The ACT light on TP LINK does not light up, what is the reason?

TP-Link wireless router wireless status indicator does not light up Reason: The wireless function is not turned off; Loose network cable interface; The network cable is broken.

1. The wireless function is not turned off;

Browser input Log in to the settings background, open the wireless settings, and see if the wireless function is turned off, if it is off, check it to turn it on.

2. The network cable interface is loose.

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

3. The network cable is broken.

Replace the network cable connected to the corresponding interface for testing; Use another computer (network device) to connect to the interface and test whether it is normal. Use a network cable to directly connect the LAN port to the WAN port and check whether the indicator is normal.

act is the indicator light on the interface. ACT is a data traffic indicator, after networking, there is no ** or upload, it will generally only have an interval of flashing, when the traffic is large, the frequency of flashing will increase. It has nothing to do with connectivity.

Under normal circumstances, the cat will always turn on three lights Power Adsllink Lanlink (connected router), and the ACT light will flash when there is data reception, and will not always be on.

1) The ACT indicator does not light up.

If the computer is turned on at this time, then either the network card is corrupted or the slot of the network card is damaged. If the slot of the network card is damaged, the network card will not be able to be powered, and the "act" indicator will definitely not be on, then you only need to change the slot to solve the problem.

2) The ACT indicator is on, but the indicator indicating the working rate of the NIC is not lit.

The fault usually lies in the network cable, which may be the wrong wiring of the network cable or the fault of the network cable itself.

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.

TP-Link router is connected and set up not.

1. The bus of the broadband network is connected to the WAN port of the router, and the LAN port of the router is connected to the computer.

2. After starting the device, open the browser and enter it in the address bar to enter the wireless router settings interface. (If you can't get in, please look at the nameplate at the bottom of the router or the router instruction manual, the default settings of different models of routers are different.) ）

3. An account and password to log in to the router appear in the settings interface, enter the default account and password admin, or refer to the manual;

4. After successful login, select the interface of the setup wizard, which will automatically pop up by default;

5. After selecting the setup wizard, a window will pop up to explain that you can set the basic parameters of the router through the wizard, and click Next directly;

6. Set up step by step according to the setup wizard, select the Internet mode, usually ADSL users choose the first PPPoE, if you use other network service providers, select the following two according to the actual situation, if you don't know how to choose, directly select the first item to automatically select, convenient for novice operations, click next after selection;

7. Enter the account and password applied for from the network service provider, and go directly to the next step after the input is completed;

8. Set the wifi password, try to make the alphanumeric combination more complicated, and it is not easy to be rubbed off the network.

9. After entering correctly, it will prompt whether to restart the router, select Yes to confirm the restart of the router, and you can access the Internet normally after restarting the router.

In the power-on state, use a toothpick to press the factory reset button behind the "cat", if it still doesn't work, then please check:

1.**Whether the twisted pair is connected (you can take the **machine to try, if you can play, then the next step).

2.**Whether the twisted pair has good contact with the cat.

3.Check whether the two ends of the Category 5 cable (i.e. network cable) are in good contact (the inspection method can be as described in 5).

4.Check whether the Category 5 cable is damaged or a certain line is not open (the inspection method can be as described in 5).

5.Turn on the cat and turn it on, check the 2 indicators (orange light and green light) next to the network cable interface of the motherboard, if the link is normal, then one of these 2 lights must be on. And the other light flashes sometimes.

If you check the 2 lamp according to 5 as mentioned above, it can be confirmed that it must be a line problem or the network card or cat is damaged (if it is directly connected to the motherboard, then the network card cannot be damaged. If damaged. The motherboard will alarm and disable the system from booting).

If 2 lights are on, then please check that all the other lights on your cat are also on sometimes.

If it is bright, then you can confirm that it is.

1.The data storage chip inside the cat is lost.

2.The amplifier circuit is damaged.

If it doesn't light up. Then it is certain that it is.

1.The cat is not connected to the outside (even if it can be connected, it is likely that there is a problem with the cat's twisted pair interface, resulting in poor contact, or the internal connection of the cat is broken or short-circuited).

2.The cat's self-oscillator circuit control chip TL494 is damaged.

ACT indicator.

The computer's wideband ACT indicator does not light up may be caused by the following reasons:

If the computer is not connected to the broadband normally, it is recommended to check the connection environment, disconnect and reconnect to try again.

If the network cable connecting the computer to the broadband is damaged, it is recommended to check the network cable and replace it with a new network cable.

If there is a problem with the network card and the broadband indicator does not light up, check whether the network card is in arrears and the network card is shut down, and then pay the fee.

If the broadband is damaged, it is recommended to bring the broadband router to a computer repair shop for repair.

Restart the cat and then reinsert the cable to see what it is.

The LAN light indicates the connection status between the cat and your computer, and the normal state is always on. If it doesn't light up, it means that there is a problem with the physical connection, generally there is a problem with the network cable, and then the computer network card (for example, it is broken, the driver is not installed, the network card is disabled), and then the cat is broken, and the ACT flashes when there is data transmission, and the LAN is not lit, it definitely does not flash. The fastest detection method, take your own network cable, cat, go to a friend's computer to try :

1. Your network cable, your cat, and your friend's computer, so that the side is connected, if the lan is bright, it means that there is a problem with your computer network card. 2. Use a friend's network cable, your cat, and your friend's computer, so that the side is connected, if it is not bright, the cat is broken. 3. Use a friend's network cable, your cat, and a friend's computer, so that the side is connected, and it is lit, which means that your network cable is broken.

The Link Act indicator on the switch indicates whether the line is connected or active. Usually the link act indicator is used to see if the line is active or unobstructed. Under normal circumstances, if the line is unblocked, the indicator light will be on; If there is data transfer, the indicator light flashes.

The basic functions of the switch include the following:

1. Like a hub, the switch provides a large number of ports for cable connection, so that it is good to use star topology cabling.

2. Like repeaters, hubs and bridges, when it is framed, the switch will regenerate an undistorted square electrical signal.

3. Like bridges, switches use the same ** or filtering logic on each port.

4. Like a bridge, the switch divides the LAN into multiple conflict domains, and each conflict domain has an independent broadband, thus greatly improving the bandwidth of the LAN.

5. In addition to the functions of bridges, hubs, and repeaters, switches also provide more advanced features such as virtual local area networks (VLANs) and higher performance.
