If the old connection is lost, it will automatically connect again.

Most of them are ARP virus attacks, or change cats or routers.

Elimination minimizes testing.

1. Use only 1 of the 4 machines to test, and then increment them one by one to see if it is a virus in your computer;

2. Change the route, change the cat, and change to the ** interface on the wall one by one, is the template you said here?

3. The template you said I understand is the interface module used for termination, it is not excluded that it is a problem, you can only try it again, but generally this thing is faulty, and it can't be played normally;

4. Isn't telecommunications slow to come? Complaints!!! Resolutely complain and directly hit the fault table**.

That's it for the whole set of eliminations, which should be solved.

Most of them are ARP virus attacks on the intranet (one of the 4 machines will be poisoned and will spread internally to other machines) It is recommended that ** 360 already have? That's simple, just open the ARP LAN protection inside the protection.

Receive check to see if it's a cat problem or if there is an ARP virus attack, and there may be a telecom problem, it could be that there are too many users.

Or the network congestion thing, now broadband can choose more operators, if you live in the community that most of the telecommunications you live in, you have to choose Netcom or Tietong so that you can avoid network congestion.

In addition, you can start running and enter msconfig to disable all startup items, so that your computer can avoid running redundant programs on your computer.

1. If there is a software error in the operation of the WiFi router, it is recommended to power off the WiFi router and restart it.

2. Put the WiFi router in an environment with good ventilation and heat dissipation to ensure the stability of the WiFi router;

3. Reduce the distance and physical obstacles between the mobile phone and the WiFi router to ensure good WiFi signal coverage quality;

4. If the above reasons are ruled out, it is likely to be a problem with the mobile phone system for a long time, it is recommended to restore the factory settings or flash the phone to see if it can solve the problem.

When did you drop the line, and now it is not long ago, it was telecom that engaged in maintenance, so I went back like this, and mine is the same.

It's the network not connected. There is a problem with the network cable, or there is a problem with the network card.

It may be that the network card is loose or the crystal head is loose, change the network cable to see.

My machine has been like this recently, and after the connection is dropped, it is repaired at the local connection point, and it is not used to connect the broadband directly without the router. I reinstalled the system. In the Local Connection Point Properties, check only the last two items.

Now it doesn't drop, and the internet speed is much faster. I also read what others said, saying that there may be a problem with the ISP of the operator. But I think if there is a problem with the ISP, the connection cat will also be disconnected.

Anyway, I've got it, you might as well try it.

Don't reinstall the system just yet. That's too much trouble.

It could be a virus.

System reinstallation or one-click restore.

If the problem persists, it is the network or network device (broadband modem).

It is recommended to check whether the crystal head of the network cable or the network cable is broken, and the contact is generally not good!
