The computer keeps dropping What does it mean that the 4 lights on the cat are on?

It is most convenient to find a maintenance person, when the line is dropped, the light flashes, there is a problem with the line, or the cat is bad. If the PC light does not turn on, the network card may be defective, or there may be a problem with the network cable connected to the network card. Usually, the link indicator flashes rhythmically, indicating that the data is not synchronized and is trying to be synchronized, in this case, the line is often faulty.

First listen to whether there is any noise from the bus line that enters the house, and there is a noise: there is a problem with the line. Looking for a repair.

There is no noise bus to connect the cat to the bus to see if the signal can be synchronized. If it can, then there is a problem with the indoor wiring. It can't be that the cat is bad, and there is a problem with the telecommunications bureau.

Indoor line defect disposal method: the first step, please check the indoor ** line, if there is a joint on the line, you need to remove the oxide layer of the joint and tighten the line joint. Turn the modem back on, and if it is still out of sync, proceed to step 2.

The second step, the incoming plug of the voice data separator is directly plugged into the ** line interface of the modem, and the purpose of this is to eliminate the influence of the separator on data communication and re-turn on the modem power supply. If it is synchronized, it means that the separator is faulty or the line plug-in part is in poor contact. Poor contact users can use a knife to gently scrape the ** line crystal head contact to solve it.

If it doesn't work, try replacing the separator. If you still can't sync, proceed to step 3. The third step, remove all the parallel machine, the purpose of this is to eliminate the impact of the machine on data communication, if the synchronization, it means that there is an error in the parallel wiring, according to the correct scheme and connect the secondary machine.

In a word, ** have to go through the separator, ADSL or Modem to connect the cat, phone to **, Line to connect to the incoming line.

Look at whether the dropped line is PC and so on, and it should be a problem with the ** line. Cats are also possible, but cats are less likely. It is advisable to check the route. No, change the cat again. Or change the cat first and then check the line, because it is troublesome to check the line.

The indicator light of the computer's optical modem is always on: power light, optical fiber, optical signal light, broadband light, wireless light, **, network port.

The role of fiber optic cat lights:

1. Power lamp.

This lamp represents the cat's power supply, and it is always bright to indicate that the cat has been energized normally, 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.

2. Optical signal light.

This light represents whether the network is connected, and its normal working state is always on, that is, it is always on, indicating that the network is smooth.

3. Broadband lamp.

This light is a local connection light, which is always on when it is working normally, and its color is generally red.

4. **Lamp.

Steady light indicates that the operator's data has been provisioned, and the ** port can be used; When the light flashes, it means that ** is in use; If the light is off, the carrier has not enabled this port, and the modem cannot use port **.

5. Wireless lights.

Wireless signal, but this cat does not open the routing function by default, so most people can't use the wireless signal when they connect to it.

6. a network port lamp.

It is Internet access, and some broadband cats only have network ports 1 and 2.

The Link light is an indicator for the cat to connect with the central office DSLAM device, usually the Link light flashes rhythmically, indicating that the ADSL data link is trying to synchronize, and the link has not yet been connected. Under normal circumstances, there is a one-minute synchronization process after the ADSL cat is powered on, and the link light is always on after the synchronization is successful, and the link light of some brands and models of the cat has the function of data sending and receiving indicator, which will flash with the data transmission. After surfing the Internet, if the link light flashes rhythmically, it means that the ADSL is out of sync, and the network is in an interrupted state, and in most cases, there is a line failure.

If it is normal, you can use the card network speed test to test the network speed of your broadband Internet access.

act = Activity, usually the more frequent the lights flash, the more data passes.

The main control link is data acquisition.

Cats generally have four lights, normal times, power, adsl, lan, these three lights are always on, if there is one that flashes often is abnormal, the data light will flash after normal surfing.

If these lights are normal and can't get on the network, it is a problem with the computer, if the router is not installed, you can find the cause of the fault through the error ** obtained by broadband dialing, such as error 693, that is, the wrong username and password, etc.

If your computer is surfing the Internet through a router, you must first bypass the router and use the above method to judge. If the dial-up is normal and the router is not surfing the Internet normally, you need to carefully set the router parameters according to the router's manual.

If you can't even dial up, then you need to check whether the computer has any viruses and whether the network card driver is installed correctly.

Is that okay?

All four should be lit and the link is generally flashing all the time

The cat froze, rebooted.

Is the network card light on the computer? If it doesn't light up, change the line.

What's connected to the cat? Routing?

Is it that the cat is not connected.

The cat has the following situation when the red light is on:

1. The light port of the computer room emits low or no light, causing the user's optical modem to work abnormally, and the optical signal light cannot receive the optical signal sent from the optical cable or the power of the optical signal is too low, which will cause the optical modem to shake hands with the computer room abnormally, and the optical signal will flash or alarm with a red light.

2. Optical cable failure (including broken optical splitter) will also cause the optical modem to not receive light or the light collection is too low, and the optical signal light will also flash or alarm with red light.

3. The failure of the optical modem itself and the partial damage of the receiver will also cause this phenomenon.

No matter which of the above three situations occurs, users basically can't solve it, and they can only report the fault.

If the LOS light flashes red, it is preliminarily judged that the modem cannot receive the light signal or is too weak, you can follow the steps below to check further:

1. Please check whether the connection between the yellow pigtail and the optical cat is loose;

2. If there is any looseness, please reconnect it manually and restart the modem;

3. If the "LOS" light indicator continues to flash, please report the fault.

1. Optical fiber is broken (more likely).

2. The fiber pigtail is not inserted into the optical modem (check it yourself).

3. Optical modem failure (small likelihood).

4. Failure of the uplink splitter (generally this kind of failure, your neighbors around you can't use it.) As long as you are sure that the pigtail behind the optical cat has been connected correctly, you can only report for repair and let the master come to overhaul it.

China Telecom dials 10000, China Unicom dials 100010, and China Mobile dials 10086

If the LOS light turns red or flashes, it is usually caused by the following conditions:

If there is a problem with the optical interface of the optical modem, you need to replace the optical modem.

The indoor pigtail connection optical modem connector is loose, and the connector can be restored by plugging it in;

The bend of the optical fiber in the indoor part is too large. Excessive bending of the optical fiber will affect the total reflection transmission of the optical signal in the optical fiber, as long as the optical fiber is straightened;

If the outdoor optical fiber is broken or the optical port of the equipment in the equipment room is faulty, you need to contact the staff to report the fault.
