It can be a frustrating experience if your Internet connection is not working when you need it the most, or if it dies quite often and especially in situations where it is inconvenient. Troubleshooting the Internet connection can be quite the daunting task.

Depending on the connection used, some users may try and power off their modem or router straight away for 30 seconds or so to resolve things, while others may simply wait and do nothing or try to dial in again if they are using a dial-up connection.

Powering off the modem or router works in many cases, especially if the issue is on your end and not the provider's fault. Then again, there are other possibilities why your Internet may not be working right now.

NetChecker provides you with the means to check the status and health of your Internet connection, and repair or fix connectivity issues that it discovers during the connectivity tests.

The application uses Windows Shell utilities for that and no third party tools, and since it is using a command line script to display things, it is pretty fast and stable as well.

The program displays options to you on start. If English is not your language of choice, press 4 to switch to a different interface language.

You can press 1 to check the status of your Internet connection, or 2 to check the Internet connectivity health. The difference? The status checks if you are connected to the Internet and returns either yes or no. The health check on the other hand tests if the Internet connection itself is reliable or causing issues like packet loss.

If issues are discovered, NetChecker offers to resolve them for you right away. How depends entirely on the issue that is experienced:

  • If your computer is disconnected from the Internet, it will run additional tests to find out why that is the case.
  • Depending on the outcome of that check, it may detect issues with the computer's network connection or come to the conclusion that the services of your Internet Service Provider are down.
  • The health check provides additional information that you may find useful. It may suggest for instance to update your router's firmware or replace it if packet loss is detected between hop 0 (network card) and hop 1 (the router).

It should be clear that the program cannot resolve all Internet connectivity issues that you may experience.  It may however be helpful to you if you are experiencing issues that you cannot fix on your own. Note that it is able to resolve issues that you have with wireless and wired broadband connections, but that it cannot be used to text and repair dial-up or mobile Internet connections.

The program is compatible with all versions of the Microsoft Windows operating system starting with Windows XP up to the latest version.

    Fortunately you need a screenshot delay in Linux systems only to make a popup menu or window screenshot. Because Linux systems close all popup’s menus when you click a Print Screen button. Sad but Linux systems are mostly developer friendly systems than user friendly.

    Thank you! ShareX is my favorite free screenshot program, and this will make it more user-friendly.
