Hello, the LAN port indicator light flashes, indicating that there is data exchange. This flicker is normal.
1. power indicator
This indicator lamp is an indicator lamp that connects the power supply to the power supply. It must be turned on at all times during normal work. If it doesn't light up, it means that the power supply is not plugged in or the router is broken.
2.SYS system indicator light
The SYS system indicator light is the working status indicator light of the router, and flashing indicates normal. If the SYS system indicator doesn't light up or will light up, but it doesn't flash, then basically there is something wrong with the router.
3. Landing indicator light
The LAN interface is connected to the computer. If this interface is connected to the network card interface of the computer with a network cable, the LAN indicator will light up after the computer is turned on. If it doesn't light up, there is something wrong with the interface or network cable. The interface problem may be a router interface or a computer network card interface problem.
4. WAN indicator light
The WAN indicator shows the external broadband line signal indicator. On indicates that the port is normally connected to the front-end cat. When there is data transmission, such as when the device is online, the data will be transmitted normally, and the WLAN port will keep flashing during the transmission.
If the WAN indicator does not light up, there is something wrong with the cat or the external network cable. If the WAN indicator light is on but not flashing, the mobile phone computer can't access the Internet, mainly because of the network cable. You can call the network service provider to confirm whether the broadband line is out of order.
What does the router light flashing mean?
1. If the LOS light turns red or flashes, it is usually caused by the following conditions:
1. There is something wrong with the optical interface of the optical cat, which needs to be replaced.
2. The optical cat connector of indoor tail fiber connection is loose.
3. Some indoor optical fibers are too bent.
4. The outdoor optical fiber is broken or the optical port of the equipment in the computer room is faulty.
5. The router is out of order, which makes the router unable to convert optical fiber signals normally.
6. Failure of optical fiber pigtail leads to abnormal transmission of optical signals.
7. External network failure leads to local network failure.
Second, the solution:
1, the light cat needs to be replaced;
2. The connector is loose and can be restored after being plugged in;
3. Excessive bending of optical fiber will affect the total reflection transmission of optical signals in optical fiber, as long as the optical fiber is straightened;
4. If the outdoor optical fiber is broken or the optical port of the equipment in the computer room is faulty, you need to contact the staff to troubleshoot.
5. Check whether the optical fiber line (usually yellow line) behind the optical fiber cat is folded or squeezed, and straighten the line with a little force to see if the red light situation returns to normal.
6. Restart the broadband port. Turn off the power of the optical fiber cat and the router, wait for 5- 10 minutes to restart, and see if the situation is restored.
Extended data
The meaning of light on a light cat:
1. First of all, the equipment must have a power supply, so the power light must be on for a long time, and then the "network" sign is the signal light of telecommunications. If it is on for a long time, it means that the telecommunication signal is normal; if it flashes, or the light signal flashes red, it means that the signal is abnormal.
2. When the optical fiber head breaks, use the optical signal indicator. As long as the red light flashes, the optical fiber must be broken.
3. The broadband will flash only after you connect to the Internet and show that there is data online. If you have a telephone voice light installed in your home, it will light up.
4. "Network interface 1" means that the light cat lights up when the connection to your computer is normal.

The red light on the router keeps flashing, so I can't get on the Internet. There are the following situations:
1. There is something wrong with the optical interface of the optical cat, and the optical cat needs to be replaced;
2. The optical cat connector connected with the indoor tail fiber is loose, and it can be restored by inserting the connector;
3. Some indoor optical fibers are too bent. Excessive bending of optical fiber will affect the total reflection transmission of optical signals in optical fiber, as long as the optical fiber is straightened;
4. If the outdoor optical fiber breaks or the optical port of the equipment in the computer room fails, you need to contact Unicom staff to troubleshoot.
Routers can also be called gateway devices. Router is the network layer relay and layer 3 relay task completed in OSI/RM. It stores and forwards data packets between different networks, and its main purpose is to separate networks with different logics. Data is transmitted from one subnet to another and can be processed by the routing function of the router. In network communication, routers have the functions of judging network addresses and selecting IP paths. They can build flexible link systems in various network environments and link subnets through different data grouping and media access methods. In operation, the router only accepts the information sent by the source station or other related routers, and is an interconnection device based on the network layer.
What does it mean that the router WIFI is flashing all the time?
The flash of the wireless router indicates that the network connection is normal, which is normal.
In the case of connecting a computer through a wireless router with only a network cable, three lights will flash.
When the WAN port light is on, the external network is normal; when the LAN port light corresponding to the connecting cable flashes, the equipment is normally connected to the network; when the other light flashes, the wireless network is normal.
A router is a device that connects a local area network and a wide area network in the Internet. It will automatically select and set the route according to the channel conditions, and send signals in turn by the best path. Routers are the hub of the Internet and the "traffic police". At present, routers have been widely used in all walks of life, and products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet.
The main difference between routing and switch is that switching takes place at the second layer (data link layer) of OSI reference model, while routing takes place at the third layer, namely network layer. This difference determines that routers and switches need to use different control information when moving information, so they realize their respective functions in different ways.
Routers, also known as gateway devices, are used to connect multiple logically separated networks. The so-called logical network represents a single network or subnet. When data is transmitted from one subnet to another, it can be done through the routing function of the router. Therefore, the router has the function of judging the network address and selecting the IP path. It can establish flexible connection in multi-network interconnection environment, and can connect all kinds of subnets with completely different data grouping and media access methods. The router only accepts information from the source station or other routers, and belongs to an interconnected device in the network layer.
What do you mean the lights on the router are flashing?
Explanation of flashing router indicator light
The flashing light on the router indicates that there is data traffic and the computer is surfing the Internet. Continuous flashing or even frequent flashing means a lot of traffic, and none of them means that you are not surfing the Internet. ) To troubleshoot a router, start with the following steps:
1. The red expression is abnormal, and the green one is normal. It is recommended to check whether the router can access the Internet. If possible, it is recommended to restart the router to see if it is still red.
2. If yes, please restore the factory settings and reconfigure, or contact the official customer service to ask. Because different brands of routers have different color lights.
