Urgently seeking an expert, my telecom ADSL can t go online strange symptoms

Ping the telecom gateway to see the status. If everything is fine, then look for the problem of your own machine.

If it's your own problem, ask first, there is an air conditioner in your computer room, and now the weather is very hot, and it is easy to have problems if you don't turn on the air conditioner.

2. Check to see if the modon setting conflicts with a certain setting in your machine. This problem should be solved by looking at the Moden manual.

3. Check whether the distribution box of your home network end community is connected to this connector of your home and whether it is normal.

That's basically all there is to the hardware problem, find the software problem by yourself, redo the latest system, patch it, and install the software.

It is also possible to enter the safe mode with IE connection to make sure that it is not a software issue.

Hehe, I've seen similar problems many times on the know, and I suggest you check the separator.

The correct line connection of ADSL Internet access should be as follows: ** line to the line port of the splitter, the modem port on the splitter to the line (some called wan) port of the modem, and the phone port on the splitter to the ** machine. These three sections all use ordinary ** lines.

For the splitter, the modem port can be vented in the three ports, and then the LAN port of the modem and the computer network card are connected with a network cable.

Note that all ** must be connected to the separator, and any ** may often drop off if it is not connected, so be sure to connect all of them.

Telecom problems, complain, go to the provincial company to complain.

Try a different socket for your network card.

Reasons why broadband cannot connect:

1.The current network signal is unstable, sometimes none.

2.Computer hardware problems, network card module is damaged.

3.Improper network settings.

4.No driver installed or driver crashed.

A broadband connection can be made by following these steps::

1. It is recommended that you restart the computer and modem first to observe whether the fault still exists;

1) If the glitch disappears, it means that you may not be able to access the internet due to a problem with your computer or router (sometimes the router freezes and the user cannot open the web page);

2) If the fault persists, go to step 2;

2. Please observe whether the call is normal:

3. Check whether the modem signal is normal (you can confirm the signal light through the modem user manual):

There is no strict definition of broadband. From a general point of view, it is the bandwidth that can meet the needs of various ** transmission on the network that people can feel, so it is also a dynamic and developing concept. There are several reasons why the connection is not available:

The account number and password are incorrect, or your broadband has expired (if the bandwidth has not expired, please check that the account number and password are filled in correctly).

There is a problem with the created broadband connection (please delete the original broadband connection and create a new broadband connection) There is a problem with the network card driver (please update the driver or reinstall the driver).

The solution to the computer is not connected to the Internet.

It may be a signal problem, as soon as there is a problem, call 10,000, anyway, you spend money to install broadband and you have to enjoy the service you deserve, and keep calling until they solve the problem for you. Haha, it will definitely be done.

I also often encounter this situation, especially at noon I can't go up at all, it's useless to call telecom customer service, find someone to repair, they won't repair, say this is no way, your place is too remote, too far, the signal is not very good, I am very depressed, I don't know how much broadband you use, I use a megabyte, that's it.

Look at the link light is on, if it is not lit up for maintenance**, if it is a fiber optic cat, see if the light is red or not, if there is, it is a problem with the line.

The specific situation is not clear, first of all, see if the power and link lights on your moden are always on, if one of them flashes and flashes, then it is the problem of moden. If there is no problem with the moden, look at your network cable interface, the light that is connected to the computer is not on, and if it is not lit, it is a network cable problem.

If there is no problem, just call the 10000 fault repair directly.

Telecom is often disconnected, it may be a fiber optic problem, ask customer service.

This phenomenon is caused by three reasons:

1. The responsibility of the operator (transmission and switching network failure): the operator must ensure that the signal quality to the user (bandwidth, bit error rate, signal-to-noise ratio, transmission rate, signal level, input and output impedance, signal stability, and stability of input and output impedance meet national standards); Specific**:

China Telecom 10000, Netcom 10060, Tietong 10050

1: The server is unstable;

2: **'s software is unstable;

3: ** The quality level of operation and maintenance is low; Failure to troubleshoot in a timely manner; For example, if the other is very good, and a certain one is particularly bad, this is the problem of the company itself, and it has nothing to do with the operator or the user.

Three: the user (responsibility) The following factors will lead to your current state, if there is no problem with the above-mentioned operators after detection, next, it is your user's own problem to raise socks; If you don't have the following problems, you can directly call the operator** and ask the operator to deal with the operator's own related matters.

The reasons for this phenomenon and how to deal with it.

On the premise that the user's device settings must be correct:

1: Power supply Check whether the power supply is stable with a multimeter?

Are AC voltage fluctuations within the allowable range? Is it more than 5% of the rated voltage?

Is the ripple coefficient (checked with a millivoltmeter) acceptable after the power supply is converted?

Is the temperature rise of the power supply abnormal?

Do the voltage regulation characteristics meet the specifications?

Do the voltage regulation characteristics and ripple coefficient meet the technical specifications under rated load?

When replacing a large fan, is your power capacity up to the requirements?

The power supply of general auxiliary equipment (routers, network switches, cats, etc.) is a rectifier power supply, without voltage stabilization function, with a large ripple coefficient (which may be caused by the drying up of the filter capacitor), and the load capacity is also poor; If the equipment does not work due to heat, special attention should be paid to monitoring during operation.

Due to the overvoltage of the equipment (like feeding a child, more can support death), low voltage (like feeding a child, less will cause malnutrition), excessive voltage fluctuation (like feeding a child, hungry and full meal is not quantitative), overcurrent, heating, resulting in overheating protection action cut out of fault and equipment out of operation (i.e., slow, delayed, repeated start, delay, drop, interrupt, disconnection, automatic shutdown, crash and other appearances), etc.;

Are the overcurrent protection and over-normal trap heat protection of the power supply operating correctly? Is the movement sensitive? Is it refusal or misoperation?
