WiFi can be used at home, but the computer can t be connected to the Internet, why

1) If it's a problem with the router, if it can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. After there is a factory reset, it can be used from the new settings (this is on the premise that the physical connection is correct).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

2) If it is a problem with the broadband itself, first directly connect the broadband network cable to test, if it is a broadband problem, contact the broadband customer service to solve it.

3) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

Use the system that comes with the system restore method:

System Restore that comes with the system: "Start" "Programs" "Accessories" "System Tools" "System Restore", click "Restore my computer to an earlier time", press Next, you will see that the date page has a dark date, that is the restore point, after you select, click Next to restore (win78 restore the system, right-click on the computer to select properties, on the right side to select system protection, system restore, follow the steps to do it, if there is restoration software, you can also use the software to restore the system).

4) If you turn off the wireless switch, it's just that, if it's a wireless connection with software, the software is not good to use, and it's normal to have problems with helium hair often, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

5) If you have any questions, please ask me.

6) The mobile phone can access the Internet does not mean that the computer will be able to access the Internet, make an analogy: a computer can go online, a computer may not be able to access the Internet when it is turned on, but it does not affect the Internet access of another computer, here is the problem of using a router to access the Internet.

Check whether there is a network or whether the network is running properly.

In many cases, if the computer is not connected to the Internet, it is not the problem of the computer, but the problem of the network itself. So let's first check whether the router, cat, and other network devices are working properly. If the network is normal, it is a problem with the computer, if the network is not normal, it may be a network line problem, it is recommended to wait for a period of time or contact the operator to solve it.

Wifi is wireless network, wireless network can be simply understood as wireless Internet access, almost all smart phones, tablets and laptops support wifi Internet access, is the most widely used wireless network transmission technology today.

Restart the computer and try it, if it still doesn't work, plug in the network cable again and check whether the network cable socket light of the computer and router is on.

Power off the router and power it back on every minute to see how it goes.

1. There may be a problem with the IP of the computer. Press Win+R, type "netsh winsock reset" and restart the computer to see if it can connect to WiFi.

2. It may be that there is a problem with the wireless network driver of the computer, which causes the computer to be unable to connect to the wifi normally. First, right-click on the computer, click on the device, then click on the device manager, and then find the network device, check if there is an abnormality in the wireless network, if there is an abnormality, then you need to reinstall the network driver. After installation, go and reconnect.

3. Or turn off the router, then wait a few minutes, restart the router, and then reconnect to the wifi.

You can try to set the IP of your computer to a fixed IP!
