Who knows that a normal computer is always disconnected from the network intermittent connection .

It's possible that your home has a low voltage.

Summary. Dear Kiss Glad for you, why does the computer connect to wifi always disconnects every once in a while, and then connects to any network shows that it cannot connect to the network as follows: 1Check whether network devices, such as routers and network cables, are working properly. 2.

Check your computer's network settings, such as IP address, DNS server, etc.; 3.Check whether the wireless network card driver of the computer is normal, if not, you can try to update the driver; 4.Check whether the wireless network card of the computer is normal, if not, you can try to replace the new wireless network card; 5.

Check the signal strength of the wireless network, if the signal is too weak, you can try to replace the stronger wireless network card; 6.Check the security settings of the wireless network, and if the security settings are incorrect, you can try to set them up again. 7.Check whether the virus on your computer is affecting your network connection, and if so, try to remove it with antivirus software. 8.

If none of the above steps resolve the issue, you can try reinstalling the operating system.

Recently a lot, please remember to take care of yourself, drink more lemon warm water, rinse your mouth with strong salt water, wash your nose Greetings across the screen, although silent, are also warm I am willing to send you to talk about the acres I am safe and happy Dusty and protective do a good job of protection

1. Try a good network cable. If it still doesn't work, it's a problem with your router or computer.

2. In the operating system, match the working mode of the network card with the router, such as automatic, full-duplex, and half-duplex. Different routers have different default rates, so they may have different results. (The probability of a problem is relatively small).

3. Use other computers to connect this cable, if there is no problem, it is a problem with this computer. (There is a problem with the network card or system).

4. Restart the router, if it doesn't work, clear the configuration and reset it to see if it can be solved.

Hello, update the graphics card driver to try, if this problem still exists, you can contact the ** business of the network for further verification, I hope it will help you.

1.Check the plug first. A plug to connect to a computer and a plug to connect to a router or broadband port.

2.Update the NIC driver. You can use the general driver software. For example, driving sprites.

3.If it is a router, it is recommended to reset it and set it up again.

Error 678 The remote server wood responds. This only means that there is a problem with your internet connection. It is likely that it is a problem with the network cable, and it is recommended that you carefully check whether your network cable interface is tightly connected.

In general, 678 errors have little to do with the drive. It's also possible that the servers of the service provider, China Unicom or Tietong are suboptimal. Maintenance required.

You can call ** to appeal. Call them in for a technician to solve the problem.

There is also a possibility that the integrated network card will burn out. You rule them out one by one.

What do you use to access the Internet, whether you use the cat directly or use the route, if it is a cat dial-up Internet, it may be that the cat has a problem, if the route is not known to be used by several machines, network speed.

The possibility of the computer not receiving the data and falling off the network is relatively low.

In general, it is best to specify the IP of the computer connected to the router, and the following points need to be noted.

1.The IP address of the router must be on the same network segment.

That is, if the router IP is, then the IP of all computers is to.

2.IPs in the same network cannot be duplicated, so it goes without saying.

3.Subnet mask.

There are only 2 forms, for the type of IP, the subnet mask is that this is the same for all computers. This type of subnet mask is and is all the same.

4.The gateway, very important, is the router IP, and the gateway of all computers should be the same.

Very important, this needs to refer to the status display of the router, enter the management interface of the router, check the status of the router, the page will display the connection status of the router, and the DNS will be displayed on it, fill in according to this DNS.

If the first one is automatically obtained by the state gear wheel but can be on, it is also accidental, because some routers have the function of configuring the mirror signal, but it is not very stable, and the computer behind it may not be able to configure it correctly, or it is better to set it manually, and the speed is relatively fast, saving time to automatically obtain configuration information every time it starts, dragging the speed. Therefore, the latter ones should not automatically obtain the IP according to the first station.

Please refer to the manual of the router for details, and the manual of the router of the general manufacturer is very detailed.

It's not about the system, it's mainly about setting up the gateway or something, the IP address.

You want to route the gateway address on the same network segment.

Whether the IP is static or dynamic, it should be the IP error that came to the computer that was turned on. Click 'Start' 'Settings' right click 'Network Connection' to open, right-click 'Local Connection' right click 'Properties' to select 'Intero Protocol' and 'Automatically get IP address' 'Automatically get a DNS server'.

Address' and then tap 'OK' 'OK'.

1. The network cable is not in good contact

2. The router address pool is overflowing, and it is impossible to balance it! Unless you have more than 200 computers with one network cable!

3. This situation will occur when the network slows down and blocks the network business, such as the expiration of broadband.

Signal problem, I haven't heard of this kind of Trojan for the time being.

The wifi has always been used so proven, not a broadband problem.

It should be a setting or hardware issue.

1 Maybe the network card is not good, reinstall the driver or change the network card.

2 If it is a dial-up cat, the shunt is not installed**, and the network is disconnected in and out.

3 Computer Poisoning Reinstall the system.

4 There are vulnerabilities in the system Try the next software like 360 Security Guard.

Let's talk about the problem of setting, try this aspect first.

Click "Start" in the bottom left corner of your computer - select "Control Panel" - click "Network and Sharing Center" - click "Local Connection" - click "Properties" - click "Configuration" - click "Advanced" - turn off all options with the word "IPv4"! And turn off "flow control" too! - Okay, just click "Save" all the way.

If the network is still frequently disconnected after setting, follow the above 4 methods to solve the problem.

The mobile phone can always use wifi, indicating that the broadband is normal, such as the computer suddenly disconnected from the network, it may be that the network card is not plugged in or there is a problem with the network card driver, it is recommended to reinsert the network card or reinstall the driver to try again, and pay attention to whether the network cable and network card interface are normal, you can try to change a network cable.

In addition, if there is a problem with the working mode of the network card, it will also affect the use, you can find the "My Computer" icon of the computer, right-click, select "Management - Device Manager - Point to Network Adapter", find the network card, and then right-click the network card, in "Properties--- Advanced - mediatype or link speed", set the working mode of the network card to 10m half-duplex.

Restart your router and see.

Test the network cable to see if there are breakpoints.

Check the host power supply.

Reinstall the system.

1.Problems with network cables. Because the quality and transmission of the network cable are closely related, if the connection is broken, sometimes it is because of the connection problem of the network cable.

If you want to know if it's a problem, you can take a look if the crystal head of your network cable is showing a yellow light if it is broken. If it is displayed, it is passed. If it is not displayed, it means that the network cable or network card is not working.

2. Network card problems. If you're off, ping to see if there's any data coming through. No, the network card is not connected to the outside world.

But I think the first one might be bigger. I mean, if you disconnect, check if the crystal head is on. If it's on, it's a problem with your network card.

You can use a network card to insert it into the slot, and the crystal head is connected to see if it is still broken. If it's broken, it's not a hardware problem. You see if there is a virus in the process. Because having someone remotely controlling your machine will also result in the size of the traffic.

In two cases, one may be that your computer is poisoned, and the other is that your network is very unstable, and you can redo the system If it is still like this, it is basically certain that your network is a problem.
