What is the situation that the telecom broadband cat has three lights, but the network A in the midd

Hello: It may be caused by a problem with the line or modem, please check whether the modem is normal: generally the power light, synchronization light and network card light are always on, if it is normal, it is recommended that you turn off the modem and the computer for five minutes and then restart.

If the synchronization light, adsl dsl, adsl-link status, wlk, etc. are flashing or not bright, please check whether the wiring is loose; If the LAN 1-4 Ethernet Lan-Link PC LLL does not light up, check whether the connection between the NIC and the modem is normal and whether the network cable is loose.

I hope I have been helpful to you, and if you have any questions, please feel free to continue to consult us.

According to your description, there are generally four indicators for broadband modems, power power supply light, link** line connection indicator, data network packet sending light, and WLAN is the network port connection indicator. Under normal circumstances, there are these four, there are also 6 lights, basically these indicators need to be on under the normal operation of the network, according to the meaning of the indicators, you should understand that there is a problem. P lamp electric, W lamp connected to computer, L lamp** line lamp, D data lamp.

Generally, there is a situation that the L and D lights are not lit, and the basic prompt of connecting broadband is that the 678 remote computer does not respond, so you can call 10000 for repair.

If you need to check the bill and pay the phone bill, please log in to the online business hall of Anhui Telecom. Have a great day!

Hope mine is helpful to you and can get yours!

The reason why the broadband cat has only one power light on:

1. The back line is not plugged in, in this case, please check whether the back connecting lines are plugged in, whether the line itself is intact, whether the crystal plug is connected reliably, and whether the connector is intact.

2. The network card of the computer is faulty. Check whether the NIC driver is installed, whether the NIC itself is damaged, and whether the NIC is firmly inserted. If the NIC is damaged, replace it.

3. The broadband modem itself is faulty. In this case, you need to send the cat for repair, or change the cat.

The first is a power lamp, the second is a fiber optic lamp, and the third is a broadband lamp.

What do the lights of the fiber optic cat mean:

First, first of all, the first light on the broadband cat, written on the English letter power, this lamp represents the cat's power supply, it is always bright to show that the cat has been normal only sleepy power, which is the premise of ensuring the normal operation of the cat. If this light does not turn on, it means that the cat's power supply is broken, or simply the cat is broken.

Second, the second light is close to the power of the lamp, English is link, you must look carefully, the letter under the link is adsl, this light represents whether the network is connected, its normal working state is always on, that is, it has been on, indicating that the network is smooth. If you keep flashing, there are 3 possible situations:

1. The adsl line fell off or was not plugged in tightly, and the solution was to plug it in or plug it in tightly.

2. If the broadband is in arrears, the solution is to pay the broadband fee.

3. If the network operator fails, you need to check with the local operator. This is generally rare.

Third, let's talk about the second link first, the English below it is lan, this light is a local connection light, it is always bright when it is working normally, and under normal circumstances, its color is red, yes, it is red, it pants mountain is changed to a signal light, it only has two states, 1 is always on, 2 is not bright, when it is always on, it means that it is working normally, and when it is not lit, it means that the connection line is not plugged in or the connection line is broken, and the line needs to be changed.

Fourth, finally, let's talk about the remaining two ACT lights, these two are data indicators.

There are three types of normal working states of the data indicator, 1: not on, indicating that there is no data transmission, that is, no one is on the Internet.

2: Flashing, indicating that you are surfing the Internet.

In addition, if a wireless router is installed at home, the broadband cat at this time has another function, to detect whether someone is rubbing the network, when not using the network, to see the two ACT lights, whether it has been flashing, if it has been flashing at a high frequency, it is likely to be rubbed against the network, and the wireless password needs to be changed at this time. <>

Hello: This situation is most likely that there is a problem with your cat, and it is recommended that you can change the mess with a buried cat for testing. If there are still problems, you can call 10000 for repair.

At present, the indicator light judges that if it is a fiber optic modem dial-up and the router dynamically surfs the Internet, the reason for the network disconnection may be the incorrect configuration of the fiber optic modem data, or the broadband service Sakura server on the side of the telecom company.

The problem does not rule out that the fiber optic cat is broken; If it is a fiber optic modem bridging, the router dials up the Internet.

In addition to the above reasons, there may also be router Internet account passwords, Internet access methods, Internet configuration errors, network cable problems, etc.

The power light is on, the optical fiber light is on, the optical fiber is on, the wireless light is on, the wireless light is on means that the wireless part of the optical fiber cat is working normally, and the optical signal light will not be on in normal use.

If the landlord doesn't know much about this aspect, I suggest that you call the operator ** to report for repair during working hours tomorrow and let the maintenance master come to take a look.

You see that the wifi signal on your mobile phone looks like a full signal, it is indeed not connected to the network, and the wifi signal is strong and may not be able to access the Internet, which is a very big "deception" to people.

Because you are accessing the signal from your router, if the network from this router to the telecom is not connected at all or the router is dead, this signal has no effect at all.

You can first check your home router to see if there is a red indicator light from the optical modem from the telecom equipment, that is, whether the indicator light of "optical signal" is red, if it lights up red, it is simply the optical fiber of the telecom optical distribution box to your home is broken, and you can only ask telecom maintenance personnel to deal with it.

If this "light signal" indicator is a normal green light, you can power off the router and turn it on again, and the general problem will be solved.

The optical signal light of the optical modem lights up red, indicating that the optical modem cannot receive the optical signal alarm, indicating that there is a problem with the optical fiber line.
