How to Fix Internet Connection Problem for Windows 10 Users?

In this article we will show you how to fix internet connection problems in Windows 10. The problem is sometimes you will have a yellow triangle (no internet access) as your network icon. It’s just showing you that there is no connection or the connection is unidentified. The fix is so simple, you just have to reset winsock catalog to default settings. You need to run two commands in CMD as administrator, and then restart your PC. So, let’s start.

Method 1: Reset Winsock Catalog and IP Settings

Go to the Start menu and type in CMD. Hover over the program and select “run as administrator” on the right

This is a command prompt, which we have opened as administrator. We have an internet issue, so the first thing we need to do is reset winsock catalog by typing:

netsh winsock reset catalog

Hit Enter and it will show you a message like “Successfully reset the Winsock Catalog”. Also, it says that you must restart the computer, but we are not going to do this right now.


We just need to run another command to reset TCP/IP stack. Just type in:

netsh int ip reset reset.log

and then hit Enter.

netsh winsock reset windows 10

It says that resetting is failed and access is denied. You don’t have to worry about, it’s normal.

Method 2: Reset TCP/IP Stack and Renew IP

Open the Command Prompt as administrator again via search icon near Start. Input the following lines (wait to finish a process after typing in each one):

netsh winsock reset

netsh int ip reset

ipconfig /release

ipconfig /flushdns

ipconfig /renew

Method 3: Use the Network Troubleshooter

Windows has some instruments for fix unobvious Internet problems. One of them is Network troubleshooter.

  1. Open the “Windows Settings” via Win + I hotkeys.
  2. Select the “Network & Internet” section.

  4. Select the item with your problem and follow the instructions.

Now you just need to restart your PC and after that you will see that everything is OK.

If none of the methods helped, then pay attention to the following nuances:

  • Make sure that the connection of the Internet cable to the computer is correct and complete;
  • Make sure that the Wi-Fi connection is active on both the laptop and the router.

If the problem with the Internet connection was immediately after installing Windows or the first start of the PC, there is a small probability that the problem is in the network card driver (or rather, its absence). To do this, you need to download it from the manufacturer’s website on USB Flash and install it manually.

Also scan your computer for malware and viruses, which can often block or restrict Internet access.

That’s it. If you have any questions, free to leave them in the comments section below.

  1. Does this fix the real problem of not having internet access or just the NCSI (network connection status indicator) icon?

  2. I have a simple P2P across 4 machines, all wired, not WiFi, all win 10, but a very mixed access to the various / partitions directories. Some Full access, some machines all partitions shown but with a Win NO Access dropdown barring access. I believe I have rightly set permissions as Full to myself and full to everyone, Win lists a lot of fancy would be ACL’s which I don’t understand. Yes and Security is set likewise. In an effort to allow full access I have opened about everything up, dangerous but I’m baffled and would appreciate assistance.
