What the four indicators of the broadband represent

Generally, broadband modems have four indicators, which are POWER, LAN, ADSL, and INTERNET.

1. Power is the power indicator.

If this light is not on, then check if the power plug is loose and the outlet or power strip is on.

2. LAN, LAN indicator.

If the light is not on, check whether the crystal heads at both ends of the network cable connecting the computer and the broadband modem are loose, and whether the computer and the broadband modem are turned on.

This light is always on, which means that the network cable is normal.

3. ADSL, broadband indicator.

If this light is not on, it means that there is a problem with the line, check whether the cable connecting the broadband modem and the splitter is loose, or whether the wire connector is loose.

This light is always on, indicating that the broadband line (** line) is normal.

This light keeps flashing, indicating that the broadband modem is connecting to the communication company's server. At this time, the Internet software is not connected to the Internet, wait for this light to not flash, and then connect.

4. Internet, Internet indicator.

The telecom optical fiber modem optical signal light lights up red, which means that the optical fiber cat cannot receive the signal, so it cannot access the Internet, and the general reasons are:

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.

Generally, there are several indicators on ADSL: Power light, Test (or DiaG) light, CD (or Link) light, and Paizai LAN light, all of which have different indication meanings

test (or diag light): the device self-test residual group light. This indicator will generally only flash when ADSL is turned on, and will turn off once the device self-test is complete.

If the indicator light is on, it means that the device failed to pass the self-test, and you can try to reopen ADSL or reset the device to solve the problem.

CD (or LINK) light: Sync light. This indicator indicates the line connection. The CD light will stay on soon after turning it on, if the CD light keeps flashing, it means that the line signal is not good or there is a problem with the line.

LAN Light: LAN indicator. This indicator indicates whether your device is connected to your computer properly. If the LAN light is not on, the computer will not be able to communicate with ADSL, and of course it will not be able to dial up normally.

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

2. The indoor pigtail connection optical cat connector is loose. Plug the connector in and it can be restored.

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. The outdoor part of the optical fiber is broken, and you need to find the operator to deal with it.

5. If the optical port of the operator's equipment room fails, the operator also needs to deal with it.

First of all, let's explain this optical signal, the light of the optical modem is red, when it is on, it means that the optical fiber is broken, and it will definitely not be able to go to the network.

Normally, the optical signal and the network g will only light up one. I've seen a cat light signal that is green (the indicator is the same as the network gpon epon gpon|),Extreme joint (garbage light cat) I have encountered a red light and can still surf the Internet, but the simple light cat indicator light is broken, does not affect the Internet. If you can access the Internet, don't pay attention to him, you can be sure that the cat's indicator light is broken, if you can't access the Internet, you can replace the light cat.

power red, which indicates the power status. Lights up to indicate that the power supply is connected, and Link is yellow to indicate the ADSL line status. Flashing indicates that the line is connecting:

When it is always on, it means that the line is connected and can be used, data is green, when it flashes, it means that the modem is sending and receiving data, Ethernet is green, which is used to indicate the connection status between the PC and the network card, and when it is always on, it means that it is connected to the PC network card.

Introduction: A router is a computer network device that can transmit data packets to destinations through a network, a process called routing. A router is a device that connects two or more separate networks, and routing works at the third layer of the OSI model, the network layer, such as the Internet Protocol layer.

Main features: the router has the function of judging the network address and selecting the IP path, it can establish a flexible connection in the multi-network interconnection environment, and can connect various subnets with completely different data packets and media access methods, the router only accepts the information of the origin server or other routers, and is an interconnection device at the network layer. It doesn't care about the hardware devices used by the subnets, but it requires software to run that aligns with the network-layer protocols.

Extension: Routers can be found everywhere in all levels of the Internet. Access networks allow homes and small businesses to connect to an internet service provider; Routers in an enterprise network connect thousands of computers on a campus or in an enterprise; Router termination systems on the backbone network are often not directly accessible, and they connect ISPs and enterprise networks on the long-distance backbone network.

The rapid development of the Internet has brought different challenges to the backbone network, enterprise network and access network.

There are many reasons why the light signal of the e-Surfing broadband wireless router is bright red peina lamp:

1. There is a problem with the router program, in this case, you need to turn off the router first, wait for about 5 minutes and then restart the router.

Second, your broadband is in arrears, and now your broadband is a postpaid model, because your broadband arrears have been in arrears for a long time, the operator will disconnect your network, and this situation can be solved by paying off the arrears.

Third, the failure of the uplink splitter, this situation is that your neighbors around you can not access the network, and you need to report for repair and other workers to repair the door-to-door maintenance. Wheel block.

Fourth, the optical fiber in the area is under maintenance or failure, this situation is generally a large-scale network outage, and the only way to wait for the operator to repair the network.

5. There is a problem with the router's optical signal interface. It may be that the interface is loose, or the interface is not in good contact, in this case, you need to remove the crystal interface of the optical signal and clean it up and plug it back in.

Sixth, the router is broken, this happens very rarely, you can check whether the other indicators of the router are also flashing red lights, if they are flashing, it means that the router is broken, only to replace it with a good one.

3 pcs. When the broadband is working normally, there will be 3 indicators in a state of steady on, these 3 indicators are the power button, optical fiber, broadband, as long as these lights are in a state of continuous on, it means that the broadband in the home can be used normally.

The broadband lights are indicated as follows:

1. Power power light: Under normal circumstances, the indicator light is always on.

2. PON is a data light: under normal circumstances it is always on, if it is flashing, then it is faulty.

3. LOS indicator: the red light is on, interrupting the optical path.

4. LAN 1 Indicator: For broadband internet access, the indicator light connected to the computer or router is always on or flashing to connect properly. If the light is off, check your network, such as disconnected network cables, plugs not plugged in, faulty computer network cards, faulty routers.

5. LA2 indicator: used to connect to the set-top box of China Unicom TV. It always turns on or flashes normally. If the light is off, check that the network cable is connected correctly. Grind whether the crystal head of the banquet is loose, and at the same time diagnose whether the indicator light of the unconnected machine is flashing.

6. Phone indicator: fixed line indicator, the answering light is always on. <>

power indicator link refers to the status between the cat and the switch on the other end of the ** line data has data in the cat ethernet refers to the connection status between the cat and the computer.

Usually, there are 8 indicators on the modem panel, which dynamically reflect the working status of some signals of the RS-232C communication interface of the modem, and can be used to judge whether the modem is working normally. This section describes the status of the modem panel indicator when the modem is working normally, and if the modem panel indicator does not match the normal working state display, it means that the modem itself or communication may be faulty.

power refers to the power supply of the cat itself, which is lit for power.

Link refers to the state between the cat and the switch on the other end of the ** line, and the light is on for the broadband switch on the other end of the ** line is normally connected.

data refers to whether the cat itself has data exchange, and when there is data in and out of the cat, this light will flash.

Ethernet refers to the state of the connection between the cat and the computer.

Under normal circumstances, only the data light flashes one by one, and the other three lights are all on.
