What happens if the computer is not connected to the Internet all the time?

In this case, the DNS is hijacked, and you can use PC Manager to fix it and see if it can be solved.

1. Clear the DNS cache. This is mainly used in some ** situations that cannot be opened.

First, press the windows + r keys at the same time, enter cmd in the pop-up window, and press enter.

In the pop-up command prompt, enter ipconfig flushdns and press Enter.

2. Reset the winsock directory, enter netsh winsock reset in the command prompt, and press enter. After the reset is successful, restart the computer. This command is very easy to use.

It is caused by a router problem, we need to check whether the router light is normal, if it is a light modem, generally except for the LOS light is not on, the other lights are on. You can turn off the router and the modem, and then turn it back on after 5 minutes.

You first look at the same network in other computers or mobile phones and tablets can be networked normally, if not, it is a problem with the router, if you can, check whether the computer network cable is plugged in, if it is a wireless network, see if the wifi connection is normal, if this step is still normal, check the wired or wireless driver, if these are all problems, install a network management tool, such as 360, poor dns or something.

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!

The computer network has not been connected, what is the reason?

If your computer's network is consistently unconnected, there are a few possible reasons: Faulty network equipment: If you're using a router or switch, they may be malfunctioning and your network can't connect.

Incorrect network connection settings: Your computer may not have set up a network connection correctly, preventing you from connecting to the network. Server Failure:

If you're connecting to the internet, it's possible that the server you're connecting to has failed, preventing you from accessing the network. Other reasons: Your network may have been disrupted or attacked, preventing you from connecting.

If your computer network has been unable to connect, it is recommended that you check the above reasons and try to fix the problem. If you can't solve the problem, you can consult a professional or technical support person.
