The computer is old and disconnected, and the telecom can t find it out. Hopefully someone will poin

The link light flashing is obviously a line issue.

In the case of not finding out what the reason is, first back up the data, personal information, favorites, my documents, etc., and then format the C drive, reinstall the operating system, after installation, install the motherboard-graphics card-sound card-network card driver, etc., and then create a new broadband connection, just dial to try to still like this, to change the cat, still not solved, hard point, the computer to get no problem with relatives and friends or the neighbor next door to see if it still drops after dialing? In order to surf the Internet, you have to work hard. Hope you get it.

My computer used to be the same, and when I called the telecom person and didn't come, I finally climbed up and got a screwdriver and it was done.

It is recommended that the computer system be rebuilt; **Line detection (with special equipment); Try it with a different broadband cat; Set a new broadband password; Let the local telecom check if there is a problem with the broadband binding...

My problem is the same, but it is only installed broadband, I am full of dizziness, at first I suspect that the built-in network card is bad, and then the cat, because my house is a new line is not a problem, I use not a telecom cat, it is tp-link, more when it is continuous down, your network cable is not plugged in, less when a few hours, on the contrary, it is very frequent, the network is not at ease, and then I changed the independent network card, or so, after thinking, there are 2 points not excluded, the first: The low voltage causes the cat to automatically restart to obtain IP, resulting in a drop in the line, No. 2: If you use another computer to put it on your home, it is still like this is the problem of the line or telecommunications!

I can only discuss it with you like this, at present, my problem still exists, and I am ready to buy a UPS with voltage stabilization function to see how the situation is, because I am here in the lower region of the continent, and it is not on the market!

Don't rush with the stars, try to build a connection yourself to land

Network problems, it is said that Tianwei often drops the line,

The answers of the previous friends are excluded and you can't get the question of the street. So you look at the environment in which you put the computer. There's the ease of heat dissipation and other factors that can touch the network cables.

Because the environment is warm.

The network cable has become softer.

The crystal head is loose.

Naturally, there will be poor contact. Then there is the problem of unstable Internet access...

I don't know what the reason is that I recommend you do the following:

1. Check whether all the wiring is loose, and also see whether the lower wire is damaged and whether the contact is poor.

2. The computer kills the virus, change the antivirus software, it is best not to use 360, use Kingsoft, etc.

3. Re-set the Internet connection, if there is a route, try to change the route.

4. Redo the system.

5. Borrow someone else's chassis and try it for a day or two.

6. If all of the above still exists, the problem of telecommunication and the unstable signal provided are basically determined.

Try to turn off household appliances that consume a lot of electricity.

Don't go online during peak hours.

Also, when surfing the Internet, it is best not to turn on household appliances, which are easy to fall.

The kind of old-fashioned light stick tube is the easiest to do.

You turn off all the household appliances and try them one by one to know how much power you are loading.

Although this is this method, but I am not a professional, I can only do this, hehe.

In addition, the voltage regulator does not play a big role, and the voltage is not very stable.

And it's an electric tiger.

Try to use smaller household appliances as little as possible.

It's possible that it's under attack, like an ARP attack, and so on.

At the interface between the network cable and the computer, you use a blade to gently scrape. Try to scrape the ADSL interface of the network cable. It should work.

Generally, it is a wiring problem, the wiring is damp, or the wiring in your home is pressed under the table leg or other heavy objects, resulting in poor wiring insulation. You can call the telecom customer service number 10000 first and ask them to send someone to check the line for you.

Dear Telecom users, Hello! Error 619 815 (Specified port is not connected, remote computer is not responding).

1) Check the modem status, if the sync light flashes or doesn't light up

Check whether the separator slag and ** extension are installed correctly.

If you don't connect the separator, connect the split ** line directly to the modem, and try whether the quiet light of the same source is normal (test whether the separator is broken).

Restart the modem.

2) If the LAN light does not turn on, check whether the LAN cable is connected properly, or restart the computer.

If you have any other questions, you can go directly to the Anhui Telecom network hall to ask questions, and there will be more professional customer service to answer for you.

The second is a blind green light that keeps flashing. Your cat is Huawei MT800 (the first light is a power light, the second is a signal light, the third and fifth are flashing when you surf the Internet, and the fourth is a local connection light).

It's clear that the signal is being acquired. There are several reasons for this:

There are only four reasons why a signal is flashing.

First, does the cat have a fever? Heating can also break the wire. (Report No. 10000, ask for a replacement).

Second, is there still a murmur? A murmur indicates a problem with the telecommunication line.

Third, check if the separator is plugged in backwards? p starts with ** and m starts with network.

Fourth, if the above three are normal, there is a problem with the terminal of the telecom room.

The letter and travel god are flashing, except for the second item, which can be dealt with by yourself, you have to call 10,000 to report the problem.

I'm going to tell you, it's definitely not God who destroys your computer.

If it's old and out of line, you still have to wait for the infrastructure construction of the telecommunications department to be completed and then try to be stupid, and then divide it into two sides, the first is to confirm that there is no problem with your computer, and second, to confirm that your dialing modem is no problem, if you confirm that you don't ask the question of checking and balancing, you can directly find someone from the telecommunications to come over, and you don't have to worry about the rest;

Take a look at whether the ADSL cat's external network light keeps flashing when the connection is dropped, if so, it is a telecom line problem.

You can take a look at the erection stool.

I don't know if it's helpful to you.

This one of yours is likely to be:

1. See if someone changes the IP of their computer to the IP of the server.

2. Some people use P2P terminators, network law enforcement officers, Jusheng network management and other software to limit the speed of others and do ARP deception.

4. Flood packet attacks are generated on the intranet, and spam packets block the entire network.

The immunity wall is specifically for LAN security and management, and we can think of the immunity wall as such.

1. It is a set of intranet bottom firewall: the vertical key completely solves the network attack of viruses and Trojans, the problem of disconnection and stuck (especially the processing of the layer). Solving the problem of ARP (Innate Immunity, ARP Exploration) is unmatched.

2. It is a set of real identity access system: strict and effective management of the identity of the terminal computer in the network (real IP, MAC, CPU hard disk, motherboard, genetic). Completely solve IP spoofing (private cables, cloning, IP conflicts).

3. It is a set of network bandwidth management equipment: fine intranet bandwidth management, load balancing, traffic statistics (intranet and intranet, server, application delivery).

4. It is a comprehensive network management software: observe the internal protocol process of the network, remote debugging management (monitoring center, audit).

4. It is a comprehensive network management software: observe the internal protocol process of the network, remote debugging management (monitoring center, audit).

Dear users, hello! It's a pleasure to serve you.

According to your description. You can judge the handling for the following reasons:

1) The quality of the NIC is unstable.

The fault phenomenon is that once the network is disconnected, it can no longer be connected. If the line synchronization lamp (ADSL lamp, DSL lamp, or Link lamp) of the modem is always on, the fault of the external line is basically eliminated, and it is generally judged to be a NIC problem. If you can eliminate the problems of network cables, computers, and slots, and judge that the quality of the network card is unstable, you should replace the network card in time.

2) Internet access and phone calls cannot be done at the same time.

The fault phenomenon is that the microphone network will drop when it is lifted. Generally, it is poor insulation of the outer wire, or poor contact of the first wire joint, or the quality of the separator is not good.

3) Wrong series connection ** extension.

Due to the wrong connection of the ** extension, it causes crosstalk and causes the Internet to be disconnected. Note that do not connect the ** extension in front of the separator, but connect the extension behind the separator.

4) modem heating.

Since the modem has not been turned off for a long time, the modem will be overheated and the Internet connection will be unstable, so it is recommended that you disconnect the modem power supply when you are not using the Internet.

5) There are high-power electrical equipment next to the modem.

In this case, it is easy to cause the network signal to be interfered with, so it is recommended that you do not place some high-power electrical devices such as mobile phones and refrigerators next to the modem.

At home, there are only four network cables connected to the home, which is not completely connected, and it is inevitable that the connection will be dropped, so it is best to re-wire. The specific method is to find a professional, not simply one-on-one.

Alas, monopolies are like that!
