What s the deal with the computer not being able to access the Internet, and what is the matter if t

This needs to set the IP address of the network card, you ask what the IP gateway of your neighbor is and then remember to set the DNS If the computer does not have the network card after repair, you have to right-click on the online neighbor, properties, and then see if there is a local connection, if there is no local connection, it means that your new motherboard does not have a network card.

Oh ,,The network card is more likely to be broken, change a network card, that is, about 20 yuan, you should access the Internet through routing, and the neighbor has nothing to do with it, unless the neighbor changes the settings.

It should be a problem with the NIC driver.

You can consider reinstalling the NIC driver

You connect locally to press to disconnect.,Press connect again to see.,It's not good m for me.。。。

The computer cannot connect to the Internet, and the reasons may be as follows.

First, the software server failure causes the software to be unable to connect to the Internet, which can only be networked normally after the official repair is completed.

Second, it may be caused by the instability of the local network, try to power off and restart the modem and router, and it is also possible that the device often does not shut down and causes it to crash.

Third, there may be a problem with the network configuration of the system, which can be fixed by command.

netsh int ip reset

netsh winsock reset

Restart your computer, then open the software to see if you can use it online.

Fourth, it may be that you have LAN enabled**, just turn it off.

Open the Control Panel, Internet Options, Connections, LAN Settings, Server Settings, and remove the checkmark below, as shown in the image below.

Check whether the broadband account password is correct, if the password is incorrect, it is impossible to connect to the Internet, if you accidentally forget it, you can call ** to the customer service to cancel the rent;

Check whether the wireless password is correct, if you are using a wireless network, you should check whether the password of the wireless network is correct, similar to the above;

Check whether the modem is damaged, if the modem is damaged, the only way to find someone to repair or replace it is to find someone;

Check if the wireless router is damaged, if not, you can see if there is a problem with the router's settings;

Check whether the network cable is plugged in or damaged, sometimes the computer is unable to access the Internet when the network cable is loose or bitten by mice, plug in the network cable or replace the new network cable after checking the problem;

The old network card driver will also cause the computer to be unable to access the Internet, click on the network card driver to update, so that it is kept in the latest state, different models of notebooks can go to their respective official websites**;

Check whether the network card is damaged: the network card is a necessary hardware device for Internet access, without the network card we can not link the network, the use of wireless network card to access the Internet friends can detect whether it is the wireless network card damage caused by the Internet can not go online;

If none of the above situations can be solved, we can consider calling ** to customer service, and if necessary, the customer service will notify the maintenance personnel to conduct on-site inspection and maintenance.

Note: Make sure that the broadband or wifi connection can be used normally.

It really doesn't work to reset the router, or change the network to see if it can be connected, if it still can't, it's a problem with the computer itself.

There are many reasons, you should buy a book like this and study it well!

There may be a problem with the network connection, and you still have to find a professional master if you have something.

There are several reasons why you can't connect to the Internet

1. The NIC driver is not installed or installed incorrectly;

2. Due to networking software, the parameter setting is incorrect;

3. Hardware problems, network cards, network cables, switches, routers, cats, etc. are damaged;

4. Network setting problems;

5. Other incurable diseases.

Ways to solve the above problems:

1. The NIC driver is not installed or installed incorrectly;

Answer: If the NIC driver problem is relatively simple, we only need to install a network card driver, and then use the network card driver to detect the network, and it will be OK after automatic repair.

2. Due to networking software, the parameter setting is incorrect;

3. Hardware problems, network cards, network cables, switches, routers, cats, etc. are damaged;

Answer: If we have tested the above two software problems, if there are no problems, we have to consider the hardware problem. The first thing we have to do is see if there's a problem with the modem, or what we call the "cat".

4. Network setting problems;

There are many reasons that can cause the computer to fail to access the Internet, and we can judge the cause of the failure in the order of hardware first and then software.

First of all, check if there are any reasons for some low-level errors, such as adsl not open, whether you forgot to dial, etc.

If you can be sure that you have not made low-level mistakes, you should check whether the network cable connector is loose, whether the line is normal (when some**line fails, it can still be played), whether the ADSL indicator is normal (most ADSL should have 3 lights on when there is no dialing), and whether the network card is loose.

If you don't find a hardware problem, it's time to check the software. You can check whether the NIC driver is normal; Try re-establishing a new dial-up connection; Sometimes QQ can be used normally but the web page cannot be opened, which is caused by browser failure or virus software.
