My computer can t be connected to the local connection, what s the matter, please ask the master

The local connection can't be connected, is there a red cross on the computer icon in the taskbar? Generally, the network cable is not plugged in, and another reason is that your network card is not plugged in, or the "cat" is turned off, anyway, as long as the interface of the network cable is plugged in, the light is not on or flashing, and the local connection will not be connected.

What kind of network are you connected to? ADSL dial-up Internet access, or the unit's LAN, if it is on the unit, then there is a problem with the switch or router!

When the newly installed computer cannot access the Internet normally, the first thing to do is to re-enable the "Local Connection": double-click to open the "Computer", right-click the "Network" icon on the left, and select the "Properties" item.

In the Network and Sharing Center window that opens, click the Change adapter settings button.

Right-click on "Local Connection" and select the "Disable" item.

Next, right-click on "Local Connection" and select the "Enable" option.

Run the software, and in the main interface of the program, check the item "Disable Wired Network Cards".

Next, uncheck the "Disable Wired NIC" item.

Limited local connection means that your IP address is wrong, and the reasons for this situation I (glasses) have personally summarized that there are the following four reasons.

1. If you set the NIC to automatically obtain the IP, then you need to see if your route does not have DHCP enabled

I'm glasses, I'm sorry, add some anti-theft words, please forgive me)

2. If DHCP is not enabled for routing or modem with routing function, you can enable it, or manually configure a correct IP, subnet mask, gateway and DNS

3. If you've done both of the above and it's still useless, it's time for you to try a different cable.

The most common ones are the above three.

There is another possibility, but it is rare, and the probability is relatively small, that is, the network card chip is damaged.

Of course, in addition to the above situation, the landlord can refer to the following practices to try.

I'm glasses, I'm sorry, add some anti-theft words, please forgive me)

For example, if you have a computer in your local network that can access the Internet, and its network configuration is like this, the subnet gateway is primary) standby) Then, the network configuration of your computer can be like this.

Here it can be:

As long as it doesn't conflict with other machines, it's fine. ) subnet gateway primary).

4. If you use modem dial-up to access the Internet alone, you can directly configure your IP as a subnet gateway to do so, and don't worry about anything else.

There is a conflict of IPs,,You try to unplug all the other computers directly from your computer,,See if you can connect to it,,, and you can try to restore the router and reset it,

You right-click on the local connection - > properties - > Internet Protocol - > automatically get the IP address.

Check whether your NIC driver is installed properly.

If you are surfing the Internet at ADSL, check whether the connection to the model is normal.

Set up auto-dialing in the route.

Then enable DHCP

The computer is connected to the LAN

There should be no problem with the mouth.

Broadband dial-up is set up in the router, and DHCP can be started.

First of all, your question is unclear. Is it the small computer icon that doesn't have a local connection, or can't connect to the Internet.

If you don't have an icon, right-click on the online neighbor and select the property to see if there is a local connection. If not, the NIC does not have a driver.

If there is a small computer icon, it is a bad match if you don't even have access to the Internet. You check to see if the network cable is broken or not connected to the router.

If you're using Cat Dial-up, limited or no local connection will not affect your broadband connection. If you really don't want to make your local connection unrestricted, you just need to set a fixed IP address.

If you are using router sharing to access the Internet, you can set the IP address to automatically get the IP address.

So you can supply two computers there? If it is the main thing to give up, I have the right for you to divide an IP on the server machineI want to connect directly to the local Internet.

The other is to root the network cable by yourself.

Turn off Mao's power and turn it on again, and reconnect!

Network cables are divided into direct and cross-connected lines.

Is the network port light on? What is the hint if you can't connect?
