The Link light of the router, which will be on for a while and will not be on for a while What s goi

If the router indicator light is not on, there are generally three possibilities:

1. Router WAN port connection problem;

2. The hardware equipment is damaged;

3. Other reasons.

1. Router WAN port connection problem;

1) The WAN port of the wireless router needs to be connected with a network cable and a modem, optical modem, and broadband home network cable, and if the connection is wrong, there will be problems.

2) There is a problem with the network cable used to connect the router to the device. If the network cable is directly connected to the computer and the device after the router is removed, the network cable is normal, and the network cable is not connected, the network cable is abnormal and needs to be replaced.

2. The hardware equipment is damaged;

1) The wireless router is damaged. If there is no problem with the cat, optical modem, and home network cable, but the router is damaged, the light will not turn on, and you need to replace the router with a new one.

2) The cat, optical modem, or broadband home network cable is damaged. If you can't access the Internet, it means that there may be damage, resulting in the light not turning on.

3. Other reasons.

One of the common reasons is that the network cable is too long, which causes the signal to be unstable, so the router cannot detect the signal and the indicator light is not on. The principle is that the theoretical transmission distance of ordinary network cables is about 100 meters. Beyond this distance, the network becomes unstable and various problems arise.

About the lights of the router:

Normally, the link and power lights are solid on, and the data and act are flashing.

Generally, the problem is not flickering. A normal connection but no flickering means there's no data, so it's possible that there's a setup issue or hardware damage. However, if it is a wireless router with modem, the situation is relatively complicated, and the situation of the lamp is different for different brands.

What happens when the TP-Link wireless router status light keeps flashing? Everything works fine with the internet.

sys, lan, as long as the power is turned on, the sys light will be on. 2. After the router and the cat are connected, the WAN light will be on. 3. The LAN light corresponds to the interface, and the light will be on which port the network cable is plugged into.

TP-Link is a national high-tech enterprise in the process of rapid development and internationalization, and its manufacturing equipment is very powerful in performance and function, so do you know how to solve the problem that the TP Link router light is not lit? The following is some relevant information I have compiled about TP Link router lights not lighting up for your reference.

TP Link Router Light Doesn't Light Up Solution:

Indicator location map.

Note: The indicator of some routers is in the upper left corner of the network cable interface.

If the indicator of the TP Link router is not lit, perform the following steps:

1. Check whether the network cable interface connected to the corresponding interface is loose.

2. Replace the network cable connected to the corresponding interface for testing.

3. Replace other interfaces and test whether they are normal.

4. Use another computer (network device) to connect to the interface and test whether it is normal.

5. Use the network cable to connect the LAN port and the WAN port directly, and test whether the indicator is normal. As shown below:

If the indicator of the corresponding interface is still abnormal after passing the above test, it can be judged that the interface hardware is faulty.

Solution for TP Link Router WAN Port Indicator Not Lighting Up:

1. Check whether the cat connected to the WAN port is powered by power. (If the network cable enters the home, there is no need to check).

2. Confirm that the WAN port connection line is not loose. If the indicator light does not light up due to the long network cable or poor quality of the network cable, or the unsuccessful adaptation of the router and line, you can try to replace the network cable with better quality and the line sequence is standard 568A 568B.

3. Please check that the specifications of the power adapter match. Check whether the specifications of the power adapter are consistent with the power specifications of the tin mark on the router backplane, if not, the router may not work properly.

4. The indicator light of the front-end network cable connection WAN port is not lit, and the LAN port connection is normal. You can use a network cable with good quality and the line sequence is standard 568A 568B to connect the LAN port and the WAN port directly, if the WAN port indicator is still not lit, it may be that the interface is damaged, you can contact the office for testing.

Note: After the wireless bridging function is enabled on some cloud routers, the WAN port is disabled, so when any device is connected to the WAN port, the corresponding indicator light is not on, please make sure that the wireless bridging function of the cloud router is not enabled.

Solution to TP Link Router LAN Port Indicator Not Lighting Up:

1. Please check whether the network cable between the computer and the router is loose and the contact is not good, please plug and unplug the network cable again.

2. Try to replace the computer with another LAN port of the router for comparison test;

3. Use a network cable to connect any two LAN ports of the router to see if the indicator display is normal.

If it is normal, you can troubleshoot the router port first, and the computer is connected to the corresponding LAN port, and the indicator light is not on, it is recommended to replace the network cable.

If the indicator light is not on, it may be a faulty router port when connecting to other devices to ensure that the network cable can be used normally.

The router's lights stay on.

1. The wireless router system status indicator has no effect if it is always on, and the manual says that the normal state is always on the reason: flashing indicates that there is data transmission. Second, the wireless router has three kinds of lights:

sys,lan,as long as the power is turned on, the sys light will be on2、After the router and the cat are connected, the WAN light will be on. 3. The LAN light corresponds to the interface, and the light will be on which port the network cable is plugged into. 1. A wireless router is a router used for users to access the Internet and has a wireless coverage function.

2. The wireless router can be regarded as a device that sends the broadband network signal from the wall at home to the nearby wireless network devices (laptops, mobile phones that support wifi, tablets and all devices with wifi function) through the antenna. 3. The popular wireless routers on the market generally support four access modes: dedicated line XDSL cable, dynamic XDSL and PPTP, and it also has some other network management functions, such as DHCP service, NAT firewall, MAC address filtering, dynamic domain name and other functions. 4. Popular wireless routers on the market can generally only support the use of 15-20 devices at the same time.

5. The signal range of general wireless routers is 50 meters, and now some wireless routers have a signal range of 300 meters. First, whether the red light of the router is definitely a fault or it may just be a loose connector or arrears, so you should first make some attempts yourself, if you are sure that it is not caused by these basic problems, you can call customer service**, and ask the other party to send some professional personnel to overhaul. Second, the red light of the router wants to improve what are some methods It is recommended not to dial ** immediately after encountering it, you can reconnect the network cable first, if you connect it again, there is still no way to work normally, this is likely to be because of the fault problem, at this time it is more reasonable to choose to dial**.

3. Choose to call someone to repair, how long does it take If the red light of the router keeps beating, it is determined that it is caused by a fault, you can choose to find someone to repair, generally within 5 or 6 hours will come to the door to operate, and the problem can be solved within the same day. When the wireless router signal light is working properly: I hope it can help you.

If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

If the router light does not blink there is no data exchange, there is data exchange, and the indicator light flashes automatically. It is possible that the connection of your router is faulty, resulting in no data exchange and no flashing light.

When the wireless router signal light is working properly:

The WAN port light flashes.

If the router is connected to the computer via a network cable, the corresponding LAN port light flashes.

The wireless WLAN light flashes.

The power light is always on.

The sys system running light is flashing.

When the wireless signal light is not working properly:

The lights at the entrance of the wan are off. Check the connection of the router to the modem.

The LAN exit light goes out. Check the connection of the router to the computer.

The wireless WLAN light is off. Whether the WLAN is disabled or abnormal.

The power light goes off. Check that the power cord is not loose.

The SYS system running light is off. If the router fails, consider resetting or replacing the wireless router.

There are three possible reasons why the lights on your wireless router won't turn on:

1. The connection indicator light means that the green light is not on, which means that the connection between the network card and the hub or switch has a router failure.

Segmentation exclusion can be done using a tester, and if the switch to the NIC is interconnected by multiple modules, then a dichotomy can be used for quick positioning.

2. Under normal circumstances, most of the router failures occur because the network cable is not firmly connected, and the inferior crystal head is used, and most of the fault points are problems at both ends of the connection.

For example, the connector at the port of the switch and the network card connected to the computer can be easily solved with the help of the tester.

3. Then the red light of the signal indicator does not light up, which means that the line is fine, and the main problem is caused by the network card.

In such a situation, you can check whether the NIC installation is normal, whether the IP setting is incorrect, or you can try to reinstall the NIC driver to solve the problem. Harvest.

It is normal for the router to flash, if the IP cannot be obtained, it is estimated that the packets in the route are blocked. We recommend that you restart the route, that is, replug and unplug it.

If it still doesn't work, consider factory resetting it.

If the router indicator light is not on, there are generally three possibilities: 1. Router WAN port connection problem; 2. The hardware equipment is damaged; 3. Other reasons. 1. Router WAN port connection problem (1) The WAN port of the wireless router needs to be connected with a network cable and a cat, optical modem, and broadband home network cable, and if the connection is wrong, there will be problems.

2) There is a problem with the network cable used to connect the router to the device.
