How to fix error: Problem with DNS Cache

Dear Kevin,

Hello! Welcome to the Microsoft Community.

It looks like you are experiencing a DNS cache issue after Windows Update, which results in WiFi connecting successfully but not being able to access the Internet. I understand your feelings and I will try my best to help you.

I understand that you have tried to flush the DNS cache, but the problem still exists. If you have tried the steps provided below, please ignore them directly.

• Search for "cmd", run "Command Prompt" as an administrator, and run the following commands. One line at a time and press enter: ipconfig /release ipconfig /renew ipconfig /flushdns netsh int ip reset netsh winsock reset ipconfig /all
• Modify the DNS address. The problem that you cannot connect to the game server may be related to your DNS address.

1. Open "Control Panel" > "Network and Internet" > "Network and Sharing Center".
2. Click "Change adapter settings".
3. Right-click the network adapter you are using and select "Properties".
4. Double-click "Internet Protocol Version 4 (TCP/IPv4)".
5. Select "Use the following DNS server addresses" and enter the following DNS servers:

• Google DNS:

Preferred DNS server: 8.8.8.8

Alternate DNS server: 8.8.4.4

• Cloudflare DNS:

Preferred DNS server: 1.1.1.1

Alternate DNS server: 1.0.0.1

• Microsoft DNS:

Preferred DNS server: 4.2.2.1

Alternate DNS server: 4.2.2.2

• Clean the Host file and navigate to the following path: C:\Windows\System32\drivers\etc\hosts.

Select the hosts file, then right-click and open it in Notepad. Delete all the contents and select Save.

To prevent accidents, you can back up a copy before deleting it and save it somewhere else, such as the desktop.

• Change the Wi-Fi channel. Users with similar problems have reported that changing the WIFI channel can solve this problem. It can help avoid interference with neighboring networks, especially in areas with crowded Wi-Fi networks. Changing the Wi-Fi channel is usually done in the router's settings. Access the router's management interface, find Wi-Fi settings, and change the Wi-Fi channel. You can also consult the router's service provider.
• Check firewall and security software

Make sure the firewall or security software is not blocking the network connection. You can temporarily disable the firewall for testing.

Disclaimer: Temporarily turn off antivirus protection. However, keep in mind that if you do so, your device may be vulnerable to threats. So please turn it on immediately once issue fixed. 

• If the above steps don't work, consider resetting your network settings, which will remove all network adapters and reset all related components.

1. Open Settings > Network & Internet.
2. Scroll to the bottom and find Advanced Network Settings.
3. Click Network Reset.
4. Follow the prompts to restart your computer.

- I noticed that this problem occurred after an update, and it is possible that the latest update caused the problem. You can consider rolling back the update. Go to "Settings", "System", "Recovery" and see if there is a "Go Back" option. If there is, it should be possible to return you to the state before the update. Again, any changes you made in the meantime will be reverted.

If the option is gone, it is because it is usually only available for about ten days. Try uninstalling the latest few updates (based on the date), go to "Settings", "Windows Update", "Update History", "Uninstall Updates", uninstall the corresponding updates and remember the corresponding KB number. If the problem persists after uninstalling, consider downloading these updates again.

Search and download the corresponding updates from here: Microsoft Update Catalog
