What is the reason why my computer is not connected to the Internet?

If you can't connect to the Internet, you can take a look below, if you can connect to the Internet, please ask me.

If it is a broadband problem, please call the broadband customer service ** and ask them to check for you. If it is a router problem, please call the brand router customer service for **consultation, they have **guidance.

1) 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.

2) 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. In there is a factory reset, from the new strict according to the manual settings can be used, I don't understand, it is not recommended to set it at will (this is under the premise of the correct physical connection, sometimes the router is slow or failed to find the IP address, not that the router is broken).

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.

3) If you turn off the wireless switch, turn it on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, 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.

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

Taking win10 system as an example, the main reasons are:

1. The computer shows that the network connection is not available, it may be that the network is disabled on the computer, the user can "open the network and sharing center", and then select the "change adapter settings" option, and enable the disabled "wireless network connection" in the change adapter settings interface.

2. If the network used is unstable, it will also cause the computer to show that the network connection is unavailable, you can plug and unplug the power of the router and try to reconnect.

3. It may be that the network operator is faulty, resulting in the computer showing that the network connection is unavailable, you can contact the operator's customer service staff to inquire about the fault.

4. If there is a problem with the network cable connected to the computer, it will also cause the computer to display that the network connection is unavailable, and you can replace the network cable with a new one, so that the problem can be solved.

5. If the network is in arrears, then after the computer is connected to the network, the network connection will also be unavailable, and only need to make up the payment in time, so that the network can be used normally.

1. Look at the indicator light to determine whether it is a problem with the external line or optical modem.

If you have a lot of wifi"Connected but unable to access the internet", the first time to look at the light of the modem, to see if the light of the light cat LOS light turned red, or red and green. If there is such a situation, it is likely to be due to the external line or the reason of the optical modem itself, just dial the corresponding operator** directly (China Telecom 10000, China Unicom 10010, China Mobile 10086) because you personally cannot solve this problem.

Second, in addition to the external line problem, it may appear in the router itself.

If dial-up routing is enabled on your modem, it may also be that the IP address of the modem and the IP address of the router conflict may cause Wi-Fi"Connected but unable to access the internet"。You need to change the IP settings of the router to an IP, generally the IP address of the router is, this is what you can try to change to this IP address.

3. Interference by the neighbor's WiFi channel.

Nowadays wifi will face a lot of interference, the biggest source of interference may be the neighbor's wifi, the same channel and adjacent channel wifi can cause strong interference to your home's wifi. In addition, Bluetooth also works in the unlicensed spectrum and can also interfere with your wifi. From the beginning, the router can basically solve this problem, or change the router.

The computer is connected to wifi, but it shows that it is not connected to the Internet, you can check your router, it should be a router failure that will cause it to be unable to connect to the Internet, so it can not be used normally when connected to wifi, so it cannot be connected to the Internet.

The computer is connected to WiFi, but the connection with the router is established, and the network at the front of the router is not successfully connected.

If the computer is connected to wifi, it can only mean that the router is working normally and connected to the computer normally, but the router does not provide network data transmission, it is recommended to check whether the optical modem is working normally and provides network signals.

Why does my computer show that it is not connected to the Internet when it is connected to WiFi? I think that in general, the computer is connected to wifi but does not show that it is connected to the Internet, probably because your operation steps are incorrect, or because of arrears.

This is because wifi is connected, but the network is not available. Most of these are due to network connection issues, so restart the router and try it.

Generally, there is a problem with the router networking, which does not affect the computer to connect to wifi

It could be that there is a problem with your wifi, check your wifi

Check whether the external network is working.

Usually, the computer is unable to connect to the Internet due to problems with the network operator. After a while, it will connect automatically. You can check the status of the indicator light on your broadband modem.

If the traffic light keeps flashing or doesn't come on at all, it's not a computer. The problem is that the network signal does not reach the computer. You can call your network operator (China Telecom or China Unicom) to resolve the issue.

Usually, the city resolves the problem within 24 hours. If the signal light of the broadband modem is always on, the network is normal. Please look for the cause of the problem with your computer or router, switch, network card.

Summary. Please check that your network connection is working and make sure you are connected to the correct wireless network or plugged in the correct network cable.
