The solution to the problem that the computer cannot be connected to the Internet or the edge browser cannot be connected to the Internet

foreword

I was fortunate enough to experience three times that my computer was unable to access the Internet. I can only say that it was a long way to go to repair, so I learned from the pain and made up for it. Now I am determined to record them all. General situation: The common situations where the computer cannot be connected to the Internet are as follows:

1. Network failure: Including router, modem or network equipment failure, network line disconnection or network service provider's problem.
   Solution: Check whether the router, modem or network equipment power supply and network lines are connected normally, and check whether other equipment can connect to the Internet normally. If other equipment cannot connect to the Internet, it is likely to be a problem with the network service provider, and you need to contact the network service provider to solve the problem .

2. Driver issues: If the network drivers on your computer are outdated or damaged, it may prevent you from connecting to the Internet.
   Solution: Update the network driver, you can find and update the network adapter driver in the device manager, or go to the network adapter manufacturer's website to download the latest driver.

3. Network settings issues: If your computer's network settings are incorrect, it may also prevent you from connecting to the Internet.
   Solution: Check your network settings, including whether the IP address, subnet mask, default gateway and DNS server are correct. If you're not sure how to check these settings, try opening the Network and Sharing Center in Control Panel and selecting "Change adapter settings" to view your network settings.

4. Firewall issues: If you have a firewall installed on your computer, and its settings block certain network connections, you may also not be able to connect to the Internet.
   Solution: Check your firewall settings, if necessary, add a rule to allow networking or disable the firewall. Also, make sure your firewall software is up to date.

5. Virus or Malware Infection: If your computer is infected with a virus or malware, it may also prevent you from connecting to the Internet.
   What to do: Run your antivirus software to do a full scan and remove any viruses or malware. It is recommended to install a good antivirus and firewall to protect your computer.

6. IP conflict problem: If your computer and other devices use the same IP address on the same network, it may also cause the inability to connect to the Internet.
   Solution: Check whether the IP address of your computer conflicts with the IP address of other devices, if so, please change the IP address of your computer. You can try command-line tools such as "ipconfig" to view your IP address and other network settings.

Next, it will be explained in detail, and the specific operation method will be attached:

problems

1. Network settings

Generally, if there is a problem with the network settings, our computer will not be able to access the Internet. This is the most common reason for not being able to access the Internet. Just change the ip address. Generally, you can access the Internet after setting up, if not, then check the DNS server to see if there is a problem with dns. If so, modify the agreement on it.

2. Internet Explorer

The Ie browser can also set the ip address, so it may be that the ip address on the ie is wrong and the Internet cannot be accessed. Just open the tools on the web page to view and modify. Another way is to use software to view and repair. You can also try other browsers to see if it works.

3. Firewall

Firewall settings will affect Internet access. Some URLs cannot be opened and accessed due to firewall settings, so you cannot access the Internet. Check the firewall is not set what, and then change the adjustment just fine.

4. Network protocol

Find the control panel of the computer, find "network protocol" in the properties, check if there is any problem, then check the protocol driver, and download it again if the driver is damaged.

Phenomenon 0 black screen, blue screen, crash

  Reboot first! ! ! Restart first, the computer has a black screen of death or something, there is nothing that can’t be solved by restarting, even restarting can’t solve it, then send it to a computer store, network problems are another issue. If the computer can be turned on, but cannot access the Internet, continue reading.

Phenomenon 1 All software cannot access the Internet

If the computer network settings are wrong,

1. First, we right-click the start menu, find "Windows PowerShell (Administrator) (A)" and open it. Then enter “ping http://www.baidu.com -t”to check whether the external network is normal.

How to open as an administrator: Windows 10 desktop, right-click the start button in the lower left corner of the desktop, select "Command Prompt" in the pop-up menu, right-click to enteradministrator mode；

Note : If you can access the Internet, it may not be a problem with the network settings, but a problem with the browser itself. If it is a configuration file problem, it can also be operated through the command line, as follows:

2. Open the administrator command window (command prompt, you can search in the menu, and right click to start the administrator mode), enter: ipconfig /flushdnsand press the Enter key;

3. Wait for the prompt: The DNS resolution cache has been successfully refreshed.

4. Enter the command again: netsh winsock reset command, then press Enter;

5. Wait for the prompt: the Winsock directory has been successfully reset, just restart the computer.

Phenomenon 2 An exclamation mark appears at the wifi

It belongs to the network card problem. The driver problem of the network card and the hardware problem of the network card will cause the inability to access the Internet. Need to carry out professional maintenance, reinstall the driver and other methods.

Phenomenon 3 There is a problem with IP or DNS resolution

Check the firewall first. If the network firewall is not set properly, such as the security level is too high, it will also lead to the inability to access the Internet. Lower the security level of the firewall or turn it off directly to see if it returns to normal.
IP address conflicts lead to inability to access the Internet, open the Control Panel - Network and Internet - right-click wifi - find the IPv4 protocol, change the DNS and IP address to automatically obtain, click OK. As shown below:

Phenomenon 4 Other software on the computer can access the Internet, but the Edge browser cannot access the Internet

If the Microsoft Edge browser cannot access the Internet, you can try the following solutions:

• Check your network connection : First, check that your computer is connected to the Internet. Make sure that the network connection is stable. You can try to open the webpage with other browsers to see if you can access the Internet normally. If other browsers are able to surf the web without problems, then the problem may be related to the Microsoft Edge browser.

• Clear the browser cache : Sometimes, the browser cache may prevent the browser from loading web pages, trying to clear the Microsoft Edge browser cache may help resolve this issue. You can open the Microsoft Edge browser, click the "…" icon, select "Settings" -> "Privacy, Search and Services" -> "Clear Browsing Data", then select the type of data you want to clear and click "Clear".

• Check proxy settings : If you use a proxy server to connect to the Internet, it might be helpful to check your proxy settings. You can open the Microsoft Edge browser, click the "…" icon, select "Settings" -> "Privacy, Search and Services" -> "Proxy", and then make sure your proxy settings are correct.

• Disable extensions : Some extensions may interfere with the normal work of the Microsoft Edge browser, try disabling all extensions of the browser, and then restart the browser to see if you can surf the Internet normally.

The author installed Violent Monkey and Greasy Monkey, and the browser crashed due to the damage of the extension package. Now I have completely given up the extension package.

• Reset browser settings: If none of the above solutions work, you can try to reset Microsoft Edge browser settings to restore the browser's default settings. You can open the Microsoft Edge browser, click the "…" icon, select "Settings" -> "Reset Settings", and click "Reset".

The specific explanation is as follows:

The edge crashes can be roughly divided into two categories:
(1) Opening the flashback, or not being able to open
(2) Crashing during use.
Possible causes fall into three categories:

• Insufficient configuration, not enough for program performance consumption;
• component damage;
• compatibility.

The first way to solve the problem: to clean up your C drive, you can use third-party tools, such as EaseUS computer migration, geek and other tools.
The second way to solve the problem: the detection and repair of component damage is relatively easy.
(1) Reset the browser. Open Edge, click next to your profile picture in the upper right corner... click Settings – Reset Settings.
(2) System troubleshooting to detect problems. Start - Settings - System Troubleshooting - Other Troubleshooting - Windows Store Apps" to run. This action fixes crashes with the detection and repair capabilities provided by the system.
(3) Application repair. Start – Settings – Applications – Applications and Features – More options on the right side of Microsoft edge ┇ – Repair (Change). Specific steps are as follows:

• Make sure your browser is closed and you have administrative rights to the device. If multiple users are signed into the device, make sure to close Microsoft Edge for all users.
• Select Start > Settings > Apps > Apps & Features.
• In the list of apps, choose Microsoft Edge, and then choose Modify. If the Modify command isn't available, chances are your organization has Microsoft Edge installed and it's being managed for you. Please contact your system administrator for assistance.

There is a high probability that your anti-virus software or other tools are monitoring the browser and you just need to close it.

• If prompted: "Do you want to allow this app to make changes to your device?", select Yes.
• Make sure you are connected to the Internet, then select Repair. The fix should not affect browser data and settings.

(4) Command prompt detection. Search – command prompt cmd – right click to run as administrator – enter the following code and press Enter:

sfc /scannow

Note: This code (note that there is a space) is used to check the integrity of system files. If a problem is detected, the system will prompt and fix it. It takes a long time, so be patient.

The third way to solve the problem: If there is a compatibility problem, or a crash caused by unknown reasons, it is a problem that cannot be solved by uninstalling or reinstalling. It's big, and it's useless.

Uninstall or reinstall

To reinstall, you only need to go to the official website to repair and install again.
Uninstallation: With third-party software:geek= (need to leave a message in the comment area).
