There is many reasons causing issues on Internet connectivity, and spikes of pings. One of them it the corruption of TCP/IP stack, due to various installations of softwares using (or changing) network settings/configuration, DNS issues or network issues after installing VPN or firewall or after removing malware/virus. This is how you can fix the problem of spikes of ping. Windows Vista/7/8/10 - Open elevated command prompt (in search box type "cmd" and right click on command prompt programm - "Run as Administrator") Then type the following commands: 1 - Reset winsock catalog to default. C:\WINDOWS\system32>netsh winsock reset 2- Reset TCP/IP C:\WINDOWS\system32>netsh int ip reset 3 - Force to give up lease - send DCHP release notification. C:\WINDOWS\system32>ipconfig /release 4 - Tell DHCP server that your PC want to join network and need new IP address. C:\WINDOWS\system32>ipconfig /renew 5 - Clear DNS cache. C:\WINDOWS\system32>ipconfig /flushdns 6- Restart the computer. Here you start with a fresh and clean new TCP/IP stack ---------------------------------- Other topics related to lag issues / How to fix : Edited May 31, 2020 by Scarface Update reset TCP/IP command 5 1 2 4 Quote Link to comment Share on other sites More sharing options...
