7. After restarting, open the web page, and the optical fiber user can directly log in to the web page and enter the password of broadband to access the Internet.

You can use your mobile phone to see if you can connect to wifi first. If you can, it's a computer problem. Try unplugging all the computers. Turn it back on

The computer network icon shows the connection, which can only indicate that the network card has been connected to the switch or router and other settings, and can only be counted as a successful LAN connection.

It may be that the data sent is not received, to see if your network connection sign two lights are on, the first is to send data will be on, the second is to receive data will be on, you can also click to see if the received data is 0, if it is 0 then there may be a problem There may be a network traffic jam, there may be a problem with the computer, please dear!

You unplug the power cord from the back of the router and after 2 minutes it appears to be plugged in.

It could be a bug with the DNS cache.

There is a solution for two rough wax species.

Like what. <>

It's OK to have a physical connection, but not an internet connection.

Your display is normal.

Dear, I'm glad about your problem, restart the router first, it may be caused by the router's feigned death. Another possibility is that your area is possible. There is a broadband project overhaul. This is just waiting for the fix to be completed.

The network shows that it has been connected, but it can't go to the Internet, this statement itself is somewhat contradictory, don't think that the Internet is just to use the browser to browse the web, this is only a part of the Internet, as long as the network is connected, it means that you can already go online, you mean that you can't use the browser to surf the Internet. When such problems occur, they are usually caused by the browser itself. It's also possible that some security software prohibits the browser from accessing the Internet.

It's also possible that if you're using a third-party browser, the system firewall will most likely block that browser from connecting to the Internet.

The computer has a network but can not access the Internet, we have to analyze the cause of the failure, first of all, it is certain that there is no problem with the local area network, the model also exists, mainly to solve the computer settings or external network problems, you can plug the network cable directly into the laptop to set up, if the laptop can access the Internet, it proves that there is no problem with the external network cable, but the network set by the computer is not right, we directly enter the setting world through **, and set up the network on it.

To check whether the problem is caused by the missing driver of the wireless network card, the detection tool uses the "Driver Genie". Open, switch to the "Drivers" tab, and see if there is a wireless card driver. If not, you'll be reminded to install the driver at the top of the "Drivers" tab.

You can install its recommended wireless LAN driver.

It may be that your LAN has been infected with the ARP virus. You can turn on the ARP firewall in the antivirus software and restart the computer.

If you have a hosts file set in your computer, then it will also cause you to be unable to access the Internet even if the network connection is normal. Let's try to clean up the contents of the hosts file.

Here you can also check whether there is a problem with the network card driver or network protocol.

If you are not familiar with the above operation methods, then you can use the network repair in the antivirus software to fix it.

To check whether the network is running normally, we first check whether the network devices such as routers and cats are running normally, and whether the indicators are normal. If the network is normal, it is a problem with the computer; If the network is not normal, it may be a problem with the network line, contact your network operator to solve it.

The reason why the computer is not connected to the Internet and the network is not connected.

1. It may be a hardware problem, such as wireless network cards, routers, and computers, which may cause the network to be unable to connect.

2. The wireless network is not on. In order to save power, many notebooks are designed with a wireless network switch, and it is turned off by default, and you need to turn it on when you want to use it.

3. If the wireless network driver of the notebook is deleted or damaged by mistake, it will also cause the wireless computer of the notebook to be unable to connect.

4. The wireless service is turned off and needs to be turned on manually.

Can connect to the router but can not access the Internet, it may be that the router to the modem is not well connected, or it may be that the modem to the local end is not well connected, check the connection between the router and the modem, restart the router and the modem, after restarting still can not access the Internet, call ** to the broadband customer service for repair.

Connecting a computer to the Internet does not mean that you can access the Internet. Only when the LAN is normal, the external network equipment is also normal, and only when the two conditions are met can the Internet be accessed. If you cannot access the Internet, you can ping the gateway to view the devices on the Internet.

If you have an internet connection, you don't necessarily have access to the Internet.

Please reset the network settings of the system first, and then repair the system to see if it can be restored.

I unloaded the 360 family bucket. Then, when uninstalling, choose to restore the previous settings. In fact, the win10 security software itself is sufficient. General household. No third-party security software.

If it is a brand machine, there will be a one-click recovery function of the manufacturer, and the system can be restored with a one-click recovery, and it can be completely restored to the complete, fast, non-toxic and clean state of the system when it first left the factory.

If you are assembling a computer, you can only solve it by reinstalling the system.

The easiest way is to reinstall the driver of the network card, if it doesn't work, you can consider reinstalling the system.

Is this question easier! I'm telling you how smart computers are today! The problem you said may be a system problem, you can restart it, try it yet, you can only reinstall the system! You try it!

First, try to see if a different network can connect. If the password is incorrect, delete the network and enter the correct password. If you can't connect, use the system's own tools to fix the problem.

Your computer has a network, but you can't access the Internet, maybe your network capacity is not large, what kind of broadband do you run at home? Now you're doing something to delete that software and hardware, and as a result, you delete the one that goes online on the computer, right? Got it wrong, right?

Uninstall 360 thoroughly, then check it with the cleaning software that comes with your computer, and finally restart your computer.

Open 360 Security Guard, enter the function encyclopedia, find the first aid kit tool for network disconnection, and use it to diagnose and repair it.

Poisoned, use your anti-virus software to kill it, or if it's useless, redo the system.

The system is fully anti-virus. Check your computer's network IP settings. Then see how Network Diagnostics prompts.

1.If connecting to other wifi is normal(1) please do not stay away from the router; (2) Please check whether the broadband account expires, restart the router and restart the phone before trying; (3) If the router has been set to the blacklist and whitelist, you need to check whether the MAC address of the mobile phone is added to the router, if the router does not set the blacklist and whitelist, please power off the router and restart the attempt. 2.

If you can't connect to other WiFi, you can't get online(1) Please turn on the WLAN switch again, and try to connect; (2) It is recommended to search for and restore the network settings in the settings, and restore them according to the on-screen prompts. (Note: This restores the Wi-Fi, mobile data, and Bluetooth connection records and deletes the Wi-Fi and Bluetooth connection records).

Use the elimination method to check the network equipment first, then check the computer network card, and then check the network cable with the network cable.

The problem of computers not being able to access the Internet is more complicated, and the following categories can be summarized in general:

1. Broadband failure.

There are many broadband faults, such as arrears, external network failure, broken cats, wrong connection of the home line, etc.;

2. Intranet failure.

Such common ones are broken network cables, cats or routing failures, network interface connection errors, crystal head virtual connection, etc.;

3. Computer hardware problems.

For example, the network card is broken, the network cable is not connected, the network cable is wrong, etc.;

The above part is basically a problem of hardware, and then a problem of software;

1. Computer poisoning. Many computer viruses can affect the Internet, especially in the local area network, and the poisoning of one computer may cause the entire network to be paralyzed. Most of the symptoms are that after a computer is turned on, all the computers have a slower and slower internet connection until they can't access the Internet.

In this case, it is enough to do a good job of checking and killing computer viruses, and pay attention to whether the USB flash drive carries viruses.

2. There is a problem with the NIC driver. In many cases, the NIC driver is installed incorrectly or the driver is not installed, and other reasons will cause driver problems. For example, whether the driver is faulty or poisoned due to hard disk damage, or whether the driver is not installed at all, etc.

Usually reinstalling the driver will solve most of the problems.

The first is that the IP address automatically assigned by the DHCP function of the router is wrong, and no IP address is assigned, or there is no redundant IP address allocation in the address pool, and the DNS setting is wrong. In this case, you can check the DHCP settings in the router and reset it.

The second is to manually modify the IP address or DNS of the network card, the IP is not in the same network segment as the IP in the network, or the DNS error can lead to the inability to access the Internet, the solution is very simple, as long as the wrong IP address or DNS can be corrected. Usually the router will automatically assign an IP address, which is the function of DHCP, in this case, you only need to delete the IP and DNS address in the network card.

The above is a common problem that the computer cannot access the Internet, and the specific problems need to be analyzed specifically, so I can only briefly introduce them.
