What are the possible reasons for not being able to access the internet?

Set the following two items.

One, DNS, I offer two.

Second, add a gateway.

The general intranet is the same, yes (

You may need to restart after you're set up.

There may be the following reasons for this:

a. System reasons:

Check whether the driver of the network card is installed correctly, and the driver of the network card is suitable for the model of your network card!

See if the Ethernet network controller has one! If there is, it may be a problem!

Reinstall the system if necessary!

Needless to say, the solution is right!

b. Reasons for network cards:

You can see that the LAN does not necessarily mean that there is no problem with the network card, and it is also possible as the brother above said!

c. It may also be a problem with the network server, the solution is very simple, you can restart all computers (including servers) on the network at the same time and let the server reassign the IP address!

Try it with their network card instead.

If you can get on it, it is bound to the MAC address firewall, and you need to find the NMS to open it.

My unit used to have a similar computer, which could not be connected to the Internet, and the machine could not receive data packets, but other computers could copy, paste and other operations on this computer through online neighbors. Your network cable is normal, so the problem appears on the network card, it should be a pin in the slot on the network card that plugs the network cable in.

1. If there is a problem with the network card: try a different network card.

2. There are too many or too few problems with protocol installation: add or remove protocols.

Does IE have a connection?

If you are using a LAN, the new machine that joins the LAN needs to restart the modem

It may be that your network card is broken, or your network card is not plugged in properly. Or maybe there's something wrong with your internet cable. That is, your double glue line is misallotted.

Maybe you don't have the money to pay for the internet."

I have helped you find the results; In general, the possible reasons for not being able to access the Internet are:1The computer does not properly install and set up a network adapter or other network device; 2.

The router or ISP is not set up correctly; 3.The computer is infected with viruses or Trojan horses; 4.problems with your computer's firewall and security settings; 5.

There is a problem with the network provider. To solve the problem of not being able to access the Internet, you can check the corresponding network equipment of the computer with the eraser code, check whether the system is infected by viruses, check whether the security software is installed correctly, if possible, you can try to restart the settings of the router or ISP, and finally, you can check whether there is a problem with the network ** provider.

The reasons why you can't access the Internet are as follows

If your home wifi, you can get bored with the Internet after connecting it before, and suddenly there is a problem of not being able to access the InternetAnd the router and the cat have been powered off and restarted, but it still can't be used after connecting to wifi....In this case, it is very likely that there is a problem with the broadband line, or the state is caused by the broadband arrears...

2. If there is no arrears, you can transfer to the manual customer service, report the fault, and let the operator arrange the staff to repair the bookPS: If you don't know how to dial up Internet access with a broadband connection in your computer, you can read the tutorial below to see the operation steps...

At this time, if the computer can access the Internet, it means that the broadband line is normal and there is no problem.

Hello dear<>

The reason for not being able to access the Internet is that the WiFi network itself has a problem, and the number of birds will cause the WiFi to be unable to connect normally, so it will not be able to access the Internet, and it will also be a slag or broadband arrears, resulting in the inability to access the Internet, so these problems will occur. Solution: You can use your mobile phone to connect to other wifi first, and see if it can be used.

If there is no other wifi can be connected, then you can let the people around you open a hotspot, you use your own mobile phone to connect to try, if you can use, then it means that there is a problem with the wifi at home, you can check whether the broadband is in arrears, or there is an abnormality, contact broadband customer service. Second: If the reason for the router is that the network connection at home is not used, it may be because there is a problem with the network cable connection, such as a failure or power outage at a node of the optical fiber, resulting in the signal not coming over.

Or there is a problem with the router, which may be overheated or damaged, resulting in signal transmission problems. Solution: Try to restart the router, unplug the network cable and plug it back in, or restore the router to factory settings, then re-dial, and re-set the wifi according to the setup wizard.

Third: If the above points are okay for other reasons, then you should consider whether it is a problem with your mobile phone or whether there is a problem with the system, which leads to the inability to access the Internet. Sometimes when you go out to connect to other people's networks, you may not be able to connect to the network, which may be due to the fact that there are more people connected, or you need to log in through the browser to register before you can access the Internet, which is not recommended to connect.

1. If you are using a home network, it is recommended to connect to other WiFi or mobile phone personal hotspots for testing and troubleshooting: 1If you are connected to other Wi-Fi facilities, 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). 2. If you are using a public network: 1

Try using it in a place with a small amount and confirm that the hotspot is working properly. 2.Please check if you need to log in through a browser** to register before you can access the Internet.

3. If individual applications cannot access the Internet: please open the settings, enter traffic management in the search box and click to enter the traffic management page, click on the application network, and check whether the individual application checks WLAN

What is the reason why you can connect to the network but can't access the Internet, the reason why you can't access the Internet may be that the broadband is in arrears, the network is faulty, and you can connect to wifi but can't access the Internet; When the network cable is damaged, it will cause the wifi to be unable to access the Internet; If you have a problem, such as connecting your phone to someone else's hotspot, but the other party turns off the network or changes the one-time data limit to 0, you will not be able to access the Internet in the first instance, and you can resume the Internet by solving the specific problem.

Summary. There are many possible reasons why the network is unavailable, including but not limited to the following:1

Network connection failure: It may be due to a faulty network device, loose or damaged cables, etc., that prevent you from connecting to the Internet properly. 2.

Network signal issues: If you're using a wireless network, it may be that the network isn't connecting because it's too far away from your wireless router or because of signal interference. 4.

Carrier network issues: Sometimes a network outage can be caused by a carrier network failure or maintenance in your area, and you need to wait for your carrier to return to normal. 5.

Software or device failure: This may be caused by a malfunction of the computer, mobile phone, router, or other equipment you are using, or a problem with software such as network drivers, operating system, etc. You can try to restart the device, check the connection line, reset the network parameters, contact the carrier or technical support, etc. to solve the problem that the network cannot be used.

It could be caused by a malfunction of your computer, phone, router, or other equipment, or a state ridge issue with network drivers, operating system backup, and other software. You can try to restart the device, check the connection line, reset the network parameters, contact the carrier or technical support, etc.

Can you add, I don't quite understand it.

The reasons why the network is unavailable may be:1Network connection failures, such as closed die equipment failures or cable problems.

2.Network setup issues, such as misconfiguration or IP address settings. 3.

Wireless network problems, such as distance or signal interference. 4.If the carrier network fails, you need to wait for the carrier to return to normal.

5.Failure of soft car parts or equipment, such as computer, mobile phone, router failure or software problems. Workarounds can include restarting the device, checking the connection line, resetting the network parameters, and contacting your carrier or technical support.
