What s the matter with the computer that can t connect to the Internet all the time?

If the computer is not connected to the Internet, there are only a few reasons.

First, the problem of the network.

Now the problem of the network is not common, not like the previous network is unstable, but now with the development of science and technology, the network is becoming more and more stable, basically there will be no big problems on the network of the telecommunications provider, but this situation is not ruled out, if you can't get on the list occasionally, you can directly contact the customer service on the network to see if there is a problem with their network.

Second, the problem of network cable.

There is always no Internet access, and it may be because the network cable has poor contact, especially the network cable, there is a head on it, and this head is easy to break.

Therefore, it is recommended that you buy a new network cable to re-see whether it will still produce the situation of not being able to access the Internet.

The cost of the network cable is relatively small, you can buy a shorter one to try, if it is a problem with the network cable, then try to change a new network cable.

Three, if it's wifi, it's likely to be the router's fault.

If your so-called network is not a network cable, but uses wifi, that is, wireless, it may also be the reason for the router.

Today's routers all have a useful life, which is the so-called shelf life.

If you use it for a few years, two or three years, this kind of heating of the router for a long time can easily burn out the contents of the router.

And now people have a habit of using routers, that is, they don't like to switch on and off often, and sometimes they don't turn off once a month.

So you can try to turn off the router for a while, and then turn it on to see if you can surf the Internet.

Fourth, the problem of IP settings.

If you need to go to the Internet on the computer, you need to set up the IP, and if you have a supplement to the IP settings, there is no way to connect to the LAN, in this case, there is no way to access the Internet.

Therefore, specific problems still have to be analyzed in detail, which can be eliminated little by little, starting with the simplest.

The first thing that should be thought of when connecting to the Internet is whether there is a problem with some settings of the system, then you need to set the system network connection accordingly. Right-click on the network icon to open the network sharing center to see what the network connection is like.

If the computer is not connected to the Internet, it should be that your home network is not good, you can try to connect it with an Internet cable.

If the computer is always connected to the Internet, my solution is to find nearby students, because they are very smart, they can help you, we are old.

You first check whether the crystal plug of the network cable is loose, click on the computer, then open the device manager, find the network adapter point to deactivate, and then start it, maybe it's fine. If not, don't be angry! Sit back and have a cup of tea in the hot summer, the temperature is very high, don't you feel hot?

You put me here, and you don't care about me taking the rounds; The temperature of my chip is above 40 degrees, the temperature of the hard disk is higher than 45 degrees, and the temperature of the network card is more than 80 degrees; Can you work in such an environment? You still have a fan or an air conditioner or something, do you mind my business? Our equipment (stupid slippery equipment means:

Cats, routers, network switches, Hubble, computers, etc.) too, feel hot and can't work for you anymore; You can't go to the Internet, you look for masters in the north and south, don't cool me down, you can't find anyone (or replace cats, routers, etc.), because our brothers have the same temper, if you don't cool us down, we will strike! You may wish to take a look at the following methods, and use measures that you feel are acceptable to reduce the temperature of my (equipment) working environment, I promise: continue to serve your elderly.

A: Users who often surf the Internet for up to half a year should open the shell of the device after the power is off and clean up the dust inside the device. b: Place the cavity equipment in a safe place for people, open the lid of the equipment, and use air convection to strengthen the contact with the air for natural heat dissipation;

c: Install a micro fan to the equipment to increase the convection of air and force heat dissipation;

D: If you are doing IT, I suggest that you install a heat sink on the heating part of the device after disconnecting the power supply.

e: After the equipment is disconnected from the power supply, use a 3mm drill bit to drill many holes up and down the equipment to strengthen the air convection flow and improve the heat dissipation conditions;

f: To ventilate and dry the equipment, it is best to make an insulated heat dissipation bracket (there are also notebooks on the market) to support the equipment for natural heat dissipation;

H: Let the adsl cat sync first: power off the cat and restart it.

i: The software settings are reasonable, so that 3 do not install: do not install informal software, do not install P2P (occupy resources) software, and do not install infrequently used software.

Turn off all unnecessary network connections, such as Thunderbolt BT Donkey, etc.;

j: Optimize the network Personally, it is recommended to use some gadgets such as Super Rabbit, Optimizer or 360, etc.K: The computer should have at least one valid and genuine antivirus software installed l:

NIC problem: The NIC has the appropriate bandwidth and works stably. As long as you take care of our brothers (routers, cats, hubble, network switches and their computers), our brothers promise to really do it:

You respect me, I respect you" for your faithful service. Otherwise, ride a donkey and read the record book--- let's see!

Thank you for my answer!

Thank you: friend!

1. In the case of LAN, when you are the only one who cannot connect to the network, right-click "Online Neighbor" to check whether the "Local Connection" is normal. If the small computer is crossed, you can judge that the network is not connected properly, at this time, check whether the network cable interface is loose, and plug it in again. If this persists, check whether the network interface between the machine and the hub or switch is loose.

2. If you can't see the "Local Connection" indication, then right-click to open "My Computer" - Manage "--Device Manager", check whether there is a "network adapter", if not, then you can judge that your network card is broken, poor contact or the network card is oxidized. Solution: Remove the network card, erase it with an eraser, and then reinsert it, repeat the previous inspection method, if it still does not work, replace the new network card.

3. First see if your neighbors or friends who use the common network can access the Internet, and judge whether there is a problem with the entire network. If they can't get on either, check that the switch, hub, or fool-proof router is working properly. The main thing is to check whether their working indicators are flashing as usual, or to find the relevant department for maintenance.

Check whether the local connection is well connected, if it is connected, it is not a local problem, it is the operator's fault on their side! If the local connection is crossed, check whether the network card and network cable are damaged! If it's broken, change the network card or re-pull the network cable!

There is also a check whether the network card driver is installed or not, and whether there is a problem with the router settings!

Please check whether the NIC driver is installed! Is the network cable plugged in, and whether the router is working properly?

1, **, and the web page is no one to do it, and no one is to maintain it.

2. The computer is not connected to some servers, or there is no ** at all.

3. The built-in network card does not open some applications, and the networking function is not turned on.

4. Whether many network hardware facilities are in good condition. All need to be checked.
