What should I do if the two computers can t connect to the network cable? Do yourself a favor

First of all, determine whether the network card driver is installed with a heavy *** card driver.

If it doesn't work, reduce the speed of the network card by 100 to 10? If it doesn't work, see if the crystal head is loose and change the crystal head.

If it doesn't work, use a line tester to see if it's a wire problem.

If it hasn't been resolved.

So. Smash the computer.

1. Connect the two computers directly with network cables.

2. Set the LAN IP addresses of the two computers.

Set the IP address of PC 1.

The IP address of the first computer.

Set to: , subnet mask.

Set to: as the default gateway.

Set to: to prefer DNS server.

Alternate DNS server setup.

For: Empty. The subnet mask is set to the default gateway to : and the standby DNS server is empty.

Note that when the IP address is set, the default gateway of the two computers should be the same, this * can be changed at will, but to ensure that between 1-254, the last digit of the IP address must be different, and it must be one of 1 254, the reason is that the network segment of this mask, the IP with the last digit of 0 is the network address of the network segment, and the IP with the last digit of 255 is the broadcast address of the network segment, which cannot be assigned to the host and cannot be selected.

3. Set up network discovery and disable password protection.

On PC 1, click to open the Network and Sharing Center.

Change advanced sharing settings – the first three clicks are on, and the last tap is "Turn off password-protected sharing".

Computer 2, the operation is the same as above.

4. The ping command of cmd is used to test whether the two computers are connected correctly.

In the first computer, click Start Menu, type cmd, and press enter twice, the command interface appears, enter.

If there is a prompt with three lines of multiple numbers on the ping, it is connected.

5. Set up a shared folder.

Take the example of accessing a second computer with the first computer, in the second computer.

Select the folder you want to share, right-click, Properties--- Share --- Advanced Share.

Hit in front of sharing the folder and select Permission is everyone.

6. Access Shared Folders.

Now you want to access the shared folder on your second computer.

On the first computer, press the Windows+R keys to come up with the command line. Input.

This brings out the shared folder.

Click here, there will be a message with limited access, in the second computer, right-click on the shared folder --- Share --- Share.

Click on the small triangle, come out of everyone, click on add, and change the permission to read and write.

If you access it again, you can access it normally, and you can also copy and paste it.

7. After the transfer is completed, turn off sharing.

For the security of your computer, you need to turn off the computer that has been transferred.

The operation is as follows, that is, the reverse operation of step 3, and restore the original settings.

Pro, two computers are connected to the network through a network cable with a signal, it is recommended to add a switch or router, connect the network cable with a signal to the router, and then connect two network cables from the router to the two computers to share the network, so as not to replace the past.

Ethernet cables cannot be connected in parallel like light cables. If you want to connect the Internet to the Internet, you must buy the simplest router to connect the network cable to the computer. The simplest router costs only a few dollars.

Not sure what I mean by switching a network cable? If two computers share a network cable, use the Internet alternately. That's no problem. As long as both computers have internet access.

1. Right-click the network icon on the desktop of win10 system and select "Properties", as shown in the figure below.

2. In the Network and Sharing Center window, click "Set up a new connection or network" as shown in the image below.

3. Select "Connect to Internet" in the Settings Network or Network dialog box, and then click Next, as shown in the figure below.

4. Click Set up a new connection in the Connect to Internet window, as shown in the figure below.

5. Then select "Broadband PPPoE", as shown in the following figure.

6. Finally enter the ISP information provided by the Internet service provider, both and the password. Then click "Connect" as shown in the image below.

7. After clicking on the link, the system prompts that your Internet connection is being created, wait a while, and the broadband connection will be set.

Once connected, the Network & Sharing Center will display the wired network you just set up.

8. After the broadband connection is successfully created, you can see the broadband connection icon we just created in the network connection, right-click on the broadband connection, and select "Create shortcut" to facilitate us to quickly connect to the Internet in the future. This is shown in the figure below.

If multiple computers are connected to the same network cable, there may be the following reasons: IP address conflict: each computer needs to have a unique IP address to connect to the network, if multiple computers use the same IP address, then there will be no connection to the network.

The workaround is to set a unique IP address on each computer. Network Fails: If a network device, such as a router or switch, fails, it can cause multiple computers to be disconnected.

You can try restarting the network device, and if the problem persists, you may need to replace the faulty device. Incorrect network configuration: If the network is not configured correctly, it can also cause multiple computers to be unable to connect to the network.

You can check the network configuration to make sure that each computer's gateway, DNS, etc. settings are correct. Insufficient network bandwidth: If the network bandwidth is insufficient, you may not be able to connect to the network when connecting multiple computers at the same time.

You can try upgrading your network bandwidth or controlling the number of computers connected at the same time. Firewall or network security settings: If the firewall or network security settings are too strict, it will also cause the computer to be unable to connect to the network.

You can try adjusting your firewall or network security settings, or turn off your firewall and try to connect to the network again. It is necessary to investigate the specific situation and find out the problem before taking corresponding measures.

Summary. 5.Network Setup Error:

If your computer's network settings are incorrect, such as the gateway or DNS address settings are incorrect, it may not be able to connect to the network. You can check your computer's network settings and make the necessary changes. If you are unable to resolve the issue, contact your network administrator or technical support for assistance.

What is the reason why the network cable has the Internet but several computers cannot connect to the network at the same time.

Kissing can be caused by several reasons:

1.A faulty router or switch: This can cause multiple computers to be unable to connect to the network. You can try restarting your router or switch and checking that their lights are getting bad. <>

Smile quietly] <>

2.DHCP Service Pin Breaker: If your network uses the Dynamic Host Configuration Protocol (DHCP) to assign IP addresses, then if the DHCP server fails, multiple computers may not be able to connect to the network. <>

<>3.IP address conflict: If multiple computers use the same IP address, they may interfere with each other and make it impossible to connect to the network. You can try manually changing the IP address of one of your computers to fix the Sail issue. <>

<>4.Firewall blocking connections: If you have firewall software installed on your computer, it may prevent other computers from connecting to the network. You can try temporarily disabling the firewall and then reconnecting to the network. <>

Summary. 1.There is a problem with the network cable interface

Check whether the network cable interface is in good contact and whether the interface is damaged; 2.If there is a problem with the network cable: check whether the network cable has broken cores or disconnected wires. 3.

If there is a problem with the NIC driver: Check whether the NIC driver is installed correctly and whether it is updated. 4.There is a problem with the network settings:

Check whether the network settings such as IP address, gateway, and DNS are correct. 5.If there is a problem with the network environment: check whether there is interference in the network environment and whether other devices affect the network connection. 6.

There may be a problem with the Escort router, and you may need to reset the router or check the settings of the router. In addition, it may be that there is a problem with the network settings of the computer, and the residual shooting can try to check the network settings and firewall settings of the computer to ensure that it can communicate with the router normally. There is also the possibility of a network failure, which can be resolved by contacting the network service provider.

No, only one dial-up, it is recommended to use a router (modem), or make a **.

Use the router, connect to the line, and set a network segment with the IP address.

What's the problem? I can't tell. Buy your own router and go.
