Regarding the problem of my Internet disconnection, the master came to help Ha heavy money

This is usually caused by a virus known as "Magic Wave", which is caused by a system vulnerability in Microsoft, which was exploited by hackers. If you are hit by the virus, it will happen: a dialog box will automatically pop up during the Internet access, and then it will automatically disconnect from the network and you can no longer connect to it, but the system can go online again, but after a while, the above situation will happen again.

This is a hacker exploiting Microsoft's system vulnerability, so it is useless to reinstall the system. Microsoft has officially released a system patch a few days ago, and this is Microsoft's official system patch address in China.

Just put on this patch and you'll be fine.

Characteristics of the Magic Wave Virus Attack:

When the connection is dropped when surfing the Internet, double-clicking the dial-up software does not work. You need to restart before you can surf the Internet.

XP system, right? It is recommended to turn off the firewall that comes with the system, so that there will be no problems you mentioned, for security, and then use Skynet or other firewalls yourself.

The way to turn off the system's built-in firewall is as follows:

Start - Control Panel - Network & Internet Connection - Network Connection - Local Connection - Right-click Properties - Advanced - Firewall Settings.

One of the cases of disconnection is computer poisoning, cleaning system plug-ins, scanning and killing Trojans, repairing the system, upgrading the browser, etc.

There is also a network cable that is not well made and easy to drop.

The network equipment is overloaded. For example, the utilization rate of routers is too high. When the number of connections reaches the upper limit, packet loss and packet drops will also occur. If the network is disconnected, you need to replace the access device.

Troubleshoot the above issues. It is that the fiber access provided by the telecommunications sector is unstable. Then you can request a warranty, telecom on-site maintenance.

Check the network cable first, kill the virus, and then don't find customer service.

The ADSL light flashes to indicate that the wideband signal is unstable. There could be 2 reasons for this:

One is that the power supply of cats is insufficient, many cats are powered by very heavy transformers, and the output voltage is insufficient when the mains voltage is low, resulting in cats not working properly. The solution is to change the cat to an electronically regulated power supply.

The second is the problem of broadband lines, the line between the service provider and you plus is aging, the distance is too far, and there are interference signals in the middle. You need to contact the broadband service provider to solve this for you.

If there is a problem with the device status light, ADSL and INT light are off, it may be a problem for the cat, you can find the operator to replace the cat to see.
