Telecom broadband, the cat on the LAN old flash, what s going on?

Generally is made of.

Caused by carrier lines, modems, routers, etc.

1. The cat has been open for a long time, it is very hot and hot, it is recommended.

Try to place the cat in a ventilated place and not overlap the router. so as not to overheath the temperature. Not really.

It is recommended to change to a cat with good performance.

2. Several computers share the network, because the router is too poor, others use P2P to watch movies, etc., it will drag the router to death, and the router will be better if you restart it, and the long-term solution is that it is recommended to change to a better enterprise-level router.

3. The operator's computer room is far away from home, which is beyond ADSL

Distance, line failure, etc., then it is necessary to telecommunications to measure the signal strength, and the line situation (sometimes two lines, broken one can also go online, but the network speed is slow, easy to drop, ordinary people can not find).

Playing games (the type of CF you said) The bandwidth needed should not be too high,You see if there are multiple people connected or someone rubbing your network,Generally, there is no ** or watching network TV will not be stuck,Of course, you are connected to telecommunications,Play Netcom, that's another story。

Under normal circumstances, the optical modem power light is always on,LOS offPONConAlways onLAN and other always-on voice lights depending on the situation,Yes**That is, it is always on,If the LOS light flashes red, then there will be a problem with broadband,lan2The light flashes, as long as the network is smooth, this is normal。

The LAN 1 light indicates that the LAN port and the Internet terminal are physically connected, but there is no data transmission. For the situation in question, the optical path should be repaired first, and then the maintenance personnel of China Unicom should register the optical modem, and the user should keep the power of the optical modem on during registration.

Indicator light of the light modem:

1. Power: The power indicator will definitely be on when the optical modem is powered on. If it doesn't light up, it won't be powered on.

2. PON light: business indicator light. Normal state, steady on; If the user data on the modem is not configured or lost, the state is flashing. In the case that the optical path of the optical modem is blocked, the state is off.

3. LOS light: light signal indicator. When the optical path is normal, the state is off; If the optical path is blocked, the status is flashing red.

4. LAN light: network port indicator light. In the case of a communication connection, the status is solid; In the case of normal Internet access and data transmission, the status is flashing; In the case of a network port fault (no communication connection has been established), the status is off.

5. WLAN: Wireless WiFi indicator, when WiFi is turned on, the status is always on; When there is a wireless device connection and data transmission, the status is flashing; In the case of wifi off, the status is off.

6. phone: voice indicator, if there is a fixed phone, plug it into the landline, and the status is always on; In the case of normal call and data transmission, the status is flashing; In the case of a network port fault (no communication connection has been established), the status is off.

The Broadband Optical Fiber Modem (ONU) LAN light represents the network line indicator, and under normal use, the green light will flash.

1. The LAN light is flashing, but you can't access the Internet, then your network is normal and you have dialed up to access the Internet, please troubleshoot other problems.

2. If the LAN light does not light up (go off), you can troubleshoot the problem by pressing the following methods:

Is the network cable plugged in tightly?

Whether the port connection is correct.

Whether the network card, computer, or wireless router is broken.

The optical modem lan2 keeps flashing, and under normal circumstances, there is data flowing, which is normal; If the optical fiber is not connected, then you should consider whether the interface is broken.

In general, LAN2 corresponds to the IPTV socket, and in normal use, the LA2 light flashes green.

Light cats. The lan1 light keeps flashing is not a device failure, it is a manifestation of the normal transmission of network data, which belongs to the normal working state.

The LAN indicator of the modem has the following three states:

1. Solid green: the port has been connected to the PC normally;

2. Flashing green: The port is exchanging data with the PC;

3. Off: The port is idle, or the connection with the PC is abnormal.

This kind of indicator light is relatively common, and generally home routers will have this indicator light, which is generally called Ethernet.

Light. Generally, this light is used to indicate the connection between the modem and the computer. Note: The LAN port indicator indicates that there is a LAN port on the back.

The cat will only flash a red light when it is first activated.

Normally, it should all be green or yellow in the future.

If your cat keeps flashing a red light.

That means the cat is broken.

It is recommended to replace a cat.

If the LOS light on the optical modem turns red or flashes, it is generally faulty, as follows:

1. There is a problem with the optical interface of the optical modem, and the optical modem needs to be replaced.

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

3. The bending of the indoor part of the optical fiber 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;

4. If the optical fiber of the outdoor part is broken or the optical port of the equipment in the computer room is faulty, it is necessary to report the broadband fault, and there will be staff to come to the door to troubleshoot the fault after the fault report.

Hello, the blue light flashing of the fiber modem indicates that the optical modem is being re-registered, and the flashing light of the optical signal indicates that the power of the optical module is abnormal. In this case, the modem is faulty, and the power of the optical module is abnormal, causing the modem to be re-registered. Anhui Telecom*** is at your service.

This is because the optical modem failed to receive the signal from the optical fiber.

If it still persists, you can report to the carrier's customer service for repair.

There are several causes and solutions:

1. Broadband arrears: Broadband is basically postpaid, and operators will shut down broadband services because customers are in arrears, in which case they only need to pay off the arrears.

Second, there is a problem with the broadband interface of the router, and the crystal plug of the interface is loose or the contact is poor, which will also cause this to happen, and the crystal interface needs to be dialed out and cleaned up before being reinserted into the broadband interface.

3. The router crashes, sometimes the router will have an internal program error, at this time, you need to turn off the router for 5 minutes before restarting it.

5. Regional network maintenance or repair, it may be that the network in a region is broken, and the maintenance personnel are repairing, you can call the telecom customer service to understand the situation and wait for the maintenance personnel to repair it.

6. Failure of the uplink splitter. If the uplink splitter fails, the routers around you will also have the same symptoms as you, and in this case, only the warranty will wait for the staff to come to repair.

The G light flashes blue, indicating that the device has no data, which may be data loss or the operator's device is disconnected.

Suggestions: 1. Restart the modem to try;

2. If you still can't access the Internet after restarting, it is recommended to call Telecom 10000 for repair and let the staff come to you for maintenance.

The bright blue light of the optical fiber of the telecom optical modem indicates that the optical modem cannot receive the signal. It may be due to the network cable not being connected properly, the network cable is broken, and there is a problem with the internal line of the network cable.

1. The optical fiber fusion at the joint is unqualified or broken; 2. The cold connector at the splitter box is not plugged in well or the cold connector is broken; 3. The connector at the optical box is not plugged in; 4. Somewhere in the line is damaged or broken, etc.
