cat, network cable Connection diagram.

Router, cat, computer and cable Connection diagram

If the wireless router will not be able to surf the internet, first check the router, CAT, computer and network cable Connection is normal, if the router setup is not a problem, the following we can through the router when the light meaning to determine the router's failure.

Wireless router led diagram

The router LEDs can usually be divided into 4 categories, namely the power indicator, SYS system indicator, LAN indicator, WAN led, and these four LEDs have the following meanings:

Power indicator

This indicator light is the power supply of the power supply, the normal work must be always bright, not bright indicates that the power is not plugged in or the router is broken.

SYS System indicator

This SYS system indicator is the working status indicator of the router, the flashing indicates normal, if the SYS system LED is not lit or will light, but does not blink, then basically the router has a problem.

LAN indicator

LAN interface is connected to the computer, if the network cable will connect this interface and the computer's network card interface, after turning on the computer, the LAN light will be light, if not illuminated the interface or network cable problems. The interface problem may be the router interface or the computer NIC interface problem.

WAN Indicator

The WAN LEDs show the external wideband line signal LEDs. Solid indicates that the port is connected to the front cat properly. When there is data transmission, such as the device in the Internet, the normal situation will be transmitted data, the transmission process, the WLAN port will continue to blink.

If the WAN led is not lit, it indicates that the cat or external network cable has a problem, if the WAN LED lights but does not blink, and mobile phones, computers can not surf the internet, then the main network is a problem, you may telephone consulting network service providers, to confirm whether the broadband line failure.

With the popularity of routers, many netizens now have basic wireless routers, if the future encounter routers can not access the Internet, to remember to check the router instructions Oh, by analyzing the meaning of the router lights, you can roughly determine whether the router, network cable or networking equipment problems.
