NetChecker: repair Internet connection issues

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.

    I prefer to use “ Windows Repair” to fix Errors on My PC, include Internet Connection issues.

    scratched my head
    * seems like hoax: it is simple 361-line batch file packed with 7z SFX Builder into exe and what is in turn made installer with nsis. it uses three windows built in tools (ping, netsh, ipconfig) and pings google public dns ( check yourself the source from or unpack the exe!
    * calling script to software is IMHO odd-looking!
    * extremely painful, unconvinient navigation and usage: needs typing in keyboard (what else to expect from batch menus)!
    * there are plenty of freeware GUIs for such tasks or standalone utils (like etoolz)
    * simple ways to screw the “program”: undefine system and user temp (or just make them unaccessible): so called “program” needs to unpack the bat before running it; rename/delete/move outside defined path cmd.exe and used utils, prohibit running cmd.exe, rename/delete *.bat.extension, etc. every malware can protect itself with such actions: and no help from so-called “program” at all!

    ok, i don’t even discuss the matter why pack bulk batch file into exe!

    A whole setup-routine for a batch-file?

    Seems to work but why not package it as a portable app?

    BTW after running the setup.exe you can copy the NetChecker folder to do just that… why the installer I don’t know, there doesn’t appear to be any spyware or crapware included.

    I’ll give it a shot. At&t has replaced my uverse modem at least 4 times in less than 2 years. Even with WiFi and Ethernet adapters.

    Sorry Martin,
    but we left the stoneage behind us, a long time ago.
    Today those “apps” are useless, as they can only check the endpoint and not the various hops (like soho-router) in between.

      I love how, because *you* don’t find a program useful (ping/tracert), it’s useless and stone age.

      They are still perfectly valid tools for proving connectivity and basic diagnosis. Just because I can download a 30mb software package and install it to do 300 other things, doesn’t mean it’s a) what I need or b) that it does seem the job any better.

      Sometimes the simplest tool is the best.

    Sorry, but I vote this “Most worthless app ever”. Ping and Tracert commands are already built into the OS. Why would anyone need this? Even the most entry-level computer user would find this app worthless.

      It is not only running those commands, it is also offering suggestions on how to resolve issues with your Internet connection. Plus, it attempts to repair issues that you may be experiencing.
