Reset TCP/IP Stack

Computer communication via internet only can work if TCP/IP working properly. I’m sure you have seen after many ipconfig/renew/release and flushdns and REBOOT still PC cannot get IP. In my experience this is related to corruption in TCP/IP and of course you need to check the cable or WIFI is connected before all of this 🙂

Anyway here is how to reset those corrupted TCP/IP stack and make sure to reboot the PC after reset and RUN the command prompt in ADMIN mode.Also if you have static IP, remember to note them down, because this will wipe those out!

Before all of this in my experience resetting socket also can fix many ip stack related issues and here is the command.

netsh winsock reset

Reset the ipv4

netsh int ip reset

if you want to reset ipv6

netsh int ipv6 reset

If you want to re-install the stcack,

  • SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
  • SYSTEM\CurrentControlSet\Services\DHCP\Parameters

END of the RESET.
