My family is always off the Internet, and the cat indicator light is as follows, what is the reason

There are several situations, 1, your cat has a problem, that is, it is not in contact or something. (Go for a repair, or replace it with a new one) 2, the problem of power supply voltage. 3. The shunt is very important because it is related to the connection between the two sides.

4. The problem of the port and the **, that is, the interface out of the port and the interface of the ** interface and the shunt line. 5. The reason on the side of the Netcom company (telecommunications company). 6. The reason of the system, what software in your system may cause the network cable connection to be unstable!

I suggest you use two methods, 1, which is to repair the cat, and 2, which is to rebuild the system.

ADSL Link is a signal light that is always on normally.

There are a variety of reasons.

Lines, ports, cat temperatures, splitters (filters), installation methods of **extensions, etc.

The specific inspection method is:

1.Listen with **.

A-Pick up** and press a number key casually, listen to ** whether there is the sound of ji ji, and if there is a separator (filter).

b-** line do not pass the separator directly to connect **, pick up** press a number key casually, listen to whether there is noise in **, there is a line caused by poor contact.

2.Observe the running time of the cat.

If you just turn on the power of the cat and do not drop the line, hang the line after a period of time, and restart the cat can be used for a while --- change the cat.

3.**If the line has a connector, reconnect it all.

4.The ** line from the outside is advanced to the separator, and the ** line from the phone port of the separator can be connected to the extension.

5.Let the Netcom repairman help you change the cable or port to try.

It may be a problem of temperature and voltage, which can be caused by too high a temperature or unstable voltage;

In addition, I am afraid that as I said upstairs, there is a problem with the shunt, and I want to change the shunt, but there is nothing that can be replaced.

Link represents the network cable out of the ** line, Link is always on means normal, when flashing, you can unplug the crystal plug of the ** line splitter, ACT data light, flashing means normal, you can unplug the crystal plug between the network cable and MD when it is not lit, if the link flashes when the line is dropped, please check whether the splitter plug is loose? Just plug it in and you're good to go.

It has little to do with cats, you look at your shunt, which is a small box that connects the cat while connecting the **.

Try it differently.

Call **10000 and they will solve it for you.

The normal situation of the net cat is that the 3 green lights are always on.

They are Power Lights, PON Lights, LA1 Lights, or LA2 Lights.

Netcat Indicator:

The power power light reflects that the indicator light is always on. PON is a data light, which is solid under normal circumstances, if it flashes, it is faulty. LOS indicator, red light indicates that the optical path is interrupted.

LAN 1 indicator for broadband Internet access, the indicator light of connecting to a computer or router is always on or flashing to indicate that the connection is normal. If the indicator light is not on, please check your own network (if the network cable is broken, the crystal head is not plugged in properly, the computer network card is faulty, and the router is faulty). The LAN 2 indicator is used to connect to the set-top box indicator of China Unicom TV, and it is always on or flashing to normal.

The indicator light does not light up, please check whether the network cable is out of order, and whether the reconnection is normal. Whether the crystal head is loose or not. The indicator light of the missed phone is flashing.

phone indicator, fixed-line indicator. The pick-up indicator is always on.

Difference Between Wireless Cat and Router:

1. The ports are different.

Wireless routers are most common with 4 ports, with obvious antennas as identification marks. The cat has two ports, the ** cable and the RJ-45 port, that is, the network cable.

2. Different uses.

The router is connected to the cat via wired or wifi, and the top is connected to the computer. The cat is connected to the ** line above, and the router is connected below. Dial-up Internet access is only possible when the computer passes through it.

3. The settings are different.

The cat basically does not need to be set up, and the router is set up by logging in with a fixed IP address, and there are some complicated steps, but the security is high. <>

They are power, gpon, and lan1 indicators. For home gateways, which are currently the most widely used, some optical modems will also have Internet and LAN2 indicators.

The power indicator is the power indicator, which is green and solid when the modem is powered on and the power switch is turned on.

If the GPON indicator is solid green, the GPON interface has received a downlink optical signal, and if it is normally off or flashing, there is a problem with the optical fiber line or interface.

If the indicator is solid green or flashing, the connection to the wireless router is normal.

Differences between optical modems and routers:

Internet access must have an optical modem, and only with an optical modem computer can dial-up Internet access. However, there is no need to have a router to access the Internet, and a router is just a device that helps multiple computers share a network.

The shape of the optical modem and the router is very similar, which is one of the reasons why we can't tell the difference. However, there is a big difference between them, and that is the port. Optical modems generally have only two ports, while routers have more ports, usually four.

After activation, the optical modem does not require any settings, and can be used by plugging in a network cable or connecting to a wireless network. The router can only be used after logging in and setting up, and the setup process is complicated. <>

The normal situation of a fiber optic modem is that there are 3 green lights that are always on, which are power light, PON light, LA1 light, or LAN2 light.

Power power light: The normal reflection is that the light is always on. PON is a data light, which is solid under normal circumstances, if it flashes, it is faulty. LOS indicator, red light indicates that the optical path is interrupted.

How the optical modem works:

The equipment of the optical modem adopts a large-scale integrated chip, with simple circuit, low power consumption, high reliability, complete alarm status indication and perfect network management function.

The optical modem is a device similar to the baseband modem (digital modem), which is different from the baseband modem in that it is connected to the optical fiber dedicated line, which is an optical signal. It is used for the conversion of photoelectric signals and interface protocols in the WAN, access router, and WAN access. The optoelectronic transceiver uses the conversion of the photoelectric signal in the local area network, but only the signal conversion, and there is no interface protocol for the conversion of the file hall.

Application range of optical modem:

Speaking of Ethernet modems, it is mainly used when the distance is more than 20 km and the intermediate needs to be transferred through optical transmission equipment such as SDH and PDH. Generally speaking, the rate of the modem is packaged on a 2m circuit, so the difference between the optical transceiver of the modem is also its rate, the optical modem is 2m, and the optical transceiver is 100m. <>
