TCP Reset

In case of a missbehaving internet connection, it is often helpful to do a reset of the underlying networking stack to its default value.
This also helps on stuck internet connections, where you didn’t change anything.

Also some apps install and register components to the networking part of windows and then, due to some bugs, stop the whole communication.
By design, components are able to place themselves into a list, where each of the items need to pass the networking data to the next one…
If one of the items in the list is broken, then the data dissapears silently like into a black hole.
Luckily there is also a way to remove these broken components from the list and repair the list, so the networking data gets passed as it should.

This is how:

  1. Press the Windows Key and the X key on your keyboard to open the admin menu on Windows 10 and Windows 8.
  2. Click on “Command Prompt (Admin).
  3. Now write the following commands one by one and press Enter after each one.
    • ipconfig /flushdns
    • nbtstat -R
    • nbtstat -RR
    • netsh int reset all
    • netsh int ipv4 reset
    • netsh int ipv6 reset
    • netsh winsock reset
  4. Not restart your Windows and most networking problems should be fixed

Please always do a backup before altering system components…
