There is no problem with the computer network cable, but you can t get on the Internet, you can get

If your computer system is fine, change the network card.

Summary. If your computer can access the Internet normally with a cable in a certain place, but you can't connect to the Internet in another place, it is likely that your computer has been set to bind an IP address to a MAC address before. In this case, just unbind it and you will solve the problem:

PS: If this doesn't work, it may be that the router has set up MAC address filtering, in which case you have to add your MAC address to the whitelist in the router settings, or reset the router directly.

The way to detect the quality of a wired network card: run cmd, enter ping, press enter, and see if there is a loop, if there is a loop, it is good.

Problems with other hardware: try to change the network cable, try to change the network port...

The computer can't get on the Internet after plugging in the network cable in a different place.

If your computer can access the Internet normally with a cable in a certain place, but you can't connect to the Internet in another place, it is likely that your computer has been set to bind an IP address to a MAC address before.

The above is the relevant information we have found for you, I hope it will be helpful to you. 

That is, your password or username is wrong, take a closer look to see if it is filled in correctly, if the password is missing, call 10000 to reapply to retrieve the password.

This situation may be caused by a faulty network cable and poor contact.

There is also a possibility that there is a problem with the network port on your computer, either the contact is not good, or the network port is broken!

It is recommended that you unplug and unplug it a few more times to see if it will be linked, but it can't be like this: click the right mouse button on my computer -- manage -- device manager -- network adapter -- find the corresponding network card driver and click the right mouse button -- properties -- advanced -- connection speed and duplex mode -- the drop-down list on the right is changed to -- 10mbps half-duplex, click OK, if the network is connected, it proves that it is a network cable problem. If you can't test it, you need to use tools such as a tester.

If the computer network port is broken, it is recommended that you go to the computer city to buy a PCI network card, which is very cheap.

The same network cable is changed to another computer, and the possible reasons for not connecting to the Internet are as follows:

1. The router is bound to MAC, so that if the network card is inconsistent, the computer connected to this network cable will not be able to access the network, unless the router is unbound.

2. After eliminating the reason for MAC binding, the second computer cannot connect to the network, and the fault point is in the computer itself, such as network card driver problems, system problems, etc.

How your line is pulled. Is it ** line in the "broadband cat" computer.

First, check whether the NIC is driven, and then check whether the IP address is correct

I've had this problem with my router at home before, and it's very old!

It's caused by the network not working.

It is estimated that it is a problem with the DNS configuration, and it is recommended to initialize the router and reset it.

Or manually specify a DNS server to try.

On the computer side. Not fully automated!

Troubleshooting the problem of computer network card failure is generally a problem with the IP setting of the computer. Here's how to fix it:

1.Click Network on the right side of the taskbar, Properties;

2.Click "Change adapter settings", click Properties;

3.Click "Local Connection" and click on the local connection properties;

4.For point-level TPC IP protocol, click Automatically obtain IP address and DNS, and click OK.

It's their problem, your machine can't be on, while other machines can, it's usually they who limit you.

You can find them, or change the MAC address of your own machine.

You can change the MAC address first, one is to change it on the motherboard. The second is the following operation, right-click my computer Properties - Hardware Device Management - Network Adapter Network Card Right-click Properties - Advanced There is a value on the right side of the network address, and write an address that meets the rules in the value OK, it is estimated that it can be solved.

Change the MAC address of the NIC. It is to change the MAC address of your computer's network card to the MAC address of the computer that can access the Internet. First of all, you can find the physical address on the computer with Internet access, under the command line interface, under ipconfig all, and then find the physical address, which is the network card address.

Then, on your computer, on NIC Properties, Configuration, Advanced, find the NIC address item, modify. That's it. If your computer's network card does not have this item.

Baidu, it is easier to find a software that modifies the MAC address of the network card. Foolish.

It can basically be determined that it is his problem, and it is okay to leave the router on for a long time.

It should be his problem, let him leave the router on and not turn it off.

You first determine whether the router is open DHCP free acquisition or disabled, if it is on, you need to set your local connection to automatically obtain IP, you need to set your computer IP and set the network management subnet mask, etc., this needs to find the administrator of the route.

If you can't go up, just see if the router has an IP MAC binding If you have it, you probably have to specify your IP Otherwise, you won't be able to get on it.

It's all done, and it still can't go up, so reinstall the system, replace the network cable, check the network connector (you can find a line tester for these two items later, and test it to know if it's damaged.) The three items are in no particular order, which is easier to come first.
