If the computer can't get into the main router, use the mobile phone to go wirelessly, if all can't get in, that is, the router is in a dead state, press the router reset hole, and then use the address and account behind the router to reset it.

Change the address of the computer to static, fill in the address, subnet mask, gateway, DNS, if you don't know, go to other computers to see, only the last digit of the IP address is different.

First of all, make sure that the cat or router can surf the Internet normally. There is Wi-Fi, so you can connect to the Internet with your mobile phone. If you don't have a network, reset your router, or have a network warranty.

If there is a network, test the network cable socket on the wall to see if the network cable is passable, you can disassemble the wall plug, and the network cable connection method is wired according to rule B. The other end should also be consistent with this end. If there is a network cable tester, it is best to test whether the cable is passable.

If not, look at whether the other end is connected to the router or the cat. Check what the default NMS IP address is. For example, the common one is to confirm that the network card driver is ready, the keyboard win+r key, bring up the running window, and enter cmd enter.

If you type ping -t ping on the keyboard, the gateway will not work. If it's different, reconnect the wall plugged wire!

Open 360 Security Guard, enter the function encyclopedia, find the first aid kit tool for network disconnection, and use it to diagnose and repair it.

The cat has a problem connecting, or is itself an invalid network.

Start the Control Panel.

Control Panel system.

System Hardware Device Manager.

Network adapter Right-click one of the network cards to deactivate (do not uninstall it, otherwise it will be automatically installed after booting).

Update the driver for the network card.

The desktop NIC does not recognize the solution 2:

Is it a red cross or a yellow exclamation mark? If it is a red cross, it is recommended to check the hardware, such as network cables, network cards, etc., if it is an exclamation mark, then check the network, use 360 to repair it, whether it is a DNS error, etc., check one by one, it should be solved.

The desktop NIC does not recognize the solution 3:

1.Confirm the network cable link and check whether the network cable indicator is flashing on. If it doesn't blink and look at the modem or switch light is flashing, the easiest thing to do is to reboot it.

2.Go to the DOS command prompt window by going to Start-Run-cmd, ping the gateway, and check whether the LAN is smooth. If the network is not available, you can enter ipconfig renew in the DOS command prompt to try to refresh it.

View the computer IP and gateway via "Start-Run-CMD", ipconfig).

3.If there is no IP in step 2, right-click My Computer - Management - Device Management to see if the network adapter is booted and right-click to boot if it is not. If you have a yellow exclamation mark or no network adapter, try reinstalling the driver.

If the reinstallation still persists, you can try to connect to another network environment to determine whether the network card is broken.

4.If it is a LAN of a cell, you can contact the administrator to learn about the IP allocation. If it is not a cell area network, contact the network operator.
