The broadband connection is not connected, and the ADSL is not always on

.The most blocky approach. Call 10000 to complain. Someone will come and fix it soon.

Since the cat has been changed, it is not the cat's problem, and since it is not the cat's problem, then there is only the problem of the line and the separator.

Make sure that the socket of the separator is plugged in correctly. modem corresponds to the cat, phone corresponds to the **machine, lind corresponds to the **line, if it's not right, the line will be broken when the intercom is mentioned.

If the separator is fine, it's a wiring problem.

You can find a maintenance person to change the line for you.

You check the crystal head of the network cable to see if the contact is not good. When the connection is disconnected again, you can turn off the cat for 5 minutes and then restart it. You can also try to insert a toothpick into the reset hole behind the cat for seven or eight seconds to let it reset!

Finally, I remind you to check whether the cat has bad heat dissipation, because it will also be overheated for a long time!

There are several possible problems with the port in the 1 computer room that cause the disconnection.

2 cats cause.

3 Causes of voice separators.

4. Poor contact of the crystal head.

Problems with the splitter to the pole bus line.

If it's not the problem they say, contact the maintenance personnel to change the cable wiring, sometimes there is a problem with the cable line, you win the lottery, and you happen to use the pair of cable cables in question.

The "Error 651" displayed on broadband Internet access is mainly caused by the failure to connect the user's terminal computer with the Netcom central office equipment, which is generally divided into five situations: "network cable failure", "modem failure", "network card failure", "modem itself setting", and "network operator problem". Here's how to deal with such cases:

1. Please replug the network cable and ** cable and restart the modem test;

2. Please disable the local connection first, and then enable the local connection;

3. Please reinstall the NIC driver;

4. If you use a router, please remove it, and dial test it on a single computer.

Summary. Analysis of the reasons why the broadband Internet light does not light up is as follows: The solutions for the broadband light not on the router are as follows: 1. Call the operator's customer service ** to check whether there is a problem with the external network; 2. Re-plug the network cable once, the network cable connected by the cat is connected to the WAN port of the wireless router, and the computer is connected to any LAN port of the wireless router; 3. Turn off the cat and the wireless router and turn them on, and observe whether they are restored later; 4. If none of the above methods are feasible, you need to set up the wireless router again.

The reasons for the broadband Internet light not lighting are analyzed as follows: The solutions to the broadband lights not lighting on the road are as follows: 1. Call the operator's customer service ** to check whether there is a problem with the external network; 2. Re-plug the network cable once, the network cable connected by the cat is connected to the WAN port of the wireless router, and the computer is connected to any LAN port of the wireless router; 3. Turn off the cat and the wireless router and turn them on, and then observe whether the bad file is restored; 4. If none of the above methods are feasible, you need to set up the wireless router again.

First, the signal indicator is not lit, the signal indicator is not lit, it should mean that there is no signal for transmission, but it is certain that the lines are normal, use the replacement method to change the network cable connected to the computer to another computer to try or use a tester to check whether there is signal transmission. Signaling is a problem with the local network card, and it has been proven in actual work experience that the network card causes no information transmission is a relatively common router failure. First of all, check whether the network card is installed normally, whether the IP setting is wrong, you can try to ping the IP address of the machine, if it can be ping, it means that the network card is not too problematic.

If not, you can try to reinstall the NIC driver. For some network cards that use integrated network cards or network cards of low quality, it is easy to appear unstable phenomenon, that is, all the settings are correct, but the network is not connected, the network card can be disabled, and then re-enabled, it will also have an unexpected effect.

Second, the connection indicator light is not lit to observe the network card behind the RJ45 side of the side of the two indicators, they are the connection status indicator and the signal transmission indicator, in the normal state of the connection status indicator is green and always on, the signal indicator is red, normal should keep flashing. If you find that the connection light, i.e., the green light is not on, then it means that there is a router failure in the connection between the NIC connecting to the hub or the switch. This can be done with a tester for segmentation exclusion if the switch to the NIC is interconnected by multiple modules.

You can replug the network cable again, or check whether the network cable is broken or broken.

Generally, the router will display the power light, broadband signal light and wifi signal light when working normally, it must be always on during normal operation, if it is not lit, it may be not energized, or the power supply, the router is damaged, check the socket and power connector in turn. If it's just that the power light doesn't light up but the router works normally, it may be that the power LED bead is faulty.

Broadband considerations.

It is necessary to pay attention to determine whether there is still space in the trunking to put the network cable, if not, you have to find another way.

The threading pipe is now no longer used for steel wires, which are easy to damage the wires and pipes in the trunking. There is a special material made of plastic that is similar to steel wire, which is both hard and can be turned without damaging the conduit. Find a professional person who does pipeline construction can solve it.

If none of the above works, then follow the direction of the trunking, chisel a groove out of the wall, and after installing the trunking and line, wipe the wall.

If the indicator of the router does not turn on after connecting the computer, router, or modem according to the normal application topology, the problem may be related to poor network cable contact, fault, port fault, etc.

1. Check whether the WAN port is wired, and check whether the cat connected to the WAN port is powered (the network cable does not need to be checked when entering the home).

2. Confirm whether the WAN port connection line is loose. For some broadband lines, the indicator light does not light up due to the long network cable or poor network cable quality, and the router and line are not successfully adapted, so you can try to replace the network cable with better quality.

The LAN port indicator light is not on:

1. Check whether the network cable between the computer and the router is loose, causing poor contact, please plug and unplug the network cable again.

2. Try to change the computer to another LAN port of the router for comparison and testing.

3. Use a network cable to connect any 2 LAN ports of the router to see if the indicator display is normal.

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

5. If the indicator light is not on, make sure that the network cable can be connected to other devices and can be used normally, it may be a faulty router port.

Hello, the indicator light is not lit, you see if the broadband is normal, whether you can connect to the network normally, if you can't connect to the network normally, it should be a broadband failure, directly call the telecom customer service to report the fault can be 48 hours a day, there are staff to troubleshoot, if the indicator light is not on, the network is normal, then it should be the indicator light is faulty, but do not delay the normal use of the network.

Each indicator light of the cat contains power--power LAN -—— light means that the cat to the computer line is no problem, act--- there is data transmission then flash, that is, it will flash adsl when connected to the Internet——— this is very important, connect to the telecom equipment to light up, do not light up on the telecom**.

This is an optical modem,After resetting, you need to set broadband dial-up information to dial up the Internet normally,Change the wireless password can be modified directly in the web interface。 There is the login account name and password in the back nameplate. If you don't know the settings, you need to call your broadband provider and let the master come to set it up for you.

If it is a China Unicom broadband product, if the light modem light at home does not turn on, it may be caused by the following reasons:

1. Restart the modem and router and try again.

2. Check whether the optical fiber at home and the network cable connection connecting the optical modem, router and computer at home are normal;

3. After restarting the modem and router, check whether the device does not light up or lights up red, if the light signal light does not light up or turns red, it means that there is a line problem, and you need to call the local Unicom manual customer service to report the fault repair.

The reasons why the broadband does not light up are: the wireless transmission is turned off when the router is set, the components inside the wireless router are damaged, the router is not powered on, the plug-in board is not powered on, etc.

1. The wireless transmission is turned off when the router is set.

This will lead to the phenomenon that the wifi broadband light does not light up, and the router can be reset, so that the problem can be solved. Remorse.

2. The internal components of the wireless router are damaged.

This will lead to the phenomenon that the wifi broadband light is not lit, you can change to a new router for setting, and after setting it up, you can solve the problem that the wifi broadband light is not lit.

3. The router is not powered on.

There will be a phenomenon that the wifi broadband light does not light up, you can plug in the power supply of the router, so that the problem can be solved.

4. The plug-in board is not energized.

The plug-in board can be checked, and if there is no electricity, a power-on plug-in board can be replaced, so that the problem of wifi broadband light not lighting can be solved.

Broadband does not light up solution:

1. If you can access the Internet, it means that the indicator light of the WAN port is broken, and you can ignore it.

2. If the other indicators are still on, please check the network cable and crystal head between your cat and the router to rule out poor contact.

3. If you can't access the Internet, you can directly connect the computer through the cat with broadband, if you can get on, it is the front elevator of the routing bureau is broken, you can try to change the road mail.

4. If you can't access the Internet with broadband, it may be that the cat is broken or the network is faulty, and you can find a network maintenance worker to help you solve it. <>

If the power light is not on, check the power supply part of the router, and if possible, you can replace the power supply to check it. If the broadband indicator is off, check to see if the network cable or interface is faulty, or if the broadband operator is faulty. If it is a wifi signal light, you can check whether the wifi signal is turned off.

Introduction:

If the indicator cluster of the wifi network fails to light up, it may be that the wifi wireless signal is turned off, it is recommended to check whether the router has a hardware wireless switch button to click on, or enter the router's management page to check whether the wifi signal is turned off, and turn it on again to solve the problem.

Some routers also have a dry sys system indicator, this is the working status indicator of the router, flashing means normal, if the sys system indicator is not lit to cut off all the power, turn the router back on, and it still does not light up after restarting, it is recommended to press and hold the reset button in the route infiltration modifier, wait for the router to reset, and then reset the router again.

The reasons and solutions for broadband Internet access lights not to light up are as follows:

1. First of all, you need to confirm whether you can still access the Internet, if you can still access the Internet, it means that the broadband indicator is broken, don't worry too much.

2. If you can't access the Internet, and other indicators are still on, you need to check whether there is a problem with the network cable and crystal head between the cat and the router, and you can plug and unplug the network cable again to eliminate the problem of poor contact.

3. Turn off the cat and the router and restart it to eliminate the fault caused by too much data cache or abnormal finger flush heating.

4. Secondly, disconnect the router and connect the computer to the cat by wire, if the computer can access the Internet normally, it means that it is a problem with the router and needs to be replaced with a fun router; If the computer can't access the Internet normally, it may be that the cat is broken or the network itself is faulty, you can call the operator's customer service** and seek a network maintenance worker to solve it.

Broadband connection:

Broadband connection is a relative way of describing the continuation of the number or the electronic line containing or being able to handle a wide range of frequencies at the same time, and the larger the frequency range, that is, the higher the bandwidth, the relatively higher the transmission of data. The upper limit of the dial-up Internet speed is 56kbps, and the lower than 56kbps is called the narrow tan band, and the above is called broadband. For home users, it means that the transmission rate exceeds 1m, which can meet the needs of a large amount of information transmission such as voice and image.

Including fiber, XDSL (ADSL, HDSL), ISDN, etc. <>

There is no fork electricity, or there is no fork good, check it repeatedly.
