If you change computers, you can t access the Internet, what s going on?

All of the replies below are just valid if your network cable makes sure there are no problems:

1.First of all, look at whether your routing settings are correct, there is a security setting in the security settings of the route, and cancel all the firewall settings. If you don't know how to set it, restart the route.

2.You can try whether your notebook can hang QQ, if you can hang QQ but can't open a web page, we can go to the Internet neighbor to set up your own IP and DNS service code, these two are best if you know, you can check if you don't know. Input—ipconfig all

Then you can see that you can enter it manually by yourself or you can select it automatically.

3.If you can't hang QQ, and the route is set correctly. You directly use the network port to look down, don't use the route, see if you can access the Internet, if you can, that is, your route is not set correctly, if it doesn't work, you can see if the network card of your laptop has a driver.

If the network card is also driven, it may be that there is a problem with your laptop's network port.

It must be a problem with the notebook Detox first If it's not a virus It's the system settings DHCP automatic service is not open Whether the network card is turned on Turn off the wireless network card.

Check to see if your home router has MAC address filtering set up on it, if so. That's definitely not going to go up. In addition, there is an advanced option to set the IP address on your laptop. See if you have set up multiple IP addresses.

Is it the IP binding that you set up on the Internet?? You can only use one IP address to access the Internet??

You set your laptop IP to try it out with another one.

It is okay to change the computer, that is, there is a problem with the computer, which includes: system, network card driver, network card failure, and settings.

If it is a network cable or network problem, then it has nothing to do with the computer, if there is a problem with your computer hardware, then you can change a network card.

You can get a new computer, and it's usually easy to get online. It's usually easy to connect to a new computer. However, if some settings are not right, even a new computer will not connect.

Therefore, the most important thing is to see that the Internet access settings in your computer are correct.

1. Unplug the network card, sweep away the dust and polish it.

Goldfinger. Plug it back in and try to plug it in tightly;

2. Inspection. NIC driver.

whether something went wrong;

3. Set up the network again and set your IP to be obtained automatically;

Fourth, if the above methods do not work, see if the network card is broken, and try to change the network card.

There are several reasons why the computer is not connected to the Internet, if you use wifi, check whether you have logged in to the router, and then right-click on the network icon, click on the troubleshooting, the system will give the answer, the software problem is repaired by yourself, and the hardware can only be repaired or replaced.

If the computer is not connected to the Internet, changing the computer can prove that there is a problem with the network of the first computer, which may be that the network protocol has not been installed, or the network card driver is not played, or there is no network card.

That's the problem of computer system settings, follow the network setup tutorial to set it up again or reinstall the system and then connect to the network.

If the computer can't be connected to the Internet, you can fix it with 360 security guard, and the function of 360 is still quite large.

That's a problem with your computer, not the network.

You still can't solve the problem that the computer can't be connected, it can only mean that the B computer is normal. And your network is normal.

Enter the webpage to check the router, check the connection, and see if it's a network problem or a computer problem.

As long as you see that you are not in an environment, if you are, it is useless to change the computer, if you are not there, it also depends on your environment, if there is no network, then this computer is also not possible, if there is, this computer can. If you don't have a second computer, you can add a network for yourself (

I don't know if you are a laptop or a desktop, it may be that there is a problem with the network card, there is no network driver, and you need to fix the missing driver wizard.
